Fading in/out a jquery list

Related searches

I'm trying to write a jquery function that loops through an unordered list (the ul element having the id "intro") and individually fades in and fades out each element. This doesn't work, but I get no errors in the developer tools. I also tried changing var list = $("#intro"); to var list = $("#intro li"); but no dice with that either

<script type = "text/javascript">
        function startAnimations(){

            var list = $("#intro");
            list.hide();
            list.each(function(li) {
                $(li).fadeIn(3000, function(){
                    $(li).fadeOut(3000);
                });

            });
        }
    </script>

Since the html was asked for:

<body onload="startAnimations()">
    <div class = "container">
        <div id = "inner">  </div>
        <div id = "right-col">
            <ul id = "intro">
                <li id = "greeting"> <h2 > sometext </h2> </li>
                <li id = "sidenote"> <h6 >  sometext </h6> </li>
                <li id = "sentence"> <h3 >  sometext </h3> </li>
                <li id = "sentence"> <h3 >  sometext</h3> </li>
                <li id = "sentence"> <h3 >  sometext</h3> </li>
            </ul>
        </div>
    </div>

</body>

Try

function startAnimations() {
    $("#intro li").hide();

    function loop() {
        var $li = $("#intro li:first-child").fadeIn(3000, function () {
            $li.fadeOut(3000, function () {
                $li.appendTo('#intro');;
                loop()
            })
        });
    }
    loop()
}

jQuery Effects - Fading, The jQuery fadeToggle() method toggles between the fadeIn() and fadeOut() methods. If the elements are faded out, fadeToggle() will fade them in. If the elements are faded in, fadeToggle() will fade them out.

You can use:

function fadeLi(elem) {
    elem.delay().fadeIn().delay(1500).fadeOut(500, function () {
        if (elem.next().length > 0) {
            fadeLi(elem.next());
        } else {
            fadeLi(elem.siblings(':first'));
        }
    });
}

$(function () {
    $('#intro li').hide();
    fadeLi($('ul li:first'));
});

.fadeOut(), Description: Hide the matched elements by fading them to transparent. Animates all paragraphs to fade out, completing the animation within 600 milliseconds. As of jQuery 1.4.3, an optional string naming an easing function may be used. Easing functions specify the speed at which the animation progresses at different points within the animation. The only easing implementations in the jQuery library are the default, called swing, and one that progresses at a constant pace, called linear.

function startAnimations(){

             $("#intro").hide();

            $("#intro li").each(function() {
                 var _this = $(this);

                _this.fadeIn(3000, function(){
                    _this.fadeOut(3000);

                });

            });
        }

.fadeIn(), .fadeIn( [duration ] [, complete ] )Returns: jQuery. Description: Display the matched elements by fading them to opaque� jQuery fadeToggle() Method. The jQuery fadeToggle() method display or hide the selected elements by animating their opacity in such a way that if the element is initially displayed, it will be fade out; if hidden, it will be fade in (i.e. toggles the fading effect).

I think you are not selecting the li like you want. Try like this:

<script type = "text/javascript">
        function startAnimations(){

            var list = $("#intro li");
            list.hide();
            list.each(function(index) {
                $(this).fadeIn(3000, function(){
                    $(this).fadeOut(3000);
                });

            });
        }
    </script>

The first parameter of this "each" function is not the element itself. It is the index

.fadeToggle(), To Donate, see this list of organizations to support from Reclaim the Block Fades first paragraph in or out, completing the animation within 600 Fades last paragraph in or out for 200 milliseconds, inserting a "finished" message upon� jQuery comes with three handy methods to create the fading effect easily. fadeIn() – Display the matched elements with fade in effect. fadeOut() – Hide the matched elements with fade out / transparent effect. fadeTo() – Fading the matched elements to certain opacity.

Most of these look like good solutions. I may be reading into your question, but I'm assuming the advantage of fading each in & out individually is so you can stagger the transitions.

If that's the case, I'd recommend using jQuery's .delay() method:

I've forked the jsfiddle @arun made to show you how it could be done:

http://jsfiddle.net/Lgwm8/1/

function startAnimations() {
  var list = $("#intro li");
  list.hide();
  list.each(function (i, li) {
    $(li).delay(i * 500).fadeIn(3000, function () {
      $(li).fadeOut(3000);
    });
  });
}
startAnimations();

.fadeTo(), To Donate, see this list of organizations to support from Reclaim the Block fadeIn() method but that method unhides the element and always fades to 100% Fade div to a random opacity on each click, completing the animation within 200� To make this more complete, I experimented showcasing product catalog with fade-in and fade-out transitions while switching between grid and list views. In this post, let us see how to create fading list/grid view switcher with components to display product catalog using jQuery and css.

Properly syncing the various fades took a little planning. Note the combined time for .fadeIn() and .delay() for the first image is five seconds, equal to the timing on the .delay() for the second image. Also note that the first image takes 1.5 seconds to fade out while the second one takes the same amount of time to fade in. This keeps

Definition and Usage. The fadeIn() method gradually changes the opacity, for selected elements, from hidden to visible (fading effect). Note: Hidden elements will not be displayed at all (no longer affects the layout of the page).

  • can you share the html as well
  • you are grabbing an element with an id and you are trying to iterate it...?!?!
  • list.each doesn't make sense since IDs must be unique.
  • see jsfiddle.net/arunpjohny/3DJkg/1
  • try jsfiddle.net/arunpjohny/3DJkg/4
  • @JasonMarmon since you want to display only 1 item at a time, we display the first child, then fadeout it after a while... once the item is hidden we move to to the last child of the ul by calling appendTo because now we have to display the second item, if we move the current item to the last position, then the second item become the first child now so that we can repeat the loop
