这是个让人每次改变页面窗口的大小时很郁闷的方法，尤其在IE浏览器中，稍微动下窗口边框，就会触发很多次事件。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导致resize事件再次被触发的时候，IE会随机陷入假死状态。
网上找了好久，都是千律一篇的，到处都是转载的一个方法；以下是网上找到的一个解决方法：
var resizeTimer = null;
$(window).resize(function() {
if (resizeTimer) clearTimeout(resizeTimer);
resizeTimer = setTimeout("changeHeight()", 500);
});//resize事件延迟500毫秒执行
这个方法虽然可以解决多次执行事件问题，但是不完美，最后我找到了一个jquery插件形式的解决方案；

你可以把上面的代码另存为jquery.wresize.js导入网页,把以下代码拷贝到记事本中，另存为网页，然后测试一下。示例：
test window resize
test test testtest test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test
