JS+DIV實現自訂Title的顯示方式

     自訂的title顯示方式一直在華夏用，當你的滑鼠移至上方在帶有提示的連結上時會有自訂的顯示內容出現，顯示的內容支援html代碼，但是這個效果不支援firefox及其他瀏覽器，最近對之進行了改進，終於相容了FF，Safari。代碼如下：

 var qTipTag = "a"; //Which tag do you want to qTip-ize? Keep it lowercase!//
var qTipX = -30; //This is qTip's X offset//
var qTipY = 25; //This is qTip's Y offset// //There's No need to edit anything below this line//
tooltip = {
  name : "qTip",
  offsetX : qTipX,
  offsetY : qTipY,
  tip : null
}tooltip.init = function () {
 var tipNameSpaceURI = "http://www.w3.org/1999/xhtml";
 if(!tipContainerID){ var tipContainerID = "qTip";}
 var tipContainer = document.getElementById(tipContainerID); if(!tipContainer) {
   tipContainer = document.createElementNS ? document.createElementNS(tipNameSpaceURI, "div") : document.createElement("div");
  tipContainer.setAttribute("id", tipContainerID);
   document.getElementsByTagName("body").item(0).appendChild(tipContainer);
 } if (!document.getElementById) return;
 this.tip = document.getElementById (this.name);
 if (this.tip) document.onmousemove = function (evt) {tooltip.move (evt)}; var a, sTitle;
 var anchors = document.getElementsByTagName (qTipTag); for (var i = 0; i < anchors.length; i ++) {
  a = anchors[i];
  sTitle = a.getAttribute("title");
  if(sTitle) {
   a.setAttribute("tiptitle", sTitle);
   a.removeAttribute("title");
   a.onmouseover = function() {tooltip.show(this.getAttribute('tiptitle'))};
   a.onmouseout = function() {tooltip.hide()};
  }
 }
}tooltip.move = function (evt) {
 var x=0, y=0;
 if (document.all) {//IE
  x = (document.documentElement && document.documentElement.scrollLeft) ? document.documentElement.scrollLeft : document.body.scrollLeft;
  y = (document.documentElement && document.documentElement.scrollTop) ? document.documentElement.scrollTop : document.body.scrollTop;
  x += window.event.clientX;
  y += window.event.clientY;
  
 } else {//Good Browsers
  x = evt.pageX;
  y = evt.pageY;
 }
 this.tip.style.left = (x + this.offsetX) + "px";
 this.tip.style.top = (y + this.offsetY) + "px";
}tooltip.show = function (text) {
 if (!this.tip) return;
 this.tip.innerHTML = text;
 this.tip.style.display = "block";
}tooltip.hide = function () {
 if (!this.tip) return;
 this.tip.innerHTML = "";
 this.tip.style.display = "none";
}window.onload = function () {
 tooltip.init ();
} css樣式：/*tip div*/
div#qTip{
  border: 1px solid #99CC33;
  border-right-width: 2px;
  border-bottom-width: 2px;
  display: none;
  background: #fff;
  color: #000;
  font: 13px Verdana, Arial, Helvetica, sans-serif;
  text-align: left;
  position: absolute;
  z-index: 1000;
  padding: 8px;
