Question

How can I change a word every 2-3 seconds using jQuery?

For example:

I have this:

    <         


        
      

Answer 1

(function(){

    // List your words here:
    var words = [
        'awesome',
        'incredible',
        'cool',
        'fantastic'
        ], i = 0;

    setInterval(function(){
        $('#changerificwordspanid').fadeOut(function(){
            $(this).html(words[i=(i+1)%words.length]).fadeIn();
        });
       // 2 seconds
    }, 2000);

})();

Give your span an id, and change changerificwordspanid to the id of the span.
