Question

I’m trying to write some jquery that will go through a specified unordered list / dom element and assign a CSS (animation) class to each list item / child. I also want to make an adjustable delay time between the .addClass.

Everything I’ve tried has failed miserably.

For example:

<ul>
   <li>Item 1</li>
   <li>Item 2</li>
   <li>Item 3</li>
   <li>Item 4</li>
</ul>

Becomes:

<ul>
   <li class="animation">Item 1</li>
     (50ms delay)
   <li class="animation">Item 2</li>
     (50ms delay)
   <li class="animation">Item 3</li>
     (50ms delay)
   <li class="animation">Item 4</li>
     (50ms delay)
</ul>

Any thoughts?

This here works:

$('ul li').each(function(i){
    var t = $(this);
    setTimeout(function(){ t.addClass('animation'); }, (i+1) * 50);
});
