js面向对象 实现 tab选项卡效果

代码

function scrollDoor(){
}
scrollDoor.prototype = {
sd : function(menus,divs,openClass,closeClass){
var _this = this;
if(menus.length != divs.length)
{
alert("菜单层数量和内容层数量不一样!");
return false;
}
for(var i = 0 ; i < menus.length ; i++)
{
_this.$(menus[i]).value = i;
_this.$(menus[i]).onmouseover = function(){
//1.先关闭所有的导航和内容：
for(var j = 0 ; j < menus.length ; j++)
{
_this.$(menus[j]).className = closeClass;
_this.$(divs[j]).style.display = "none";
}
//2.打开当前的导航和内容：
//_this.$(menus[this.value]).className = openClass;
this.className = openClass;
_this.$(divs[this.value]).style.display = "block";
}
}
},
$ : function(oid){
if(typeof(oid) == "string")
return document.getElementById(oid);
return oid;
}
}
window.onload = function(){
var SDmodel = new scrollDoor();
SDmodel.sd(["m01","m02"],["c01","c02"],"sd01","sd02");
//SDmodel.sd(["m001","m002"],["c001","c002"],"sd01","sd02");
}
