JavaScript判断页面是否加载完成

JavaScript判断页面是否加载完成

 

 

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

 

代码如下

 

 

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
