Access C# Variable From JavaScript

Question

I have a public property in my code behind named Tab which I'm trying to access in the pages aspx file with javascript but I'm not sure how to get the right value.

This gives me the value I want

alert('<% Response.Write(this.Tab); %>');

This does not

 var x = <% =this.Tab %>;
 alert(x); 

Any ideas?

Answer 1

If you view the source you are probably seeing

var x = mystring;

I would guess you want the quotes too

var x = "<%= this.Tab %>";

Instead of having code inline, why don't you look at RegisterStartUpScript or RegisterClientScriptBlock.
