切换活动链接Bootstrap导航栏 [英] Toggle active link Bootstrap navbar

问题描述

我已经阅读了很多关于该主题的文章，发现几乎总是相同的解决方案，但是它对我不起作用...

I've read a lot of posts on the subject, found almost always the same solution but it does not work for me...

我的问题如下:我想使用Twitter Bootstrap 2.3.2及其导航栏，因此我包括css和js文件.在此之前，我还包括了jquery.然后，我以引导站点上显示的示例为例，该示例显示得很好.但是，我现在想将单击的菜单项设置为活动，并从所有其他菜单中删除活动的类.我在bootstrap.js文件中看到此函数是内置的，因此不再需要包含任何脚本代码.问题在于菜单项永远不会切换到活动状态.然后，我尝试添加一个jquery脚本以强制删除所有活动类，并将活动类添加到所单击的一项.什么都没发生.

My problem is as follows : I want to use Twitter Bootstrap 2.3.2 and its navbar, so I include the css and js files. Just before that, I also include jquery. I then take an example given on the bootstrap site which display very well. However, I now want to set the menu item clicked as active and remove the active class from all others. I saw in the bootstrap.js file that this function is built in, so no more script code to include. The problem is that the menu items do never toggle to active. I then tried to add a jquery script to force removing all active classes and add the active class to the one item that was clicked. Nothing happened.

所以请帮忙！我在jsfiddle中尝试了相同的代码，但效果很好，所以问题出自jade吗?从快递布局?如何解决?

So please, help !! I tried the same code in jsfiddle and it works fine, so does the problem comes from jade ? from express layout ? how to fix it ?

这是我使用的代码:

server.js

var express = require('express');
var app = express();
var port = 3000;

app.set('view engine', 'jade');
app.set('view options', {layout: true});
app.set('views', __dirname + '/views');

app.configure(function () {
    this.use(express.cookieParser());
    this.use(express.session({ secret: 'shhhhhhhhh' }));
    this.use(express.static(__dirname + '/public'));
    this.use(app.router);
});

app.get('/', function (req, res) {
    res.render('index')
    });
});

app.get('/about', function (req, res) {
    res.render('about')
    });
});

app.listen(port, function () {
  console.log('listening in http://localhost:' + port);
});

/views/layout.jade

            div.nav-collapse.collapse
              ul.nav
                li.active 
                  a(href='#') Home
                li 
                  a(href='#about') About
                li 
                  a(href='#Contact') Contact
     div.container             
        block content

/views/index.jade

extends layout

block content
   div.span6.offset3
      h1 Test Application
   div.span12
      h2 Test application!
      p This is a test application      
      button.btn.btn-success(type='button', onclick='')') Login

/views/about.jade

extends layout

block content
   div.span6.offset3
      h1 - About -

推荐答案

您可以在翡翠布局中尝试类似的方法:

You can try with something like that in you jade layout :

li(class=title=='Home'?'active':undefined)
  a(href="/") Home
li(class=title=='About'?'active':undefined)
  a(href="/about") About
li(class=title=='Contact'?'active':undefined)
  a(href="/contact") Contact

然后将其添加到您的server.js中:

Then just add this to your server.js :

app.get('/', function (req, res) {
  res.render('index', title: 'Home')
});

app.get('/about', function (req, res) {
  res.render('about', title: 'About')
});

这样，您还可以删除布局中的硬编码标题，并通过以下解决方案将其修改为:

This way, you can also remove the hard coded title in your layout and modify it through this solution as :

title #{title} | Test Application

它将作为您的房屋的标题呈现:

And it will render this as a title for your home :

Home | Test Application
