Question

i want to do a setInterval of a function that is at the same level as the declaration of the setinterval but not global

Example:

function a()
{
    function b(){alert("hi");}
    setInterval("b()",1000);
}

Answer 1

In your example, simply use setInterval(b, 1000) instead of setInterval("b()", 1000).

I’d go as far as to say you should always use setInterval and setTimeout with a real function instead of a string.
