Trigger a jQuery UI slider event

Question

How can I trigger a change event on a jQuery UI slider?

I thought it would be

$(\'#slider\').trigger(\'slidechange\');

but that do

Answer 1

The jQueryUI Slider documentation gives the following example for triggering an event:

$( ".selector" ).slider({
    change: function( event, ui ) {}
});

and for the event trigger:

$( ".selector" ).on( "slidechange", function( event, ui ) {} );

this didn't work for me!

All I had to do to get it working was to change "slidechange" to "change".

$( ".selector" ).on( "change", function( event, ui ) {} );

Hope this helps the future generations that stumbleupon this problem.

Answer 2

Try

$slider = $('#slider');
$slider.slider('option', 'change').call($slider);

Not ideal but gets you working!

Answer 3

I Used both slidechanged and slide, slide triggers when drag the point, slidechanged triggers after release the mouse button (just like click event)

var slider1 = $("#slider1").slider({ min: 1, max: 6 });
//option 1
slider1.on("slide", function (e, ui) {

});
//Option 2
slider1.on("slidechanged", function (e, ui) {

});

Wanted to add a comment on Joey Yore's answer -

I think it's better the other way round

$('#slider').bind({
    slidestart  : function(event,ui) {...},
    slidechange : function(event,ui) {...},
    slidestop   : function(event,ui) {...},
    slidecreate : function(event,ui) {...}
}).slider();

Otherwise some events (namely, 'slidecreate') will be ignored

Answer 5

If you bind to to the slider's change event like that:

$('#slider').change(function() {
    alert('action');
});

Then you can trigger it like:

$('#slider').trigger('change');

The solution below mentioned by Joey Yore works too, but the downside is that slidechange event is not fired (from my experience) when user changes your slider from UI.

//TO DEFINE SLIDER AND EVENTS
$('#slider').slider().bind('slidechange',function(event,ui){...});

//TO TRIGGER EVENT
$('#slider').trigger('slidechange');

Answer 6

I found it easier to use the 'create' method to call the slide or stop function. Eg, for a slider with a min/max range:

$('#height').slider({
        ...
        create: function(event, slider){ $( "#height" ).slider( "option", "values", [1100, 1500] ); handleHeightSlide('slide', $( "#height" ));},
        ...
    });
