setInterval and [removed] problem

Question

I have this code

window.onload = function() {            
    function foo() {
        alert(\"test\");
    }
    setInterval(\"foo()\",500)
}

Answer 1

Try this:

function foo() {
    alert("test");
}

window.onload = function() {            
    setInterval("foo()",500)
}

It works for me.
