layui table動態(tài)表頭改變表格頭部重新加載表格的方法

更新時間：2019年09月21日 09:58:01 作者：```...簡單點

今天小編就為大家分享一篇layui table動態(tài)表頭改變表格頭部重新加載表格的方法，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

改變頭部原理：刪除原來表格, 重新建立DOM元素, 重新加載table,實現(xiàn)表頭改變

明白了原理, 我相信大家都能寫出來了, table.reload(ID, options)目前好像還不支持cons的基礎函數(shù)變動,只能使用其他方式了,簡單暴力,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" rel="external nofollow" >
</head>
<body>
<div id="myTable">
  <table id="demo" lay-filter="test"></table>
</div>
<button id="buttonChangeTitle" class="layui-btn ">點擊改變表頭</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的切換功能，切換事件監(jiān)聽等，需要依賴element模塊
