jQuery .prop("disabled", false) is not enabling an input

Question

I'm having a problem re-enabling an input after it has been disabled on the page load.

I'm using two inputs to accept two dates, but I want it that the second input is not enabled until the first one has a value.

<div id="date1" data-role="fieldcontain">
    <label for="date1-start" id="date1-startlbl">Start Date</label>
    <input name="date1-start" id="date1-start" type="date" data-role="datebox"data-options='{"mode": "calbox", "overrideDateFormat": "%Y-%m-%d", "beforeToday": true}' data-theme="a" onchange="showdate()"/>
    <label for="date1-end" id="date1-endlbl">End Date</label>   
    <input name="date1-end" id="date1-end" type="date" data-role="datebox" data-options='{"mode": "calbox", "overrideDateFormat": "%Y-%m-%d", "beforeToday": true}' data-theme="a" onchange="datechart()"/>
</div>

The second input is disabled successfully on the page load with.

$("#date1-end").prop("disabled", true);

The first date has an onchange event that calls the following function

function showdate(){
    if ($("#date1-start").val() != null){
        if ($("#date1-end").val() != ""){
            datechart();
        }
        else{
            $("#date1-end").prop("disabled", false);
            $("#date1-end").trigger('change');
        }
    }
}

The function is called and prop("disabled", false) when reached fires without any errors, but the input remains disabled. The trigger('change') I am using is an attempt at refreshing the element but the same problem exists without it.

I have tried different variations of .attr from an older version of Jquery but I also get the same problem.

I am using Jquery 1.9.1, Jquery-mobile 1.3.1 and PhoneGap 2.7.0

Working example: http://jsfiddle.net/d9vzs/

This is not how you enable disable jQUery Mobile input elements.

It can be done with this functions:

$( "input" ).textinput( "disable" );


$( "input" ).textinput( "enable" );

Official documentation: http://api.jquerymobile.com/textinput/#method-disable

Solution 2

Had the same problem some time ago:

$("#date1-end").prop("disabled", null);

@Gautam3164's answer is also good.

Solution 3

Try with removeAttr like

$("#date1-end").removeAttr("disabled");

You can also try with prop like

$("#date1-end").prop("disabled",false);

Sorry should have elaborated with .attr that I have also tried this, but I am still getting the same problem.

[RichardMc]

That was what I had originally been using but I get the same problem. I have read I may need to refresh the element after enabling it. Is there any truth in that?

[RichardMc]

This worked great. Should have looked through the Jquery mobile docs instead of just Jquery. Thanks.

Scroll the page you've provided the link for, below you will see that prop also used to set the value.

What is the difference between your two functions?

@JeffPuckettII There was a typo, and I edited the second function to "enable".

So unintuitive!! This works though - thank you!
