javascript - Jquery for slide change event

Question

My jquery code is like this

$(document).ready(function() {
    $(".slideshow").css("overflow","hidden");
    $("ul#slides").cycle({
    fx: 'fade',
    pause: 1,
    prev: '#prev',
    next: '#next'
});

And i want to know ,is there any slide change event in jquery for this...i mean i need to get the slide number when each slide changes

Thank you

Your question is about Cycle specifically, not general jQuery. The documentation on options for Cycle can be found here.

It looks like there is an event called onPrevNextEvent:

onPrevNextEvent: null,// callback fn for prev/next events: function(isNext, zeroBasedSlideIndex, slideElement)

The second parameter passed into a function you define for that event will be zeroBasedSlideIndex. That's your current slide number, with the first slide starting at 0.

So your code might look something like:

$(document).ready(function() {
    $(".slideshow").css("overflow","hidden");
    $("ul#slides").cycle({
    fx: 'fade',
    pause: 1,
    prev: '#prev',
    next: '#next',
    onPrevNextEvent: function(isNext, slideNum) {
        alert("This is slide "+ slideNum);
    }
});
