在IE浏览器中resize事件执行多次的解决方法
(编辑：jimmy 日期: 2026/1/1 浏览：3 次 )
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：
复制代码 代码如下:
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；
复制代码 代码如下:

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：
