layui 数据表格+分页+搜索+checkbox+缓存选中项数据
在做数据表格的时候遇到了很多坑, 今天整理一下方便以后使用.
主要功能是使用数据表格, 做分页,做搜索, 还有checkbox, 支持全选.
当选中一些数据的时候, 数据切换页面数据在切换回来后,选中状态就消失了, 我们希望切换回来的时候, 选中状态还能存在, 因此做了个缓存, 使checkbox 保持选中状态.代码如下:
1.HTML 搜索输入框
2.HTML 搜索按钮
3.HTML table表格
4.HTML 时间格式转换
5. js 功能设定
6. 请求数据格式
//请求的数据格式

BUG网友解决方案(未测):
//实例
layui.use(['table','form'], function(){
var form = layui.form;
//form监听checkbox事件
form.on('checkbox', function(obj){
//当前元素
var data = $(obj.elem);
//遍历父级tr，取第一个，然后查找第二个td，取值 转换为Number
var id = Number(data.parents('tr').first().find('td').eq(1).text());
//选中or未选中
var check = obj.elem.checked;
//复选框状态
// var checkStatus = table.checkStatus('users');
//如果选中
if(check==true){
//如果缓存数组存在值
if(ids.length>0){
//id==0便是全选按钮
if(id==0){
//循环当前页面所有数据
