How to use a variable in jQuery?

Question

How to use variable in jQuery? I used the var i, Here's the code:

var i=0;
for (i=0;i<=5;i++){
   $('.slide:eq(i)').delay(3000).fadeOut(500);
}

Thank you.

It doesn't "work" because it's treated like a plain string.

You need to concatenate with '+'.

$('.slide:eq('+i+')').delay(3000).fadeOut(500);

You can also use:

$('.slide').eq(i).delay(3000).fadeOut(500);

which is clearer.
