Question

I am trying to write a function that applies an action through all <strong> elements, and when finishes with one, applies it to the next one.

Also, at the end, it must start again with the first <strong>.

I am sure I remember reading about a jquery function for doing this, but I cannot remember it.

For it to infinitely loop, you’ll need to use something like setInterval() so it doesn’t block other javascript from executing.

I assume that’s what you mean when you say “Also, at the end, it must start again with the first again.”

Here’s an example: http://jsfiddle.net/34sFN/

Another example, somewhat based on your comment: http://jsfiddle.net/34sFN/1/

var $ems = $('em');

// Loops through all your elements every 100 milliseconds.
// Change the duration to suit.
setInterval(function() {
    $ems.each(function() {
        // Do something to the current EM using $(this)
    });
},100);
