在这种情况下如何从C＃调用WebBrowser控件中的JavaScript

Question

sorry, my poor English,my question is as following:

Calling JavaScript in a WebBrowser control from C# in ordinary way: JavaScript

function showMe()

{ ... }

C#

webBrowser1.Document.InvokeScript("showMe");

that is ok!

but how to call in such situation:

html:

<a href="javascript:void(0);" onclick="App.followcancel('1880161672',this,'0','A','B');return false;">hello</a>

c#:

webBrowser1.Document.InvokeScript(????????)

I don't know how to write the correct paremeter to achieve the onclick's javascript

anyone help me,thanks a lot

Answer 1

Something like this (if you set id of the link to "mylink"):

HtmlElement el = webBrowser1.Document.All["mylink"];
object obj = el.DomElement;
System.Reflection.MethodInfo mi = obj.GetType().GetMethod("onclick");
mi.Invoke(obj, new object[0]); 

Answer 2

Following the example you've given:

webBrowser1.Document.InvokeScript("App.followcancel('1880161672',this,'0','A','B')");

Edit: This example is broken.

You would need to replace 'this' with document.getElementById('mylink') (assuming an id attribute is set with the value mylink ) or use the approach given by HABJAN.
