You're actually supposed to implement such a thing using a router, ui-bootstrap is just a UI library. The ui-router wiki explains how to accomplish this using multiple views per state.
Let's say we have two states in which we want to have a shared navbar, than define 2 states and provide each with 2 views, one navbar and another for the body
Provide each navbar view the same controller and template
$stateProvider
.state('stateA',{
views: {
'navbar#stateA': {
templateUrl: 'navbar.html', // <-- navbar html goes here
controller: 'navbarCtrl'
},
'body#stateA': {
templateUrl: 'report-table.html',
controller: 'StateACtrl'
}
}
})
.state('stateB',{
views: {
'navbar#stateB': {
templateUrl: 'navbar.html',
controller: 'navbarCtrl'
},
'body#stateB': {
templateUrl: 'report-table.html',
controller: 'StateBCtrl'
}
}
})
Inside your markup, you should maintain
<body>
<!-- the router will replace this with your html files -->
<div ui-view="navbar"></div>
<div ui-view="body"></div>
</body>

On the open body tag, make a javascript function named start onLoad="start()" Then within the function set the innerhtml the navbar code.
HTML:
<body onLoad="start()">
<div id="navbar"></div>
</body>
JS:
function start() {
document.getElementById("navbar").innerHTML = "<nav class="navbar navbar-inverse" ng-controller="HeaderController">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Logo</a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav">
<li class="active">Home</li>
<li>About</li>
<li>Contact</li>
</ul>
</div>
</div>
</nav>";
}

There are a couple ways to do this without copying the whole navigation bar into every HTML file.
You can put all of the content in the same page and use JavaScript to hide/show specific sections when you click on the menu link
You can use JavaScript to retrieve the new content via AJAX and update the container.
You can add JavaScript to create the navigation bar on the fly for each page you want it on.

Angular Routing not working and not loading content in ng-view

Following is the folder structure I am using for my demo application
css
fonts
images
js
views
index.html
The code for index.html is as follows :
<!DOCTYPE html>

And here goes the code for controller.js :
var app = angular.module('myApp',['ngRoute']);
app.config(function($routeProvider){
$routeProvider
.when('/',{
templateUrl : 'views/home.html',
controller : 'homeCtrl'
})
.when('/first',{
templateUrl:'views/first.html',
controller : 'firstCtrl'
})
.when('/second',{
templateUrl:'views/second.html',
controller : 'secondCtrl'
})
.otherwise({
redirect :'/'
});
});
app.controller('homeCtrl',function($scope){
$scope.name="Angad";
});
app.controller('firstCtrl',function($scope){
$scope.name="Second";
});
app.controller('secondCtrl',function($scope){
$scope.name="Second";
});
Routing doesnt seems to work here .... The only error it shows is :
-Error: [$compile:tpload]
-XMLHttpRequest cannot load
Apart from this if anyone could help as to how to make the desired pages open in the ng-view section on the click of the top navbar buttons ...would be highly appreciated !!
Your code seems to be correct. If you are using chrome as a browser use a local webserver to test your site (for example lite-server). Chrome won't allow you to load local files for security reasons. You could also try and test your application with another browser.
Your Navbar hrefs should look like:
<li>About Us</li>
or if you are using AngularJS 1.6
<li>About Us</li>

Deactivating Bootstrap Navbar button using AngularJS

Here I have the code for a bootstrap navigation bar:
var cvApplication = angular.module('cvApplication', []);
cvApplication.controller('contentCtrl', function ($scope) {
$scope.navButtons = ["Home", "About", "Contacts"];
$scope.btnActive = "About";
});
<!DOCTYPE html>
<html lang="en" ng-app="cvApplication" ng-cloak ng-init="">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="style.css">
</head>
<body>
<nav class="navbar navbar-default navbar-static-top" ng-controller="contentCtrl">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#mainNavBarToggler">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
Subjects
</div>
<div class="collapse navbar-collapse" id="mainNavBarToggler">
<ul class="nav navbar-nav">
<li ng-repeat="navButton in navButtons" ng-class="{ active: btnActive == navButton }" ng-click="btnActive = navButton">
{{navButton}}
</li>
</ul>
</div>
</div>
</nav>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<script src="script.js"></script>
</body>
</html>
Everything works great, except for the fact that when you click one of the buttons on the navigation and then click another one, the previous one you clicked doesn't get deactivated (aka the 'active' class isn't removed aka it remains highlighted). How can I fix this?
You can use function in controller to update variable for active button.
var cvApplication = angular.module('cvApplication', []);
cvApplication.controller('contentCtrl', function ($scope) {
$scope.navButtons = ["Home", "About", "Contacts"];
$scope.btnActive = "About";
$scope.updateActive = function(navButton) {
$scope.btnActive = navButton;
};
});
<!DOCTYPE html>
<html lang="en" ng-app="cvApplication" ng-cloak ng-init="">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">

<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="style.css">
</head>
<body>
<nav class="navbar navbar-default navbar-static-top" ng-controller="contentCtrl">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#mainNavBarToggler">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
Subjects
</div>
<div class="collapse navbar-collapse" id="mainNavBarToggler">
<ul class="nav navbar-nav">
<li ng-repeat="navButton in navButtons" ng-class="{ active: btnActive == navButton }" ng-click="updateActive(navButton)">
{{navButton}}
</li>
</ul>
</div>
</div>
</nav>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<script src="script.js"></script>
</body>
</html>
Here is similar solution.
I don't know why it works with function, but don't work with interpolation in view. Possible, you get many local scopes in view.

Angular routing app working locally, not working on on plunker - ui-view not pulling in the views :(

So, I have an angular routing app working locally, but it's not working on plunker, I'm trying to get it working there to demonstrate an issue, but anyway... It's not working, and it doesn't make sense why. The views are not being injected into <div ui-view></div> on the index page :(
Here's my plunker
Here's the js:
var routerApp = angular.module('routerApp', ['ui.router','ui.bootstrap']);
routerApp.config(function($stateProvider, $urlRouterProvider, $locationProvider) {
$urlRouterProvider.otherwise('/home');
$locationProvider.html5Mode(false).hashPrefix("");
$stateProvider
// HOME VIEW ========================================
.state('home', {
url: '/home',
templateUrl: 'partial-home.html'
// onEnter: scrollContent
})
// ONE VIEW ========================================
.state('one', {
url: '/one',
templateUrl: 'partial-one.html'
})
// TWO VIEW ========================================
.state('two', {
url: '/two',
templateUrl: 'partial-two.html'
})
// THREE VIEW ========================================
.state('three', {
url: '/three',
templateUrl: 'partial-three.html'
})
});
Here's my index.html page (check the plunker above to see the view pages):
<!DOCTYPE html>
<html>
<head>
<!-- // base path for angular routing -->
<base href="/">
<!-- CSS -->
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">

</button>
<a class="navbar-brand" ui-sref="home">Some web page somewhere</a>
</div>
<div id="navbar" class="navbar-collapse collapse">

<!-- End Fixed navbar -->
<!-- MAIN CONTENT -->
<!-- Inject Content Here -->
<div class="container" style="padding-top:68px;">
<div ui-view></div>
</div>
</body>
There is updated plunker
In case of the plunker, we cannot use
<base href="/" />
Because there is always some stuff like 'http://run.plnkr.co/s6tfzR2Tbd1v9qB9gPH8/script.js' instead of the http://run.plnkr.co/script.js
also JQuery is needed for bootstrap, new head:
<head>
<!-- CSS -->
<script data-require="jquery#*" data-semver="2.1.4" src="http://code.jquery.com/jquery-2.1.4.min.js"></script>
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" />
<link rel="stylesheet" href="style.css" />
<!-- JS -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.4/js/bootstrap.min.js"></script>
<script src="http://code.angularjs.org/1.2.13/angular.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular-ui-router/0.2.8/angular-ui-router.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/0.13.0/ui-bootstrap-tpls.js"></script>
<script src="script.js"></script>
<!-- // base path for angular routing -->
<!--<base href="/" />-->
</head>
Check the working version here
The <base> tag is messing with plunker, remove it and it should work.

Bootstrap glyphicon error: square instead of icon

Your glyphicon span should have the following class: glyphicon glyphicon-align-justify as opposed to just glyphicon-align-justify
I would suggest not using align justify in the span as a class - just display the glyphicon and then justify it in an outside div.
<div class="text-justify">
<span class="glyphicon glyphicon-align-justify"></span>
</div>

Bootstraps toggle button does not open on click or touch on mobile button

i want to create a navigation bar in bootstrap
everything works fine except one. when ever I resize the browser to width of mobile and click on the toggle button the dropdown menu does not open.
Please help me. All I wanted is "when ever i click on the stacked toggel button i want the drop down to open".
I have also made changes to class as well as ids in data-toggle attribute of the button.
I have included jquery, bootstrap js and bootstrap css. I have displayed the entire code below:
