<script>
和<template>
(推荐) 标签内的内容页面不会渲染,浏览器会默认添加display: none;
,也不能使用选择器定位子元素<script type=text/html >
或<script type="text/template" >
定义一个被JS调用的代码,内容不会被执行<div style="display: none">
与复用DOM结构后的id等重复:可以把DOM结构缓存到JS变量或标签属性内容,然后移除这个标签
select框默认选项为空白
<option selected="selected" disabled="disabled" style='display: none' value=''></option>
