I have a jquery mobile slider on a simple page. When I drag the slider, the value updates as expected in the textbox. I have looked but cannot find where this logic is happening.

What I would like, is to pass the value into a javascript function. How can I bind the change event to my function?

Cheers

Mike.

I'm not too familiar with jquery mobile, but adding a change handler to the original input element should do:

$('#slider-1').change(function(){
    var slider_value = $(this).val()
    console.log(slider_value)
    // do whatever you want with that value...
})

Hope this help,

Martin

Shortest yet and functional. 

$('body').change(function() {
    var slider_value = $('#slider-1').val();
    if(slider_value == 4000){   
        alert("Holy smoke!");
    }
}

I had the same problem, too many troubles with the event of the slider. Finally I found 'slidestop' event that works great. This is the code:

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

I hope this work for you

try this:

var self = this;
this.sliderTouchUp = function() {
    var currentVal = $('#slider-1').val();
    console.log("val change to " + currentVal);
};
$('.ui-slider').live('mouseup', self.sliderTouchUp);
$('.ui-slider').live('touchend', self.sliderTouchUp);
