标签:pre   content   load   更新表格   else   输出   null   cin   word   

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;
                console.log(table);
 
                //当前页数据
                var currentPageData = table.cache[param.gridId];
                //当前选中数据
                var checkRowData = [];
                //当前取消选中的数据
                var cacelCheckedRowData = [];
 
                //debugger;
                //选中
                if (checked) {
                    checkRowData = table.checkStatus(param.gridId).data;
                }
                //取消选中
                else {
                    if (type == ‘all‘) {
                        cacelCheckedRowData = currentPageData;
                    }
                    else {
                        cacelCheckedRowData.push(obj.data);
                    }
                    //console.log(cacelCheckedRowData);
                }
                //debugger;

                $.each(cacelCheckedRowData, function (index, item) {
