Jquery property disable

Is there any prope开发者_开发问答rty in jquery to help me check if a txtbox is disabled? and it lets me compare through an if statement?

for example:

 if ($('#ctl00_ContentPlaceHolder1_TextBox3'). == "false")
 {

 }

The :disabled selector was designed to do just that:

if ($("#ctl00_ContentPlaceHolder1_TextBox3").is(":disabled")) {
    // Text box is disabled.
}

If you're using jQuery 1.6 or higher, it's also safe to access the boolean DOM property with prop():

if ($("#ctl00_ContentPlaceHolder1_TextBox3").prop("disabled")) {
    // Text box is disabled.
}

You can use :disabled selector.

Try:

 if ($('#ctl00_ContentPlaceHolder1_TextBox3').is(":disabled"))  
 {    
 } 

or

 if ($('#ctl00_ContentPlaceHolder1_TextBox3:disabled').length)  
 {    
 } 

You can use the :enabled pseudoselector.

http://api.jquery.com/enabled-selector/

if($('#MyInput').attr('disabled') == 'disabled'){
    //Do something
}

$("#ctl00_ContentPlaceHolder1_TextBox3").is(":enabled")

will return the value of enabled status.

You can use .prop() if you are using jQuery 1.6+.

if ($('#ctl00_ContentPlaceHolder1_TextBox3').prop('disabled')) { ... }
