jQuery Mobile how to check if button is disabled?

2020-02-24 05:25发布

I disable the button like this on my jQuery Mobile webpage:

$(document).ready(function() {
    $("#deliveryNext").button();
    $("#deliveryNext").button('disable');
});

and i can enable it with

$("#deliveryNext").button('enable');

But how do i check if the button is disabled or enabled?

This command gives "undefined":

$("#deliveryNext").attr('disabled')

Some ideas?

Edit: i find out that $("#deliveryNext").button('disable') only seams to change the style on the button, the clicking works fine after so i need to disable the button some how also.. i tried .attr('disabled', 'disabled') but when i then test .attr('disabled') i get undefined...

Edit2: more about my "real" problem at How to disable a link button in jQuery Mobile?

            alert('disabled'); 
            $('#myButton').prop('disabled',false);

Try

$("#deliveryNext").is(":disabled")

The following code works for me:

<script type="text/javascript">
    $(document).ready(function () {
        $("#testButton").button();
        $("#testButton").button('disable');
        alert($('#testButton').is(':disabled'));
    });
</script>
<p>
    <button id="testButton">Testing</button>
</p>

What worked for me was this:

$("#testButton").hasClass('ui-state-disabled')

But I like tomwadley's answer a lot more.

Nevertheless, the is(':disabled') code does also not work for me which should be the best version. Don't know, why it does not work. :-(

$('#StartButton:disabled') ..

Then check if it's undefined.

Faced with the same issue when trying to check if a button is disabled. I've tried a variety of approaches, such as btn.disabled, .is(':disabled'), .attr('disabled'), .prop('disabled'). But no one works for me.

Some, for example .disabled or .is(':disabled') returned undefined and other like .attr('disabled') returned the wrong result - false when the button was actually disabled.

But only one technique works for me: .is('[disabled]') (with square brackets).

So to determine if a button is disabled try this:

$("#myButton").is('[disabled]');
