这次给大家带来使用JS接收List
1、页面js代码:
var idList = new Array(); idList.push(“1”); idList.push(“2”); idList.push(“3”); var isBatch = false; $.ajax({ type: "POST", url: "<%=path%>/catalog.do?fn=deleteCatalogSchemes", dataType: 'json', data: {"idList":idList,"isBatch":isBatch}, success: function(data){ … }, error: function(res){ … } });
2、Controller方法:
@Controller @RequestMapping("/catalog.do") public class CatalogController { @RequestMapping(params = "fn=deleteCatalogSchemes") @ResponseBody public AjaxJson deleteCatalogSchemes(@RequestParam("idList[]") List<String> idList,Boolean isBatch) { … } }
接收List
1、User实体类:
public class User { private String name; private String pwd; //省略getter/setter }
2、页面js代码:
var userList = new Array(); userList.push({name: "李四",pwd: "123"}); userList.push({name: "张三",pwd: "332"}); $.ajax({ type: "POST", url: "<%=path%>/catalog.do?fn=saveUsers", data: JSON.stringify(userList),//将对象序列化成JSON字符串 dataType:"json", contentType : 'application/json;charset=utf-8', //设置请求头信息 success: function(data){ … }, error: function(res){ … } });
3、Controller方法:
@Controller @RequestMapping("/catalog.do") public class CatalogController { @RequestMapping(params = "fn=saveUsers") @ResponseBody public AjaxJson saveUsers(@RequestBody List<User> userList) { … } }
如果想要接收User[]数组,只需要把saveUsers的参数类型改为@RequestBody User[] userArray就行了。
接收List
1、页面js代码(不需要User对象了):
var userList = new Array(); userList.push({name: "李四",pwd: "123"}); userList.push({name: "张三",pwd: "332"}); $.ajax({ type: "POST", url: "<%=path%>/catalog.do?fn=saveUsers", data: JSON.stringify(userList),//将对象序列化成JSON字符串 dataType:"json", contentType : 'application/json;charset=utf-8', //设置请求头信息 success: function(data){ … }, error: function(res){ … } });
2、Controller方法:
@Controller @RequestMapping("/catalog.do") public class CatalogController { @RequestMapping(params = "fn=saveUsers") @ResponseBody public AjaxJson saveUsers(@RequestBody List<Map<String,Object>> listMap) { … } }
接收User(bean里面包含List)集合参数:
1、User实体类:
public class User { private String name; private String pwd; private List<User> customers;//属于用户的客户群 //省略getter/setter }
2、页面js代码:
var customerArray = new Array(); customerArray.push({name: "李四",pwd: "123"}); customerArray.push({name: "张三",pwd: "332"}); var user = {}; user.name = "李刚"; user.pwd = "888"; user. customers = customerArray; $.ajax({ type: "POST", url: "<%=path%>/catalog.do?fn=saveUsers", data: JSON.stringify(user),//将对象序列化成JSON字符串 dataType:"json", contentType : 'application/json;charset=utf-8', //设置请求头信息 success: function(data){ … }, error: function(res){ … } });
3、Controller方法:
@Controller @RequestMapping("/catalog.do") public class CatalogController { @RequestMapping(params = "fn=saveUsers") @ResponseBody public AjaxJson saveUsers(@RequestBody User user) { List<User> customers = user.getCustomers(); … } }
