layui table 跨页记忆选择

layui 表格功能目前默认不支持跨页记忆选择

下面来实现layui table跨页记忆选择实现

基于layui版本 1.4.5

表格跨页通用方法

//表格分页复选框
layui.define(['jquery', 'table'], function (exports) {
    var $ = layui.jquery
        , table = layui.table;

    //记录选中表格记录编号http://www.1994july.club/seo/?p=2797
    var checkedList = {};

    var tableCheckBoxUtil = {
        /*初始化分页设置*/
        init: function (settings) {
            var param = {
                //表格id
                gridId: ''
                //表格lay-filter值
                , filterId: ''
                //表格主键字段名
                , fieldName: ''
            };
            $.extend(param, settings);

            //设置当前保存数据参数http://www.1994july.club/seo/?p=2800
            if (checkedList[param.gridId] == null) {
                checkedList[param.gridId] = [];
            }

            //监听选中行
            table.on('checkbox(' + param.filterId + ')', function (obj) {
                var type = obj.type;
                var checked = obj.checked;
