  • How to access a String that is in JSON array format

    - by Sayem Ahmed
    I have an asp.net page which is returning a list of object as a json string to an ajax request. The string is as follows : [ {"Name":"Don","Age":23,"Description":"Tall man with no glasses"} ,{"Name":"Charlie","Age":24,"Description":"Short man with glasses"} ] I want to access each field individually, like the name of the person, his age, his description etc. How can I do that? I am using JQuery for client-side scripting.

  • Testing drag-and-drop with Watir

    - by Marcel J.
    I'm evaluating Watir right now. While Selenium has a dragAndDropToObject command (which seems to be broken) Watir seems not to have such a command. I couldn't find a script/tutorial with an example of how to test DnD with Watir. Did anybody try/succeed in testing drag-and-drop with Watir? Btw.: I am using jQuery for the DnD implementation.

  • Where should JavaScript be put?

    - by NessDan
    I've been doing a little JavaScript (well, more like jQuery) for a while now and one thing I've always been confused about is where I should put my scripts, in the <head> tag or in the <body> tag. If anyone could clarify this issue, that'd be great. An example of what should go where would be perfect.

  • login form using ajax, to submit without refreshing

    - by Brad
    I am using this tutorial to create a login form http://www.ryancoughlin.com/2008/11/04/use-jquery-to-submit-form/ It authenticates against w/ our ldap server. What I am having a problem with is the line success: function(){ $('form#submit').hide(function(){$('div.success').fadeIn();}); It runs success even though we don't even know if the username and password binded successfully. Is there a way to only run success if the username and password posted was binded successfully?

  • Is it better to have client (Javascript) processing HTML rather than C# processing HTML?

    - by Raja
    We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work? Any justification with respect to either ways will be helpful. Thanks.

  • Changing Opacity of All Elements but One Div

    - by waiwai933
    I'm trying to fade all elements on a webpage except for one div. I've been able to fade all the elements with the following jQuery: $('*').css('opacity', .3); However, it seems as if opacity is a property that inherits from parent elements, even if I explicitly set the opacity of the div to 1. I'm drawing a blank as to any solutions right now, so can I have some help here?

  • How to detect that an Html element is in View?

    - by Olaseni
    Using Jquery preferably, how do I detect if an element is within the viewable client area of a browser? I'm dynamically creating a menu from a dataset, and when the list grows too long, the height of the resulting menu causes part of it to fall below the browser bottom client area. How do I detect this and act accordingly?

  • Comparing two large sets of attributes

    - by andyashton
    Suppose you have a Django view that has two functions: The first function renders some XML using a XSLT stylesheet and produces a div with 1000 subelements like this: <div id="myText"> <p id="p1"><a class="note-p1" href="#" style="display:none" target="bot">?</a></strong>Lorem ipsum</p> <p id="p2"><a class="note-p2" href="#" style="display:none" target="bot">?</a></strong>Foo bar</p> <p id="p3"><a class="note-p3" href="#" style="display:none" target="bot">?</a></strong>Chocolate peanut butter</p> (etc for 1000 lines) <p id="p1000"><a class="note-p1000" href="#" style="display:none" target="bot">?</a></strong>Go Yankees!</p> </div> The second function renders another XML document using another stylesheet to produce a div like this: <div id="myNotes"> <p id="n1"><cite class="note-p1"><sup>1</sup><span>Trololo</span></cite></p> <p id="n2"><cite class="note-p1"><sup>2</sup><span>Trololo</span></cite></p> <p id="n3"><cite class="note-p2"><sup>3</sup><span>lololo</span></cite></p> (etc for n lines) <p id="n"><cite class="note-p885"><sup>n</sup><span>lololo</span></cite></p> </div> I need to see which elements in #myText have classes that match elements in #myNotes, and display them. I can do this using the following jQuery: $('#myText').find('a').each(function() { var $anchor = $(this); $('#myNotes').find('cite').each(function() { if($(this).attr('class') == $anchor.attr('class')) { $anchor.show(); }); }); However this is incredibly slow and inefficient for a large number of comparisons. What is the fastest/most efficient way to do this - is there a jQuery/js method that is reasonable for a large number of items? Or do I need to reengineer the Django code to do the work before passing it to the template?
