用ajax调用php文件的数据
用来判断是否弹出登录框,
如果返回的值是156则会弹出登录框,
现在返回的值是156,但是不会弹出登录框<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

为什么不用jquery呢,一两句话就解决了,用起来还清晰明了。
所以说js效果应该不会有问题,
应写作
xmlhttp.onreadystatechange=cfunc;另外也没看到弹出对话框的代码
这个能执行到吗?
ajax就不能传值了
怎么在函数外面?
你可以看下div有没onchange之类的函数 用事件触发js代码 显示你的内容。
还有一种解决方案,你可以先写好div的内容 在ajax回调函数中做一个判断 满足条件 显示div即可 div.style.display='block' 这样JS不用去动态生成 线程也没那么复杂 代码也没那么多
