resize事件是在窗口或框架的大小被调整时发生，包括最小化、最大化。在IE和Opera浏览器中，只要窗口边框被拖动，就触发该事件，在Mozilla浏览器中，resize 事件只是在中止改变窗口大小时才会触发。
这是个让人每次改变页面窗口的大小时很郁闷的方法，尤为在IE浏览器中，稍微动下窗口边框，就会触发不少次事件。更让人蛋疼的是在resize事件中包含某些页面内容处理或计算致使resize事件再次被触发的时候，IE会随机陷入假死状态。javascript
其实这个问题有两种方法解决：php
1.css
var resizeTimer = null; |
$(window).resize(function() { |
if (resizeTimer) clearTimeout(resizeTimer); |
resizeTimer = setTimeout("changeHeight()", 500); |
});//resize事件延迟500毫秒执行 |
2.推荐用jquery插件html

你能够把上面的代码另存为jquery.wresize.js导入网页,把如下代码拷贝到记事本中，另存为网页，而后测试一下。示例：jquery
