How can I pass a parameter to a setTimeout() callback?
Is there ever a good reason to pass a string to setTimeout?

I want to call a function loadPHPQuote(code) after 1 second. And want to pass the parameter called code which is containing both numbers and text characters. But setTimeout() wasn't work if the code contain a character it is OK with only numbers.

Here is my code

setTimeout('loadPHPQuote('+code+')',1000);

Is there anyone who can help me with this please.....?

What exactly is `code`? Can you provide an example? – Felix Kling Jun 19 '12 at 09:35 — Felix Kling, Jun 19 '12 at 09:35

Do this:

setTimeout(function() { loadPHPQuote(code); }, 1000);

When you use quotes, it calls eval behind the scene,
when you need to pass arguments wrap it in a function like above.
To prevent calling function immediately, don't use () in setTimeout or setInterval directly

It is not recommended to pass strings as parameters to setTimeout() (see, e.g., MDN). Use an anonymous function instead:

setTimeout( function(){ loadPHPQuote( code ); }, 1000 );

If you could provide an explanation as to why it's not recommended, it'd be a better answer :) but nonetheless, +1 – Andreas Wong Jun 19 '12 at 09:35

You need you parameter to be in quotes, as it is a string you are passing, e.g.:

setTimeout('loadPHPQuote("'+code+'")',1000);
