You have a syntax error in your script block. Change show_alert( to show_alert() on line 5 of your HTML page and it should function.

     function show_alert( )

here it seems extra space is given between "(" and ")". try this

       function show_alert()

May be it will solve.

Extra whitespace in JavaScript doesn't matter, so this would make no difference. – Hal Jan 10 '12 at 14:37
