一、layui下拉表格多选

1、引入js

2、html

<div class="layui-input-inline">
	<input type="text" name="" id="bps_ex3" placeholder="已安放数多选查询" autocomplete="off" class="layui-input" readonly>
</div>

<div style="display:none">
	<input type="hidden" id="yafs" name="yafs" value=""/>
</div>

3、js代码

①非动态数据

tableSelect.render({
			elem: '#bps_ex3',
			searchKey: 'nodenameSearch',
			checkedKey: 'name',
			searchPlaceholder: '数量',
			table: {
				limit: 300,
				//url: './CemeterybasicAction.jsp?act=getSelectAf',
				data: [
					//默认选中使用selected: true   
		　　　　　　{ name: '1', value: '1' },
					{ name: '2', value: '2' },
					{ name: '3', value: '3' },
					{ name: '4', value: '4' },
					{ name: '5', value: '5' },
					{ name: '6', value: '6' },
					{ name: '7', value: '7' },
				],
				cols: [[
					{ type: 'checkbox' },
					{ field: 'name', title: '数量', width: 200 }
				]],
				page: false,
			},
			done: function (elem, data) {
				var NEWJSON = []
				layui.each(data.data, function (index, item) {
					NEWJSON.push(item.name);
				})
				$("#yafs").val(NEWJSON.join(","));
				$('#btnsearch').click();
				elem.val(NEWJSON.join(","))
			}
		})

②动态数据

后端接口就不放出来了，大家按照自己需要的数据进行一个查询就行，记得修改url地址

tableSelect.render({
			elem: '#bps_ex3',
			searchKey: 'nodenameSearch',
			checkedKey: 'name',
			searchPlaceholder: '数量',
			table: {
				limit: 300,
				url: './CemeterybasicAction.jsp?act=getSelectAf',
				cols: [[
					{ type: 'checkbox' },
					{ field: 'name', title: '数量', width: 200 }
				]],
				page: false,
			},
			done: function (elem, data) {
				var NEWJSON = []
				layui.each(data.data, function (index, item) {
					NEWJSON.push(item.name);//与列名一致
				})
				$("#yafs").val(NEWJSON.join(","));
				$('#btnsearch').click();
				elem.val(NEWJSON.join(","))
			}
		})

4、运行效果

总结：1、若不是动态数据可如上图所示
2、若表格绑定动态数据，即调用后端的接口，接口内写查询所需要的数据，url处填写自己的接口地址

二、sql server批量插入

insert into t_fs (ccid,sxk)

SELECT  t1.sid,'数学' as sxk
FROM  t_student t1 left outer join 
t_coure t2 on t1.sid=t2.c_id
where t2.cid is null

---------------------------------------------------------------
insert into t_fs (需要插入的列名)

SELECT  对应需要插入的列名
FROM  t_student(表名) t1 left outer join 
t_coure t2 on t1.sid=t2.c_id
where t2.cid is null

三、根据身份证号动态填写出生日期年龄性别

初代身份证为15位数，所以以下分为两种情况

var sfz=data.sfz;//根据自身情况拿到输入的身份证号
let _IDRe18 = /^([1-6][1-9]|50)\d{4}(18|19|20)\d{2}((0[1-9])|10|11|12)(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$/
let _IDre15 =  /^([1-6][1-9]|50)\d{4}\d{2}((0[1-9])|10|11|12)(([0-2][1-9])|10|20|30|31)\d{3}$/

if( _IDRe18.test(sfz) || _IDre15.test(sfz)) {
	if(sfz.length==18 || sfz.length==15){
		//获取出生日期
					var birthday = sfz.substring(6, 10) + "-" + sfz.substring(10, 12) + "-" + sfz.substring(12, 14);
					//获取年龄
					var ageDate = new Date();
					var month = ageDate.getMonth() + 1;
					var day = ageDate.getDate();
					var age = ageDate.getFullYear() - sfz.substring(6, 10) - 1;
					if (sfz.substring(10, 12) < month || sfz.substring(10, 12) === month && sfz.substring(12, 14) <= day) {
						age++;
					}
					if (age <= 0) {
						age = 1;
					}
					var sex="";
					//获取性别
					if (parseInt(sfz.substr(16, 1)) % 2 === 1) {
						sex = "男";
					} else {
						sex = "女";
					}
					obj.update({
						b_birth:birthday
						,c_ex15:age
						,b_sex:sex
					});
				}else if(sfz.length==15){
					//获取出生日期
					var birthday = "19"+sfz.substring(6, 8) + "-" + sfz.substring(8, 10) + "-" + sfz.substring(10, 12);
					//获取性别
					var usex = sfz.substring(14, 15);// 用户的性别
					var sex="";
					if (parseInt(usex) % 2 == 0) {
						sex = "女";
						//sex = 2; // 女
					} else {
						sex = "男";
						//sex = 1; // 男
					}
					//获取年龄
					var ageDate = new Date();
					var month = ageDate.getMonth() + 1;
					var day = ageDate.getDate();
					var nian = "19"+sfz.substring(6, 8);
					var age = ageDate.getFullYear() - nian - 1;
					if (sfz.substring(8, 10) < month || sfz.substring(10, 12) === month && sfz.substring(10, 12) <= day) {
						age++;
					}
					if (age <= 0) {
						age = 1;
					}
					//以下是对表格的修改，大家根据自己html代码种的输入框进行修改即可
					obj.update({
						birthday:birthday
						,age:age
						,sex:sex
					});
				}
				//重载表格数据
				layui.table.reload('demo');
	}
}else {
	alert("身份证格式有误");
}
