用document.onreadystatechange的方法来监听状态改变,然后用document.readyState == “complete”判断是否加载完成。

document.onreadystatechange = subSomething;//当页面加载状态改变的时候执行这个方法.
function subSomething(){
if(document.readyState == “complete”) //当页面加载状态
myform.submit(); //表单提交
} 

页面加载readyState的五种状态,原文如下:

0: (Uninitialized) the send( ) method has not yet been invoked.

1: (Loading) the send( ) method has been invoked, request in progress.

2: (Loaded) the send( ) method has completed, entire response received.

3: (Interactive) the response is being parsed.

4: (Completed) the response has been parsed, is ready for harvesting.

翻译成中文为:

0 - (未初始化)还没有调用send()方法

1 - (载入)已调用send()方法,正在发送请求

2 - (载入完成)send()方法执行完成,已经接收到全部响应内容

3 - (交互)正在解析响应内容

4 - (完成)响应内容解析完成,可以在客户端调用了
