Javascript setInterval not working

Question

I need to run a javascript function each 10 seconds.

I understand the syntax must work like follow but I am not getting any success:

function funcNam         


        

Answer 1

That's because you should pass a function, not a string:

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

setInterval(funcName, 10000);

Your code has two problems:

• var func = funcName(); calls the function immediately and assigns the return value.
• Just "func" is invalid even if you use the bad and deprecated eval-like syntax of setInterval. It would be setInterval("func()", 10000) to call the function eval-like.
