用数组
<Script Language ="JavaScript">
var arrList = [];
for(var i=0;i < 10; i++){
 arrList[i] = "data" + i;
}
alert(arrList);
var arrMap = [];
arrMap["name1"] = "data1";
arrMap["name2"] = "data2";
arrMap["name3"] = "data3";
for(o in arrMap){
  alert(arrMap[o]);
}
</Script>

和list一样
    var list=[
        {"name":"A","Id":1},
        {"name":"B","Id":2},
        {"name":"C","Id":3}
    ];
    alert(list[0]["Id"]);
    alert(list[0]["name"]);

  var selIndex = document.getElementById(obj).selectedIndex;
  var mes="";
var fullList = document.getElementById(obj).fullList;
  alert(!fullList);
  if(!fullList){
     fullList=new Array();
     for(i=0;i<document.getElementById(obj).options.length;i++){
      var item = new Object();
      var key=document.getElementById(obj).options[i].value;
      var val=document.getElementById(obj).options[i].innerHTML;
      item[key]=val;
      fullList.push(item);
      }
  }
 if(fullList!=null){
     for(i=0;i<fullList.length;i++){
       for(var p in fullList[i]){
          alert(fullList[i][p]);
