layui 的表格table里设置多个复选框，如何实现全选等功能，如下图：

 实现代码如下：
 

<!--数据表格-->
	<table class="layui-hide" id="tableId" lay-filter="tableFilter"></table>    
<div class="layui-row">
<div class="layui-inline">
<button class="layui-btn" id="checkall">全选</button>
</div>
<div class="layui-inline">
<button class="layui-btn" id="checkoff">全不选</button>
</div>
<div class="layui-inline">
<button class="layui-btn" id="okrecom">确认推荐</button>
</div>
</div>
<script src="/skins/lib/layui/layui.js"></script>
<script>
	layui.use(["element", "jquery", "table", "form", "okLayer", "okUtils"], function () {
		let table = layui.table;
		let form = layui.form;
		let $ = layui.jquery;
		okLoading.close($);
		let userTable = table.render({
			elem: '#tableId',
			url: '/api',
			limit: 15,
			page: false,
			toolbar: true,
			toolbar: "#toolbarTpl",
			size: "sm",
			cols: [[
				{field: "ids", title: '<input type="checkbox" id="idsall" lay-skin="primary">医院详情推荐', width: 150,templet:function(d){ 
				var chk=d.yytj>0 ?' checked':'';
				return '<input type="checkbox" name="ids" value="'+d.docid+'" lay-skin="primary"'+chk+'>';
				}},
				{field: "is_tj", title: '<input type="checkbox" id="tjall" lay-skin="primary">医院站首页推荐', width: 150,templet:function(d){ 
				var chk=d.yysite_index>0 ?' checked':'';
				return '<input type="checkbox" name="is_tj" value="'+d.docid+'" lay-skin="primary"'+chk+'>';
				}},
				{field: 'docid', hide: true},
				{field: "name", title: "医生姓名", width: 100},
				{field: "jobtxt", title: "医生职称", width: 100},
				{field: "yytj", title: "医院详情状态", width: 150, templet: "#RezTpl"},
				{field: "yysite_index", title: "医院站首页状态", width: 150, templet: "#StatesTpl"},
			]],
			done: function (res, curr, count) {
				console.info(res, curr, count);
			}
		});
		$('.laytable-cell-1-0-0').on('click',".layui-form-checkbox",function(){
			var classname=$(this).attr('class');
			$("input[name=ids]").each(function() {
				(classname.indexOf("layui-form-checked") != -1)?$(this).attr('checked',''):$(this).removeAttr('checked');
				(classname.indexOf("layui-form-checked") != -1)?$(this).next().addClass('layui-form-checked'):$(this).next().removeClass('layui-form-checked');
			});
		});
		$('.laytable-cell-1-0-1').on('click',".layui-form-checkbox",function(){
			var classname=$(this).attr('class');
			$("input[name=is_tj]").each(function() {
				(classname.indexOf("layui-form-checked") != -1)?$(this).attr('checked',''):$(this).removeAttr('checked');
				(classname.indexOf("layui-form-checked") != -1)?$(this).next().addClass('layui-form-checked'):$(this).next().removeClass('layui-form-checked');
			});
		});
		$("#checkall").click(function() {
			$("input:checkbox").each(function() {
				$(this).attr('checked','')
			});
			$(".layui-form-checkbox").each(function() {
				$(this).addClass('layui-form-checked');

		$('.layui-table').on('click',".layui-form-checkbox",function(){
			($(this).attr('class').indexOf("layui-form-checked") != -1)?$(this).prev().attr('checked',''):$(this).prev().removeAttr('checked');
		})
		$("#okrecom").click(function() {
			var ids_value =[];//定义一个数组
			var is_tj_value =[];//定义一个数组
			$('input[name="ids"]').each(function(){//遍历每一个名字为nodes的复选框，其中选中的执行函数
				(typeof($(this).attr('checked'))!="undefined")?ids_value.push($(this).val()):'';//将选中的值添加到数组chk_value中
			});
			$('input[name="is_tj"]').each(function(){//遍历每一个名字为nodes的复选框，其中选中的执行函数
				(typeof($(this).attr('checked'))!="undefined")?is_tj_value.push($(this).val()):'';//将选中的值添加到数组chk_value中
			});
			okLayer.confirm("确认要推荐这些医生吗？", function () {
				$.ajax("hospital.php", "post", {'hospid': '{$hospid}','tjsubmit':true,'ids':ids_value,'is_tj':is_tj_value,'action':'czys','ajaxform':2}, true).done(function (response) {
					var icond=7;
					if(response.code==0){
						icond=1;
					}
					layer.msg(response.msg, {
						icon:icond,
						skin: 'layui-layer-molv' //样式类名
						,closeBtn: 0
						,time: 1000
					},
					function(index, item) {
						userTable.reload();
						$('.layui-table').on('click',".layui-form-checkbox",function(){
							($(this).attr('class').indexOf("layui-form-checked") != -1)?$(this).prev().attr('checked',''):$(this).prev().removeAttr('checked');
						})
					});
				}).fail(function (error) {
					console.log(error)
				});
			})
		});
		
	})
</script>
<script type="text/html" id="RezTpl">
   {{#  if(d.yytj>0){ }}
	<span style="color:#009688">医院详情页显示</span>
	{{#  }else{ }}
	医院详情页不显示
	{{#  } }}
</script>
<script type="text/html" id="StatesTpl">
   {{#  if(d.yysite_index>0){ }}
	<span style="color:#009688">医院站首页显示</span>
	{{#  }else{ }}
	医院站首页不显示
	{{#  } }}
</script>

实现效果如下：
