python - Flask 怎样获取当前页面的相对路径

Question

如题，当前页面为 "/about" 时，就 active

<a href="#"{% if 当前路径 == "/about" %} class="active"{% endif %}>About</a>

类似上面这种，当前路径如何获取？

Answer 1

可以使用request.path
官方文档如下：
http://flask.pocoo.org/docs/0.10/api/#incoming-request-data

In this case the values of the above mentioned attributes would be the following:

path         /page.html
script_root  /myapplication
base_url     http://www.example.com/myapplication/page.html
url          http://www.example.com/myapplication/page.html?x=y

url_root http://www.example.com/myapplication/

Answer 2

老兄也是用Bootstrap的么

Answer 3

javascruot $(function(){ var href = location.href; var x = href.match(/\/[\w\/]+$/); if(x && x[0]){ $(".side-nav >li").find('a[href="'+x[0]+'"]').parent().addClass("active-nav"); } });

简单又方便...
