to call a javascript function periodically

I want to call function with arguement periodically.

I tried setTimeout("fnName()",timeinseconds); and it is working.

But when I add an arguement it won't work. eg: setTimeout("fnName('arg')",timeinseconds);

setTimeout accepts an expression or a function name or an anonymous function but NO () operator.

() will start executing the function immediately and results in setTimeout accept an invalid parameter.

Use an anonymous function, like this:

setTimeout(function() { fnName('arg'); }, time);

In general, never pass a string to setTimeout() or setInterval() if you can avoid it, there are other side-effects besides being bad practice...e.g. the scope you're in when it runs.

Just as a side-note, if you didn't need an argument, it's just:

setTimeout(fnName, time);

You can add an anonymous function:

setTimeout(function() { fnName("Arg"); }, 1000);
