  • Is this correct about ajax POST?

    - by Tommy
    Could you confirm I understand this correctly. Using POST, the file specified in xmlhttp.open("GET","ajax_test.asp",true); will not be cached (sent to \Temporary Internet Files) ? It will stay on the server only? If this is true, is the updated html file after calling ajax POST, being updated in the \Temporary Internet Files ? Am I missing any other important information of this mechanism? Thank You.

  • Firefox running infinitely even after condition met in jquery function

    - by Kyle
    The following function is called with setTimeout(function () { get_progress(fileID,fileName)},8000); upon a form submit. The purpose of the function is to get read_file.php to read a txt file that stores the file upload status from a form (in percentage). Upon reaching 80%, my Firefox seems to run infinitely even when HEAD returns an error. Am I have too many recursions or have I used a wrong condition that's causing get_progress to run repeatedly even when filename does not exist in the folder ? function get_progress( fileID, filename) { $.ajax({ url: filename, type: 'HEAD', success: function() { $.ajax({ type: 'POST', url: 'read_file.php', data: 'filename=' +filename, success: function(html) { document.getElementById(fileID).innerHTML = html + ' <img src="images/loading.gif" />' setInterval(function() {get_progress(fileID,filename)},4000); } }); } });}

  • Can I declare the same value for two attributes at once

    - by graphicdivine
    For example, for accessibility reasons I want my onfocus and onmouseover to have identical values. For the sake of maintainability I want to declare this once only. What I'd like to be able to do is this: <a onmouseover,onfocus="assist('hello');">linktext</a> But, of course, that would be too easy, and doesn't work. What's the best way I can achieve this DRYing out of my tags?

  • Coffeescript getting proper scope from callback method

    - by pandabrand
    I've searched for this and can't seem to find an successful answer, I'm using a jQuerey ajax call and I can't get the response out to the callback. Here's my coffeescript code: initialize: (@blog, @posts) -> _url = @blog.url _simpleName = _url.substr 7, _url.length _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128' $.ajax url: _avatarURL dataType: "jsonp" jsonp: "jsonp" (data, status) => handleData(data) handleData: (data) => console.log data @avatar = data Here's the compiled JS: Blog.prototype.initialize = function(blog, posts) { var _avatarURL, _simpleName, _url, _this = this; this.blog = blog; this.posts = posts; _url = this.blog.url; _simpleName = _url.substr(7, _url.length); _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128'; return $.ajax({ url: _avatarURL, dataType: "jsonp", jsonp: "jsonp" }, function(data, status) { return handleData(data); }); }; Blog.prototype.handleData = function(data) { console.log(data); return this.avatar = data; }; I've tried a dozen variations and I can't figure out how to write this? Thanks.

  • Hide Dynamically Added Columns/Fields

    - by baldwingrand
    I have some dynamically created rows/columns. What I'd like to do is set a section of it (txtOffsetID) to be hidden. I tried this: txtOffsetID.setAttribute('type', 'hidden'); but it didn't work. I want to hide that entire column and any new columns added. I need it to work in IE. Thanks. Sample code: function addNewOffsetItem() { var iX = document.getElementById("txtOffsetIndex").value; iX ++; document.getElementById("txtOffsetIndex").value = iX; var tbl = document.getElementById("tblOffsetDetail").getElementsByTagName("TBODY")[0]; var tr = document.createElement("TR"); tbl.appendChild(tr); //This section should be hidden. //txtOffsetID1 var tdID = document.createElement("TD"); tr.appendChild(tdID); var p = document.createElement("P"); tdID.appendChild(p); var txtOffsetID = document.createElement("input"); p.appendChild(txtOffsetID); txtOffsetID.id = "txtOffsetID" + iX; txtOffsetID.setAttribute('name','txtOffsetID' + iX); //This section should be visible. //txtOffsetComments1 var tdComments = document.createElement("TD"); tr.appendChild(tdComments); var p = document.createElement("P"); tdComments.appendChild(p); var txtOffsetComments = document.createElement("textarea"); p.appendChild(txtOffsetComments); txtOffsetComments.id = "txtOffsetComments" + iX; txtOffsetComments.setAttribute('name','txtOffsetComments' + iX); }

  • jquery ajax calls with scope safety

    - by acidzombie24
    My gut tells me that if i am on a laggy server and the user fires two events fast enough on the success function c will be the value of the most recent event causing func1 to use the wrong value. <--- This is a guess, i haven't proved it. Its a feeling. How do i ensure that i use the right value when calling func1? I prefer not to send c to the server and i dont know if or how to serialize the data and deserialize it back. How do i make this code safe? $('.blah').click(function (event) { var c = $(this).closest('.comment'); ... $.ajax({ url: "/u", type: "POST", dataType: "json", data: { ... }, success: function (data) { func1(c. data.blah);//here

  • Question on Virtual Methods

    - by bobber205
    IF both methods are declared as virtual, shouldn't both instances of Method1() that are called be the derived class's Method1()? I am seeing BASE then DERIVED called each time.

  • travesersing the dom with inexact parameters

    - by rashcroft23
    Hi, I want to grab the image src on a product page in a e commerce website. I'm writing this as a bookmarklet, so I'd like the code to work universally as possible. I've noticed that there are only two reoccurring factors in the product image tag among top e-commerce websites (amazon, bestbuy ect.): border=0 and 180<width&height<400. So how could I write a selector that would give me the srcof the first img element on the page with no border and width & height between 180 and 400 px? Or is there a better way of doing this? P.S. since I'm trying to keep the bookmarklet as light as possible, I don't want to use any libraries (jquery, yui etc)

  • Reiterate over a jQuery plugin's this.each()

    - by eth0
    Hi, I'm making a plugin and one of the options is a standard callback. I want the user to be able to re-run the jQuery plugin's this.each() which basically re-runs the plugin, for example; callback: function(){ // some code to rerun the plugin here after 10 seconds } I know I can do this like so: $(this).plugin_name(); but it won't contain any of the options I've specified. Any help would be appreciated.

  • jQuery selector - style values

    - by kender
    I got a series of divs like this: <div class="message" style="padding-left: 0px;">...</div> <div class="message" style="padding-left: 20px;">...</div> <div class="message" style="padding-left: 20px;">...</div> <div class="message" style="padding-left: 40px;">...</div> <div class="message" style="padding-left: 20px;">...</div> And I would like to make a selector that would get me the divs with padding greater then 20px. Would it be possible with just using jquery? Or I should modify my html tree and add some attribute that would distinguish those elemenents with high padding value?
