//The prompt box is always in the lower right corner
rePosition: function(_this) {
        var divHeight = parseInt(_this.eMsg.offsetHeight, 10);
        var divWidth = parseInt(_this.eMsg.offsetWidth, 10);
        var docWidth = document.body.clientWidth;
        var docHeight = document.body.clientHeight;
​ ​ _this.eMsg.style.top = docHeight - divHeight parseInt(document.body.scrollTop, 10);
​ ​ _this.eMsg.style.left = docWidth - divWidth parseInt(document.body.scrollLeft, 10);
},

//The prompt box slowly rises
MoveDiv: function(_this) {
          /*
​​​​Here you can set it to automatically close after a few seconds
...
*/
         try {
If (parseInt(_this.eMsg.style.top, 10) <= (_this.docHeight - _this.divHeight parseInt(document.body.scrollTop, 10))) {
                   window.clearInterval(_this.objTimer);
                  _this.objTimer = window.setInterval(function() { _this.rePosition(_this); }, 1);
            }
​​​​​​​ _this.divTop = parseInt(_this.eMsg.style.top, 10);
​​​​​​ _this.eMsg.style.top = _this.divTop - 1;
}
         catch (e) {
}
},
 
//Close the prompt box
Close: function() {
This.eMsg.style.visibility = 'hidden';
If (this.objTimer) window.clearInterval(this.objTimer);
},

//Show prompt box
show: function() {
        var divTop = parseInt(this.eMsg.style.top, 10);
This.divTop = divTop;
        var divLeft = parseInt(this.eMsg.style.left, 10);

var divHeight = parseInt(this.eMsg.offsetHeight, 10);
This.divHeight = divHeight;

var divWidth = parseInt(this.eMsg.offsetWidth, 10);
        var docWidth = document.body.clientWidth;
        var docHeight = document.body.clientHeight;
This.docHeight = docHeight;

this.eMsg.style.top = parseInt(document.body.scrollTop, 10) docHeight 10;
This.eMsg.style.left = parseInt(document.body.scrollLeft, 10) docWidth - divWidth;
This.eMsg.style.visibility = "visible";

var _this = this;
This.objTimer = window.setInterval(function() { _this.moveDiv(_this); }, 10);
}
}

var msgTip = new messageTip({ name: 'eMeng' });
window.onload = function() { msgTip.show(); };
window.onresize = function() { msgTip.rePosition(msgTip); };
