// 删除全选的数据 function delAll() {     chooseAllstr = '';     $(".layui-form-checked").each(function() {         if ($(this).parent().find('input').data("id") && $(this).parent().find('input').data("id") != undefined) {             chooseAllstr += $(this).parent().find('input').data("id") + ','         }     })     if (chooseAllstr != '') {         //询问框         layer.confirm('确认删除全部记录吗？', {             btn: ['删除', '取消'] //按钮         }, function() {             ajax('/pu/ScancodeBehavior/Delete', { idList: chooseAllstr }, function(data) {                 if (data.success) {                     layer.closeAll();                     popupSuccess(data.msg);                     getList(param, function(data) {                         if (Number(data.count) != 0) {                             var getTpl = tabletpl.innerHTML,                                 view = document.getElementById('table-adm');                             laytpl(getTpl).render(data.list, function(html) {                                 view.innerHTML = html;                             });

-------------------------------------------------------------------　　

如果想用layui的name属性获取选中的数据：

?

1	<span lay-submit lay-filter="deteleSubmit">删除记录</span>

　　拼接为逗号分割的字符串，供接口传参，进行删除

?

1 2 3 4 5 6 7 8

form.on('submit(deteleSubmit)', function(data) {              var shuzu = [];     var arr = '';     Object.keys(data.field).forEach(function(key) {         shuzu.push(data.field[key]);     });     arr = shuzu.join(","); })
