  1. I've got a function that create mesh when you click on another. On the click, 2 or 3 mesh are created and go to their positions. Know i would like to do the reverse function : when the mesh are deployed, and you click anoter time on the mesh, the previously created mesh go back and are removed from the scene. Here is my first function : function sortiSphere(element, obj) { var matStdParams = { roughness: 1, metalness: 0.8, color: element.group, emissive: element.group, emissiveIntensity: 0.5 }; var sphereMaterial2 = new THREE.MeshStandardMaterial(matStdParams); var mesh = new THREE.Mesh(sphereGeometry, sphereMaterial2); mesh.position.x = x; mesh.position.y = y; mesh.position.z = z; mesh.userData.children = element.children; mesh.userData.name = element.label; mesh.userData.rang = element.rang; mesh.userData.def = element.définition; mesh.userData.posx = element.posx; mesh.userData.posy = element.posy; mesh.userData.posz = element.posz; mesh.userData.parent = obj; mesh.userData.cartabs = element.cartabs; mesh.position.normalize(); mesh.position.multiplyScalar(1 / element.rang); mesh.scale.set(1 / (element.rang / 2), 1 / (element.rang / 2), 1 / (element.rang / 2)) mesh.position.x = obj.position.x; mesh.position.y = obj.position.y; mesh.position.z = obj.position.z; var x = element.posx; var y = element.posy; var z = element.posz; new TWEEN.Tween(mesh.position).to({ x: x, y: y, z: z }, 1000) .easing(TWEEN.Easing.Elastic.Out).start(); console.log(mesh); scene.add(mesh); lesMesh.push(mesh) // lines var material = new THREE.LineBasicMaterial({ color: 0xffffff }); var geometry = new THREE.Geometry(); geometry.vertices.push( obj.position, new THREE.Vector3(x, y, z) ); var line = new THREE.Line(geometry, material); scene.add(line); gen1 = []; gen2 = []; gen3 = []; gen4 = []; gen5 = []; obj.userData.bool = true; }; Notice that the mesh contain a information about their state : userData.bool (true if deployed, false if not) Now, how do I tell them to go back ? Here is what I got for now : function deleteSphere(element, obj) { console.log("--- deleteSphere / debut fonction") for (i = 0; gen1.length > i; i++) { if (gen1[i].userData.children) { for (j = 0; gen1[i].userData.children.length > j; j++) { console.log(gen2[i][j]); scene.remove(gen2[i][j]);} } else { scene.remove(gen1[i]) console.log(gen1[i].userData.children) } } }; Thanks for your time
  2. My suggestion is to add HTML DOM element object outerHTML attribute for the JavaScript reference. It seems that most, if not all, the browsers support this attribute. In addition, it is important and basic attribute that new JavaScript developers should know about.
  3. Hello, I try to place meshs on sphere depending on their rank in a json file. I am looking for a way to define the position of my meshs in my loop in order to prevent them to be created on each other. function onMouseGauche(event) { event = event || window.event; if (event.button == 0) { mouse.x = (event.clientX / window.innerWidth) * 2 - 1; mouse.y = -(event.clientY / window.innerHeight) * 2 + 1; // update the picking ray with the camera and mouse position raycaster.setFromCamera(mouse, camera); // calculate objects intersecting the picking ray var intersects = 0; intersects = raycaster.intersectObjects(scene.children); if (intersects.length > 0) { if (intersects[0].object.userData.bool != true) { // Scalar = Scalar + 400; Scalar = Scalar / 1; Scale = Scale / 1; console.log(intersects[0].object.userData) if (intersects[0].object.userData.children) { var loop = 0; intersects[0].object.userData.children.forEach(function(element) { var sphereMaterial2 = new THREE.MeshBasicMaterial({ color: element.group }); var mesh = new THREE.Mesh(sphereGeometry, sphereMaterial2); var phi = ( 2 * Math.PI) var theta = (2 * Math.PI) var x = Math.random() * 2 - 1; var y = Math.random() * 2 - 1; var z = Math.random() * 2 - 1; // if (loop == 0) { // var x = Math.random() * 2 - 1; // var y = Math.cos(theta) * Math.random(); // var z = Math.cos(phi) * Math.random() // } // if (loop == 1) { // var x = Math.cos(phi) * Math.random(); // var y = Math.random() * 2 - 1; // var z = Math.cos(theta) * Math.random() // } // if (loop == 2) { // var x = Math.tan(phi) * Math.random(); // var y = Math.tan(theta) * Math.random(); // var z = Math.random() * 2 - 1 // } mesh.position.x = x; mesh.position.y = y; mesh.position.z = z; mesh.userData.children = element.children; mesh.userData.name = element.label; mesh.userData.rang = element.rang; mesh.position.normalize(); mesh.position.multiplyScalar(Scalar / element.rang); mesh.scale.set(Scale / element.rang, Scale / element.rang, Scale / element.rang) mesh.position.x = mesh.position.x + intersects[0].object.position.x; mesh.position.y = mesh.position.y + intersects[0].object.position.y; mesh.position.z = mesh.position.z + intersects[0].object.position.z; console.log(element) scene.add(mesh); // lines var material = new THREE.LineBasicMaterial({ color: 0xffffff }); var geometry = new THREE.Geometry(); geometry.vertices.push( intersects[0].object.position, mesh.position ); var line = new THREE.Line(geometry, material); scene.add(line); intersects[0].object.userData.bool = true; loop = loop + 1 }); } } } } // ajouter position de caméra actuelle camera.userData.push([Math.round(camera.position.x), Math.round(camera.position.y), Math.round(camera.position.z)]) } Here is the function that draw the sphere meshs. How can i define my coordinates more efficiently? Thank you
  4. QUESTION ONE: Please suggest what might be entered where the three ? marks appear in order to achieve the following goal. THE GOAL: See appear the value of mil in the input control text field and have this value become the value of $_POST['item_encllength'] when the form is submitted. var min = $('#min').val(); var sec = $('#sec').val(); var mil = function(min, sec) { var millisec = ((min * 60) + sec) * 1000; return millisec; } $('#item_encllength').mousedown(mil, function() { $(this).???; }); <input id='min' type='number' value='Minutes'> <input id='sec' type='number' value='Seconds'> <input id='item_encllength' form='rss2_feed' type='text' name='item_encllength'> I have experimented in a variety of ways, but have not been able to find the code necessary to achieve my goal. Perhaps my approach to the problem is inappropriate. Roddy

  6. Evening, I have very, very limited knowledge of javascript, and I've run into a problem I can't seem to resolve. I have an animated hamburger menu, which when clicked/tapped shows a div (that is later to contain an accordion menu). The toggle on/off script works fine, but whenever I add the script to animate the hamburger menu, it seems to override the toggle on/off script and does not work. Can anyone please steer me in the right direction or offer some advice on where I am going wrong. Many thanks. <head> <meta charset="utf-8"> <style> #mob-menu { width: 100%; padding: 50px 0; text-align: center; background-color: lightblue; margin-top:20px; } .container { display: inline-block; cursor: pointer; } .bar1, .bar2, .bar3 { width: 35px; height: 5px; background-color: #333; margin: 6px 0; transition: 0.4s; } .change .bar1 { -webkit-transform: rotate(-45deg) translate(-9px, 6px) ; transform: rotate(-45deg) translate(-9px, 6px) ; } .change .bar2 {opacity: 0;} .change .bar3 { -webkit-transform: rotate(45deg) translate(-8px, -8px) ; transform: rotate(45deg) translate(-8px, -8px) ; } </style> </head> <body> <div class="container" onclick="myFunction(this)"> <div class="bar1"></div> <div class="bar2"></div> <div class="bar3"></div> </div> <div id="mob-menu"> Accordion menu goes here </div> <script> function myFunction() { var x = document.getElementById('mob-menu'); if (x.style.display === 'none') { x.style.display = 'block'; } else { x.style.display = 'none'; } } </script> <script> function myFunction(x) { x.classList.toggle("change"); } </script> </body>
  7. Hello, I have a question about how to send form data to the database, without reloading the entire page. I discovered working with xmlhttprequest. I managed to show text from another file by implementing a javascript function with xhr into my script. I don’t know much about javascript and don’t understand how a javascript form should be added to an existing function. Finally this should run a php script executing the code to add the form data to the database. <!DOCTYPE html> <html> <body bgcolor="grey"> <center> <br><br><br> <div style="height: 200px; width: 600px; border: solid 2px blue;"> <div id="kn_ze"> <form id="my_form" action=""> Give your name: <input type="text" name="fname"> <br> <input type="submit" value="Send" onclick="loadXMLDoc();"> <!-- <button type="button" onclick="loadXMLDoc()">send it</button> --> </form> </div> </div> <script> function loadXMLDoc() { /* document.getElementById("my_form").submit();*/ var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { document.getElementById("kn_ze").innerHTML = this.responseText; } }; xhttp.open("GET", "prophp.php", true); xhttp.send(); } </script> </body> </html> test script to process the form data prophp.php : <?php echo '<br>test code here : '; if (isset($_POST['fname'])) { var_dump($_POST['fname']); // execute mysql queries } ?> 11) How are the form data placed in the existing function? (or should I create a second one? ) Maybe someone can help me out solving it.
  8. Greetings to all in the forum. I'm totally new to AppML which by the way i found very interesting. Followed the tutorial of https://www.w3schools.com/appml/appml_client.asp till the end of it https://www.w3schools.com/appml/appml_database.asp and trying to build the web application by using WebSQL. In the table customers i can delete an existing record and modified it, but i can't add a new one. Every time when i go to New button and adding new customer data, when i press Save button i got an error in Chrome console Uncaught TypeError: Cannot read property 'CustomerID' of undefined at AppML.putRecord (appml.js:527) at AppML.saveRecord (appml.js:593) at HTMLButtonElement.onclick (app2.html:1) Specifically got error in line 527 of appml.js { if (action === "UPDATE") { if (this.data.records[0][this.data.keyField] === "") {action = "ADD"; } } And in line 593 of appml.js this.saveRecord = function () { this.putRecord("UPDATE"); }; My HTML Prototype is the follow <!DOCTYPE html> <html lang="en-US"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type"> <title>Untitled 1</title> <title>Customers</title> <link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css"> <script src="appml.js"></script> <script src="https://www.w3schools.com/appml/2.0.3/appml_sql.js"></script> </head> <body> <div class="w3-container"> <div id="Form01" class="w3-container w3-light-grey w3-padding-large w3-margin-bottom" appml-data="local?model=model_customersform" appml-controller="myFormController" style="display:none;"> <div appml-include-html="inc_formcommands.htm"></div> <p> <label for="customername">Customer:</label> <input id="customername" class="w3-input w3-border"> </p> <p> <label for="address">Address:</label> <input id="address" class="w3-input w3-border"> </p> <p> <label for="city">City:</label> <input id="city" class="w3-input w3-border"> </p> <p> <label for="postalcode">Postal Code:</label> <input id="postalcode" class="w3-input w3-border"> </p> <p> <label for="country">Country:</label> <input id="country" class="w3-input w3-border"> </p> </div> <div appml-data="local?model=model_customerslist"> <h1>Customers</h1> <div appml-include-html="inc_listcommands.htm"></div> <div appml-include-html="inc_filter.htm"></div> <table class="w3-table-all"> <tr> <th></th> <th>Customer</th> <th>City</th> <th>Country</th> </tr> <tr appml-repeat="records"> <td style="cursor:pointer;width:34px;" onclick="appml('Form01').run({{CustomerID}})">&#9998;</td> <td>{{CustomerName}}</td> <td>{{City}}</td> <td>{{Country}}</td> </tr> </table> </div> </div> <script> function myFormController($appml) { if ($appml.message == "ready") {return -1;} if ($appml.message == "loaded") { document.getElementById("Form01").style.display=""; } } </script> </body> </html> Any help it's appreciated, i'm stuck at that point. I've tried some solutions but didn't worked. I have a feeling that something i am missing, cause i'm not an english native speaker. Any solutions? Thanks in advance.

  10. I've inserted a clickable dropdown on my site. In FireFox and Chrome, the menu closes when you click outside the menu. This does not work with Internet Explorer. I have taken this code from w3school.com (the same problem on the page): https://www.w3schools.com/howto/howto_js_dropdown.asp What can I do to make it work on the Internet Expolorer the same as in FireFox and Chrome? Thanks for your help.

    What About Adding Node.js As Another Tutorial In The Server-Side Languages? to complete the chain of JavaScript and to teach the newer, modern and the attractive part of the language...why not? I am not recommending specific framework W3SCHOOLS can choice any of the available, but please the best! WHY ADDING: I am not here to explain the power of Node.js...Please Google this WHY IT'S NECESSARY: Large companies are using and coming to Node e.g...[Google this also ], and large apps are written with it[Do Not Forget Our friend..Google]. not only it's "Popular", but also fast(because of the non-blocking I/O, being V8 based and more[Google!!!]) THANKS FOR: ADDING NODE AS THE THIRD LANGUAGE

  13. BACKGROUND: I am tempted to write something like the following foreach ($non-matches as $key => $val) { echo '<script> $("#' . $key . '").append("<p style=' . '"color:red;">Complete this item!</p>);</script>)'; } QUESTION ONE: Under the assumption that the echo statement is correct would you recommend this as proper programming procedure? If not, please explain why and provide an alternative, more appropriate strategy that would achieve the same objective suggested by the use of a jQuery object ? QUESTION TWO: If it is proper programming procedure, please correct the echo statement so that it will achieve the following: $("#...").append("<p style='color:red;'>Complete this item!</p>"); EDIT: In order to assist you in your response, the PHP variable $non-matches contains a list of values for the id attributes of form input control tags that have been carefully selected through a prior PHP procedure. An alternative approach that is currently under consideration is to create a JSON object, assign it to a Javascript variable, and iterate the resulting object with jQuery.
  14. I recently used PHP's json_encode( ) function to covert an array created with PHP into a JSON encoded object, as the conversion appeared normal, I then assigned the value to a Javascript variable using PHP's echo construct and reproduced it with a JS alert. This too, appeared normal. My difficulty arose when I tried using the jQuery .map( ) method to convert my nested Javascript object into a nested Javascript array. I received the following error message in my Console: TypeError: e is not an Object. (evaluating 't-1 in e') Am I being foolish to believe that I need a nested array when I already have a nested object? If not, is there not a routine to perform this very conversion?
  15. So, I'm really stuck. I know how to make a quiz just fine, with radio buttons, go to the next page, etc., but for our project we have to make the quiz go from one page to the next and hold the answers provided, and then at the end we need to output the result by combining the answers. Essentially it's a personality quiz type thing, rather than a scoring one. My idea is to add 1 each time an answer corresponding to that personality is given, but how to I transfer those values from one page to the next?
  16. Hi. I am familiar with some HTML but my knowledge in Javascript, JQuery and CSS is very limited. I have been learning from examples on the web and making my own changes. Please see the fiddle I am working on below; sorry if the full code is messy! https://jsfiddle.net/djj2c84t/ There are a number of features I wish to implement but I am totally stumped! I have gotten as far as I think I can with the fiddle above and it would be more than appreciated if anyone can provide any help, possibly with any example code and where the code needs to go. When I make a multiple selection from the list, how do I get the results (divs) to show in order of most recent selection at the top? For example, if I multi-selected in the order Nuts, Meats, Vegetables, Fruits, how do I get the results (divs) to appear in the order Fruits, Vegetables, Meats, Nuts? At the moment they appear in the order that they are listed in the box. I would also like to ask if it is possible to keep the results (divs) showing for all the items selected even after a new search is performed and a new selection made. For example, if I search for 'F' and select 'Fruits' and then search for 'V' and select 'Vegetables', can I have both the 'Vegetables' and 'Fruits' divs showing in the results? At the moment, 'Vegetables' replaces 'Fruits'. If this is possible, would it also be possible to have the selected items in the list remain highlighted even after a new search is performed? For example, after making the above searches/selections, if I then search for 'ts', the list would show 'Fruits', 'Nuts' and 'Meats', but I would like 'Fruits' to still be highlighted and to be able to close the 'Fruits' div by de-selecting 'Fruits' from the list or clicking the Close (X) button on the 'Fruits' div itself. There are a few other things I have not been able to solve but I will refrain from posting too many questions at once. Any help would be greatly appreciated! Thank you.

    I use the W3C validator religously but is there a bug in it? When I check my code it displays a "duplicate id" error. However, a duplicate id is required to connect the audio tag and javascript. I've uploaded the validator screen capture and a portion of my offending HTML5 and javascript code. Thoughts anyone... SLiM
  18. Hi Guys, I have a table that shows information and the status of that, being on or off. the on and off part is hard to notice and as it is the most valuable I was hoping to change it from simple text of on/off to a green/red circle. At the moment I am using a text input in a form for on/off. I have looked around and haven't found much related to this. I am having to replace the text input box with the radio button and if its clicked it will show green and if not it will show red. any suggestions on this? I will attach my code below: input form: <th>Repo Status: * <td><input type="text" name="status" value="<?php echo $status; ?>" /></td></tr> Displayed Table: echo '<td>' . $row['status'] .'</td>'; Thanks in advance

  20. I am using the W3Schools CSS/JS modal dialog example: https://www.w3schools.com/howto/howto_css_modals.asp However I would like to be able to pass a parameter from the button to the modal window as a variable so I can use it to perform a database query and populate the modal. I HAVE looked through this site and others and can't find a straight forward way to do this. My code: The button: <button onclick='myModal($somevariable)'>Show modal</button> The click function: function myModal(myParams) { modal.style.display = "block" } The modal: var modal = document.getElementById('myModal'); The HTML on the webpage: <!-- The Modal --> <div id="myModal" class="modal"> <!-- Modal content --> <div class="modal-content"> <div class="modal-header"> <span class="close">×</span> <h2>Shot Plot</h2> </div> <div class="modal-body"> <p>Some stuff in the Modal Body using the myParams variable??</p> <p>Some other text...</p> </div> <div class="modal-footer"> <h3>footer</h3> </div> </div> </div> Any help appreciated, Lance
  21. I'm looking for a way to display the contents of an XML file on a web page with AJAX. I rely on the w3schools "simple CD catalog application", which shows a part of the XML (author and title) and, when you click on a title, displays the details of the CD. I need, however, to be able to add sorting and filtering when displaying artist and title - it could, for instance, be sorting the titles alphabetically or apply a filter based on the year of release. XSLT doesn't seem to work with AJAX so I hope JavaScript could be the answer: Is it possible to add such functions to the application example using JavaScript - and how could it be done? I'd really be glad if someone could help.

  23. I'm trying to develop a simple theatre seat reservation system. I'm using a text file "seats.txt", where I store seat number and status (f, r, s) and read the file line by line. If the user clicks on an image the javascript function is triggered and the image will change: <?php $counter = 0; $file = 'seats.txt'; $line = file($file); for($i=0;$i < 14;$i++){ $counter = $counter + 1; $string = $line[$i]; if($counter == 8) { echo "&nbsp &nbsp <img src='R1.bmp' /> &nbsp &nbsp &nbsp &nbsp"; } if(substr($string,4,1) == "f") { echo "<img id=$i onclick='myFunction(id)' src='chkBox_10.bmp' title='0' /> &nbsp &nbsp"; } else if(substr($string,4,1) == "s") { echo "<img id=$i onclick='myFunction(id)' src='chkBox_2.bmp' title='2' /> &nbsp &nbsp"; } else if(substr($string,4,1) == "r") { echo "<img id=$i onclick='myFunction(id)' src='chkBox_1.bmp' title='1' /> &nbsp &nbsp"; } else { echo "<img id=$i onclick='myFunction(id)' src='chkBox_3.bmp' title='3' /> &nbsp &nbsp"; } } ?> <script> function myFunction(imgID) { var img = document.getElementById(imgID).title; if (img == "1") { window.alert("Reserved seat!"); } else if (img == "2") { window.alert("Sold seat!"); } else if (img == "3") { window.alert("Handicap seat!"); } else if (img == "4") { document.getElementById(imgID).src = "chkBox_10.bmp"; document.getElementById(imgID).title = "0"; } else { document.getElementById(imgID).src = "chkBox_4.bmp"; document.getElementById(imgID).title = "4"; } } </script> My question is now: How can I get the selected seats (from the client side javascript) into a shopping cart (eventually on another page)?
  24. Hi guys, I have a table with a delete column with deletes individual rows from the column, I am looking to add a delete warning. Now I know you can add a javascript function but im unsure how to do this as my page is built in PHP. Here is the delete column: echo '<td data-sort-initial="Descending"><a href="delete.php?id=' . $row['id'] . '">Delete</a></td>'; Here is my delete.php file: <?php /* DELETE.PHP Deletes a specific entry from the 'players' table */ // connect to the database include('connect-db.php'); // check if the 'id' variable is set in URL, and check that it is valid if (isset($_GET['id']) && is_numeric($_GET['id'])) { // get id value $id = $_GET['id']; // delete the entry $result = mysql_query("DELETE FROM players WHERE id=$id") or die(mysql_error()); // redirect back to the view page header("Location: view.php"); } else // if id isn't set, or isn't valid, redirect back to view page { header("Location: view.php"); } ?> Thanks in advance
