使用AngularJS的Twitter Bootstrap Navbar - 折叠不起作用

Question

我正在使用Angular和Twitter Bootstrap导航栏并尝试使折叠功能正常工作.

部分:program.html

<div class="navbar navbar-inverse navbar-static-top" ng-include="'partials/navbar.html'" ng-controller="NavbarCtrl"></div>

部分:navbar.html

<div class="navbar-inner">
    <div class="container">
        <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </a>
        <a class="brand" href="#">Short Course</a>
        <div class="nav-collapse collapse">
            <ul class="nav">
                <li><a href="#"><i class="icon-home icon-white"></i> Home</a></li>
                <li class="dropdown ng-class: settingsActive;">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Intro <b class="caret"></b></a>
                    <ul class="dropdown-menu">
                        <li><a onclick='$("#myModal").modal("show");'>User Info</a></li>
                        <li><a href="#/setup">Settings</a></li>
                        <li><a href="#/get-started">Getting started</a></li>
                    </ul>
                </li>
                <li class="dropdown ng-class: programActive;" ng-controller="ProgramCtrl">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Lessons <b class="caret"></b></a>
                    <ul class="dropdown-menu">
                        <li ng-repeat='o in lessonTypes'>
                            <a href="#/program/{{o.value}}">{{o.title}}</a>
                        </li>
                        <li class="divider"></li>
                        <li><a href="#/freeform">Free Form</a></li>
                    </ul>
                </li>
                <li class="dropdown ng-class: reportsActive;">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Grades <b class="caret"></b></a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Simple Report</a></li>
                        <li><a href="#">Comprehensive Report</a></li>
                        <li class="divider"></li>
                        <li><a href="#">Current Grade Report</a></li>
                        <li><a href="#">Final Grade Report</a></li>
                    </ul>
                </li>
            </ul>
            <ul class="nav pull-right">
                <li><a href="#/class"><i class="icon-upload icon-white"></i> Upload/Save</a></li>
                <li><a href="#/class"><i class="icon-off icon-white"></i> Save/Logout</a></li>
            </ul>
        </div><!-- /.nav-collapse -->
    </div>
</div><!-- /navbar-inner -->

导航栏显示完美.下拉菜单效果很好.Angular函数加载数据并将特定项标记为活动,并完美填充模型.唯一不起作用的是响应式折叠功能.当我调整屏幕大小时,菜单项会消失并显示菜单图标,但单击它不起作用.我坚持这个,我知道它必须是一个简单的解决方案,但我无法弄明白.任何帮助,将不胜感激!

对于那些感兴趣的人 - 这是在没有Bootstrap的javascript的情况下实现这一点的另一种方式.

导入Angular的UI-Bootstrap.

HTML:

<div class="navbar navbar-inverse" ng-controller="NavBarCtrl">
<div class="navbar-inner">
    <div class="container">
        <button class="btn btn-navbar" ng-click="isCollapsed = !isCollapsed"> 
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
        </button> <a class="brand" href="#">Short Course</a>
        <div class="nav-collapse" uib-collapse="isCollapsed">
            <ul class="nav">
                <li><a href="#"><i class="icon-home icon-white"></i> Home</a>
                </li>
                <li><a href="#">Lessons</a>
                </li>
                <li><a href="#">Grades</a>
                </li>
            </ul>
            <ul class="nav pull-right">
                <li><a href="#/class"><i class="icon-upload icon-white"></i> Upload/Save</a>
                </li>
                <li><a href="#/class"><i class="icon-off icon-white"></i> Save/Logout</a>
                </li>
            </ul>
        </div>
        <!-- /.nav-collapse -->
    </div>
</div>
<!-- /navbar-inner -->
</div>

JS:

var myApp = angular.module('myApp', ['ui.bootstrap']);

function NavBarCtrl($scope) {
    $scope.isCollapsed = true;
}

我想让它与纯AngularJS一起工作,没有更多的JavaScript库,结果很简单.从这里的示例开始只需要进行两处更改(bootstrap v3):

代替

<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">

我用了:

<button type="button" class="navbar-toggle" ng-init="isCollapsed = true" ng-click="isCollapsed = !isCollapsed">

而不是

<div class="collapse navbar-collapse">

我用了:

<div class="navbar-collapse" ng-class="{collapse: isCollapsed}">

下拉菜单

此外,如果您的导航栏中有任何下拉菜单,则同样适用于它们,除了css类不是"崩溃",而是"打开":

<li class="dropdown" ng-class="{ open : dd1 }" ng-init="dd1 = false" ng-click="dd1 = !dd1">

请注意,多个下拉列表都需要在角度根范围内拥有自己的状态变量(如果您没有使用控制器).因此我在这里命名了第一个下拉列表'dd1',它们需要是唯一的,否则多个下拉列表将同时打开/关闭.(这很有趣,但很少使用).

Answer 3

这是一个棘手的问题.文档显示了一种方式,它的功能很好.我复制了文档示例(http://twitter.github.com/bootstrap/components.html#navbar)并尝试使用它.然后我转到示例页面并尝试了此处列出的布局:http://twitter.github.com/bootstrap/examples/fluid.html

唯一的区别是a <button>而不是<a>

<button type="button" class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">

代替

<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">

我不知道为什么,但改变它使它功能很好.

编辑

Arbiter指出,它<a />缺少href='#'属性.添加该属性也可以解决问题.

Answer 4

无需使用控制器.只需在初始编译模板时使用ng-init初始化isCollapsed标志.

<div class="navbar navbar-inverse" ng-controller="NavBarCtrl">
<div class="navbar-inner">
    <div class="container">
        <button class="btn btn-navbar" ng-init="isCollapsed = true" ng-click="isCollapsed = !isCollapsed"> 
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
        </button> <a class="brand" href="#">Short Course</a>
        <div class="nav-collapse" collapse="isCollapsed">
            <ul class="nav">
                <li><a href="#"><i class="icon-home icon-white"></i> Home</a>
                </li>
                <li><a href="#">Lessons</a>
                </li>
                <li><a href="#">Grades</a>
                </li>
            </ul>
            <ul class="nav pull-right">
                <li><a href="#/class"><i class="icon-upload icon-white"></i> Upload/Save</a>
                </li>
                <li><a href="#/class"><i class="icon-off icon-white"></i> Save/Logout</a>
                </li>
            </ul>
        </div>
        <!-- /.nav-collapse -->
    </div>
</div>
<!-- /navbar-inner -->
</div>

Answer 5

如果您正在寻找Angular2.然后打击是所需的更改.

<button type="button" class="navbar-toggle collapsed" (click)="toggleCollapse()"
        aria-expanded="false">

和菜单应该是这样的.

<div class="navbar-collapse" id="bs-navbar-collapse" [class.collapse]="isCollapsed">
      <ul class="nav navbar-nav">
        <li>
          <a href="">
            Dashboard

你的控制器应该是这样的.

import { Component} from '@angular/core';

@Component({
  selector: 'app-navbar',
  templateUrl: './navbar.component.html',
  styleUrls: ['./navbar.component.css']
})
export class NavbarComponent {
  isCollapsed: boolean = true;

  toggleCollapse(): void {
    this.isCollapsed = !this.isCollapsed;
  }

}

看,这相对容易了angular2.感谢@yankee的回答.
