How to remove an element AFTER animation completes?

问题

I'm using the following code to animate a div.

<script>
  $(function() {
    $("a.shift").click(function() {
      $("#introOverlay").animate({
        height: 0,
      }, 2000)
    });
  });
</script>

When the animation finishes, I would like to remove it. How can I do that?

回答1:

animate takes 2 more params, so you could do:

$("a.shift")
    .click(function() 
        {
            $("#introOverlay")
                .animate({height: 0}, 2000,"linear",function()
                    {
                        $(this).remove();
                    }
                )
        }
    );

Untested.

EDIT: Tested: here's the full page I used, which expands to 300px make removal more obvious:

                {
                    $("#introOverlay")
                    .animate({height: 300}, 2000,"linear",function()
                    {
                        $(this).remove();
                    })
                });
            });
            //]]>
        </script>
    </head>
    <body>
    <a class="shift" href="javascript:void(0)">clickme</a>
    <div id="introOverlay" style="background-color:red;height:200px;">overlay</div>
    </body>
</html>

JQuery animate(params, [duration], [easing], [callback] ) offers the possibility to add a callback that is called for every time the animation is completed

callback (Optional) Function: A function to be executed whenever the animation completes, executes once for each element animated against.

The syntax is pretty much jQuery straightforward:

<script>
$(function() {
    $("a.shift").click(function() {
        $("#introOverlay").animate({
        height: 0,
        }, 2000, "linear",
            function() {
                $("#introOverlay").hide();
            }
        )
        });

    })
</script>

回答3:

Put the remove() call in the effects queue like this:

$("a.shift").click(function() {
  $("#introOverlay").animate({
    height: 0,
  }, 2000);
  $("#introOverlay").queue(function() {
    $(this).remove();
    $(this).dequeue();
  });
});

Use window.timeout with the same amount of time as taken by the animation.
