如何用延迟代码将JS各段代码延迟执行

比如以下有该代码：

//【快速增加图标演示目录】
function Add_menuList(){
  var $=function(x){return document.getElementById(x)};
  window.index=0;
  if(typeof(list)!="object"||list.length==0){
    if(confirm("您确定增加图标演示目录吗？")!=true) return;
    window.list = new Array();
    list.push(["00[S]　自定义区-重要目录-系统设置-不可删除","*",duser,"000000"]);
    list.push(["00[A]　演示：设置使用A图标","","","011000"]);
    list.push(["00[B]　演示：设置使用B图标","","","011000"]);
    list.push(["00[C]　演示：设置使用C图标","","","011000"]);
    list.push(["00[D]　演示：设置使用D图标","","","011000"]);
    list.push(["00[E]　演示：设置使用E图标","","","011000"]);
    list.push(["00[H]　演示：设置使用H图标","","","011000"]);
    list.push(["00[M]　演示：默认使用M图标","","","011000"]);
    list.push(["00[N]　演示：上锁可用N图标","","","011000"]);
    list.push(["00[Q]　演示：设置使用Q图标","","","011000"]);
    list.push(["00[V]　演示：设置使用V图标","","","011000"]);
    list.push(["00[X]　演示：设置使用X图标","","","011000"]);
    list.push(["00[Y]　演示：设置使用Y图标","","","011000"]);
    list.push(["00[S]　演示：设置使用S图标","","","011000"]);
  };
  //快速增加目录
  window.Add_MenuList=function(){
    $("dzx").scrollTop= $("sxts").offsetTop-$("dzx").offsetHeight+30;
    if(/目录总数已经超过限定/.test(frxcx.zx.toString())==true){
      alert("目录总数已经达到"+$("menuList").children.length+"个上限！\n\r无法再继续增加网盘目录了！");
      $("frxcx").onreadystatechange=null;window.list=new Array();try{setmenulist()}catch(e){};return;
    };
    if(/√/i.test($("mm4").innerHTML)!=true){
      alert("请登陆管理区后再进行操作！");$("frxcx").onreadystatechange=null;window.list=new Array();return;
    };
    if(index < list.length){
      var M=$("menuList").children.length;var x="00"+(M+1);x=x.substr(x.length-2);var A=list[index];
      $("frxcx").onreadystatechange=function(){if(this.readyState=="complete"){setTimeout("Add_MenuList()",200)}};//绑定事件
      readxml("xzml",A[0].replace(/^(\d{2})/,x), (A[1]?A[1]:""), (A[2]?A[2]:""), (A[3]?A[3]:"")); index++;
    }else{
      window.list=new Array();//请空数组
      $("frxcx").onreadystatechange=null;
      try{setmenulist()}catch(e){};//设置目录图标
    }
  };
  Add_MenuList();
};
Add_menuList()

如何让下面的命令每个代码之间延迟2秒执行啊，是代码与代码之间延迟：
list.push(["00[S]　自定义区-重要目录-系统设置-不可删除","*",duser,"000000"]);
    list.push(["00[A]　演示：设置使用A图标","","","011000"]);
    list.push(["00[B]　演示：设置使用B图标","","","011000"]);
    list.push(["00[C]　演示：设置使用C图标","","","011000"]);
    list.push(["00[D]　演示：设置使用D图标","","","011000"]);
    list.push(["00[E]　演示：设置使用E图标","","","011000"]);
    list.push(["00[H]　演示：设置使用H图标","","","011000"]);
    list.push(["00[M]　演示：默认使用M图标","","","011000"]);
    list.push(["00[N]　演示：上锁可用N图标","","","011000"]);
    list.push(["00[Q]　演示：设置使用Q图标","","","011000"]);
    list.push(["00[V]　演示：设置使用V图标","","","011000"]);
    list.push(["00[X]　演示：设置使用X图标","","","011000"]);
    list.push(["00[Y]　演示：设置使用Y图标","","","011000"]);
    list.push(["00[S]　演示：设置使用S图标","","","011000"]);
