document.write() alert() 的问题
May 16, 2007 Author: | Filed under: Uncategorized看到这个老问题，ie 下button会被清掉，导致错误。
[Ctrl+A 全部选择 提示：你可先修改部分代码，再按运行]
为什么代码“alert(”);”被执行了，而“document.write(’456′);”没被执行？
我觉得qazwsx_feng 的解释有点道理
以下为引用内容:
alert();是window的方法！write是document的方法，
button按下后window.document已经不是最初的document而是提交后的document
而由于window对象仍然是最初的window对象它的方法仍可执行。
下面的代码在ie和firefox的表现也不一样
[Ctrl+A 全部选择 提示：你可先修改部分代码，再按运行]
有点头昏了，谁有更好的解释
