你一开始就应该把问题说清楚，获取了json数据，需要展示easyui的datagrid里。
如果时展示在datagrid里，都不需要循环，直接返回这个json就行了
官网有例子，就连json数据都给你打包好了，如果格式不符合返回的数据，你后台就要先解析处理数据，然后再打包成json数据。这里我就不写代码了。
var obj = data.parseJSON(); //由JSON字符串转换为对象
在js中用for循环遍历,先获取到result中的值然后这样
for ( var i = 0; i < result.length; i++){
console.log( result[i] );
}
console.log(result[i]); 打印出来的数据是你对应的单个对象
是easyui下拉框填充省份嘛？身份数据后台获取。
例子：
页面代码：<td><input name="religionType" id="religionType" />
<script type="text/javascript">
$(function() {
//宗教信仰
$("#religionType").combobox({
width: 135,
editable: false,
url: "caSysDictController.do?getDictList&dictCode=ZJXY",
valueField: 'id', //id
textField: 'dictName' //对应名称
});
});
</script>
后台方法：
@RequestMapping(params = "getDictList")
@ResponseBody
public List<CaSysDict> getDictList(HttpServletRequest request) {
String dictCode = request.getParameter("dictCode");
return caSysDictService.getDictListByKey(dictCode); //查询数据
}
具体看我博客：https://blog.csdn.net/qq_23126581/article/details/82345652
是后台遍历还是前台遍历？
1、JsonObject
使用JsonObject解析只有一条数据的json是非常方便的例如："{\"name\":\"zhangsan\",\"password\":\"zhangsan123\",\"email\":\"10371443@qq.com\"}"
public static void main(String[] args) {
String jsonString ="{\"name\":\"zhangsan\",\"password\":\"zhangsan123\",\"email\":\"10371443@qq.com\"}";
JSONObject json = JSONObject.fromObject(jsonString);
User user = new User();
user.setName(json.getString("name"));
user.setPassword(json.getString("password"));
user.setEmail(json.getString("email"));
System.out.println(user.toString());
}
2、JsonArray
使用JsonArray解析数组数据的json是非常方便的例如："[{\"name\":\"zhangsan\",\"password\":\"zhangsan123\",\"email\":\"10371443@qq.com\"},{\"name\":\"lisi\",\"password\":\"lisi123\",\"email\":\"1435123@qq.com\"}]"
[java] view plain copy
String json = <span style="color: rgb(51, 51, 51); font-family: Arial; font-size: 14px; line-height: 26px;">"[{\"name\":\"zhangsan\",\"password\":\"zhangsan123\",\"email\":\"10371443@qq.com\"},</span><span style="color: rgb(51, 51, 51); font-family: Arial; font-size: 14px; line-height: 26px;">{\"name\":\"lisi\",\"password\":\"lisi123\",\"email\":\"1435123@qq.com\"}</span><span style="color: rgb(51, 51, 51); font-family: Arial; font-size: 14px; line-height: 26px;">]"</span>;
JSONArray jsonArray = JSONArray.fromObject(json);
ArrayList<User> users = new ArrayList<User>();
for (int i = 0; i < jsonArray.size(); i++) {
User userM = new User();
user.setName(jsonArray.getJSONObject(i).getString("name"));
user.setpassword(jsonArray.getJSONObject(i).getString("password"));
user.setEmail(jsonArray.getJSONObject(i).getString("email"));
users.add(user);
}
for (User user : users) {
System.out.println(user.toString());
}
二、Jsp解析json数据
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>JqueryDemo1</title>
<script src="jquery.js"></script>
<script>
function showData() {
var str='{ "name": "John" }';//json标准格式
var obj = eval('(' + str + ')');
alert( obj.name);
var str2="{ 'name': 'John' }";
var obj2 = eval('(' + str2 + ')');
alert( obj2.name);
var str3='{"GetUserPostByIdResult":{"Age":"33","ID":"2server","Name":"mady"}}';
var obj3 = eval('(' + str3 + ')');
alert( obj3.GetUserPostByIdResult.ID);
var data=" { root: [ {'name':'6200','value':'0'}, {'name':'6101','value':'xa'}, {'name':'6102','value':'beijing'}, {'name':'6103','value':'haerbin'}]}";
var date1=eval('('+data+')');
alert(date1.root[2].name);
var last=JSON.stringify(obj);//将JSON对象转化为JSON字符
alert(last);
}
</script>
</head>
<body>
<input id="Button1" type="button" value="Hit Me" onclick="showData()" />
</body>
</html>
前台解析差不多就是这样，你试试
先解析json
比如你用var str=你返回的数据
然后解析：var obj = eval('(' + str + ')');
for(int i=0;i<obj.result.length;i++)
{
alert(result[i].city);
}
差不多就是这样，你试试
首先，你的数据是在返回的result中的，所以你先把这个字段取出来，来循环这个数组，假设将结果赋值为data,便利如下。
data.map((item, index) => {
//再次拼接字符串
}
