删除封装函数

    function delAll(school_id, school_name) {
        var lock = false;
        layer.confirm('确认要删除吗？', function (index) {
            if (!lock) {

                $.ajax({
                    type: "post",
                    url: "?m=School&a=schoolDeal&act=del",
                    async: true,
                    data: {

                    success: function (data) {
                        layer.msg(data + '删除成功', {icon: 1, time: 1000}, function () {
                            location.replace(location.href);
                        });

二次验证

 //二次验证

                return false;
            }
            //验证逻辑
            var num1 = Math.floor(Math.random() * 10) + 1;
            var num2 = Math.floor(Math.random() * 10) + 1;
            var correctAnswer = num1 + num2;
            layer.open({
                type: 1,
                area: '350px',
                resize: false,
                //shadeClose: true,

                <div class="layui-input-inline" style="width: 40%;">
                  <input type="number" name="userAnswer" lay-verify="required" autocomplete="off" class="layui-input" lay-affix="clear">

          </div> `,
                success: function () {
                    form.render();// 对弹层中的表单进行初始化渲染

                    // 表单提交事件
                    form.on('submit(demo-login)', function (data) {
                        var field = data.field;
                        //console.log(field.userAnswer);
                        if (field.userAnswer == correctAnswer) {
                            delAll(school_id, school_name);//执行删除操作
                        } else {
                            layer.alert('结果不正确，请重新验证！', {icon: 2, time: 1000});
                        }
                        return false;
                    });
                }
            });
        }

触发事件

        //触发事件
        table.on('toolbar(lockTable)', function (obj) {
            var checkStatus = table.checkStatus(obj.config.id);
            switch (obj.event) {
                case 'delete':
                    var data = checkStatus.data;
                    var school_id = [], school_name = [];
                    for (var i = 0; i < data.length; i++) {
                        school_id.push(data[i].school_id)
                        school_name.push(data[i].school_name)
                    }
                    //二次验证
                    Validation (school_id, school_name);
                    //delAll(school_id, school_name);
                    break;
                case 'add':
                    getPopUrl('添加数据', '?m=School&a=schoolAdd', '', '','');
