onclick函数在IE中不起作用，但在chrome和firefox中工作正常。我找不到错误。为什么正常功能不起作用。函数加载内容但是点击事件处理程序所写的前两个按钮不会改变IE中的按钮颜色。请帮帮我...提前致谢
The onclick functions do not work in IE but work fine in chrome and firefox. I could not find the mistake. Why a normal function does not work. function loads the contents but onclicking the first two buttons for which event handelers are writen does not change the button colour in IE only. Please help me... Thanks in advance
推荐答案
快速谷歌搜索表明问题是你在使用document.write之后页面已被加载，所以它也正在删除dom。你应该避免在页面加载后调用的函数中使用它。
quick googling suggests that the problem is that you are using document.write after the page has been loaded so it is erasing the dom as well. you should avoid using that in functions that are called after page loading.

我没有IE所以不能不测试它。
I dont have IE so couldn't test it.
