jQuery插件jRumble实现网页元素抖动

jRumble，它能让网页上的任意元素抖动起来，在你的网站中使用这个效果会有很大的机率吸引用户的注意力。此插件的效果可以用在链接上，或者div上，你可以设置抖动的范围、XY坐标、抖动幅度等。可设置为当鼠标移动上去抖动或者默认一直抖动，插件可定制性还是蛮高的。PS:此插件在IE中还存在一些小问题

jQuery jRumble是使用方法

<script type="text/javascript" src="js/jquery-jrumble.js"></script>
<script type="text/javascript">
$(document).ready(function(){
 $('#demo1').jrumble({
 rangeX: 2,
 rangeY: 2,
 rangeRot: 1
 });

 $('#demo2').jrumble({
 rangeX: 10,
 rangeY: 10,
 rangeRot: 4
 });

 $('#demo3').jrumble({
 rangeX: 4,
 rangeY: 0,
 rangeRot: 0
 });

 $('#demo4').jrumble({
 rangeX: 0,
 rangeY: 0,
 rangeRot: 5
 });

 $('#demo5').jrumble({
 rumbleSpeed: 0
 });

 $('#demo6').jrumble({
 rumbleSpeed: 50
 });

 $('#demo7').jrumble({
 rumbleSpeed: 100
 });

 $('#demo8').jrumble({
 rumbleSpeed: 200
 });

 $('#demo9').jrumble({
 rumbleEvent: 'hover'
 });

 $('#demo10').jrumble({
 rumbleEvent: 'click'
 });

 $('#demo11').jrumble({
 rumbleEvent: 'mousedown'
 });

 $('#demo12').jrumble({
 rumbleEvent: 'constant'
 }); 

 $('#demo13').jrumble({
 posX: 'left',
 posY: 'top'
 });

 $('#demo14').jrumble({
 posX: 'right',
 posY: 'top'
 });

 $('#demo15').jrumble({
 posX: 'left',
 posY: 'bottom'
 });

 $('#demo16').jrumble({
 posX: 'right',
 posY: 'bottom'
 }); 

 $('.view-source pre').hide();
 $('.view-source a').toggle(function(){
 $(this).siblings('pre').stop(false, true).slideDown(500);
 $(this).html('Hide Source');
 }, function(){
 $(this).siblings('pre').stop(false, true).slideUp(500);
 $(this).html('View Source');
 });
});
</script>

jRumble的参数配置

Option Default Description
rangeX 2 Set the horizontal rumble range (pixels)
rangeY 2 Set the vertical rumble range (pixels)
rangeRot 1 Set the rotation range (degrees)
rumbleSpeed 10 Set the speed/frequency in milliseconds of the rumble (lower number = faster)
rumbleEvent ‘hover' Set the event that triggers the rumble (‘hover', ‘click',‘mousedown', ‘constant')
posX ‘left' If using jRumble on a fixed or absolute positioned element, choose ‘left' or ‘right' to match your CSS
