layui table动态表头 改变表格头部 重新加载表格

发布时间:2019-04-04 14:00:26发布者:Mr.Zhang阅读(473)

改变头部原理: 删除原来表格, 重新建立DOM元素, 重新加载table,实现表头改变

明白了原理, 我相信大家都能写出来了, table.reload(ID, options)目前好像还不支持cons的基础函数变动,只能使用其他方式了,简单暴力,哈哈哈哈哈哈哈哈嗝!!

下面是示例:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="static/layui/css/layui.css">
</head>
<body>
<div id="myTable">
    <table id="demo" lay-filter="test"></table>
</div>
<button id="buttonChangeTitle" class="layui-btn ">点击改变表头</button>

<script type="text/javascript" src="static/layui/layui.js" charset="utf-8"></script>
<script>
    layui.use(['element', 'jquery', 'table'], function () {
        var $ = layui.jquery
            , table = layui.table
            , element = layui.element; //Tab的切换功能,切换事件监听等,需要依赖element模块

        var data = [
            {
                "id": 10000,
