 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Me.WebBrowser1.Document.InvokeScript("javascriptFunction", _
New String() {"2", "3"})
End Sub

i am new In javascript.So plz any suggestion

A few observations: 1.) Not java script, but javascript. 2.) How do you want to pass a value to javascript from a different language? — Endre Simo

@SimoEndre It's possible because he forgot to tell that he's invoking js inside a WebBrowser control in .Net Winforms — Oscar

Your javascript function doesn't receive any parameters as it's declared now. It should be declared as:

function javascriptFunction(x, y) {
    var z = x + y;
    alert(z);
}

@SimoEndre Why not? He's passing the params correctly, but there isn't any js function that match with those parameters right now. msdn.microsoft.com/en-us/library/4b1a88bz%28v=vs.110%29.aspx
