jQuery(document).ready(function() {
  jQuery.fn.cleardefault = function() {
  return this.focus(function() {
    if( this.value == this.defaultValue ) {
      this.value = "";
    }
  }).blur(function() {
    if( !this.value.length ) {
      this.value = this.defaultValue;
    }
  });
};
jQuery("input, textarea").cleardefault();

});
