Color changer

Hi guy’s,

I would like to implement the script below but am not very good with Word Press, please help.

The script changes the input fields color when text has been implemented.

<script>
//Color changer
(function($) {
$(‘.myclass input’).each(function() {
$.data(this, ‘default’, this.value);
}).css(“background-color”,”red”)
.change(function() {
$.data(this, ‘edited’, this.value != “”);
$(this).css(“background-color”,”#ffffff”);
})
})(jQuery);
</script>
