jquery disable a button for a specific time

Question

i want to disable a button for a specific time. how can i do that?

Answer 1

Disable the button and then use setTimeout to run a function that enables the button after a few seconds.

$('#some-button').attr("disabled", "disabled");
setTimeout('enableButton()', 5000);

function enableButton(){
   $('#some-button').removeAttr('disabled');
}

Since this is likely to be a task you might like to repeat, I think the best way to do this would be to extend jQuery like so:

$.fn.timedDisable = function(time) {
    if (time == null) { time = 5000; }
    return $(this).each(function() {
        $(this).attr('disabled', 'disabled');
        var disabledElem = $(this);
        setTimeout(function() {
            disabledElem.removeAttr('disabled');
        }, time);
    });
};

This will allow you to call a function on a set of matched elements which will temporarily disable them. As it is written, you can simply call the function, and the selected elements will be disabled for 5 seconds. You would do that like so:

$('#some-button').timedDisable();

You can adjust the default time setting by changing the 5000 in the following line:

if (time == null) { time = 5000; }

You can optionally pass in a time value in milliseconds to control how long the elements will be disabled for. For example:

$('#some-button').timedDisable(1000);

Might not be the most elegant solution, but I thought I'd play with jQuery queues on this one...

​$.fn.disableFor = function (time) {
    var el = this, qname = 'disqueue';
    el.queue(qname, function () {
        el.attr('disabled', 'disabled');
        setTimeout( function () {
            el.dequeue(qname);
        }, time || 3000);
    })
    .queue(qname, function () {
        el.removeAttr('disabled');
    })
    .dequeue(qname);
};

$('#btn').click( function () {
    ​$(this).disableFor(2000);​​​​
});

​ This is where I worked it out... http://jsfiddle.net/T9QJM/
