Question

I saw this question, and I’m wondering what is the problem with this?

var id = 12;
setTimeout( showGrid ( 'i want to pass variable ' + id + ' here' ), 5000 );

I read the question I’m interested in what the code above is not a good solution. I’ve only Chrome installed, I’ve tried it and it works. Is there any browser issue with it?

Why the anonymous function is better?

Answer 1

You could use a closure:

var id = 12;
setTimeout(function() {
    showGrid('i want to pass variable ' + id + ' here');
}, 5000);

And here’s a live demo.

edit(Milo) from the comments:

the setTimeout function expects a callback or a string variable. You are not passing such thing so your code is invalid. You are directly invoking the showGrid function which is not how it is supposed to work. The showGrid function should be invoked only 5 seconds later.
