Add attributes to textbox using jquery

I am using asp.net MVC.

I have control like

<%= Html.TextBox("username") %>

I want lost focus event to that control.

So code like

$(document).ready(function() {
        $("#username").Attributes.Add("onblur", "alert('losing focus');");
    })

but it is not working,

Ultimate goal is to check password & confirm password matches

help me!

From stackoverflow

• It looks like you're trying to use C# code in jQuery?

  The easiest way to bind an event to onblur in jQuery is:

  $("#username").blur(function() { alert('losing focus'); });
  

  More information on blur() is available at http://docs.jquery.com/Events/blur

• I believe your jQuery syntax is wrong,

  You want to bind an event, "onBlur" that fires the alert, so try

  $("#username").blur(function(){ alert("loosing focus"); });

  -- update, looks like some one answered this as I was answering

• $(document).ready(function() {
      $("#username").blur(function() {
  alert('byebye focus');
  
  })
  })

  Maksim Kondratyuk : Yeah, this good solution too. Very useful link is http://visualjquery.com/

• You can try attach to this event with another way, like this:

  $("#username").bind("blur", function(e){
    alert('hello');
  });
