How to change class of textbox?

Question

my textbox has a class='cssText'. I want to change this class to 'blck' at runtime.

How can I access the class attribute of textbox and change its value using jQuery?

Thanks

Answer 1

$("input#id").removeClass("cssText").addClass("blck");

or

$("input#id").attr("class", "blck");

Answer 2

You shoudl select the textbox and then set the new class:

$(selector_for_textbox).removeClass('cssText').addClass('blck');

A possible selector for your textbox could ofcourse be the class, or otherwise an id or something:

$('#textbox'). //etc
$('input.cssText:text'). //etc

Edit from comments
You should use:

$('#txt').removeClass('cssText').addClass('blck');
