Interaction between JavaScript and Windows Forms

Question

i have a Windows Forms application, which uses a Webbrowsercontrol to display a dynamically generated Htmlpage. Is there a possibility to interact with the jscode of the page? For example if i have have the following function:

<script type="text/javascript">
function ReturnValue()
{
var output;
output ='test';
return output;
}
</script>

Would there be a possibility to receive "test" in my application (not trough url)?

Maybe something like InvokeScript could help? msdn.microsoft.com/en-us/library/… Just guessing, never done it. — Gray

Yes, that would be usefull if i wanted to execute a jsfunction from my application, but the function is called f.e. on the onclickevent of a button (so i dont have any authority when it occures) and i want the result. I dont want to call a fuction, a ionly want the result — BudBrot

Maybe make the variable you want have a bigger scope, and then write a method that returns it... then call that? Might be a better way, but that sounds like it would work. — Gray

Yes it's possible using InvokeScript on the browser control; see this article for more information: http://www.codeproject.com/Tips/127356/Calling-JavaScript-function-from-WinForms-and-vice
