后臺方法：
1 JSONArray json = new JSONArray();
2 String pareId = request.getParameter("dicId");
3 List list = zhidaoBO.getQuestionTDicByParentId(pareId);//返回一個list
4 json = JSONArray.fromObject(list);
5 return super.ajaxReturnJSON(request, response, json.toString());
頁面接收到的結(jié)果：
[["402881c2219417340121945dd7d10008","瑜伽","zYoga"],
["402881c2219417340121945eeb730009","有氧健身操","zAerobicGym"]]
然后在回調(diào)函數(shù)里用js去操作
1 $.post("<c:url value='/user/zhidao/do.ao?method=getChildClass'/>",
2 {"dicId":id},
3 function(json){
4 json=eval('('+json+')');
5 var obj = $("#childSelect");
6 obj.empty();
7 for(var i=0;i<json.length;i++){
8 //obj.append(<option value='" + json[i][0] + "'
onclick='optionSelect(""" + json[i][0] + """)'>" + json[i][1] + "</option>");
9 obj.append("<option value='" + json[i][0] + "'>" + json[i][1] + "</option>");
10 }
11 });
