I am learning how to automate tasks on Websites.I have an html snippet which contains a JavaScript Code which i wish to invoke programmatically using WebBrowser Control.I am using IE11 for Emulation.I cannot edit the Website Source.
How to invoke the JS Code.

HTML

<a style="removed: auto ! important;" id="13185-SL-CK-0" href="javascript:jpBook($('#13185-SL-CK-0'),'13185','SDAH','DBG','24-10-2015','SL','CK',3,false);" tabindex="1">Book Now</a>

In my MozillaBrowser Console when i paste the content of href i get the desired results(the JS is executed).But in WinForms. I have tried

C#

webBrowser1.Navigate("javascript:jpBook($('#13185-SL-CK-0'),'13185','SDAH','DBG','24-10-2015','SL','CK',3,false);");

C#

webBrowser1.Document.InvokeScript("javascript:jpBook($('#13185-SL-CK-1'),'13185','SDAH','DBG','24-10-2015','SL','CK',3,false);");

without any luck. A simple solution could be to access the button and click it but i don't want to do that

Have you tried to follow this example on MSDN? WebBrowser.InvokeScript Method (String, Object[])[^]

Some times it helps to go back to basics and then add on more complexity.

You have to modify the JavaScript method, though.

HTML

<html>
    <head>
        <script type="text/javascript">
            // Function With Parameters
            function JavaScriptFunctionWithParameters(message)  
            {
              outputID.innerHTML = "JavaScript function 'called: " + message + ".";
            }
        </script>
    </head>
    <body>
    
        Hello from HTML document with script!
    
    </body>
</html>

Make sure that your document finished loading before you invoke the Java script.

You could try to add this meta data inside the <head> tag.

HTML

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

I think the WebBrowserControl defaults to IE7 otherwise.

If I remember correctly you also need to add your application to the registry in order to enable IE9.

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"WDExpress.exe"=dword:0000270f
"devenv.exe"=dword:0000270f
"AcroRd32.exe"=dword:0000270f
"<Yourapplication>.exe"=dword:0000270f

Can't remember exactly where I found the information about this, but I think it was Stack Overflow.
