  • XMLHttpRequest inside an object: how to keep the reference to "this"

    - by Julien
    I make some Ajax calls from inside a javascript object.: myObject.prototye = { ajax: function() { this.foo = 1; var req = new XMLHttpRequest(); req.open('GET', url, true); req.onreadystatechange = function (aEvt) { if (req.readyState == 4) { if(req.status == 200) { alert(this.foo); // reference to this is lost } } } }; Inside the onreadystatechange function, this does not refer to the main object anymore, so I don't have access to this.foo. Ho can I keep the reference to the main object inside XMLHttpRequest events?

  • Using a bookmarklet to track a package

    - by user307558
    I'm trying to write a bookmarklet that tracks a package in the mail. First it checks to see if the tracking page is open, if not it opens it in a new tab, and then sets the value of the form to the tracking number. Finally, it submits the form. What I'm so far unable to do is set the value of the form in the case where the bookmarklet opens up a new tab. Here's what I have: javascript: (function(){ var trackingNumber = "/*tracking number*/"; var a = document.forms.trackingForm; if ('http://fedex.com/Tracking' == document.location) { trackingForm.trackNbrs.value = trackingNumber; document.forms.trackingForm.submit(); } else { window.open('http://fedex.com/Tracking'); this.window.onload = function(){ //This seems to be the problem trackingForm.trackNbrs.value = trackingNumber; onload(document.forms.trackingForm.submit()); } } })(); Any ideas?

  • How to get this.grandparent() functionality in Mootools?

    - by RyOnLife
    I have built a class in Mootools and extended it twice, such that there is a grandparent, parent, and child relationship: var SomeClass1 = new Class({ initialize: function() { // Code }, doSomething: function() { // Code } }); var SomeClass2 = new Class({ Extends: SomeClass1, initialize: function() { this.parent(); }, doSomething: function() { this.parent(); // Some code I don't want to run from Class3 } }); var SomeClass3 = new Class({ Extends: SomeClass2, initialize: function() { this.parent(); }, doSomething: function() { this.grandParent(); } }); From Class3, the child, I need call the doSomething() method from Class1, the grandparent, without executing any code in Class2#doSomething(), the parent. What I need is a grandParent() method to complement the Mootools parent(), but it appears that one does not exist. What's the best way to accomplish this in either Mootools or pure JavaScript? Thanks.

  • How to make a link open in tabbed or new window without target attribute?

    - by Alan McCloud
    In my application an external website places link in my web page and the link does not have target=_blank. More specifically its iframe in my webpage whose src is another domain which I have no control. The content in this iframe contains links that opens in the same window wiping off my ajax driven web page and taking the user to the other domain. Is there a way to intercept this ( via javascript? ) and make the link open in another window or browser tab? It would be even much better if the link opens within the same iframe on my webpage. Is this possible? Is target="_self" makes the link open in the same iframe?

  • I want to query whitepages.com 4,000 times, how to save the results?

    - by John Corbin
    I have an old customer list of 4,000 businesses. I want to determine if the phone numbers associated with each listing are still working (and therefore the business is probably still open). I can put each number in whitepages.com and check them one by one... but want to automate the results. I have looked at their API and can't digest it. I can form the correct query URL, but trying things like cURL -O doesn't work. I have access to Mac tools, Unix tools, and could try various javascript stuff if anyone could point me in the right direction... would even pay. Help? Thx

  • Encode/compress sequence of repeating integers

    - by Alex
    Hey there! I have very long integer sequences that look like this (arbitrary length!): 0000000001110002220033333 Now I need some algorithm to convert this string into something compressed like a9b3a3c3a2d5 Which means "a 9 times, then b 3 times, then a 3 times" and so on, where "a" stands for 0, "b" for 1, "c" for 2 and "d" for 3. How would you do that? So far nothing suitable came to my mind, and I had no luck with google because I didn't really know what to search for. What is this kind of encoding / compression called? PS: I am going to do the encoding with PHP, and the decoding in JavaScript.

  • Typed Arrays in Gecko 2: Float32Array concatenation and expansion.

    - by janesconference
    Hi all, I'm a bit confused with Javascript Typed Arrays. What I have several *Float32Array*s, that have no concat method. I'd like to concatenate them all inside another Float32Array, but: as I said before, there is no concatenation method if I try to write past the array length, the array is not expanded (aka this won't work - please note that event.frameBuffer and buffer are both Float32Array and that I don't know what the final length of my buffer will be): var length_now = buffer.length; for (var i = 0; i < event.frameBuffer.length; i += 1) { buffer [length_now + i] = event.frameBuffer[i]; } The only solution I found is to copy the Float32Array in a regular array, that's definitely not what I want. How would you do, stackoverflowers?

  • onclick event not working after ie7 reload

    - by Charles
    I am using Javascript to dynamically create part of my page content. A routine that generates a set of img tags is called from the window.onload event. Those img tags are assigned attributes, including an onclick event. The img tags host thumbnail images that, when clicked, change the src property of the image in the main view div. Everything works properly in FF 3.5. I can reload the page and the dynamically generated onclick events continue to fire as expected. In IE7 everything works normally until I reload the page. At that point events that were hard coded into the xhtml section continue to work as expected, and the dynamically generated img tags are shown on the page, but their onclick events fail to work. How can I get IE7 to implement the dynamically generated click events on reload?

  • How to lock non-browser clients from submitting a request?

    - by Thomas Kohl
    I want to block non-browser clients from accessing certain pages / successfully making a request. The website content is served to authenticated users. What happens is that our user gives his credentials to our website to 3rd party - it can be another website or a mobile application - that performs requests on his behalf. Say there is a form that the user fills out and sends a message. Can I protect this form so that the server processing the submission can tell whether the user has submitted it directly from the browser or not? I don't want to use CAPTCHA for usability reasons. Can I do it with some javascript?

  • jQuery and ASP.NET drop down problem

    - by Sayem Ahmed
    I have a drop down in an ASP.NET page. Whenever the value of the drop down changes an ASP.NET AJAX request is made to the server. I also attached a jQuery "change" event handler to that list to execute some code when the value is changed. So, probably two different event handlers are being attached to the same drop down, and it's causing some problems, i.e., sometimes wrong drop down values are sent to the server. I don't know why is this happening but I think attaching two different event handlers to a same drop down may be the reason. Can anyone tell me what is the problem here? If what I guessed is true, then is there any other way to execute some custom javascript code before asp.net AJAX request is sent ?

  • Test For CSS3 Radial Gradient Vendor Syntax

    - by Scott Christopherson
    I'm having an issue where I'm trying to update the background gradient of an element with JavaScript based on values I specify. I tried this route: elem.style.backgroundImage = '-webkit-gradient(radial, '+x+' '+y+', 0, '+x+' '+y+', 800, from(#ccc), to(#333)), -moz-radial-gradient('+x+'px '+y+'px, circle cover, #ccc 0, #333 100%)'; Since Webkit and Gecko have two different syntaxes for CSS3 gradients, I need to specify both. However, the above code doesn't work. It works if I only have just the Gecko syntax or just the Webkit syntax, not both. I think you can check for CSS gradient support, but my question is, is there a way to check which syntax needs to be used without browser sniffing? Keep in mind that I need to set my gradients this way since the x and y coordinates of the gradient change dynamically. Hope this makes sense, thanks.

  • addEventListener gone after appending innerHTML

    - by Vishal Shah
    Okay, so i have the following html added to a site using javascript/greasemonkey. (just sample) *a id='abc'*HEllo*/a* *a id='xyz'*Hello*/a* (excuse me, i've had to replace the '<' '' with * since hyperlinks for new users aren't allowed!) and i've also added a click event listener for the elements. All works fine up to this point, the click event gets fired when i click the element. But... i have another function in the script, which upon a certain condition, modifies that html, ie it appends it, so it looks like: *a id='abc'*HEllo*/a* *a id='xyz'*Hello*/a* *a id='123'*Hello*/a* but when this is done, it breaks the listeners i added for the first two elements... nothing happens when i click them. if i comment out the call to the function which does the appending, it all starts working again! help please...

  • Combining javascripts into a single file

    - by toomanyairmiles
    Having read up recently on yahoo's web optimisation tips and using YSlow I've implemented a few of their ideas on one of my sites http://www.gwynfryncottages.com you can see the file here http://www.gwynfryncottages.com/js/gw-custom.js. While this technique seems to work perfectly on most occasions, and really does speed up the site, I do notice a significantly higher number of errors where the javascripts don't load or don't load completely while I'm working on the site so three questions:- is combining scripts this way a good idea at all in terms of reliablity? is there any way to measure the number of errors? is there any way to 'pre-load' the javascript or ensure that the number of loading errors is reduced?

  • Selecting a radio button when a dropdown value changes

    - by Tim F.
    My setup is something like this: radiobutton1 - selection1 radiobutton2 - selection2 textinput1 I want radiobutton1 to be selected whenever selection1 is changed, and I want radiobutton2 to be selected whenever either selection2 or textinput1 is changed. There has to be a simple javascript solution here... I just can't find it. Here's my actual code ("$semopt" is a string holding the html code for the options on the first selection input): <input type='radio' name='semester' value='existing'/>Existing semester: <select name='sem_id'">$semopt </select><br/> <input type='radio' name='semester' value='new'/>New Semester: <select name='sem_name'"> <option value='Fall'>Fall</option> <option value='Spring'>Spring</option> </select> <input name='sem_year' value='$thisyear' size='5'"/><br/>

  • Problem with jQuery and ASP.Net MVC 2

    - by robert_d
    I have a problem with jQuery, here is how my web app works Search.aspx web page which contains a form and jQuery script posts data to Search() action in Home controller after user clicks button1 button. Search.aspx: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<GLSChecker.Models.WebGLSQuery>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Title </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Search</h2> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm()) {%> <fieldset> <div class="editor-label"> <%: Html.LabelFor(model => model.Url) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Url, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Url) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Location) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Location, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Location) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.KeywordLines) %> </div> <div class="editor-field"> <%: Html.TextAreaFor(model => model.KeywordLines, 10, 60, null)%> <%: Html.ValidationMessageFor(model => model.KeywordLines)%> </div> <p> <input id ="button1" type="submit" value="Search" /> </p> </fieldset> <% } %> <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> jQuery("#button1").click(function (e) { window.setInterval(refreshResult, 5000); }); function refreshResult() { jQuery("#divResult").load("/Home/Refresh"); } </script> <div id="divResult"> </div> </asp:Content> [HttpPost] public ActionResult Search(WebGLSQuery queryToCreate) { if (!ModelState.IsValid) return View("Search"); queryToCreate.Remote_Address = HttpContext.Request.ServerVariables["REMOTE_ADDR"]; Session["Result"] = null; SearchKeywordLines(queryToCreate); Thread.Sleep(15000); return View("Search"); }//Search() After button1 button is clicked the above script from Search.aspx web page runs. Search() action in controller runs for longer period of time. I simulate this in testing by putting Thread.Sleep(15000); in Search()action. 5 sec. after Submit button was pressed, the above jQuery script calls Refresh() action in Home controller. public ActionResult Refresh() { ViewData["Result"] = DateTime.Now; return PartialView(); } Refresh() renders this partial <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" % <%= ViewData["Result"] % The problem is that in Internet Explorer 8 there is only one request to /Home/Refresh; in Firefox 3.6.3 all requests to /Home/Refresh are made but nothing is displayed on the web page. Another problem with Firefox is that requests to /Home/Refresh are made every second not every 5 seconds. I noticed that after I clear Firefox cache the script works well first time button1 is pressed, but after that it doesn't work. I would be grateful for helpful suggestions.

  • In an ASP.NET MVC site, where would the JQuery code go?

    - by Maxim Z.
    I'm just getting started with ASP.NET MVC. I'm going to be using JQuery on the website I'm making, but I'm not really sure about one thing: where would JQuery code be placed? This concerns two things: Where do I import the JQuery JavaScript file? (I've been thinking that the Master page would be a good place to do this; am I right, or do I have to import it in each view?) Should all my JQuery code be referenced from the Master page (i.e., I store my code that uses JQuery in a separate .js file and reference it in a <script> tag)? Thanks in advance.

  • Switching/Linking to another external stylesheet in a .js file using Ruby on Rails

    - by Jake
    Im learning JQuery from a Sitepoint Book but Im trying to apply all the lessons to a Rails App. In one lesson, we are taught how to switch to a different stylesheet if the browser window is resized beyond a certain point. Here's the javascript code: if ($('body').width() > 900) { $('<link rel="stylesheet" href="wide.css" type="text/css" />') .appendTo('head'); } else { $('link[href=wide.css]').remove(); } Rails doesn't seem to want to link to the new stylesheet using 'link rel'. I've tried using the Rails helper: <%= stylesheet_link_tag 'base', :media => 'screen' %> but that doesn't work in a .js file. How do I link to an external stylesheet in a .js file using Ruby? Can I use Ruby on Rails code in a .js file? Thanks.

  • How to override HTML <FONT SIZE="2"> with CSS

    - by Deverill
    I was given the task of doing a facelift to our current site. I am moderately well versed in CSS so I am converting the bazillion tags to CSS styles and deleting about 2 times that many that were simply not necessary. It's all going well until I run into a certain product page that is only a wrapper into which other HTML files are pulled by a server.execute(filename) command. (we're using aspx for the wrapper page.) There are almost 700 of these pages and they all are cursed with this and that. Past editors with FrontPage that only know how to drag pretty things on the screen. Anyway, I am wondering if there is a way to use CSS in the wrapper page to override the tag behavior so I can make it something sane that fits with the rest of my pages. I'd even be open to something JavaScript that would remove the tags, but that's my less preferred solution. Thanks!

  • Ouput all the page's media queries in a list

    - by alecrust
    Using JavaScript, what would be the best way to output a list containing all media queries that are being applied to the current page. I assume this would need to filtering to find embedded media queries i.e. <link rel="stylesheet" media="only screen and (min-width: 30em)" href="/css/30em.css"> as well as media queries located in CSS files, i.e. @media only screen and (min-width: 320px) {} An example output of what I'm looking for: <p>There are 3 media queries loaded on this page</p> <ol> <li>30em</li> <li>40em</li> <li>960px</li> </ol>

  • browser back acts on nested iframe before the page itself - is there a way to avoid it??

    - by kfiroo
    hi, i have a page with dynamic data loaded by some ajax and lots of javascript. the page contains a list from which the user can choose and each selected value loads new data to the page. one of these data items is a url provided to an iframe. i use jQuery BBQ: Back Button & Query Library to simulate the browser-back behavior. all works well besides the fact that when i click the back button for the first time the iframe goes back to its previous location and then i need to click back again to make the page go back. is there a way to disable the iframe's back behavior?

  • Detecting if a browser is using Private Browsing mode

    - by Steve
    I'm building an extranet for a company paranoid about security. They want to make sure that (among other things) their users are browsing the site with the Private Browsing mode switched on in their web browser so that no cookies or history is kept. I found only this http://jeremiahgrossman.blogspot.com/2009/03/detecting-private-browsing-mode.html and http://serverfault.com/questions/18966/force-safari-to-operate-in-private-mode-and-detect-that-state-from-a-webserver The ideal solution would use no or minimal javascript. Would attempting to set a unique cookie work for all browsers and platforms? Anyone done this before? thanks!

  • URL encoding for document.location.href

    - by Tyler
    Hello - I am building an iFrame and am using document.location.href - my exact code is: <script type="text/javascript"> document.write("<iframe src='http://www.facebook.com/plugins/like.php?href=" + document.location.href + "&layout=standard&show_faces=false&action=like&font=verdana&colorscheme=light' frameborder=0></iframe>"); </script> This is working great for all of my pages except one. I believe the issue with the one page is caused by a dash "-" being in the page name. My questions is - is there a way to encode my src differently so that the link works? The CORRECT URL I want it to pull is: []/products/Product%252dExample.html But what it IS pulling in is: []/products/Product-Example.html And this is causing the page to not work correctly. Thanks!
