<body>
<button>你好这里是我的第二个模块</button>
<h1>基本使用</h1>
<div>标题:{{article.title}}</div>
<div>阅读次数:{{article.count}}</div>
{% if article.count % 2 == 0 %}
<div>这是个偶数</div>
{% else %}
<div>这是个基数</div>
{% endif %}
{% set result1 = article.count / 100 %}
{% set result2 = result1 | int %}
<div>当前除以100的结果是: {{result2}}</div>
{% for i in range(result2) %}
<div>循环的每一项事: {{i+1}}</div>
{% endfor %}
<!--基本过滤器-->
<div>{{ article.content | safe }}</div>
<div>{{ 'hello word' | upper }}</div>
<div>{{ 'hello word' | title }}</div>
<div>{{ 'hello word' | lower }}</div>
<!-- 自定义过滤器 -->
<div>自定义过滤器{{ 1 | add }}</div>
<!-- 全局函数 -->
