ASP PHP JSP JavaScript 网页设计 DIVCSS Ajax技术 HTML5

{% use "blocks.html" with sidebar as parent_sidebar %}

{% block sidebar %}
{{ block('parent_sidebar') }}
{% endblock %}
{% extends "base.html" %}

{% use "blocks.html" with sidebar as parent_sidebar %}

{% block sidebar %}
    {{ block('parent_sidebar') }}
{% endblock %}
你可以使用任意数量的use标签，如果多个use标签里的block名字存在重复，那么最后use的那个有效。
spacelsee标签
会删除html标签之间的空白
{% spaceless %}
    <div>
        <strong>foo</strong>
    </div>
{% endspaceless %}

{# output will be <div><strong>foo</strong></div> #}
{% spaceless %}
    <div>
        <strong>foo</strong>
    </div>
{% endspaceless %}

{# output will be <div><strong>foo</strong></div> #}
autoescape标签
这个十分汗颜，我居然没看懂。我只知道字面上的意思是自动转义。。但是。。我做实验的时候还是不知道应怎么使用
他官方给的例子是
{% autoescape true %}
    Everything will be automatically escaped in this block
{% endautoescape %}

{% autoescape false %}
    Everything will be outputed as is in this block
{% endautoescape %}

{% autoescape true js %}
    Everything will be automatically escaped in this block
    using the js escaping strategy
{% endautoescape %}
{% autoescape true %}
    Everything will be automatically escaped in this block
{% endautoescape %}

{% autoescape false %}
Everything will be outputed as is in this block
{% endautoescape %}

{% autoescape true js %}
    Everything will be automatically escaped in this block
    using the js escaping strategy
{% endautoescape %}
而我这么测试。输出的还是原本的内容。
{% autoescape true %}
    <body><b>aaaa</b></body>
{% endautoescape %}

{% autoescape false %}
    <b>aaaa</b>
{% endautoescape %}

{% autoescape true js %}
    <script>
    function aaa(){alert('x');}
    </script>
{% endautoescape %}
{% autoescape true %}
    <body><b>aaaa</b></body>
{% endautoescape %}
