生活随笔
收集整理的這篇文章主要介紹了
自定mvc之新增，下架以及上架
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
一.下拉框
1.下拉框的實體類
package com.zy.entity;public class Category {private long id;private String name;public long getId() {return id;}public void setId(long id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public Category() {// TODO Auto-generated constructor stub}public Category(long id, String name) {super();this.id = id;this.name = name;}@Overridepublic String toString() {return "Category [id=" + id + ", name=" + name + "]";}}2.dao方法
package com.zy.dao;import java.util.List;import com.zking.util.BaseDao; import com.zking.util.PageBean; import com.zy.entity.Category;public class CategoryDao extends BaseDao<Category> {public List<Category> list(Category category, PageBean pageBean) throws Exception {// TODO Auto-generated method stubString sql="select * from t_easyui_category";return super.executeQuery(sql, Category.class, pageBean);}}3.CategoryAction?
package com.zy.web;import java.util.List;import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;import com.zking.framework.ActionSupport; import com.zking.framework.ModelDriver; import com.zking.util.ResponseUtil; import com.zy.dao.CategoryDao; import com.zy.entity.Category;public class CategoryAction extends ActionSupport implements ModelDriver<Category>{ private Category category=new Category(); private CategoryDao categoryDao =new CategoryDao();@Overridepublic Category getModel() {// TODO Auto-generated method stubreturn category;}/*** 加載書籍類別下拉框* @param req* @param resp* @return*/public String combobox(HttpServletRequest req, HttpServletResponse resp) {try {List<Category> list = categoryDao.list(category,null);ResponseUtil.writeJson(resp, list);} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}return null;} }4.配置mvc文件
<action path="/category" type="com.zy.web.CategoryAction"></action>5.添加下拉框組
<input id="cid" name="cid" value="" label="類別" >? $(function () {
? ? ?? ?$('#cid').combobox({ ? ?
? ? ?? ? ? ?url:'${pageContext.request.contextPath}/category.action?methodName=combobox', ? ?
? ? ?? ? ? ?valueField:'id', ? ?
? ? ?? ? ? ?textField:'name' ??
? ? ?? ?});?
? ? });

?二.新增，下架與上架
?1.增加書籍的jsp

<action path="/book" type="com.zy.web.BookAction">
?? ?</action>
?6.新增js
function submitForm() {$('#ff').form('submit', {url:'${pageContext.request.contextPath}/book.action?methodName=add',success: function(data){if(data ==1){ //新增完清空數據$('#ff').form('clear')}}});}function clearForm() {$('#ff').form('clear');}7.書籍上架的js
function shangjia() {$.messager.confirm('確認','您確認想要上架此書籍嗎？',function(r){if (r){var row = $('#dg').datagrid('getSelected');if (row){$.ajax({url:'${pageContext.request.contextPath}/book.action?methodName=editStatus&state=2&id=' + row.id,success:function (data) {}})} }});}8.下架的js
function xiajia() {$.messager.confirm('確認','您確認想要下架此書籍嗎？',function(r){if (r){var row = $('#dg').datagrid('getSelected');if (row){$.ajax({url:'${pageContext.request.contextPath}/book.action?methodName=editStatus&state=3&id=' + row.id,success:function (data) {$('#dg').datagrid('reload');}})}}});}9.項目所需要的jar包
