jQuery Forum

         I am a novice and I have issue in firing an server side event from Jquery. Scenario: I have a textbox in user control which has a event TextChanged that I need to fire when the text box loses the focus, I am trying to do in blur event. See the below code, 

Jquery code: 

C# Server side code: 

How do I call the event in jquery? Please let me know if you require any other detials. Help

Note: Eventhough I set the Autopostback property to true on Textbox, the event does not fire appropriately, that is the reason I have gone for Jquery whenever it loses focus.

         I am just starting to learn jQuery on my own and I'm bit confused looking at the below code. The argument in the below code $("span", this).addClass("bar");, is 'this' context referring to document context or div.foo context. Will it only look for the span selector inside the div element with foo class???  

$( "div.foo" ).click(function() {
 $( "span", this ).addClass( "bar" );
});
