今天我们用JS的方法写一下这些常用的函数,使它们使用起来更加方便:
标记当前 function cur(ele,cls){} 接受两个函数 一个是ele 要标记的元素 或者 一个选择符,cls是标记的类名 一个css class 默认为"cur";
选项卡 function tab(idtab,tagtab,idcon,tagcon,act,cls,idx){} 接受的参数比较多
idtab:控制触发选项卡的容器
idtag:控制触发选项卡的标签
idcon:被控制的内容容器idtag:被控制的内容标签act: 触发方式 默认为 onclick
cls:标记当前的css class 默认为 “cur”
idx:默认显示第几项 默认为0 首项

函数如下:
function cur(ele,cls){
return new cur.prototype.init(ele,cls);
}
cur.prototype={
init:function(ele,cls){
this.idx=0;
this.mark= cls? " "+cls:"cur";
this.ele= typeof ele=="object"? ele:document.getElementById(ele);
this.hdlr.call(this);
return this.idx;
},
hdlr:function(){
this.addCls();
this.rmvCls();
},
addCls:function(){
this.ele.className+=this.mark;
},
rmvCls:function(){
var itm=this.ele;
var prn=itm.parentNode;
var itms=prn.getElementsByTagName(itm.nodeName);
for(i=0; i<itms.length; i++){
if(itms[i]!==itm){
itms[i].className=itms[i].className.replace(this.mark,"");
}else{
this.idx=i;
}
}
}
}
cur.prototype.init.prototype=cur.prototype;
function tab(idtab,tagtab,idcon,tagcon,act,cls,idx){
return new tab.prototype.init(idtab,tagtab,idcon,tagcon,act,cls,idx);

this.contag=this.conid.getElementsByTagName(tagcon);
this.cls=cls || "cur";
this.act=act || "onclick";
this.idx=idx || 0;
