jquery - jQueryMobile: how to work with slider events?

I'm testing the slider events in jQueryMobile and I must been missing something.

page code is:

<div data-role="fieldcontain">
    <label for="slider">Input slider:</label>
    <input type="range" name="slider" id="slider" value="0" min="0" max="100"  />
</div>

and if I do:

$("#slider").data("events");

I get

blur, focus, keyup, remove

What I want to do is to get the value once user release the slider handle

and having a hook to the keyup event as

$("#slider").bind("keyup", function() { alert('here'); } );

does absolutely nothing :(

I must say that I wrongly assumed that jQueryMobile used jQueryUI controls as it was my first thought, but now working deep in the events I can see this is not the case, only in terms of CSS Design.

What can I do?

jQuery Mobile Slider source code can be found on Git if it helps anyone as well a test page can be found at JSBin


As I understand, the #slider is the textbox with the value, so I would need to hook into the slider handle as the generated code for this slider is:

<div data-role="fieldcontain" class="ui-field-contain ui-body ui-br">
    <label for="slider" class="ui-input-text ui-slider" id="slider-label">Input slider:</label>
    <input data-type="range" max="100" min="0" value="0" id="slider" name="slider" class="ui-input-text ui-body-null ui-corner-all ui-shadow-inset ui-body-c ui-slider-input" />
    <div role="application" class="ui-slider  ui-btn-down-c ui-btn-corner-all">
        <a class="ui-slider-handle ui-btn ui-btn-corner-all ui-shadow ui-btn-up-c" href="#" data-theme="c" role="slider" aria-valuemin="0" aria-valuemax="100" aria-valuenow="54" aria-valuetext="54" title="54" aria-labelledby="slider-label" style="left: 54%;">
            <span class="ui-btn-inner ui-btn-corner-all">
                <span class="ui-btn-text"></span>
            </span>
        </a>
    </div>
</div>

and checking the events in the handler anchor I get only the click event

$("#slider").next().find("a").data("events");

Fix

From Ivan answer, we just need:

<div data-role="fieldcontain">
    <label for="slider">Input slider:</label>
    <input type="range" name="slider" id="slider" value="0" min="0" max="100"  />
</div>

and then

$(document).bind("pagecreate", function(event, ui) {

    $('#slider').siblings('.ui-slider').bind('tap', function(event, ui){ makeAjaxChange($(this).siblings('input')); });
    $('#slider').siblings('.ui-slider a').bind('taphold', function(event, ui){ makeAjaxChange($(this).parent().siblings('input')); 

});

function makeAjaxChange( elem ) { 
    alert(elem.val()); 
}

Thank you Ivan for the heads up.

Try this code:

$( "#slider-1").on('slidestop', function( event ) {
   var slider_value=$("#slider-1").slider().val();
   alert('Value: '+slider_value);
});

I hope this work for you
