Question

The script below applies random colours from an array to a div id, and changes the colours on hover. I would like to amend it so that it loops through a div class and applies random colours to all classes on a page. Obviously the click functions would have to be done by id, but I imagine there is a way of looping through the div classes such that they all have different random colours which change on hover.

Could someone help with this?

Thanks

$(document).ready(function() {
  var test = $("#example").text().split('');

    var normal = generateColors(test);
    var hover = generateColors(test);
    $("#example").html(normal);

    $("#example").hover( 
      function(event) { $("#example").html(hover) }, 
      function(event) { $("#example").html(normal) });

    $("#example").click(function() { 
    location.href = "http://www.google.co.uk"; 
    });

});

function generateColors(characters) {
    var result = "";
    var i = 0;
    for(i=0; i < characters.length; i++) {
        result += "<span style='color:"+getColor()+"'>"+characters[i]+"</span>";
    }

   return result;
}        

function getColor() {
    var colList = ['#7EA404', '#14AFB0','#B05718', '#B0A914', '#B01617','#902BB0', '#B003A2', '#4A429C','#33821E', '#226795', '#D0B600','#886833'];

    var i = Math.floor((Math.random()*colList.length));
  return colList[i];
}

To apply the colors, and store them on the different elements, you could do:

$(".example").each(function() {
    var text = $(this).text().split(''),
        normal = generateColors(text),
        hover = generateColors(text);

    $(this).html(normal).data('hover', hover).data('normal', normal);
});

$(".example").hover( 
    function() {
        $(this).html($(this).data('hover'));
    }, 
    function() { 
        $(this).html($(this).data('normal'));
});

Setting each link with location.href on click seems like a really bad idea, but up to you.
