Call Javascript function from C# static web method (page method)

Question

I used:

ScriptManager.RegisterStartupScript(this, GetType(), "", "MyJSFunction('parameter')", true);

to reach the MyJSFunction function in JavaScript from Page_Load and it worked fine. Now I'm in need of calling lets say the same function but from a static web method, but I get these 2 errors on this & GetType():

this: Keyword 'this' is not valid in a static property, static method, or a static field initialized.

GetType(): An object reference is required for the non-static field, method, or property, 'objec.GetType()'.

I tried to re-format the code like this:

ScriptManager.RegisterStartupScript((Page)(System.Web.HttpContext.Current.Handler), ((Page)(System.Web.HttpContext.Current.Handler)).GetType(), "", "MyJSFunction('parameter')", true);

No errors shown, but it doesn't reach the JavaScript function.

Can anyone help?

Call the JavaScript function upon successful completion (callback) of the call to the web method in your JS code. You can't "call" client-side code from the code behind; you can register a JS function call as a "startup script" but not here as a call to a web method does not involve a postback of the page nor does it cause Page_Load to run.
