Unable to call javascript code

Question

In Mainpage...html

<script type="script/javascript">
function SayHi()
{
   alert("Oke.Hai..(waving)!")
}
</script>

and in xaml simpley thereis a button

<button name="Btn" width="100" content="Say 2!" Click="Btn_Click">

</button>

Then in the cs file within the button click event

HtmlPage.Window.Invoke(SayHi);

Yuyik, a runtime error "Unable to to invoke the method in in click event, Debug ?"

It's simple just that. Any help is appreciated.

A script's type should be text/javascript, not script/javascript. — Delan Azabani

You need to wrap the method name with double quotes otherwise it mistakes it as variable name:

HtmlPage.Window.Invoke("SayHi");
