  • 用js判断页面是否加载完成实现代码

    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
