如何加载更新的内容以使用webbrowser控件进行一些处理 [英] How to load the the updated content to do some processing using webbrowser control

问题描述

I'm using a WebBrowser control in my app to load a page that updates its content dynamically via Ajax. I need to access the updated content to do some processing, but since the calls are made with Ajax the page doesn't get refreshed and thus the DocumentComplete event doesn't fire. 
Is there a way to get notified when a call is made using the XMLHttpRequest object? Some event fires maybe?
Any help will be appreciated,

I don't try any thing in this matter

推荐答案

XMLHttpRequest 有一个属性onReadyStateChange。



您可以为此分配一个函数，例如：

XMLHttpRequest has a property onReadyStateChange.

You can assign a function to this such as:

var xmlHttpReq;  // You need to fill-in details for creation of this
                 // request object and triggering the request etc.

function respAjax() {
  if (xmlHttpReq.readState == 4) {
    // Request has finished and response is ready.
    // Do whatever you want here..
  }
}

xmlHttpReq.onReadStateChange = respAjax;
