  • jQuery.keypad Performance Issues

    - by John Duff
    I am working on a Kiosk Touch Screen application and using the JQuery.keypad plugin and noticing some major performance issues. If you click a number of buttons in rapid succession the CPU gets pegged, the button clicks don't keep up with the clicking and some button presses even get lost. On my dev machine this isn't as noticeable, but on the Kiosk itself with 1 gig of ram it's painful. Trying the demo keypad at http://keith-wood.name/keypad.html#inline the one with multiple targets (which is the case with mine) has the exact same issues. Does anyone have any suggestions on how we might be able to improve this? The Kiosk runs in Firefox only so something specific to that would work. I'm using v1.2.1 of jquery.keypad and just upgraded to v1.4.2 of jquery.

  • Post Loading ads from Google Admanager

    - by Prem
    I have changed code around to basically load an add the bottom of the page in a hidden div and attached an onload event handler that called document.getElementById(xxx).appendChild() to take the hidden ad and move it into the right spot in my page. This works GREAT.. however when the ad is a text ad it AFTER i move the ad there is nothing in the rendered Iframe. I did tests to see what it looks like before i move it and sure enough the text links load in the IFRAME but the second i do the appendChild call to move the div that contains the ad i seem to loose the contents of the Iframe. Any ideas whats going on <div id="myad" style="display: none;"> GA_googleFillSlot("MyADSlotName"); </div> <script> window.onload = function() { // leader board document.getElementById('adplaceholder').appendChild(document.getElementById('myAd')); document.getElementById('myAd').style.display = ''; </script

  • Bubble sort dropped images based on their names

    - by user2259784
    I have written a simple bubble sort function that sort an array of Image objects based on image names. For some reason my function is not swapping the elements of array when needed ( basically new assignment is not working) Here is my code : listOfFiles = event.dataTransfer.files; sortImages(listOfFiles); function sortImages(listOfFiles) { var re = /[0-9]/; var temp; for( var index=0; index < listOfFiles.length ; index++) { for ( var index2=0; index2 < listOfFiles.length-1 ; index2++) { var one = parseFloat(re.exec(listOfFiles[index2].name )); var two = parseFloat(re.exec(listOfFiles[index2+1].name)); console.log(one + " : " + two); if (one > two) { console.log(listOfFiles[index2+1]); console.log(listOfFiles[index2]); //following three lines don't work temp = listOfFiles[index2+1]; listOfFiles[index2+1] = listOfFiles[index2]; listOfFiles[index2] = temp; console.log(listOfFiles[index2+1]); console.log(listOfFiles[index2]); } } } }

  • Get all Select Elements in a Form by referencing $(this) instead of $("form select")

    - by DaveDev
    Hi Guys I'm currently getting all the Select elements that exist in a form with the following: $("form").submit(function(event) { // gather data var data = GetSelectData($("form select")); // do submit $.post($(this).attr("action"), data, ..etc) }); Instead of passing in $("form select"), is there a way I can say something like $(this).children('select') // this doesn't work, btw to get all the select elements that exist within the context of the form the submit event is executing for? This will allow me to reduce my code to the following, moving all the functionality into a common function: $("form").submit(function(event) { GatherDataAndSubmit($(this)); }); function GatherDataAndSubmit(obj) { var data = GetSelectData(obj.children('select')); $.post(obj.attr("action"), data, ..etc) } Thanks Dave

  • html5 uploader + jquery drag & drop: how to store file data with FormData?

    - by lauthiamkok
    I am making a html5 drag and drop uploader with jquery, below is my code so far, the problem is that I get an empty array without any data. Is this line incorrect to store the file data - fd.append('file', $thisfile);? $('#div').on( 'dragover', function(e) { e.preventDefault(); e.stopPropagation(); } ); $('#div').on( 'dragenter', function(e) { e.preventDefault(); e.stopPropagation(); } ); $('#div').on( 'drop', function(e){ if(e.originalEvent.dataTransfer){ if(e.originalEvent.dataTransfer.files.length) { e.preventDefault(); e.stopPropagation(); // The file list. var fileList = e.originalEvent.dataTransfer.files; //console.log(fileList); // Loop the ajax post. for (var i = 0; i < fileList.length; i++) { var $thisfile = fileList[i]; console.log($thisfile); // HTML5 form data object. var fd = new FormData(); //console.log(fd); fd.append('file', $thisfile); /* var file = {name: fileList[i].name, type: fileList[i].type, size:fileList[i].size}; $.each(file, function(key, value) { fd.append('file['+key+']', value); }) */ $.ajax({ url: "upload.php", type: "POST", data: fd, processData: false, contentType: false, success: function(response) { // .. do something }, error: function(jqXHR, textStatus, errorMessage) { console.log(errorMessage); // Optional } }); } /*UPLOAD FILES HERE*/ upload(e.originalEvent.dataTransfer.files); } } } ); function upload(files){ console.log('Upload '+files.length+' File(s).'); }; then if I use another method is that to make the file data into an array inside the jquery code, var file = {name: fileList[i].name, type: fileList[i].type, size:fileList[i].size}; $.each(file, function(key, value) { fd.append('file['+key+']', value); }); but where is the tmp_name data inside e.originalEvent.dataTransfer.files[i]? php, print_r($_POST); $uploaddir = './uploads/'; $file = $uploaddir . basename($_POST['file']['name']); if (move_uploaded_file($_POST['file']['tmp_name'], $file)) { echo "success"; } else { echo "error"; } as you can see that tmp_name is needed to upload the file via php... html, <div id="div">Drop here</div>

  • Detect click events outside div inside usercontrol

    - by toraan
    I have a div inside a user control that is displayed by the user after some event. I want to hide this div when user clicks anywhere elese on the page but not on the div (or not on any element that is inside the div). If it wasn't a user control I could use body's clieck event to check the target, but because this is usercontrol that is hosted by other page I can't just "play" with it's elements. How can I achieve that without using body of the hosting page?

  • Does IBM use Dojo Toolkit?

    - by Timothy
    I was told IBM no-longer uses Dojo. Is this true? A small amount of web searching shows IBM is/was a member of the Dojo Foundation and is/was a code contributor... If it is true, approximately when did IBM stop using Dojo? If its not, to what extend is IBM still actively using and promoting the toolkit (use in their public web sites, product integration/bundling, etc)?

  • W3 xHTML Validation Errors on jQuery code!

    - by Chris
    I have some jQuery code that, without it in the document it passes validation fine, but with it in it causes errors. The code in question is here: $.ajax({ type: "GET", url: "data.xml", dataType: "xml", success: function(xml) { //Update error info errors = $(xml).find("Errors").find("*").filter(function () { return $(this).children().length === 0; }); if (errors.length == 0) { statuscontent = "<img src='/web/resources/graphics/accept.png' alt='' /> System OK"; } else { statuscontent = "<img src='/web/resources/graphics/exclamation.png' alt='' /> "+errors.length+" System error"+(errors.length>1?"s":""); } $("#top-bar-systemstatus a").html(statuscontent); //Update timestamp $("#top-bar-timestamp").html($(xml).find("Timestamp").text()); //Update storename $("#top-bar-storename").html("Store: "+$(xml).find("StoreName").text()); } }); There are loads of other jQuery code on the page which all works fine and causes no errors so I cannot quite understand what is wrong with this. The page isn't "live" so cannot provide a link to it unfortunately. The error it lists is document type does not allow element "img" here And the line of code it points to is here: statuscontent = "<img src='/web/resources/graphics/accept.png' alt='' /> System OK"; It also has an issue with the next assignment to statuscontent

    I'm trying to update a graph with received data, so that the height of the bars increase as more data is received from the server via a websocket. But my code doesn't render a graph in the browser and plot the data points. I cannot see anything wrong with the code.

  • Speeding up jQuery empty() or replaceWith() Functions When Dealing with Large DOM Elements

    - by Levi Hackwith
    Let me start off by apologizing for not giving a code snippet. The project I'm working on is proprietary and I'm afraid I can't show exactly what I'm working on. However, I'll do my best to be descriptive. Here's a breakdown of what goes on in my application: User clicks a button Server retrieves a list of images in the form of a data-table Each row in the table contains 8 data-cells that in turn each contain one hyperlink Each request by the user can contain up to 50 rows (I can change this number if need be) That means the table contains upwards of 800 individual DOM elements My analysis shows that jQuery("#dataTable").empty() and jQuery("#dataTable).replaceWith(tableCloneObject) take up 97% of my overall processing time and take on average 4 - 6 seconds to complete. I'm looking for a way to speed up either of the above mentioned jQuery functions when dealing with massive DOM elements that need to be removed / replaced. I hope my explanation helps.

  • JS function returning another function

    - by Michael
    I want to understand about variables, that has been used in returning function. This is example code Prototype = {} Prototype.F = { bind: function() { var args = arguments, __method = args.shift(), object = args.shift(); return function() { return __method.apply(object, args.concat(arguments)); } } } function ObjectA() { ... this.addListener = Prototype.F.bind(this.eventSource.addListener, this.eventSource); ... } var a = ObjectA(); a.addListener(this); // assuming 'this' here will point to some window object As I understand the returning function in F() is not evaluated until it's called in the last line. It's ok to accept. So addListener will hold a function body containing 'apply'. But what I don't understand, when addListener is called, what kind of parameters it is going to have? particularly _method and args will always be uninitialized?

  • How to find scrollable elements in DOM using XPath?

    - by ak.
    Basically I need to find all elements on the page that have a scrollbar (vertical or horizontal) How to tell if an element has a scrollbar and can actually be scrolled? I found this code snippet on jsperf. Is it possible to capture the logic behind the code into and XPath expression? Or are there any other ways to check for scrollbars? Added: Just to explain what I'm trying to do: I'm developing extension for Firefox. Basically it introduces Vim-style mouseless shortcuts (I know there is Vimperator and Pentadactyl...). One of the features I'd like to implement is to allow the use to select the container that's scrolled with j/k keys. That's why I need to discover all scrollable elements on any given random page.

I know there are likely slight things that are going to be off, but this isn't working at all. Thanks in advance.

  • Filtering data in an array.

    - by user276424
    Hi all, I have an array that has 30 date objects. The date objects are indexed in the array from the minimum date value to the maximum date value. What I would like to do is retrieve only 7 dates from the array. Out of the 7, the first one should be the minDate and the last should be the maxDate, with 5 dates in the middle. The 7 numbers should increment evenly from the minDate to the maxDate. How would I accomplish this? Hope I was clear. Thanks, Tonih

  • How can I organize many results in a selectbox using php?

    - by zeckdude
    I have a select box that is part of a form. It is currently querying the addresses table and displaying the addresses into the select box. I plan on having up to 100 addresses. I'm looking for a solution where I can show all the states if the user clicks on the select box. Then if the user hovers over a state it will show all the addresses for that specific state. Then if the user clicks on an address, it will show that as the picked option in the select box. This is like a dropdown menu within a select box. Does anyone know where I can find a solution as this?
