  1. Hey, I am a beginner in desperate need of help. I tried to build a slideshow using the code that dsonesuk provided here: http://w3schools.invisionzone.com/topic/55499-combine-the-manual-and-automatic-slideshow-script-into-one-script/page/2/ I wanted to strip it of parts that I don’t need and add some small modifications. What’s the goal? (See image below) An automatic slideshow with „index indicators“ that can manually be triggered. The active one is highlighted and if you hover over any of the indicators, the slideshow stops until unhovered. So far all features are provided by dsonesuk’s code. I wanted to add a few visual tweaks, animations, a bigger hitbox for the indicators and throw out the code that I don't need. What are the problems? I have been trying to build this slideshow for two days now and my motivation has taken a little bit of a hit. While working on it, some of the elements seem to behave unexpectedly. It might also have to do with the Firefox browser developer tool I am using since some issues don't occur if I scale the browser window by hand but only when mobile presets of the browser are used (using Firefox Quantum 68.0.1, 64-Bit). The version I am showing you right now has some bugs I just don’t know how to fix: The whole .slideshow is not positioned in the center as it should be (visible in screen sizes wider than 1280px). This is because the .slideshow is an inline-block element. But if I set it to just inline or block, the slideshow glitches into the following div (in larger screen sizes). The smaller you make the browser size, the more #myslideFrame expands in height, messing with the positioning of the whole slideshow. I think the JS is responsible for that, but I don’t know how to fix it. Strangely, reloading fixes the issue (until browser window gets resized from big to small again). I can’t get the index indicators back „over“ the img. Any thoughts on the hitbox for the index indicators? I can’t get them to work either. What's the code? You can find the HTML, CSS and JS files attached beneth. The download section doesn't seem to manage folders very well (or at all). But the files "img1.jpg", "img2.jpg" and "img3.jpg" need to go into a folder called "img" in order for the code to work properly. There are a few bits of code that I am not entirely sure if they are still necessary (remaining from dsoneuk's code). As I said I am still learning and this thing grew over my head quickly. Thanks! fact.html script.js style.css .DS_Store
  2. Full2018AF.zip Hey this is a very simple mern APP for beginner to refer for. On this example I have used a past paper of a college
  3. I'm basically a coding amateur and need help! I used this page to find an accordion that works well for what I need (I'm looking for an accordion that can have all open at once) and am basically using this permutation, edited only for content & style. Is there a way to start with them all open instead of all closed? The simpler the better for this frustrated amateur! Thanks!
  4. Hi I have a page with multi-column rows, and I want to filter the rows. This is what I have right now <div class="container-fluid"> <div class="row"> <div class="col-md-2"><button class="timebutton" disabled="disabled" type="button">7:30am</button> </div> <div class="col-md-10"><div class="description-container"><details> <summary><span class="txt-lg" style="font-weight: bold;">Registration and Breakfast</span> <span style="color: #f37322; font-weight: bold;">Main Room</span> &nbsp; Continental breakfast served at registration.</summary> </details></div> </div> </div> <div class="row"> <div class="col-md-2"><button class="timebutton" disabled="disabled" type="button">4:30pm</button> </div> <div class="col-md-10"><div class="description-container"><details> <summary><span class="txt-lg" style="font-weight: bold;">Name of the First Session at the Event</span> <span style="color: #f37322; font-weight: bold;">Room 27363</span> | <span style="color: #36454f; font-weight: bold;">Joe Bloggs</span> &nbsp; <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec hendrerit ante magna, id fringilla ex venenatis vitae. Etiam fringilla placerat lectus non tempus. Suspendisse sollicitudin, lorem quis finibus eleifend, velit risus ornare magna, et tristique tellus est ac purus...</summary> Sed vel felis nibh. Phasellus auctor, ante vestibulum egestas placerat, nunc nulla aliquam tellus, non posuere sapien erat ut nibh. Cras iaculis mollis pretium. Duis ante enim, interdum ac nulla nec, euismod accumsan libero. Cras a condimentum dolor. Donec porttitor et sapien vel pretium. Vestibulum porta laoreet massa, a luctus eros rhoncus ac. Duis viverra turpis in lectus eleifend, quis iaculis.</p> </details></div> </div> </div> </div> </div> So each row is a time element and a descriptive text area element. Both need to be counted as one element, so that when a filter is applied, both are included. Mainly, I'm wondering where I put the div class for the filter. Thanks! Thanks
  5. I am trying to switch two divs on an onclick command to a search button. One div should replace the other entirely. I have tried to do this two ways: 1) make Div 1 width = 0 when Div 2 width = 100%, and vice versa 2) make Div 1 display = none when Div 2 display = block, and vice versa. My problem is that while both make Div 1 disappear when Div 2 is visible, and Div 2 disappear when Div 1 is visible, in both cases Div 2 remains stacked below the area designated for Div 1, and it should replace its position entirely. Any suggestions why this might be doing this and/or, is there a better way to accomplish this than just changing the CSS? I am including the JS, HTML, and CSS attending this problem. Thanks ahead of time: JS (from Option 2) function getSearch() { document.getElementById("searchcontainer").style.display = "block"; document.getElementById("blogcontainer").style.display = "none"; } HTML <div id="rightcontainer"> <div id="searchbox"> <form> <input type="text" placeholder="Search..." required> <input id="cardib" type="button" value="Search" onclick="getSearch()"> </form> </div> <button id="down" onclick="scrollDown()" onmouseenter="Highlight1()">&#9660</button> <button id="up" onclick="scrollUp()" onmouseenter="Highlight2()">&#9650</button> <div id="blogcontainer" onmouseover="RollOff1()" onmouseout="RollOff2()"> <div class="postcontainer"> <div class="thumb"></div> <div class="topblock"><div class="titleblock">Valentines and Rats</div> <div class="moreblock">MORE ></div> </div> <div class="block"> <div class="date"><p>February 14, 2016</p></div> We celebrate Valentine's Day while I battle rats in the coop. </div> </div> <div class="postcontainer"> <div class="thumb"></div> <div class="topblock"><div class="titleblock">Valentines and Rats</div> <div class="moreblock">MORE ></div> </div> <div class="block"> <div class="date"><p>February 14, 2016</p></div> We celebrate Valentine's Day while I battle rats in the coop. </div> </div> <div class="postcontainer"> <div class="thumb"></div> <div class="topblock"><div class="titleblock">Valentines and Rats</div> <div class="moreblock">MORE ></div> </div> <div class="block"> <div class="date"><p>February 14, 2016</p></div> We celebrate Valentine's Day while I battle rats in the coop. </div> </div> <div class="postcontainer"> <div class="thumb"></div> <div class="topblock"><div class="titleblock">Valentines and Rats</div> <div class="moreblock">MORE ></div> </div> <div class="block"> <div class="date"><p>February 14, 2016</p></div> We celebrate Valentine's Day while I battle rats in the coop. </div> </div> <div id="searchcontainer" onmouseover="RollOff1()" onmouseout="RollOff2()"> <div class="postcontainer"> <div class="thumb"></div> <div class="topblock"><div class="titleblock">OMG</div> <div class="moreblock">MORE ></div> </div> <div class="block"> <div class="date"><p>February 14, 2016</p></div> We celebrate Valentine's Day while I battle rats in the coop. </div> </div> <div class="postcontainer"> <div class="thumb"></div> <div class="topblock"><div class="titleblock">OMG</div> <div class="moreblock">MORE ></div> </div> <div class="block"> <div class="date"><p>February 14, 2016</p></div> We celebrate Valentine's Day while I battle rats in the coop. </div> </div> <div class="postcontainer"> <div class="thumb"></div> <div class="topblock"><div class="titleblock">OMG</div> <div class="moreblock">MORE ></div> </div> <div class="block"> <div class="date"><p>February 14, 2016</p></div> We celebrate Valentine's Day while I battle rats in the coop. </div> </div> <div class="postcontainer"> <div class="thumb"></div> <div class="topblock"><div class="titleblock">OMG</div> <div class="moreblock">MORE ></div> </div> <div class="block"> <div class="date"><p>February 14, 2016</p></div> We celebrate Valentine's Day while I battle rats in the coop. </div> </div> </div> </div> CSS #blogcontainer{ width: 100%; height: 90%; float: left; overflow-y: hidden; padding: 0; position: static; float: left; margin-left: 0; margin-right: 0; margin-bottom: 0; } #searchcontainer{ width: 100%; height: 90%; float: left; overflow-y: hidden; padding: 0; position: static; float: left; margin-left: 0; margin-right: 0; margin-bottom: 0; } #rightcontainer { height: 100vh; width: calc( 100% - 20vh - (.678*(100%-20vh))); position: fixed; overflow: hidden; background-color: gray; margin-left: calc((.678*(100%-20vh)) + 20vh); float: left; margin-right: 0; }
  6. hi add please MutationObserver source mozilla
  7. Hello potential helpers, im currently having issues with firing an ajax request inside of another ajax request. Heres my code: Im not getting "alert(content)" Condition if(shop[1] == "gserver") and if(name.includes(shopname) == true) are definetly true. The function is correctly called as well. No Im not using jquery for reasons. Anyone has an idea why the 2nd requests isnt fired? Is it not waiting for the first one to finish? function initiate_shop_game(shopname) { var xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function() { if(this.readyState == 4 && this.status == 200) { var obj = this.responseText; var array = eval("[" + obj + "]"); var r = 1; for(var i = 0; i < array.length; i++) { for(var x = 0; x < array[i].length; x++) { var shop = array[i][x] + ''; shop = shop.split(","); if(shop[1] == "gserver") { var name = shop[2]; var imgname = shop[7] var shopvalues = shop[3].split("{%TEND%}"); var minslots = parseInt(shopvalues[1]); var maxslots = parseInt(shopvalues[2]); var minram= parseInt(shopvalues[3]); var maxram = parseInt(shopvalues[4]); var pricea = (parseFloat(shop[5]) / 30); var priceb = (parseFloat(shop[6] / 30)); var content = [name,imgname,minslots,maxslots,minram,maxram,pricea,priceb]; if(name.includes(shopname) == true) { var div = document.createElement('div'); div.id = name; var xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function() { if(xmlhttp.readyState == 4 && xmlhttp.status == 200) { alert(content); }; xmlhttp.open('POST',"/template_shop.php", true); xmlhttp.send(); } } } } } } }; xmlhttp.open('POST',"/get_shop_data.php", true); xmlhttp.send(); }
  8. Hello, so at the store page, when in mobile view the top dropdown menu doesn't work. When I delete parts bit for bit in the footer PHP file the menu will still not work. If I delete everything in the footer PHP file it will still not work. But if I completely change the PHP file name so it isn't linked to the store page at all, the dropdown menu works perfectly fine. I find this really weird and I can't figure out how to fix it. Can somebody help?
  9. First of all, I'm no way near any skilled "programmer" or website builder, I mostly just copy things and modify the styles and stuff! So this is probably a nooby question, you have been warned. I've this website I'm building for a school project and I've a few problems left and I've given up trying to fix them, I need to start working on other stuff. First of all so am I trying to get this slider between the three pictures and the navigation bar in the supposedly start page, but the animation disappear when you put it in and I don't think the autoplays work either. This is the main thing I'm trying to do. Secondly, When you go on mobile view and press the dropdown menu it doesn't seem to find the script, which i don't understand why. In the header I have <script src="/online-store-header/js/flertdown.js"></script> and the body I've the code <a href="javascript:void(0);" style="font-size:25px;position: absolute; top: 65px; right: 0; border: 0;" class="icon" onclick="specificName()">☰</a> The console returns this error: Uncaught TypeError: Cannot read property 'className' of null at specificName (flertdown.js:3) at HTMLAnchorElement.onclick (final.html:195) Dropdown js code Any help would be really appreciated, i really need to be done this site soon :)) And I'm really sorry if the index file is totally chaos, elements seems to have a life of their own and come back and reproduce to multiple of the same element after I've deleted them, I've lost control of what i've created (or copied)
  10. So I've searched the web and tried for hours now and I'm just giving up. I've this header, and I want it so when you're on mobile it looks like something like this. So when you're on desktop the full menu is in the header and if your're on mobile you get a dropdown menu. Can someone tell me how I do this? Thank you
  11. I want to use a gif I made for my sprite (it would be nice if the gif only played when the character moved) So far, I have a rectangle with choppy character movements. (It would also be nice if I could make the character movement smoother. I watched tons of tutorials but I couldn't find anything that shows how to do what I want to do.

  12. I found w3schools' tutorial for "Image Magnifier Glass" and want to use it on my website for multiple images. But I can only get it to work for one, presumably because it uses document.getElementById(imgID) in the js; I tried changing this to document.getElementsByClassName(names) but that didn't work. I'm not an experienced javascript user so don't know how to resolve, but assume something different needs to go where (names) is at the least. Can anyone help? The only thing I changed in the code is to add a little padding to the img-magnifier-container class. Thank you. <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <style> * {box-sizing: border-box;} .img-magnifier-container { position:relative; padding: 20px; } .img-magnifier-glass { position: absolute; border: 3px solid #000; border-radius: 50%; cursor: none; /*Set the size of the magnifier glass:*/ width: 100px; height: 100px; } </style> <script> function magnify(imgID, zoom) { var img, glass, w, h, bw; img = document.getElementById(imgID); /*create magnifier glass:*/ glass = document.createElement("DIV"); glass.setAttribute("class", "img-magnifier-glass"); /*insert magnifier glass:*/ img.parentElement.insertBefore(glass, img); /*set background properties for the magnifier glass:*/ glass.style.backgroundImage = "url('" + img.src + "')"; glass.style.backgroundRepeat = "no-repeat"; glass.style.backgroundSize = (img.width * zoom) + "px " + (img.height * zoom) + "px"; bw = 3; w = glass.offsetWidth / 2; h = glass.offsetHeight / 2; /*execute a function when someone moves the magnifier glass over the image:*/ glass.addEventListener("mousemove", moveMagnifier); img.addEventListener("mousemove", moveMagnifier); /*and also for touch screens:*/ glass.addEventListener("touchmove", moveMagnifier); img.addEventListener("touchmove", moveMagnifier); function moveMagnifier(e) { var pos, x, y; /*prevent any other actions that may occur when moving over the image*/ e.preventDefault(); /*get the cursor's x and y positions:*/ pos = getCursorPos(e); x = pos.x; y = pos.y; /*prevent the magnifier glass from being positioned outside the image:*/ if (x > img.width - (w / zoom)) {x = img.width - (w / zoom);} if (x < w / zoom) {x = w / zoom;} if (y > img.height - (h / zoom)) {y = img.height - (h / zoom);} if (y < h / zoom) {y = h / zoom;} /*set the position of the magnifier glass:*/ glass.style.left = (x - w) + "px"; glass.style.top = (y - h) + "px"; /*display what the magnifier glass "sees":*/ glass.style.backgroundPosition = "-" + ((x * zoom) - w + bw) + "px -" + ((y * zoom) - h + bw) + "px"; } function getCursorPos(e) { var a, x = 0, y = 0; e = e || window.event; /*get the x and y positions of the image:*/ a = img.getBoundingClientRect(); /*calculate the cursor's x and y coordinates, relative to the image:*/ x = e.pageX - a.left; y = e.pageY - a.top; /*consider any page scrolling:*/ x = x - window.pageXOffset; y = y - window.pageYOffset; return {x : x, y : y}; } } </script> </head> <body> <h1>Image Magnifier Glass</h1> <p>Mouse over the image:</p> <div class="img-magnifier-container"> <img id="myimage" src="http://bartonlewisfilm.com/img_157-229.jpg" width="33%" height="33%"> </div> <div class="img-magnifier-container"> <img id="myimage" src="http://bartonlewisfilm.com/img_287-145.jpg" width="33%" height="33%"> </div> <p>Feel free to change the strength of the magnifier glass when initiating the magnify function.</p> <script> /* Initiate Magnify Function with the id of the image, and the strength of the magnifier glass:*/ magnify("myimage", 3); </script> </body> </html>
  13. Hey there, I have followed the tutorial for the w3 raspberry pi led pwm Gpio controller using node.js (https://www.w3schools.com/nodejs/nodejs_raspberrypi_rgb_led_websocket.asp) unfortunately though it uses internal scripts and stylesheets. I have tried using express.static to set up file hosting but I couldn’t get it to work. I am needing to host additional files for the web server to read. I am fairly new at node.js so it might have been the way I was trying to implement it that caused the issue. Thanks in advance
  14. Being reasonably new at generating javascript, I am trying to create a form where the client enters the State of Birth (Queensland, Victoria, Tasmania etc) and by using javascript the Country of Birth is auto filled with "Australia". I have got to a stage where I can auto fill the Country field with a small js script with either onClick or mouseOver however I am at a loss with the code to be able to fill the Country field by entering the state name in the State field. At 75 I'm running out of brains and would appreciate a little help please. Autofill.html
  15. I am trying to copy form inputs from 3 address fields to corresponding duplicate fields in another section of my form. If I use the following script and html the process works perfectly. <input type="checkbox" id="copy" value="" name="copy" onclick="CopyAddress(this.form)"> <script> function CopyAddress(f) { if(f.copy.checked == true) { f.bstr.value = f.gstr.value; f.bsubcit.value = f.gsubcit.value; f.bstate.value = f.gstate.value; f.bpcode.value = f.gpcode.value; } else { f.bstr.value = ""; f.bsubcit.value = ""; f.bstate.value = ""; f.bpcode.value = "";} } <script> I would like to change the checkbox to a button like so: <input type="button" id="copy" value="Copy" name="copy" onclick="CopyAddress(this.form)"> However once I change to a button, the script will not run and I can't work out why. My limited understanding tells me the fault lies in line 2 of the JS, if(f.copy.checked == true). Can anyone tell me where I am going wrong please.
  16. FIXED IT! I placed my script a little lower on the document! Worked... no clue why tho :/

  20. Dear W3schools community, I want to check if a required input is empty (has more then 0 characters). You guys have any idea what I'm doing wrong? Thanks in advance! If there is no character in input (id="vname") I still get a red "bar" Here's my code: function foobar() { var vname = document.getElementById('vname').value; if (vname.length > 0 && vname != '' && vname != null) { document.getElementById('contact-response').style.color = 'green'; document.getElementById('contact-response').innerHTML = "foo"; } else { document.getElementById('contact-response').style.color = 'red'; document.getElementById('contact-response').innerHTML = "bar"; } } I also tried length, null and '' separately. I also tried doing it with isEmpty(). Also I tried using || instead of &&. Nothing worked yet. Heres my HTML: <div id="wrapper-contact"> <form> <input type="text" id="vname" placeholder="*Vname" required="yes"> <input type="button" onclick="foobar()" value="Senden"> <p id="contact-response"></p> </form> </div>

  22. Hello, this is my first time posting, and I wanted to know how to start of on an id using the W3Schools Tab function.

  24. Hello programmers, Just have met with the above statement which comes with www.veldfiets.nl/whbe2b. I have changed somewhere a thing and mismanaged the smoothscroll in the above way. I cannot find the mistake. Has anybody a clue? It has been a long time ago that I wrestled with the matter and got it working.... Thanks a lot.
  25. Hello. Here is some excerpted code which already works well. ------------------------------------------------------------------------------------------------------- <script type="text/javascript"> function checkForm(form) { if(form.username.value == "") { ... // many more lines </script> <form action="return_to_calling_page.html" onsubmit="return checkForm(this);" id="logonForm" > <p>Username: <input type="email" name="username" autofocus></p> <p>Password: <input type="password" name="pwd1"></p> <p>Confirm Password: <input type="password" name="pwd2"></p> <p><br/> <input type="submit" value="submit"> <button type="button" onclick="javascript:location.href='about_page.html'">cancel</button> </p> </form> ... // many more lines ------------------------------------------------------------------------------------------------------- Then the JavaScript question: The checkForm(form) function only checks input data against invalid character types. But we additionally need to check the logon input values are in the company db. So I tried to write and call a modified function which included the checkForm(form) function. But the new modified javascript function verifyLogon() does not seem to run at all? Currently the following modified code is in use (which does not appear to call verifyLogon() successfully): ------------------------------------------------------------------------------------------------------- <form action="return_to_calling_page.html" onsubmit="return verifyLogon();" id="logonForm" > <script type="text/javascript"> function verifyLogon() { alert("Entered verifyLogon()"); // print something, regardless, but never (yet) seen checkForm(form) // checkForm(form) does not (yet) run from here if(checkForm()) { // if checkForm() returns true, do un/pw lookup in db <?PHP some_php_code1 ?> // run some php, sql find un in db if($stmt1 = true) { // if un query returns true, then... <?PHP some_php_code2 ?> // run some php, sql find pw in db if($stmt2 = true) { // if pw query returns true, then... <?PHP some_php_code3 ?> // run some php, sql view customer account db records }else{ alert("Password not found in company db."); } }else{ alert("Username was not found in company db."); } }else{ document.getElementById("logonForm").reset(); // clears the form form.username.focus(); // sets focus to username field return false // return to form } } </script> ------------------------------------------------------------------------------------------------------- Currently, I am not very concerned about the (if) control logic inside the verifyLogon() function. The plan is to fine tune the (if) logic later once the verifyLogon() is running. Mostly now just want to get the verifyLogon() running at all. Thank you.
