本文介绍了一种利用Django框架实现网页模板继承的方法，并通过具体示例详细展示了如何在子模板中覆盖和扩展基模板的内容。同时，文章还介绍了如何在子模板中加载静态资源以及如何传递参数。

网站的继承

base.html 为继承的页面

<!DOCTYPE html>
<html>
{% load staticfiles %}
<head>
    <meta charset="UTF-8">
    <meta name="renderer" content="webkit">
    <meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1" >
	<title>{% block title %}慕学在线首页{% endblock %}</title>
	<link rel="stylesheet" type="text/css" href="{% static 'css/reset.css' %}">
	<link rel="stylesheet" type="text/css" href="{% static 'css/animate.css' %}">
	<link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}">
    {% block custom_css %}{% endblock %}
    <script src="{% static 'js/jquery.min.js' %}" type="text/javascript"></script>
    <script src="{% static 'js/jquery-migrate-1.2.1.min.js' %}" type="text/javascript"></script>

</head>

子页面想要改动继承页面的内容使用 {% block title %}{%endblock%} 方式

在子模版中：org-list.html

{% extends 'base.html'%}   继承base.html
{% block title %} 课程机构列表 - 慕学在线网 {%endblock%}    只替换base.html中的title

虽然在母模板中，有{% load staticfiles %}，但在子模版中如果要用到静态文件，仍要写入{% load staticfiles %}

参数的向上传递：

比如在view中return render（request,'register.html',{'form':form})

如果register.html继承的base.html文件，在base.html页面中也是可以用form变量

最终 org-list.html 为

{% extends 'base.html' %}
{% block title %}课程机构列表 - 慕学在线网{% endblock %}
{% load staticfiles %}
{% block custom_bread %}
