  • how to view associated click function code

    - by llamerr
    For example, i associate following function with some element $('table#users tbody tr:first #save').click(function(){ $(this).closest('tr').remove(); }); Now, if i don't know where this function is stored, is there a way to view associated with click() code? In above example, i want a way to view that in firebug, or in another way $(this).closest('tr').remove(); If I'm writing in console following, i'm get a link to dom inspector >>> ($('table#users tbody tr:first #save').click) function() but link is for jquery library, not the code i want.

  • Sequencing ajax requests

    - by Scott Evernden
    I find I sometimes need to iterate some collection and make an ajax call for each element. I want each call to return before moving to the next element so that I don't blast the server with requests - which often leads to other issues. And I don't want to set async to false and freeze the browser. Usually this involves setting up some kind of iterator context that i step thru upon each success callback. I think there must be a cleaner simpler way? Does anyone have a clever design pattern for how to neatly work thru a collection making ajax calls for each item?

  • Map works, but throws a popup error at load complainig about wrong api key

    - by Filip
    Ok, I see a lot of people have this problem, but none answer I found either here or at stackoverflow. Problem: Map works super fine! But throws an error at load "This map needs a different api key... sign up at......" Already signed up, already got a key. On some forum post a guy told that in this case map loads twice, once with the wrong key, another with the right one. But Im sure my app loads it once and with the correct key. URL: http://ki.org.ua/ (it will redirect to /projects but I think that it aint a problem cuz i tested without redirection too) Thanks in advance for any suggestion or help.

  • Print specific part of webpage

    - by Grega Menih
    I'm trying to print a specific part of my application. The application has a list of users, displaying their first and last name. When I click a user I get a popup with more detailed information about them. How would I go about printing just the popup for a user I clicked? The popup looks like this: <div id="user<?=$user->id;?>" class="popup"> <div class="details"> User details... </div> <a href="#print">Print</a> </div> The print button isn't working yet though.

  • how to handle large dataset like sproutcore

    - by Nik
    Hello all, I really don't have any substantial code to show here, actually, that's kinda why I am writing: I looked at the SproutCore demo, especially the Collection demo, on http://demo.sproutcore.com/sample_controls/, and am amazed by its loading 200,000 records to the page so easily. I tried using Rails to provide 200,000 records and in a completely blank HTML page with <% @projects.each do |p| % <%= p.title % <% end % that freezes the browser for seconds on my m1530 laptop with 4gb ram and t7700 256gb ssd. Yet the sproutcore demo does not freeze and takes less than 3 seconds to load. What do you think the one technique they are using to enable this is? Thanks!

  • Get Caret Position within an Text Input field

    - by MarkB29
    How could can I get the caret position from within an input field. I have seen a few bits and pieces on google but nothing bullet proof. Basically something like a Jquery plugin would be ideal so I could simply do $("#myinput").caretPosition() I realise there may by other non-jQuery solutions and these would also be brilliant if anyone has any??

  • jQuery plugin design pattern for using `this` in private methods?

    - by thebossman
    I'm creating jQuery plugins using the pattern from the Plugins Authoring page: (function($) { $.fn.myPlugin = function(settings) { var config = {'foo': 'bar'}; if (settings) $.extend(config, settings); this.each(function() { // element-specific code here }); return this; }; })(jQuery); My code calls for several private methods that manipulate this. I am calling these private methods using the apply(this, arguments) pattern. Is there a way of designing my plugin such that I don't have to call apply to pass this from method to method? My modified plugin code looks roughly like this: (function($) { $.fn.myPlugin = function(settings) { var config = {'foo': 'bar'}; if (settings) $.extend(config, settings); this.each(function() { method1.apply(this); }); return this; }; function method1() { // do stuff with $(this) method2.apply(this); } function method2() { // do stuff with $(this), etc... } })(jQuery);

  • can not find out if the div element is already set in body in chrome extension

    - by alpham8
    in my chrome extension I got an div, which I will add to the body of the current tab. I am listening to chrome.tabs.onUpdated. If this event is called, I execute a script inside content_scripts. In this function there I´ll wait till the document is ready with jQuery $(document).ready(...). I try to access $("#div").length and sometimes it returns 1 and sometimes 0. It should added to the body, if it´s not already there. For some strange reasons, the onUpdated event is called twice on each page reload. Actually I found no way to check safely if the div was already added.

  • How do I automatically update hundreds of images in an HTML page using jquery?

    - by Chris
    I have an HTML page where I want to refresh a lot of images every 30 seconds after the HTML page has been downloaded. I understand how to do this with Jquery and a single image, but I want to use about 200 custom urls to determine the current image to display for over 200 images. I need to find an efficient way to have jquery call the custom url associated with each image to download the url for the needed image as it changes, and then update the image in the page when it changes. Current hyperlink example to demonstrate the custom urls. <A href="/urlThatReturnsCurrentImageURL/1234/4567">link to url for image</A> Each custom url will return an image tag like this (or any other text that makes this simpler for jquery) <img src="/static/someImage.jpg"> What is the simplest way to have jquery call the custom url for each image to download the image url, image html, or some other text that jquery can use to download the right image every 30 seconds? Please keep in mind that I will have about 200 of these on a page.

  • Finding out inside which iframe a script is executing

    - by juandopazo
    I have a page with several iframes. One of this iframes has a page from a different domain. Inside this iframe there's another iframe with a page from the parent domain. my page from mydomain.com -> an iframe -> iframe "#foo" from another-domain.com> -> iframe "#bar" from mydomain.com -> another iframe I need to get a reference to the "#foo" node inside the main page. The security model should allow me to do that because "#bar" has the same domain as the main page. So what I'm doing is iterating through the window.top array and comparing each element to the window object which is currently the "#bar" window object. My test code looks like: for (var i = 0; i < top.length; i++) { for (var j = 0; j < top[i].length; j++) { if (top[i][j] == window) { alert("The iframe number " + i + " contains me"); } } } This works fine in all browsers, but Internet Explorer 6 throws a security error when accesing top[i][j]. Any ideas on how to solve this on IE6? Thanks!

  • Tabs.url is undefined

    - by Notionwork
    I have no clue what I'm doing wrong here! This should be working I believe. I'm writing a chrome extension and this should get the current tab's url and set the html of #current-tab to the url (for testing purposes). The code successfully gets to the callback, but it says that tab.url is undefined when I put it in an alert box, and it does not put it's value in #current-tab. Here's the code I have: $('#get-tab').click(function(){ chrome.tabs.query({"active" : true}, function(tab){ for (var i = 0; i < tab.length; i++) { alert(tab.url); $('#current-tab').append(tab.url); }; }); });

  • Selecting the correct input field using jquery

    - by rshivers
    I'm trying to select the id's of dynamic input fields in my code. When clicking a button, the form will create a form field like this: <td><input type="text" id="field_a_1"></td> <td><input type="text" id="field_b_1"></td> <td><input type="text" id="field_c_1"></td> When I click on the button again I get this: <td><input type="text" id="field_a_2"></td> <td><input type="text" id="field_b_2"></td> <td><input type="text" id="field_c_2"></td> What I want to do is select only the field id that I need to pull the value from that particular input and pass it to a variable like this: var example = $(":input:eq(0)").val(); I know that by adding the :eq(0) after the :input selector it will only grab the id for field_a_1, so how do I set it up so that I can pull just the field that I need to assign it to a variable?

  • jQuery: Freezing/Disabling all events temporarily?

    - by Legend
    I have the following usecase: A div with some buttons When the user clicks on a button, a popup is shown and the background div is faded out to 0.5 opacity The problem is that when the popup comes in, the user is still able to click on the background buttons. At this point, I can remove the entire DIV temporarily but I don't want to do that. Is there anyway I can disable all the previously attached events and then add event handlers ONLY to the current popup? (I mean something like a close button should still work on a popup) Any suggestions?

  • JSON Response {"d":"128.00"} but displaying "128"

    - by TGuimond
    Hi all, I have been working on a shopping cart that the user can add/remove order items as they please and am returning an updated sub-total via a webservice using jQuery $.ajax Here is how I am calling the webservice and setting the sub-total with the response. //perform the ajax call $.ajax({ url: p, data: '{' + s + '}', success: function(sTotal) { //order was updated: set span to new sub-total $("#cartRow" + orderID).find(".subTotal").text(sTotal); }, failure: function() { //if the orer was not saved //console.log('Error: Order not deleted'); } }); The response I am getting seems perfectly fine: {"d":"128.00"} When I display the total on the page it displays as 128 rather than 128.00 I am fully sure it is something very simple and silly but I am so deep into it now I need someone with a fresh brain to help me out!! Cheers :)

  • Calling multiple functions simultaneously with jquery.

    - by clarke78
    I want to loop through an object that contains functions which will execute one after another. My most ideal approach would be to have these chain somehow (ie. func2 waits for func1 and func3 waits for func2) but this needs to happen dynamically and the functions will all have different durations. I'm using jQuery so I thought that perhaps "queue()" may help but I haven't worked with it much. A main concern is to not add any scope/callbacks to the functions within the object. I'd rather somehow enclose them within a parent function to execute within the loop in order to create the callback/chaining. Here's an example of what I've got now, but dumbed down. Thanks for any help! var obj = [ {'name':'func1','callback':function(){ alert(1); }}, {'name':'func2','callback':function(){ alert(2); }}, {'name':'func3','callback':function(){ alert(3); }} ]; $.each(obj, function(x, el) { el.callback(); });
