Hello,

I am using web browser control in C#2.0. I need to insert the Javascript dynamically in the head section of the page and invoke that script dynamically. Can please anyone tell me how to do that?

p.s. Script doesn't return any values as it is a very simple script.

Thanks.

 Should be possible by following theses steps:

• Get a reference to the document
• get a reference to the head element - getElementsByTagName("head")[0]
• create a new script element - document.createElement("script")
• Add the actual script to the script element using innerText
• Append the script element to the head

If all that is incomprehensible then you need to brush up on the Document Object Model. The process would be the same in a browser so maybe practice on that first to make sure it works.

Joe,

Thanks for your suggestion. I'm afraid the SCRIPT element doesn't have an innerText property. If I try to set it in the code I get the following exception "Property is not supported on this type of HtmlElement.".
Here is the code I'm using:
HtmlElement s = LPBrowser.Document.CreateElement("script");
try
 {
    //this line throws an exception
    s.InnerText = "function test(){}";
}
catch(Exception ee)
{}


Do you have any ther suggetion?

The following seems to work:

webBrowser1.Document.Write("<script>document.write ('hello world')</script>");

Okay, you can perhaps set the innerHTML or append the actual script as a text node. Use createTextNode and appendChild.
