Question

I use jQuery UI Slider element and I want to change the position of slider without user’s action – only by code. is there any case to do it?

Answer 1

Set the value option of the slider. This example sets the initial value to 50 on a scale of 0 to 100 then moves it to 25 after a three second delay:

$('#slider').slider({
    max: 100,
    min: 0,
    value: 50,
    disabled: true
});
setTimeout(function() {
    $("#slider").slider("option", "value", 25);
}, 3000);​
