EasyUI框架 使用Ajax提交注冊信息的實現代碼
一、服務器代碼：
@Controller
@Scope("prototype")
public class StudentAction extends BaseAction<Student> {
private static final long serialVersionUID = -2612140283476148779L;
private Logger logger = Logger.getLogger(StudentAction.class);
private String rows;// 每頁顯示的記錄數
private String page;// 當前第幾頁
private Map<String, Object> josnMap = new HashMap<>();
// 查詢出所有學生信息
public String list() throws Exception {
return "list";
}
public String regUI() throws Exception {
return "regUI";
}
// 查詢出所有學生信息
public String listContent() throws Exception {
List<Student> list = studentService.getStudentList(page, rows);
System.out.println("list==" + list);
toBeJson(list, studentService.getStudentTotal());
return "toJson";
}
// 轉化為Json格式
public void toBeJson(List<Student> list, int total) throws Exception {
josnMap.put("total", total);
josnMap.put("rows", list);
JSONParser.writeJson(josnMap);// 自定義的工具類
}
public String reg(){
logger.error("kkk");
try {
studentService.save(model);
josnMap.put("success", true);
josnMap.put("msg", "注冊成功!");
} catch (Exception e) {
e.printStackTrace();
josnMap.put("success", false);
josnMap.put("msg", "注冊失敗!");
}
try {
ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");
ServletActionContext.getResponse().setCharacterEncoding("utf-8");
ServletActionContext.getResponse().getWriter().print(JSON.toJSONString(josnMap));
} catch (IOException e) {
e.printStackTrace();
}
return "toJson";
}
public void setRows(String rows) {
this.rows = rows;
}
public void setPage(String page) {
this.page = page;
}
public Map<String, Object> getJosnMap() {
return josnMap;
}
public void setJosnMap(Map<String, Object> josnMap) {
this.josnMap = josnMap;
}
}
二、BaseAction代碼：
import java.lang.reflect.ParameterizedType;
import javax.annotation.Resource;
import org.apache.struts2.ServletActionContext;
import cn.oppo.oa.service.DepartmentService;
import cn.oppo.oa.service.ForumService;
import cn.oppo.oa.service.PrivilegeService;
import cn.oppo.oa.service.RoleService;
import cn.oppo.oa.service.StudentService;
import cn.oppo.oa.service.UserService;
import com.alibaba.fastjson.JSON;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
public abstract class BaseAction<T> extends ActionSupport implements ModelDriven<T> {
/**
*
*/
private static final long serialVersionUID = 1L;
@Resource
protected RoleService roleService;
@Resource
protected DepartmentService departmentService;
@Resource
protected UserService userService;
@Resource
protected PrivilegeService privilegeService;
@Resource
protected ForumService forumService;
@Resource
protected StudentService studentService;
protected T model;
@SuppressWarnings("unchecked")
public BaseAction() {
try {
// 得到model的類型信息
ParameterizedType pt = (ParameterizedType) this.getClass().getGenericSuperclass();
Class<T> clazz = (Class<T>) pt.getActualTypeArguments()[0];
// 通過反射生成model的實例
model = (T) clazz.newInstance();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
public void writeJson(Object object){
try {
String json = JSON.toJSONStringWithDateFormat(object, "yyyy-MM-dd HH:mm:ss");
ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");
ServletActionContext.getResponse().setCharacterEncoding("utf-8");
ServletActionContext.getResponse().getWriter().write(json);
ServletActionContext.getResponse().getWriter().flush();
ServletActionContext.getResponse().getWriter().close();
} catch (Exception e) {
e.printStackTrace();
}
}
public T getModel() {
return model;
}
}
三、頁面代碼：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
<title>EasyUI框架</title>
<%@ include file="/WEB-INF/jsp/public/common.jspf" %>
<script type="text/javascript">
$(function(){
if(${"#easyui_regForm"}.form('validate')){
$.ajax({
url:'${pageContext.request.contextPath}/student_reg.action',
data:${"#easyui_regForm"}.serialize(),
dataType:'json',
success:function(obj,status,jqXHR){
if(obj.success){
$("#easyui_regDialog").dialog('close');
}
$.message.show({
title:'提示',
msg:obj.msg
});
}
});
}else{
alert('驗證失敗');
}
});
</script>
</head>
<body class="easyui-layout">
<div data-options="region:'north',split:true" >aa</div>
<!-- <div data-options="region:'south',split:true" >bb</div>-->
<div data-options="region:'east',title:'East',split:true" >cc</div>
<div data-options="region:'west',title:'West',split:true" >dd</div>
<div data-options="region:'center',title:'center title'" >kk</div>
<div class="easyui-dialog" data-options="title:'登陸', modal:true,
closable:false,

$('#easyui_regForm input').val('');
$('#easyui_regDialog').dialog('open');
}
}]" >
<table>
<tr>
<td>登陸名稱：</td>
<td><input type="text" name="name"/></td>
</tr>
<tr>
<td>登陸密碼：</td>
<td><input type="password" name="password"/></td>
</tr>
</table>
</div>
<div id="easyui_regDialog" class="easyui-dialog" data-options="title:'注冊', modal:true,
closable:true,
closed:true,
buttons:[{
text:'注冊',
handler:function(){
$('#easyui_regForm').form('submit',{
url : '${pageContext.request.contextPath}/student_reg.action',

var obj = jQuery.parseJSON(data);
if (obj.success) {

}
$.messager.show({

}
});
}
},{
text:'取消',
handler:function(){alert('注冊')}
}]" >
<form id="easyui_regForm" method="post">
<table>
<tr>
<td>登陸名稱：</td>
<td><input type="text" name="loginName" class="easyui-validatebox" data-options="required:true,missingMessage:'用戶名稱不能為空'"/></td>
</tr>
<tr>
<td>登陸密碼：</td>

</table>
</form>
</div>
</body>
</html>
四、struts2.xml配置
