ssm批量刪除

1.DAO層usermapper:

<delete id="deleteMany" parameterType="String">
		delete from user where id in
		<foreach item="ids" collection="array" index="no" open="(" separator="," close=")">
			#{ids}
		</foreach>
</delete>

2.DAO層UserDao:

//批量刪除
public int deleteMany(String[] ids);

3.Service層UserService同上

4.Service層UserServiceImpl:

public int deleteMany(String[] ids) {
		// TODO Auto-generated method stub
		return userDao.deleteMany(ids);
	}

5.Controller層：

Map<String, String> ret = new HashMap<String, String>();
		 if(ids != null){
			 String[] d=ids.split(",");//把數組裏的值逗號隔開
			 if(userService.deleteMany(d) <=0){
				 ret.put("type", "error");
				 ret.put("msg", "刪除失敗！");
				 return ret;
			 }else{
				 ret.put("type", "success");
				 ret.put("msg", "刪除成功！");
				 return ret;
			 }
		 }

6.View層：

js:

//頂部批量刪除
	$('.delBtn').click(function() {
		var url=$(this).attr('data-url');
		dialog.confirm({
			message:'您確定要刪除選中項',
			success:function(){
				var Checkbox=false;//默認複選框爲空
				     $("input[name='id']").each(function(){//獲取複選框節點id
				      if (this.checked==true) {        
				        Checkbox=true;    //已勾選
				      }
				    });
				if (Checkbox){//boolean值爲true
				 obj = document.getElementsByName("id");//將複選框定義成一個jquery對象
				 check_val = [];//定義一個數組
			     for(k in obj){//k相當於i,往這個jquery對象添加勾選的id;
		         	if(obj[k].checked)//選中的都放進 數組裏
				    	check_val.push(obj[k].value);
				        }
				}
				$.ajax({//利用ajax發出請求
				    type:"POST",//post類型
					url:url+"?ids="+check_val, //向Controller裏的deleteSelect傳輸ids
					dataType : "json",//返回數據類型
					success : function(data) {
						if ("success" == data.type) {
							layer.msg(data.msg, {
								icon : 1,
								title : "提示",
								time : 1000
							});
						} else {
							layer.msg(data.msg, {
								icon : 2,
								title : "提示",
								time : 1000
							});
						}
						refresh();
					}
				}); 
			},
			cancel:function(){
				layer.msg('取消成功')
			}
		})
		return false;

	}).mouseenter(function() {

		dialog.tips('批量刪除', '.delBtn');

	})	

有table的jsp:

<table class="layui-table" lay-even lay-skin="nob">
							<colgroup>
								<col width="50">
								<col class="hidden-xs" width="50">
								<col class="hidden-xs" width="100">
								<col>
								<col class="hidden-xs" width="150">
								<col class="hidden-xs" width="150">
								<col width="80">
								<col width="150">
							</colgroup>
							<thead>
								<tr>
									<th><input type="checkbox" name="" lay-skin="primary" lay-filter="allChoose"></th>
									<th class="hidden-xs">ID</th>
									<th>姓名</th>
									<th class="hidden-xs">密碼</th>
									<th class="hidden-xs">類型</th>
									<th>操作</th>
								</tr>
							</thead>
							<tbody>
								<c:forEach items="${userList}" var="user">
									<tr>
										<td><input type="checkbox" value="${user.id}" name="id" lay-skin="primary" data-id="1"></td>
										<td class="hidden-xs">${user.id}</td>
										<td>${user.username}</td>
										<td>${user.password}</td>
										<td class="hidden-xs">${user.type}</td>

											<div class="layui-inline">
