首先要用JSONArray ja = JSONArray.fromObject(list);封装,然后PrintWriterout=response.getWriter();out.print(ja);
out.flush();
out.close();写出
这时候在js里面var text = xmlHttp.responseText; //字符串(json格式的)
var obj = JSON.parse(text);
var array = obj.list; //数组[存放若干个js对象
for(var i=0;i<array.length;i++){
var e = array[i];
var id = e.Id;
var name = e.name;
}
回调函数，jquery的ajax，可以直接each
怎么取到ajax遍历对象集合后的第一个对象
