我有一个Winforms表单,上面有WebBrowser control

我已经找到了如何通过将C#类的实例附加到ObjectForScripting属性来将C#代码连接到Web浏览器控件中的Javascript,如下所示:

public partial class Browser : Form
{
    private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        webBrowser1.ObjectForScripting = new ScriptInterface();
    }
}

[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[ComVisible(true)]
public class ScriptInterface
{
    public void DoSomething(string data)
    {
        // Do something interesting with data here
    }
}

...然后从Javascript中调用它:

<button onclick=window.external.DoSomething('with this')/>

我还没想到的是如何从WebBrowser控件中的表单捕获POST操作的结果,并在我的C#代码中使用它。

您可以使用jQuery post代替表单帖子。

假设您的表单的ID为myForm

$( "#myForm" ).submit(function( event ) {     
  // Stop form from submitting normally
  event.preventDefault();

  // Get some values from elements on the page:
  var $form = $(this),
  var term = $form.find("input[name='s']").val(),
  var url = $form.attr("action");

  // Send the data using post
  var posting = $.post( url, { s: term } )
      .done(function(data) {
          //Pass the response back to your code
          window.external.DoSomething(data);
      });
});
