在不加载整个页面的情况下以块形式呈现模板 [英] Render a template in block without loading the whole page
问题描述
我有一个名为base.html的模板，它看起来像这样简化:
I have a template called base.html which looks simplified like this:
<html>
<head>
<title>{% block title %} Title {% endblock %}</title>
</head>
<body>
<div class="header">
{% block header %}My Header{% endblock %}
</div>
<div class="navigation">
{% block navigation %}My Navi{% endblock %}
</div>
<div class="content">
{% block content %}Content{% endblock %}
</div>
</body>
</html>
当我单击导航中的链接时，我想在内容块中呈现新内容，而无需再次加载标题和导航.
When i click on a link in the nav i want to render the new content in the content block without loading the header and navigation again.
推荐答案
您有两种选择:Ajax或iFrames
You have a couple of choices: Ajax or iFrames
如果您使用Ajax路由，则可以在服务器端呈现模板并在Ajax响应中返回HTML:
If you go the Ajax route, you can render a template server-side and return the HTML in the Ajax response:
import json
from django.http import HttpResponse
from django.template.loader import render_to_string
def render_template(request):
result = {'html': render_to_string('your-template.html', {})}
return HttpResponse(json.dumps(result, ensure_ascii=False),
content_type='application/json')
然后，您可以使用jQuery或任何需要更新主页中HTML的地方.
Then you can use jQuery or whatever you want to update the HTML in the main page wherever you need.
或者，您可以使用JavaScript设置单击时iFrame的src以呈现视图，而无需更新整个页面.就用户体验，维护等方面而言，这仅取决于最适合您的情况.
Alternatively, you can use JavaScript to set the src of an iFrame on click to render a view without updating the entire page. It just depends on what's best for you in terms of user experience, maintenance, etc.
