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？
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/
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...
老兄也是用Bootstrap的么
