1、頁面js代碼：
Js代碼
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：
java代碼
@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<User>、User[]集合參數(shù)：
1、User實體類：
Java代碼
public class User { private String name; private String pwd; //省略getter/setter }
2、頁面js代碼：
Js代碼var userList = new Array(); userList.push({name: "李四",pwd: "123"}); userList.push({name: "張三",pwd: "332"}); $.ajax({ type: "POST", url: "<%=path%>/catalog.do?fn=saveUsers", data: JSON.stringify(userList),//將對象序列化成JSON字符串 dataType:"json", contentType : 'application/json;charset=utf-8', //設(shè)置請求頭信息 success: function(data){ … }, error: function(res){ … } });
3、Controller方法：
Java代碼@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[]數(shù)組，只需要把saveUsers的參數(shù)類型改為@RequestBody User[] userArray就行了。
接收List<Map<String,Object>>集合參數(shù)：
1、頁面js代碼（不需要User對象了）：
Js代碼var userList = new Array(); userList.push({name: "李四",pwd: "123"}); userList.push({name: "張三",pwd: "332"}); $.ajax({ type: "POST", url: "<%=path%>/catalog.do?fn=saveUsers", data: JSON.stringify(userList),//將對象序列化成JSON字符串 dataType:"json", contentType : 'application/json;charset=utf-8', //設(shè)置請求頭信息 success: function(data){ … }, error: function(res){ … } });
2、Controller方法：
Java代碼@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)集合參數(shù)：
1、User實體類：
Java代碼public class User { private String name; private String pwd; private List<User> customers;//屬于用戶的客戶群 //省略getter/setter }
2、頁面js代碼：
Js代碼
var customerArray = new Array(); customerArray.push({name: "李四",pwd: "123"}); customerArray.push({name: "張三",pwd: "332"}); var user = {}; user.name = "李剛"; user.pwd = "888"; user. customers = customerArray; $.ajax({ type: "POST", url: "<%=path%>/catalog.do?fn=saveUsers", data: JSON.stringify(user),//將對象序列化成JSON字符串 dataType:"json", contentType : 'application/json;charset=utf-8', //設(shè)置請求頭信息 success: function(data){ … }, error: function(res){ … } }); 3、Controller方法：
Java代碼@Controller @RequestMapping("/catalog.do") public class CatalogController { @RequestMapping(params = "fn=saveUsers") @ResponseBody public AjaxJson saveUsers(@RequestBody User user) { List<User> customers = user.getCustomers(); … } } 新聞熱點
