jquery to create a fading effect for individual list items

I have a group of items listed, and I would like them to smoothly fade out while the next one fades in seamlessly. Below is the code I've been working on:

    document.ready(function(){

        var list_slideshow = $("#site_slideshow_inner_text");
        list_slideshow.children("li:not(:first)").hide();
        
        function changeList(){
            var list_slideshow = $("#site_slideshow_inner_text");       
            var length = 0;
            
            if(list_slideshow.length === length)
            {
                list_slideshow.children("li").eq(0).fadeOut(300, function()  
                            {
                $(this).next().fadeIn(300);
                });
            }
        }
        setTimeout(changeList(), 500);
});

Answer №1

Here are a few issues with your code implementation:

  1. The syntax for calling the setTimeout function is incorrect (use changelist instead of changelist()).

  2. Instead of using setTimeout, consider utilizing setInterval for repeated calls.

  3. The document ready function was called incorrectly (use either $(document).ready(function () { or $(function () {).

  4. There is an issue in the logic within the changeList function (e.g., list_slideshow.length === length will always be false).

The code snippet below should help you achieve the intended functionality, with potential adjustments to timings:

$(function () {
    var list_slideshow = $("#site_slideshow_inner_text"),
        listItems = list_slideshow.children('li'),
        listLen = listItems.length,
        i = 0,
        changeList = function () {
            listItems.eq(i).fadeOut(300, function () {
                i += 1;
                if (i === listLen) {
                    i = 0;
                }
                listItems.eq(i).fadeIn(300);
            });
        };
    listItems.not(':first').hide();
    setInterval(changeList, 1000);
});
