  • jQuery - How can I temporarily disable the onclick event listener after the event has been fired?

    - by aldux
    How can I temporarily disable the onclick event listener, (jQuery preferred), after the event has been fired? Example: After the user clicks on the button and fires this function below, I want to disabled the onclick listener, therefore not firing the same command to my django view. $(".btnRemove").click(function(){ $(this).attr("src", "/url/to/ajax-loader.gif"); $.ajax({ type: "GET", url: "/url/to/django/view/to/remove/item/" + this.id, dataType: "json", success: function(returned_data){ $.each(returned_data, function(i, item){ // do stuff }); } }); Thanks a lot, Aldo

  • Jquery show preloader for every image?

    - by mathiregister
    Hey guys, I've a website with a lot of images: <img class='thumb' src=thumbs/image1.jpg/> <img class='thumb' src=thumbs/image2.jpg/> <img class='thumb' src=thumbs/image3.jpg/> <img class='thumb' src=thumbs/image4.jpg/> I wonder if I can display a loading-div for every single image and when it's loaded the div hides? I'm using jquery for most of my animations. Can i solve that with jquery. It would be cool if every image shows this loading-div centered in the middle of the image. When the image is loaded the div should hide! Is that possible? Thank you for your help!

  • How to read from CSS files with jQuery

    - by Neurofluxation
    Ok, I have a HTML page with jQuery included. I have a CSS file with a good load of lines in, I would like to read all styles for a given element from the external CSS file... Not the inline styles... I have the following code (which looks like it should work...): var styleProperties= {}; var getCssProperties = ['width', 'margin', 'height']; for (c=0;i<=returnStyleProps.length;c++) { styleProperties[returnStyleProps[c]] = $('div#container').css(returnStyleProps[c]); alert(styleProperties); } alert(styleProperties); But this only seems to alert: "[Object Object]" Any ideas you clever people?

  • preventing window blur/focusOut when selecting copy/paste menu

    - by jedierikb
    I am trying to determine when the user has moved focus out of the browser to: select copy/paste (but not to the google search box). Ffox handles this nicely. selecting another window/tab/external widget (e.g., the google search box). focusOut and blur listeners on window and document cannot seem to disambiguate between these two types of focus changes. Can IE do this? I want this distinction so that I can better support usability in my web app without losing focus.

  • jQuery featured content slider

    - by azz0r
    Hello, I have a content area that loops through divs and shows there content. I'm having trouble making it display the initial content, unfortunately it waits 5000 milliseconds before triggering the very first content area to display. Anyone spot an easy way to make it display the initial area, then slide to the next area and do them at 5000 milliseconds. JS Model.FeatureBar = { current:0, items:{}, init: function init(options){ var me = this; me.triggers = [] me.slides = [] this.container = jQuery('#features'); jQuery('.feature').each(function(i){ me.triggers[i] = {url: jQuery(this).children('.feature-title a').href, title: jQuery(this).children('.feature-title'),description:jQuery(this).children('.feature-description')} me.slides[i] = {image: jQuery(this).children('.feature-image')} }); for(var i in this.slides){ this.slides[i].image.hide(); this.triggers[i].description.hide(); } setInterval(function(){Model.FeatureBar.next()},5000); }, next: function next(){ var i = (this.current+1 < this.triggers.length) ? this.current+1 : 0; this.goToItem(i); }, previous: function previous(){ var i = (this.current-1 > 1) ? this.current-1 : this.triggers.length; this.goToItem(i); }, goToItem: function goToItem(i){ if(!this.slides[i]) throw 'Slide out of range'; this.triggers[this.current].description.slideUp(); this.triggers[i].description.slideDown(); this.slides[this.current].image.hide(); this.slides[i].image.show(); this.current = i; }, } html <div id="features"> <div class="feature current"> <div class="movie-cover"> <a href="/police/movie"><img title="" alt="" src="/design/images/four-oh-four.png"></a> </div> <div class="feature-image" style="display: none;"> <img src="/design/images/four-oh-four.png"> </div> <h2 class="feature-title"><a href="/police/movie">Police</a></h2> <p class="feature-description" style="overflow: hidden; display: block; height: 50.8604px; margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;">DESCRIPTION</p> </div> <div class="feature"> <div class="movie-cover"> <a href="/rude/movie"><img title="" alt="" src="/design/images/four-oh-four.png"></a> </div> <div class="feature-image" style="display: none;"> <img src="/design/images/four-oh-four.png"> </div> <h2 class="feature-title"><a href="/rude/movie">Rude</a></h2> <p class="feature-description" style="overflow: hidden; display: block; height: 18.3475px; margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;">DESCRIPTION</p> </div> <div class="feature"> <div class="movie-cover"> <a href="/brits/movie"><img title="" alt="" src="/design/images/four-oh-four.png"></a> </div> <div class="feature-image" style="display: block;"> <img src="/design/images/four-oh-four.png"> </div> <h2 class="feature-title"><a href="/brits/movie">Brits</a></h2> <p class="feature-description" style="overflow: hidden; display: block; height: 40.1549px; margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;">DESCRIPTION</p> </div> <div class="feature"> <div class="movie-cover"> <a href="/indie/movie"><img title="" alt="" src="/design/images/four-oh-four.png"></a> </div> <div class="feature-image" style="display: none;"> <img src="/design/images/four-oh-four.png"> </div> <h2 class="feature-title"><a href="/indie/movie">Indie</a></h2> <p class="feature-description" style="overflow: hidden; display: block; height: 42.4247px; margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;">DESCRIPTION</p> </div>

  • How can I stop a default event when using a named function in addEvent?

    - by Rupert
    Normally, if I wish to stop a default event in mootools I can do this: $('form').addEvent('submit', function(e) { e.stop(); //Do stuff here } However, I don't like using an anonymous function in events because I often want to reuse the code. Lets say I have a validate function. I could do this: $('form').addEvent('submit', validate); which works fine until I want to stop the default event. validate obviously doesn't know what e is so I can't just do e.stop(). Also I've tried passing the event as a variable to validate but whenever I use a named function with parameters, the function gets called automatically on domready, rather than on the event firing. Even worse, an error is thrown when the event is fired: What am I doing wrong?

  • How to stop/override a Jquery TimeOut function?

    - by Tom
    Hi, I have a small jquery snippet that displays notification message at the top of the screen in response to user actions on a page. The notification is often displayed after Ajax actions with dynamic content inside it. For example: $("#mini-txt").html("Thank you!"); $("#mini").fadeIn("fast"); setTimeout(function() {$("#mini").animate({height: "hide", opacity: "hide"}, "medium");}, 3000); The notification works well, except when a user does two or more actions in rapid succession, in which case the TimeOut function will confuse itself and the second message appears to come inside the previous 3000 milliseconds. Is there a way to "kill" the previous notification if a new action is performed. I've got no problem with the actions/selectors, just the TimeOut function.... either stopping it or overriding it somehow. Or perhaps there's a better alternative for getting the message to linger on the screen for a few seconds before disappearing? Thank you.

  • CKEditor plugin: Hightlight selected text by hovering on a new item in the toolbar and selecting fro

    - by scottystang
    I'm new to the CKEditor and I'm trying to create a simple plugin. What I'm hoping to accomplish is to allow the user to highlight some text and then hover on a new item in the toolbar that drops down on mouse over a few different highlight color options for the text. For example, the user could highlight some text, hover on my new item and then select a highlight color. This will be similar to the 'BGColor' plugin except instead of opening a color palette to choose from, the user would select from a drop down of options similar to when you choose to change the font size you have a list of options such as '10', '11', '12', etc. Any help would be appreciated on how to pull this off. I was hoping to check out how 'BGColor' and 'FontSize' plugins where implemented, but I can't find these in ../ckeditor/_source/plugins. Am I looking in the right spot? Also, the link for plugins here - http://docs.cksource.com/CKEditor_3.x/Developers_Guide isn't clickable so I'm not sure if there's a place for plugin documentation that I can check out.

  • how to redraw markers without redrawing the map? google maps.

    - by vishwanath
    I currently have a implementation where some markers coming from JSON list is shown, on a particular area, Now I want to filter these marker depending upon some criteria, I have done the filtering part, and got the filtered list. Now to render this markers on the map again, The current implementation loads the js with a key again, also creates the GMap2 object and draws the list of marker on the newly created map, which is really annoying. I want map to be there and only markers to be added and removed from the map. Any help is appreciated

  • How can I find the nearest intersection via the Google Maps API?

    - by dusoft
    How can I find the closest intersection of the street I have coordinates of? For instance, say I have street A running from south to north that is crossed by street X on the north and by street Y on the south. Does the Google Maps API allow for finding coordinates of the nearest crossroad (either X or Y) of street A? I couldn't find it mentioned anywhere. PS: The only solution I am aware of is to guess the lowest number and the highest number of building on the street A and to draw polyline between them. I am not sure about this though.

  • string auto splitting in each loop - jquery

    - by sluggerdog
    I have the following jquery code that is looping through the returned json data, for some reason is it splitting the suburb by a space when being assigned as the value but not as the text, I cannot work out why this is happening. MY CODE $.each(data , function( index, obj ) { $.each(obj, function( key, value ) { var suburb = $.trim(value['mcdl01']); var number = $.trim(value['mcmcu']); $("#FeedbackBranchName").append("<option value=" + suburb + ">" + suburb + " (" + number + ")</option>"); }); }); SAMPLE RETURNED RESULTS <option **value="AIRLIE" beach=""**>AIRLIE BEACH (4440)</option> <option value="ASHMORE">ASHMORE (4431)</option> <option **value="BANYO" commercial=""**>BANYO COMMERCIAL (4432)</option> <option value="BEENLEIGH">BEENLEIGH (4413)</option> <option value="BERRIMAH">BERRIMAH (4453)</option> <option **value="BOWEN" hills=""**>BOWEN HILLS (4433)</option> Notice how for AIRLEE BEACH, BANYO COMMERICAL AND BOWN HILLS the second word has been separated out from the value attribute but it's fine at the text level. Anyone have any idea why this might happen? Thanks

  • Refresh table after using jQuery .append()

    - by Aaron Salazar
    The following code gets a JSON object and then spits its contents out into a <table>. The first time I do it I get my JSON content just fine. However, when I refresh, the refreshed data is stuck onto the bottom of my table. How do I refresh the data to show the new data only? I tried using .remove() but there was an obvious deleting and then a refresh of data. $(function() { $('#ReportedIssue').change(function() { //$('.data').remove() $.getJSON('/CurReport/GetUpdatedTableResults', function(json) { for (var i = 0; i < json.GetDocumentResults.length; i++) { $('#DocumentInfoTable').append( "<tr class='data'>" + "<td>" + json.GetDocumentResults[i].Document.DocumentId + "</td>" + "<td>" + json.GetDocumentResults[i].Document.LanguageCode + "</td>" + "<td>" + json.GetDocumentResults[i].ReportedIssue + "</td>" + "<td>" + json.GetDocumentResults[i].PageNumber + "</td>" + "</tr>" ); }; }); }); }); Thank you, Aaron

  • Trigger the change event of a textbox in jQuery

    - by Danny Chen
    I have an asp:TextBox with asp:RegularExpressionValidator to validate if it's a number. Obviously an onchange event will be attached to this textbox while rendering. Also I add a change event at $(document).ready to make some calculation when the value is changed. <asp:TextBox id="myText" runat="server" /> <asp:regularexpressionvalidator id="myRev" ControlToValidate="myText" runat="server">*</asp:regularexpressionvalidator> $(document).ready(function(){ $('[id$=myText]').bind('change',function(){ //do something }).change(); //force the change event at the very beginning }); My function will be executed later than the .net generated js because of the register time. But the .net js throws an error. I traced in the js: function ValidatorOnChange(event) { ... } and found that all of event.fromElement,event.toElement,event.srcElement are null which causes the exception. Did I do something wrong? Any solutions? Thanks.

  • Highlight polygon and tint rest of map using Google Maps

    - by Haes
    Hi, I'd like to display a highlighted polygon using Google Maps. The idea is that the polygon in question would be displayed normally and the rest of the map should be darkened a little bit. Here's an example image what I would like to accomplish with a polygon from Austria: Unfortunately, I'm a complete rookie when it comes to Google Maps API's and map stuff in general. So, is this even possible do this with Google Map API's? If yes, with what version (v2, v3)? Would it be easier to do it with other map toolkits, like openlayers? PS: One idea I had, was to build an inverse polygon (in this example, the whole world minus the shape of austria) and then display a black colored overlay with transparency using this inverted polygon. But that seems to be quite complicated to me.

  • customisable JSLint

    - by Don
    Hi, I'm looking for a tool that checks JS code, which can be integrated into a Maven build. I need a tool that will check for errors such as use of reserved words as identifiers trailing semi-colon, e.g. var obj = { a: 1, b, 2, } JSLint seems like a perfect candidate, but the problem is that it is too strict, because it also checks for various coding patterns which are (arguably) bad style, but do not actually generate errors in a browser. Examples of such issues include Disallow ++ and -- and Allow one var statement per function If possible, I would like the errors to fail the build, and I would like the other rules to only print warnings (or disable them completely). Obviously, I need the ability to specify which of the available rules I consider errors and which I consider warnings. Thanks, Don

  • Connection Timeout Extension/Detection

    - by ircmaxell
    Well, let me start off by explaining what I'm trying to do. I have an application that stalls a HTTP connection until new data is available (sometimes a few seconds, sometimes 30 minutes or so). Right now, the system works fine if the data is sent within a few minutes. The problem I'm facing, is that it doesn't seem that XHR recognizes a dropped connection... So instead of killing the current connection and reconnecting when it detects a dropped connection, it just sits there. I'd really not like to have it force-reconnect every minute or two (That's one reason this app was written, to stop the need for polling). So, my questions are as follows: Is there a way to detect a dropped (not closed) TCP connection with XHR? Is there a way that I can tell XHR not to timeout (I saw IE8 has the .timeout property) Would it be better to send a header (or some other content) every now and then (say once per minute) down the pipe to keep the connection open? Thanks.

  • ASP.net canvas server control

    - by Pierreten
    I was wondering if anyone has come up with an ASP.net server tag for the HTML5 canvas? I was thinking of something where I could declaritively define paths, curves; etc in the aspx markup, and the control would deliver the js to do this (perhaps with support for browser detection, and delivery of an emulation script for IE browsers.) Maybe a good idea for a Codeplex project for me to start up?
