篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了如何优雅的用js动态添加html代码相关的知识，希望对你有一定的参考价值。
一、使用javascript 模板引擎用javascript预编译模版，就是动态修改模板文件使之成为一个可用的静态html文件。 我平时会使用artTemplate，性能很好而且易上手。
编写模板
使用一个type="text/html"的script标签存放模板：
<script id="test" type="text/html">
<h1>title</h1>
<ul>
each list as value i
<li>索引 i + 1 ：value</li>
/each
</ul>
</script>
渲染模板
var data =
title: \'标签\',
list: [\'文艺\', \'博客\', \'摄影\', \'电影\', \'民谣\', \'旅行\', \'吉他\']
;
var html = template(\'test\', data);
document.getElementById(\'content\').innerHTML = html;
二、使用CoffeeScript
CoffeeScript支持类似于Python的跨行字符串，这样很轻易的就能保持HTML结构的可读性，而不需要使用“+”或者采用拼数组的形式。
str="""
<div class="dialog">
<div class="title">
<img src="close.gif" />关闭
</div>
<div class="content">
<img src="delete.jpg" />
</div>
<div class="bottom">
<input id="Button2" type="button" value="确定" class="btn"/>
<input id="Button3" type="button" value="取消" class="btn"/>
</div>
</div>
""" 参考技术A 动态添加html代码很容易，但是优雅……这就难了，以为每个人理解的“优雅”不一样
JS动态添加删除html
本功能要求是页面传一个List 集合给后台而且页面可以动态添加删除html代码需求如下：
下面是jsp页面代码
