一、新增頁面書籍類別下拉框加載

根據下拉框類型寫實體類

?查詢所有類型的方法

public class CategoryDao extends BaseDao<Category>{
? ??
? ? public List<Category> list(Category category, PageBean pageBean) throws Exception {
? ? ? ? String sql="select * from t_easyui_category ";
? ? ? ? return super.executeQuery(sql, Category.class, pageBean);
? ? }

}

?子控制器

package lxy.com.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.lxy.util.ResponseUtil;import lxy.com.dao.CategoryDao; import lxy.com.entity.Category;public class CategoryAction extends ActionSupport implements ModelDriver<Category>{private Category category=new Category();private CategoryDao cd=new CategoryDao();@Overridepublic Category getModel() {return category;}// 書籍類別下拉框public String combobox(HttpServletRequest req, HttpServletResponse resp) {try {List<Category> list = cd.list(category, null);ResponseUtil.writeJson(resp, list);} catch (Exception e) {e.printStackTrace();}return null;}}

在點擊菜單欄需彈出一個增加的窗口

$(function(){$("#bookMenus").tree({url:$("#ctx").val()+"/permission.action?methodName=tree", // 給菜單欄一個點擊onClick: function(node){ // 判斷面板是否存在var exists=$("#bookTabs").tabs('exists',node.text);if(exists){$("#bookTabs").tabs('select',node.text);}else{$('#bookTabs').tabs('add',{ title:node.text, content:'<iframe width="100%" height="100%" src="'+$("#ctx").val()+node.attributes.self.url+'" />', closable:true}); }}}); })

通過數據庫內的類型傳到增加窗口的下拉框，使其靈活性

<input id="cid" name="cid" value="" label="類別" >

?二、書籍上架下架新增功能

新增頁面所需的屬性實體類

private long id;
? ? private String name;
? ? private String pinyin;
? ? private long cid;
? ? private String author;
? ? private float price;
? ? private String image;
? ? private String publishing;
? ? private String description;
? ? private int state;
// ? ?查詢時間的時候用這個格式
? ? @JsonFormat(pattern="yyyy-mm-dd HH:mm:ss",timezone="GMT+8")
? ? private Date deployTime;
? ? private int sales;

BookDao

public void add( Book t) throws Exception { // 轉化拼音t.setPinyin(PinYinUtil.getAllPingYin(t.getName()));t.setDeployTime(new Date());String sql="insert into t_easyui_book(name,pinyin,cid,author,price,image,publishing,description,state,deployTime,sales) values(?,?,?,?,?,?,?,?,?,?,?)";super.executeUpdate(sql, t, new String[] {"name","pinyin","cid","author","price","image","publishing","description","state","deployTime","sales"});}

?子控制器

public void add(HttpServletRequest req, HttpServletResponse resp) {try {bd.add(book);ResponseUtil.writeJson(resp, 1);} catch (Exception e) {e.printStackTrace();try {ResponseUtil.writeJson(resp, 0);} catch (Exception e1) {e1.printStackTrace();}}}

獲取數據，提交表單

/* 通過form控件提交 */function submitForm() {$('#ff').form('submit', { url:'${pageContext.request.contextPath}/book.action?methodName=add', success:function(data){ if(data==1){$('#ff').form('clear');}} }); }/* 刷新 */function clearForm() {$('#ff').form('clear');}

增加了之后就在未上架里?

?

?上架方法

// 查詢public List<Book> list(Book book, PageBean pageBean) throws Exception {String sql="select * from t_easyui_book where 1=1";String name=book.getName();int state = book.getState();if(StringUtils.isNotBlank(name)) {sql+=" and name like '%"+name+"%'";}if(state!=0) {sql+=" and state ="+state;}return super.executeQuery(sql, Book.class, pageBean);}// 上下架public void editStatus(Book book) throws Exception {super.executeUpdate("update t_easyui_book set state=? where id=?", book,new String[] {"state","id"});}

子控制器

如果上架，書籍的狀態改為2
如果下架，書籍的狀態改為3

public void list(HttpServletRequest req, HttpServletResponse resp) {PageBean pageBean=new PageBean();pageBean.setRequest(req);try {List<Book> list = bd.list(book, pageBean);ResponseUtil.writeJson(resp, new R().data("total", pageBean.getTotal()).data("rows", list));} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}public void editStatus(HttpServletRequest req, HttpServletResponse resp) {try {bd.editStatus(book);ResponseUtil.writeJson(resp, 1);} catch (Exception e) {e.printStackTrace();try {ResponseUtil.writeJson(resp, 0);} catch (Exception e1) {e1.printStackTrace();}}

js文件

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:'${pageContext.request.contextPath}/book.action?methodName=editStatus&state=2&id=' + row.id,success:function (data) {}})} }});}function xiajia() {$.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'); // 重新載入當前頁面數據 }})}}});}

?已上架展示效果
