js 类中写onmousedown，高手请看

打算写一个移动层的类，发现在类里面无法执行层的onmousedown,up,等事件

function movediv(divName,divTitle){
this.div = document.getElementById(divName);
this.tit = document.getElementById(divTitle);

this.t = 0;
this.l = 0;
this.tn = 0;

this.onMouseDown = function(){
this.div.setCapture();
this.l = event.x - this.tit.style.pixelLeft;
this.t = event.y - this.tit.style.pixelTop;
this.tit.attachEvent("onmousemove",this.onMouseMove)
}
this.onMouseMove = function(){
alert(this.tit);
this.tit.style.left = event.x-this.l;
this.tit.style.top = event.x-this.t;
}
this.onMouseUp = function(){
this.tit.releseCapture();
this.tit.attachEvent("onmousemove",this.onMouseMove)
}

this.tit.attachEvent("onmousedown",this.onMouseDown)
this.tit.attachEvent("onmouseup",this.onMouseUp)
}
