通过本文主要向大家介绍了jQuery,jrumble,抖动等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
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

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
