Layui 实现批量删除

function bathchDeleteUser() {
    //获取选中状态,为table的id
    var checkStatus = table.checkStatus('testReload');
    //获取选中数量
    var selectCount = checkStatus.data.length;
    console.log(checkStatus.data);
    if (selectCount == 0) {
        layer.msg('批量删除至少选中一项数据', function () {
        });
        return false;
    }
    layer.confirm('真的要删除选中的项吗？', function (index) {
        layer.close(index);
        index = layer.load(1, {shade: [0.1, '#fff']});

        let isStr = "";
        for (let i = 0; i < selectCount; i++) {
            isStr = isStr + "," + checkStatus.data[i].uid;
        }
        $.ajax({
            type: 'post',
            data: {"idsStr": isStr},
            url: 'http://localhost:8080/user_info/batch_delete',
            success: function (data) {
                if (data.code === 20000) {
                    layer.close(index);
                    layer.msg(data.msg);
                    //表格重载
                    table.reload('testReload', {
                        page: {
                            curr: 1 //重新从第 1 页开始
                        }
                    }, 'data');
                } else {
                    layer.msg(data.msg);
                }
            }
        });
    })
