easyui下拉框，增加以及商品的上架，下架

一、下拉框

1.将下拉框需要显示的值写入实体类

package com.mjx.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;
	}
 
	@Override
	public String toString() {
    
		return "Category [id=" + id + ", name=" + name + "]";
	}
 
}

2.dao方法进行查询

public List<Category> list(Category category, PageBean pageBean) throws Exception {
    
        String sql = "select * from t_easyui_category";
        long id = category.getId();
        if (id != 0) {
    
            sql += "and id=" + id;

        }
        return super.executeQuery(sql, Category.class, pageBean);
    }

3.action子控制器内调用

public String combobox(HttpServletRequest req, HttpServletResponse resp) {
    
        try {
    
            List<Category> list = categoryDao.list(category, null);
            ResponseUtil.writeJson(resp, list);
        } catch (Exception e) {
    
            e.printStackTrace();
        }
        return null;
    }

4.配置mvc文件

<action path="/category" type="com.mjx.web.CategoryAction">
    </action>

5.在表单中添加下拉框组件

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

 $(function () {
    
        $('#cid').combobox({
    
            url:'${pageContext.request.contextPath}/category.action?methodName=list',
            valueField:'id',
            textField:'name'
        });


    });

二、添加

1.添加表单

 <form id="ff" action="" method="post">
        <div style="margin-bottom:20px">
            <input class="easyui-textbox" name="name" style="width:100%" data-options="label:'书名:',required:true">
        </div>
        <div style="margin-bottom:20px">
            <input id="cid" name="cid" value="" label="类别" >
            <%--<select class="easyui-combobox" name="cid" label="类别" style="width:100%">--%>
                <%--<option value="1">文艺</option>--%>
                <%--<option value="2">小说</option>--%>
                <%--<option value="3">青春</option>--%>
            <%--</select>--%>
        </div>
        <div style="margin-bottom:20px">
            <input class="easyui-textbox" name="author" style="width:100%" data-options="label:'作者:',required:true">
        </div>
        <div style="margin-bottom:20px">
            <input class="easyui-textbox" name="price" style="width:100%"
                   data-options="label:'价格:',required:true">
        </div>
        <div style="margin-bottom:20px">
            <input class="easyui-textbox" name="publishing" style="width:100%"
                   data-options="label:'出版社:',required:true">
        </div>
        <div style="margin-bottom:20px">
            <input class="easyui-textbox" name="description" style="width:100%;height:60px"
                   data-options="label:'简介:',required:true">
        </div>
        <%--默认未上架--%>
        <input type="hidden" name="state" value="1">
        <%--默认起始销量为0--%>
        <input type="hidden" name="sales" value="0">
    </form>

2.给表单添加点击事件

<div style="text-align:center;padding:5px 0">
        <a href="javascript:void(0)" class="easyui-linkbutton" οnclick="submitForm()" style="width:80px">Submit</a>
        <a href="javascript:void(0)" class="easyui-linkbutton" οnclick="clearForm()" style="width:80px">Clear</a>
    </div>

3.提交表单和清空

//提交编辑信息的表单

function submitForm() {
    
	$('#ff').form('submit', {
    
		success : function(param) {
    
			$('#dd').dialog('close');
			$('#dg').datagrid('reload');
			$('#ff').form('clear');
		}
	});
}
 
function clearForm() {
    
	$('#ff').form('clear');
}

三、上架和下架

1.书籍实体类

package com.mjx.entity;
 
import java.util.Date;
 
import com.fasterxml.jackson.annotation.JsonFormat;
 
public class Book {
    
	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;
	@JsonFormat(pattern="yyyy-MM-dd HH-mm-ss",timezone="GMT+8")
	private Date deployTime;
	private int sales;
 
	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 String getPinyin() {
    
		return pinyin;
	}
 
	public void setPinyin(String pinyin) {
    
		this.pinyin = pinyin;
	}
 
	public long getCid() {
    
		return cid;
	}
 
	public void setCid(long cid) {
    
		this.cid = cid;
	}
 
	public String getAuthor() {
    
		return author;
	}
 
	public void setAuthor(String author) {
    
		this.author = author;
	}
 
	public float getPrice() {
    
		return price;
	}
 
	public void setPrice(float price) {
    
		this.price = price;
	}
 
	public String getImage() {
    
		return image;
	}
 
	public void setImage(String image) {
    
		this.image = image;
	}
 
	public String getPublishing() {
    
		return publishing;
	}
 
	public void setPublishing(String publishing) {
    
		this.publishing = publishing;
	}
 
	public String getDescription() {
    
		return description;
	}
 
	public void setDescription(String description) {
    
		this.description = description;
	}
 
	public int getState() {
    
		return state;
	}
 
	public void setState(int state) {
    
		this.state = state;
	}
 
	public Date getDeployTime() {
    
		return deployTime;
	}
 
	public void setDeployTime(Date deployTime) {
    
		this.deployTime = deployTime;
	}
 
	public int getSales() {
    
		return sales;
	}
 
	public void setSales(int sales) {
    
		this.sales = sales;
	}
 
	@Override
	public String toString() {
    
		return "Book [id=" + id + ", name=" + name + ", pinyin=" + pinyin + ", cid=" + cid + ", author=" + author
				+ ", price=" + price + ", image=" + image + ", publishing=" + publishing + ", description="
				+ description + ", state=" + state + ", deployTime=" + deployTime + ", sales=" + sales + "]";
	}
 
}

2.书籍的dao方法增改查

public List<Book> list(Book book, PageBean pageBean) throws Exception {
    
		String sql = "select * from t_eastui_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);
	}
 
	public void edit(Book t) throws Exception {
    
		// TODO Auto-generated method stub
		super.executeUpdate("update t_easyui_book set name=?,pinyin=?,cid=?,image=?,state=?,sales=? where id=?", t,
				new String[] {
     "name", "pinyin", "cid", "image", "state", "sales", "id" });
	}
 
	public void add(Book t) throws Exception {
    
		t.setPinyin(PinYinUtil.getAllPingYin(t.getName()));
		super.executeUpdate(
				"insert into t_easyui_book(name,pinyin,cid,author,price,image,publishing,description,state,deployTime,sales) values(?,?,?,?,?,?,?,?,?,?,?)",
				t, new String[] {
     "name", "pinyin", "cid", "author", "price", "image", "publishing", "description",
						"state", "deployTime", "sales" });
	}

3.书籍的action

package com.mjx.web;
 
import java.util.List;
 
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
import com.mjx.dao.BookDao;
import com.mjx.entity.Book;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.PageBean;
import com.zking.util.R;
import com.zking.util.ResponseUtil;
 
public class BookAction extends ActionSupport implements ModelDriver<Book> {
    
	private Book book = new Book();
	private BookDao bookDao = new BookDao();
 
	@Override
	public Book getModel() {
    
		// TODO Auto-generated method stub
		return book;
	}
 
	public void list(HttpServletRequest req, HttpServletResponse resp) {
    
		PageBean pageBean = new PageBean();
		pageBean.setRequest(req);
		try {
    
			List<Book> list = bookDao.list(book, pageBean);
			ResponseUtil.writeJson(resp, new R().data("total", pageBean.getTotal()).data("rows", list));
		} catch (Exception e) {
    
			e.printStackTrace();
		}
	}
 
	public void add(HttpServletRequest req, HttpServletResponse resp) {
    
		try {
    
			bookDao.add(book);
			ResponseUtil.writeJson(resp, 0);
		} catch (Exception e) {
    
			e.printStackTrace();
		}
	}
/** * 如果上架，书籍的状态改为2 * 如果下架，书籍的状态改为3 * @param req * @param resp */
	public void upDown(HttpServletRequest req, HttpServletResponse resp) {
    
		try {
    
			bookDao.edit(book);
			ResponseUtil.writeJson(resp, 1);
		} catch (Exception e) {
    
			e.printStackTrace();
			try {
    
				ResponseUtil.writeJson(resp, 1);
			} catch (Exception e1) {
    
				e.printStackTrace();
			}
		}
	}
 
	public void editStatus(HttpServletRequest req, HttpServletResponse resp) {
    
		try {
    
			bookDao.editStatus(book);
			ResponseUtil.writeJson(resp, 1);
		} catch (Exception e) {
    
			e.printStackTrace();
			try {
    
				ResponseUtil.writeJson(resp, 1);
			} catch (Exception e1) {
    
				e.printStackTrace();
			}
		}
	}
}

4.配置mvc文件

<action path="/book" type="com.mjx.web.BookAction">
    </action>

5.上架的js代码

function shangjia() {
    
		$.messager
				.confirm(
						'确认',
						'您确认想要上架此书籍吗？',
						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) {
    
 
												}
											})
								}
							}
						});
 
	}

6.下架的js代码

function xiajia() {
    
        $.messager.confirm('确认','您确认想要下架此书籍吗？',function(r){
    
            if (r){
    
                var row = $('#dg').datagrid('getSelected');
                if (row){
    
                    $.ajax({
    
                        url:'${pageContext.request.contextPath}/book.action?methodName=shangjia&state=3&id=' + row.id,
                        success:function (data) {
    
 
                        }
                    })
                }
            }
        });
 
    }

注意：书籍状态（1 未上架 2 已上架 3 已下架 默认值1）
效果：
新增了一本书

上架

下架
