Question

我使用node.js，express和angular.js制作个人博客。索引页面上有一个链接：<a href="/">Home</a>。（它在layout.jade文件中如下所示）

当我使用地址http://localhost:8000/加载索引页面时，一切都很好，ng-view正确加载了我的内容。但是当我点击Home链接时，ng-view中的所有内容都消失了，我已经挖了很长时间，但仍然无法找出原因。

我的代码如下。

app.js

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var routes = require('./routes/index');
var api = require('./routes/api');
var fs = require('fs');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: false
}));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
app.use('/api', api);

app.get('/partials/:name', function (req, res) {
    var name = req.params.name;
    //res.render('partials/' + name);
    res.render('partials/' + name);
});

// catch 404 and forward to error handler
app.use(function(req, res, next) {
    var err = new Error('Not Found');
    err.status = 404;
    next(err);
});

// error handlers

// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
    app.use(function(err, req, res, next) {
        res.status(err.status || 500);
        res.render('error', {
            message: err.message,
            error: err
        });
    });
}


// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
        message: err.message,
        error: {}
    });
});
module.exports = app;

routes / index.js （这是快速路线，不是angular.js）

var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
    res.render('index', { title: 'My Blog' });
});

module.exports = router;

routes.js （angular.js）

angular.module('blogApp', ['ngRoute']).
  config(['$routeProvider', function($routeProvider) {
    $routeProvider.
      when('/', {
        templateUrl: 'partials/index',
        controller: IndexCtrl
      });
  }]);

index.jade

extends layout

block content
    #main
        #content
            .ng-view
        #side
            ...(omitted)

block scripts
        link(rel='stylesheet', type='text/css', href='/stylesheets/index.css')

layout.jade

doctype html
html(ng-app='blogApp')
    head
        title=title
        base(href='/')
        link(rel='stylesheet', type='text/css', href='/stylesheets/vendors/bootstrap.min.css')
        link(rel='stylesheet', type='text/css', href='/stylesheets/vendors/bootstrap-theme.css')
        link(rel='stylesheet', type='text/css', href='/stylesheets/layout.css') 
        script(src='/javascripts/vendors/jquery-1.11.3.min.js')
        script(src='/javascripts/vendors/jquery.form.js')
        script(src='/javascripts/vendors/angular.js')
        script(src='/javascripts/vendors/angular-route.js')
        script(src='/javascripts/vendors/bootstrap.js')
        script(src='/javascripts/vendors/satellizer.js')
        script(src='/javascripts/views/login.js')
        script(src='/javascripts/angular/controllers.js')
        script(src='/javascripts/angular/routes.js')
    body
        #container
            hgroup.header
                h1 My Blog
            #menu
                ul
                    li
                        a(href='/') Home  //Here is the link
                    li.nav-login
                        a(href='login') Login
            block content
        block scripts

Answer 1

您可以尝试使用ng-href替换元素中的href属性。

<a href = "http://localhost:8000/"> Home </a>

到

<a ng-href="#/"> Home </a>

我认为这会解决您的问题。

如果您仍然遇到同样的问题，可以通过更改 routes.js 来实现，如下所示，

angular.module('blogApp', ['ngRoute']).
  config(['$routeProvider', function($routeProvider) {
    $routeProvider.
      when('/', {
        templateUrl: 'partials/index',
        controller: IndexCtrl
      })
      .otherwise('/');
  }]);

然后尝试使用href中的任何链接;）

Answer 2

将您的主页链接的href与实际的本地主机网址相匹配。

`<a href = "http://localhost:8000/"> Home </a>

单击＆＃34; Home＆＃34;链接
