BACKGROUND: Recently I discovered a nifty Javascript function that counts the like values of an index array and returns as its value an object whose property-value pairs consist of a single repeated value and its corresponding frequency. Unfortunately, I am having trouble understanding how the function works. As I have adapted it to fit my own needs I have changed the variable names. Indeed, this change may be the source of my own confusion. The FUNCTION: function dateCounter(dates) { return dates.reduce( (countDates, date) => { countDates[date] = ++countDates[date] || 1; return countDates; }, {} ); } REQUEST: Please write in plain English what the so-called reducer function of the reduce( ) function is achieving with each iteration. I am baffled. Roddy

I am needing to convert an String input into an Integer. But before converting the String input, i have to do a validation that the String input can be converted to a numeric value. So If it cannot, i need to log a message saying “This cannot”. Then log another new log statement on the next line saying “be a number”. I understand I need a parseInt and isNan and if else statements but I am confused on exactly how they are implemented. I am new to javascript.

I am designing a Sharepoint page with script editor. I have an image which I have used area tag on. So with onmouseover another image pops up and it reverts back onmouseout. I further want to use another area tag on this new image onmouseover where I can add area tags on this new image. Something like a nested image map. For description sake. I will use script from w3schools. <img src="planets.gif" width="145" height="126" alt="Planets" name="myname" usemap="#planetmap"> <map name="planetmap"> <area shape="rect" coords="0,0,82,126" onmouseover=myname.src="C:\Users\Quabynar\Pictures\sun.gif" ; onmouseout=myname.src="C:\Users\Quabynar\Pictures\planets.gif"> <area shape="circle" coords="90,58,3" href="mercur.htm" alt="Mercury"> <area shape="circle" coords="124,58,8" href="venus.htm" alt="Venus"> </map> I expect to put another map with area tags on the sun.gif when onmouseover where I can use href to say a link about description the Sun. I don't seem to get around it.

Hey guys, I know that this is quite a longshot but I hope that there is someone here that can help me. We've had problems with our Store Locator on our homepage for quite a long time since it was missing an API Code (which we got today). The site I'm talking about is this: http://www.melon-helmets.com/en/stores The Problem is: I don't know where to put the API. There is this line of code <script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script> My guess was that I'd have to enter the API key after js?, by adding key=ourkey. It does display the map without an error afterwards, unfortunately it always asks me to enter a zip code or adress, even though I did so. (Tried City/Adress/ZIP Code) Can anyone help me? (I'm fairly poor at html/css/js) Thank you!

I tried including the 'tab.html' and ‘content.html’ into my 'index.html' (using w3school code: how to include HTML, found at: https://www.w3schools.com/howto/howto_html_include.asp), but the javascript and css elements do not work. The buttons don't work as intended. Look at: https://rads-198409.appspot.com If you minimize the browser window, the tab is supposed to change to a drop-down menu, but the button does not work at all. I have checked the individual pages and they seem to work just fine, just not when they are combined. Am I doing something wrong? Could someone help? All the code I used is from w3school and I have only modified the file names (tab.html and content .html to point to the right files). Below are links to the code: Code for ‘tab.html’ - https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_topnav Code for ‘content.html’ - https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_collapsible_symbol Code for ‘index.html’ - https://www.w3schools.com/howto/tryit.asp?filename=tryhow_html_include_2

Hi every one, My name is Antoine and I am trying to get all the pictures from a Facebook Page and Instagram Page. I've tried to make a jquery request like $('exemple').load('https://www.facebook.com/pg/stuffedfoxes/photos/ #id'); But it's not working because i don't have any direct id (embedded on the img container). My goal is to get all the 'http' directory of the images and to put them on my web page with my own css code. /* I don't want to use any API*/ Is it possible to load the entire page and filter all the information i need and erased all the others ? /* I'm open to all the solutions excepted if they are using API*/ THANKS PS( sorry for my miss takes im FR ; )

I have used the script for creating an accordion from w3Schools . I would like to add a button somwhere on the page that would collapse all that are open. Even if it is just a reload of the page which would work. <script> var acc = document.getElementsByClassName("accordion"); var i; for (i = 0; i < acc.length; i++) { acc[i].addEventListener("click", function() { this.classList.toggle("active"); var panel = this.nextElementSibling; if (panel.style.display === "block") { panel.style.display = "none"; } else { panel.style.display = "block"; } }); } </script> Please help. I am definitely a newbie. Linda

Hello, With reference to your "Responsive TopNav" example here: https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_topnav it works fine for the most part, except that when the "hamburger" icon is used it does not close down again after making a selection. I have included my own slightly modified version of your example, simplified so there are only "home" and "news" menu items, and the hamburger icon will appear when reducing the width below 1000px. How can this be modified to collapse the hamburger links upon making a selection? Thanks...

Hay can someone offer some input(it's definitely not mobile friendly what I wrote) in regards to JavaScript and the html form document, I can't recalls the relationship while testing the JavaScript logic, any inputs welcome.

Hi everyone. Before I want to say, Im trying to make a project Raspberry PI 3 and Nodered. I'm logging my data from device to Litesql everything is ok. I just want to take this data from db and make a chart for a specific time, like today, yesterday, last week, last mont, last year. I found a code, and need to change this code for my project in javascript. Can some one help me. My db name is Test and column name is Value This code is working code, which is I take in internet , and I changed just db name and source. // This will handle any device and any attribute as long as it is in the DB var p_30d = 1000*60*60*24*30 ; //30 Days var p_7d = 1000*60*60*24*7 ; //7 Days var p_1d = 1000*60*60*24 ; // 1 Day var d = new Date(); var current = d.getTime(); var today0h = d.setHours(0,0,0,0); var day = d.getDay(); var monday0h = today0h - (day + (day === 0 ? -6:1)) * p_1d; var fromdate = 0; var enddate = 0; var sql = []; var sourcelist = []; var aggrlist = []; var title = ""; // Get the period and the list of data sources // also set some default values if one or the other does not exist yet sourcelist = context.get("sourcelist"); if (sourcelist===undefined) { // if running for the first time sourcelist = []; } aggrlist = context.get("aggrlist"); if (aggrlist===undefined) { // if running for the first time aggrlist = []; } fromdate = context.get("fromdate"); if (fromdate===undefined) { // set the period to a default if it is not selected yet fromdate = current-p_1d; } enddate = context.get("enddate"); if (enddate===undefined) { // set the period to a default if it is not selected yet enddate = current; } switch(msg.topic) { case "period": switch(msg.payload) { case "today": fromdate = today0h; enddate = today0h+p_1d; break; case "yesterday": fromdate = today0h-p_1d; enddate = today0h; break; case "thisweek": fromdate = monday0h; enddate = monday0h+p_7d; break; case "lastweek": fromdate = monday0h-p_7d; enddate = monday0h; break; case "last24h": fromdate = current-p_1d; enddate = current; break; case "last7d": fromdate = current-p_7d; enddate = current; break; case "last30d": fromdate = current-p_30d; enddate = current; break; } context.set("fromdate",fromdate); context.set("enddate",enddate); break; case "datasource": if (msg.payload==="delete") { // remove all previous data sources sourcelist = []; } else { sourcelist = context.get("sourcelist"); if (sourcelist===undefined) { // if running for the first time sourcelist = []; } sourcelist.push(msg.payload); } context.set("sourcelist",sourcelist); break; case "aggrsource": if (msg.payload==="delete") { // remove all previous data sources aggrlist = []; } else { aggrlist = context.get("aggrlist"); if (aggrlist===undefined) { // if running for the first time aggrlist = []; } aggrlist.push(msg.payload); } context.set("aggrlist",aggrlist); break; case "minus1w": fromdate = fromdate-p_7d; enddate = enddate-p_7d; context.set("fromdate",fromdate); context.set("enddate",enddate); break; case "plus1w": fromdate = fromdate+p_7d; enddate = enddate+p_7d; context.set("fromdate",fromdate); context.set("enddate",enddate); break; case "minus1d": fromdate = fromdate-p_1d; enddate = enddate-p_1d; context.set("fromdate",fromdate); context.set("enddate",enddate); break; case "plus1d": fromdate = fromdate+p_1d; enddate = enddate+p_1d; context.set("fromdate",fromdate); context.set("enddate",enddate); break; } // Regenerate the SQL statements // Run through the data source list an generate the SQL statements sql = []; if (sourcelist.length>0) { for (var i = 0; i < sourcelist.length; i++) { var parts = sourcelist[i].split("/"); sql.push({ topic: "SELECT * FROM sensor_data WHERE device='"+parts[0]+"' AND sensor='"+parts[1]+"' AND epoch >= " + fromdate + " AND epoch <= " + enddate }); } } if (aggrlist.length>0) { for (var i = 0; i < aggrlist.length; i++) { var parts = aggrlist[i].split("/"); sql.push({ topic: "SELECT * FROM sensor_aggr WHERE device='"+parts[0]+"' AND sensor='"+parts[1]+"' AND epoch >= " + fromdate + " AND epoch <= " + enddate }); } } if (sql.length===0) { // Dummy select that returns nothing to clear the chart sql.push({ topic: "SELECT * FROM sensor_data WHERE device='xxxx'" }); } // set the completed flag for the join node later sql[sql.length-1].complete=true; // pass along the email flag to redirect the flow later if (msg.topic==="email") { sql[sql.length-1].email=true; } // Generate report title if (sourcelist.length===0 && aggrlist.length===0) { title = "No data source"; } else { if (sourcelist.length!==0) { title = title + sourcelist.toString()+ ", "; } if (aggrlist.length!==0) { title = title + aggrlist.toString()+ ", "; } title = title.substring(0,title.length-2); title = title + " | "; var d = new Date(); d.setTime(fromdate); var yyyy = d.getFullYear(); var mm = d.getMonth() < 9 ?

Hi everyone, I'm trying to create the look like "paginate data page", but it is not. I set up the file to insert in website by iframe, but I need to find a way to make clicked data like click the checkbox, then click on next, go to next file in iframe, then come back, stay checked in checkbox. Do you understand what I mean? I'm not fluent in English, my prime is American Sign Language.

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(); }

CONCERN: The following function does what it is suppose to do -- namely, select at random and without duplication a given number of elements from an array of elements. However, I fear that it is hopelessly awkward and would like your professional assessment of its construction. You will likely not find another like it on the internet, but parts of it were obtained therefrom. function selectCubes(gates) { function onlyUnique(value, index, self) { return self.indexOf(value) === index; } var cubes = ['cube_one', 'cube_two', 'cube_three', 'cube_four', 'cube_five', 'cube_six', 'cube_seven']; var selectedCubes = []; var filteredCubes = []; var n = 0; while (n < gates) { selectedCube = cubes[Math.floor(Math.random()*cubes.length)]; selectedCubes.push(selectedCube); if (filteredCubes.length < gates) { var filteredCubes = selectedCubes.filter(onlyUnique); n++; } } return filteredCubes; } console.log('selectCubes(3):' + selectCubes(3)); Please comment and have a great weekend!

Hi, i make one but it will be many line same, like this with 20. document.getElementById("Test1").value = Dotoff; document.getElementById("Test2").value = Dotoff; document.getElementById("Test3").value = Dotoff; i wonder can it make all id in one? i tried it: document.getElementById("Test1","Test2","Test3").value = Dotoff; but it didn't work well, only Test1 change. some know how make all 20 in one? it can save me lots space/line ;)

I'm trying to create a script that contains an if/else statement that uses an outside input to change the color of a box in the html file. Currently I am not seeing any changes, so right now I'm checking if the script is even being noticed and ran. I'll admit that I'm not very good at this, so I apologize if these are really simple problems to fix or that they've been fixed before and I missed it when searching for other posts. If it's the latter, could you send me a link. Placement: Currently the script is inside the a style tag, and both are outside the body. Should I not have it in the style tag? Should I keep it outside of the body? If the issue is placement, where should I place it. Currently the if/else statement is not in a function. Does it need to be in a function? If so, how should I set it up so the function gets called every time, but does nothing until the if condition is met? if I don't need it to be a function to run this, how else can I set it up so it will run? Here's the part of the code that I'm working on, Ignore the contents as all I'm looking for is how to get the script to be noticed and ran. <script= text/javascript> var StopTimePivatic = [[175]]; if (StopTimePivatic != 0){ #b[[141]]{ style.background-color= silver; } } else{ #b80, #b81, #b82, #b83, #b84, #b85, #b86, #b87, #b88, #b89, #b90 { style.background-color = Yellow; style.color = black; } #b0, #b1, #b2, #b3, #b4, #b5, #b6, #b7, #b8, #b9, #b10, #b11, #b12, #b13, #b14, #b15, #b16, #b17, #b18, #b19, #b20, #b21, #b22, #b23, #b24, #b25, #b26, #b27, #b28, #b29, #b30, #b31, #b32, #b33, #b34, #b35, #b36, #b37, #b38, #b39, #b40, #b41, #b42, #b43, #b44, #b45, #b46, #b47, #b48, #b49, #b50, #b51, #b52, #b53, #b54, #b55, #b56, #b57, #b58, #b59, #b60, #b61, #b62, #b63, #b64, #b65, #b66, #b67, #b68, #b69, #b70, #b71, #b72, #b73, #b74, #b75, #b76, #b77, #b78, #b79 { style.background-color = red; } } </script> </style> <body onload="bundle()"> As I said previously, If as similar problem to this has been solved, please let me know where i can find it.

BACKGROUND: Recently I had occasion to make a search on my own website using the Newsletter search engine. What I discovered was the most bizarre of behaviors. I could perform one search in Japanese and then no more. In other languages such as French, German, and English I could perform as many searches as I liked -- even repeating the same words more than once -- and I always I was able to produce the expected result. Mind you, this bizarre one-find-stop--all-further-finds behavior in the Japanese language was not the case when I first installed my search engines. Now, I have checked my PHP error.log file and found nothing related to this problem. I have also checked that the parameter value of the AJAX call is being properly passed; here too there is no unusual behavior. This bizarre behavior was not always the case. It appears to have begun taking place all of its own. Any ideas? Roddy

BACKGROUND: I am baffled by the failure of this code to display "Return User" when the browser page is refreshed or the browser page is closed and then reopened. The vslue of the console.log(localStorage) displays: Storage { return_user: "true", length: 1 } CODE: const output = document.querySelector('.output'); if (typeof localStorage !== "undefined") { var localStorage = window.localStorage; if(localStorage.getItem("return_user")) { output.innerHTML = "Return User"; } else { output.innerHTML = "New User"; localStorage.setItem("return_user", true); console.log(localStorage); } } else { output.innerHTML = "Sorry, local storage is not supported."; } QUESTION: Any ideas?
