查找文本框是否禁用或不使用 jquery

.prop('disabled') will return a Boolean:

var isDisabled = $('textbox').prop('disabled');

Here's the fiddle: http://jsfiddle.net/unhjM/

You can use $(":disabled") to select all disabled items in the current context.

To determine whether a single item is disabled you can use $("#textbox1").is(":disabled").

You can find if the textbox is disabled using is method by passing :disabled selector to it. Try this.

if($('textbox').is(':disabled')){
//textbox is disabled
}

You can check if a element is disabled or not with this:

if($("#slcCausaRechazo").prop('disabled') == false)
{
//your code to realice
}

 if($("element_selector").attr('disabled') || $("element_selector").prop('disabled'))
{


// code when element is disabled


}
