恩恩，一个想法，初步实现了它～就剩封装了

var US = {};
US.randomId = function(){
var word = ['a','b','c','d','e','f','g'];
var num = [1,2,3,4,5,6,7,8,9,0];
var result = '';
//16位iD
while(result.length<16){
var wordRandom = Base.Number.random4Int(0-word.length,word.length-1);
var numRandom = Base.Number.random4Int(0-num.length,num.length-1)
if(wordRandom>=0){
result += word[wordRandom];
}
if(numRandom>=0){
result += num[numRandom];
}
}
return result;
}

var map = {};
window.onload = function(){
var names = document.getElementsByName("showed");
for(var i= 0,len=names.length;i<len;i++){
var _map = {};
_map['id'] = names[i].id = US.randomId();
var htmlObj = document.getElementById(_map['id']);
var itemsName = null ,itemsId=null;
for(var j= 0,len_ = htmlObj.attributes.length;j<len_;j++){
if(htmlObj.attributes[j].nodeName=='itemsname'){
itemsName =htmlObj.attributes[j].value;
continue;
}
if(htmlObj.attributes[j].nodeName=='itemsid'){
itemsId =htmlObj.attributes[j].value;
continue;
}
if(itemsName!=null&&itemsId!=null){
break;
}
}
_map['itemsname'] = itemsName;
map[itemsId] = _map;
}
console.log(map);
document.getElementById(map['one'].id).value='one Text...';
console.log(document.getElementById(map['one'].id).value)
}
