I have some HTML which looks like this:
<body ng-controller="main">
<div id="main">
<div ng-view></div>
</div>
</body>
Here is the controller:
var app = angular.module('buildson', ['ngRoute', 'ngAnimate']);
app.controller('main', function($scope) {
$scope.$on("$routeChangeSuccess", function (event, currentRoute, previousRoute) {
window.scrollTo(0, 0);
});
});
And here is the Routing:
//ROUTING
app.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl : 'home.html'
})
.when('/courses', {
templateUrl : 'views/coursesTeaching.html'
});
});
Here is coursesTeaching.html
<div class="coursesList">
[Display a list of courses here]
Display Documentation
</div>
And here is documentationWidget.html
Documentation Content is in this file
What I want to do is when they click on this link Display Documentation It loads the documentationWidget.html content into the <div class="documentationWidget"></div> spot, I suppose it is a view within a view or a sub-route. I can't do it with jQuery Ajax or anything because I want to be able to use Angular variables inside of the loaded html file.
Take a look at ui-router as an alternative to ngRoute. This has good support for nested views amongst other things: https://github.com/angular-ui/ui-router
This has also been discussed in more detail here: Difference between ng-route & ui-router
I've been told you should use the third-party library ui-router for complex routing operations.

ui-router and ngRoute at the same time
I'm working on a quite large project that uses very old angularjs (version 1.4.3) along with ui-router (version 0.2.15). Updating to newer version at the moment it's not possible.
The app use simple state-routing.
What I succesfully tried to achieve was to open a modal (ui.bootstrap) with a sub-routing within.
First I tried to use ui-router only, but the ui-router do not recognize ui-view inside modal template so it not worked.
After that I tried to use ui-router for normal navigation only and ngRoute for managing the routing inside the modal and it worked.
My question is if the use of both ui-router and ngRoute could cause side-effects or other hard-to-detect issues.
Here is a Plunker with a my test app.
Plunker
angular.module('router_app', ['ui.router', 'ui.bootstrap', 'ngRoute'])
.config(function ($stateProvider, $routeProvider) {
$stateProvider
.state('my_state', {
url: '/my_state',
views: {
'my_view': {
templateUrl: '/templates/my_state.tpl',
controller: 'ctrl_my_state'
}
}
});
$routeProvider
.when("/my_state/my_modal", {
templateUrl: "/templates/my_modal.tpl",
controller: "ctrl_my_modal"
})
.when("/my_state/my_modal/my_modal_a", {
templateUrl: "/templates/my_modal_a.tpl",
controller: "ctrl_my_modal_a"
})
.when("/my_state/my_modal/my_modal_b", {
templateUrl: "/templates/my_modal_b.tpl",
controller: "ctrl_my_modal_b"
});
})
.run(function ($state) {
$state.go("my_state");
})
my_modal.tpl
<div ng-controller="ctrl_my_modal">
MODAL
<button ng-click="closeModal()">close</button>
<button ng-click="gotoA()">goto a</button>
<button ng-click="gotoB()">goto b</button>
<div ng-view></div>
</div>
index.html
<html ng-app="router_app">
<body>
<div ui-view="my_view"></div>
</body>
</html>
I continued trying to not use two different routers at the same time and finally I came up with a working solution.
It is based on this. I was running around the solution for some time, but finally I've got it working as I wanted.
Here is my final test app.
I am currently creating an app that has a nav bar. I want a particular function to be invoked every time the submit button in the nav bar is pressed regardless of route/view. I am having trouble because here in my routes file I have created associations that changed based on route. The form is found in <form class="pure-form" ng-submit="somefunc()">
routes.js
angular.module('LiveAPP', ['ngRoute',
'LiveAPP.main',
'LiveAPP.signUp',
'LiveAPP.artist'])
.config(function($routeProvider, $httpProvider) {
$routeProvider
.when('/', {
templateUrl : '/home.html',
controller : 'mainCtrl'
})
.when('/signup',{
templateUrl : '/signup.html',
controller : 'signUpCtrl'
})
.when('/artist',{
templateUrl : '/artistpage.html',
controller : 'artistCtrl'
})
})
index.html
<body ng-app='LiveAPP'>
<div class="header">
<form class="pure-form" ng-submit="somefunc(field)">
<input ng-model="field" type="text" placeholder="Artist" name="field">
<button type="submit">Search</button>
</form>
Sign Up
artistPage
</div>
<div ng-view></div>
</body>
mainCtrl
angular.module('LiveAPP.main',[])
.controller('mainCtrl', ['$scope','$http', '$location',mainCtrl]);
function mainCtrl($scope,$http,$location){
$scope.somefunc = function(searchvalue){
console.log(searchvalue)
}
};
Right now the submit button is associated with the mainCtrl which is related to the home.html. Any ideas?
In general you have a couple approaches:
If you need some logic to be available in more than one controller you can create a service and inject it to your controllers.
You can implement controller inheritance.
There are a couple ways to implement controller inheritance.
This is one example of how to do that:
var app = angular.module('myApp', []);
app.controller('MainCtrl', function() {
this.methodclick=function(){
alert('I am Parents')
}
});
app.controller('ChildCtrl', function($controller) {
var ChildCtrl=this;
ChildCtrl.child = $controller('MainCtrl',{});
});
But in my opinion it is better to implement a service.
I have controller with method that does AJAX request:
.controller('EditProfileController', ['$scope', '$http') {
// Do AJAX query here
// Some methods for update profile
}]);
Also I have $routeProvider in this Angular JS file:
.config(function ($routeProvider) {
$routeProvider
.when('/profile/personal/:type', {
templateUrl: '/personal.html',
controller: 'EditProfileController'
})
}
Problem is that when I open page with URL /profile/personal/:type it calls again controller EditProfileController and calls AJAX method inside.
How I can fix it?
HTML code:
<div ng-controller="EditProfileController">
<!-- Here are loaded data from AJAX response
</div>
Solution:
Problem was in double ng-view in template:
<div ng-show="isLoaded" ng-view></div>
<div ng-show="!AILoading" ng-view></div>
Simply remove the ng-controller directive from the HTML as the router is already taking care of this
I want to two way bind with ng-model directive AFTER the ngview has loaded. Is this possible?
app.js
app.controller('FormController', function($scope) {
$scope.data = {
header = 'Header',
}
});
index.html
<div ng-controller="FormController">
Header: <input type="text" ng-model="data.header"> {{data.header}}
</div>
Which works fine. What I want to do is do the exact same thing after ng-view
within ng-view I would put
{{data.header}}
and it would say "Header" but does not bind the data.
Hopefully I explained the problem clearly. Any ideas?
here is a working example
In your script:
declare ngRoute as a dependency
use $routeProvider inside a config block to declare your routes
I use inline template only for simplicity (In real apps I use templateUrl)
var app = angular.module('app',['ngRoute']);
app.config(function($routeProvider){
$routeProvider.when('/',{
template: "Header: <input type='text' ng-model='data.header'> {{data.header}}",
controller: "ctrl"
});
});
app.controller('ctrl',function($scope){
$scope.data = {
header : 'Header'
};
});
In your html:
Add angular-route.js to your scripts
Add a ng-view directive
I would like to change the background image of the application(Html Body) based on the url. And this I want to do in angularJS only :)
For eg:
1) if user visits the url like this,
www.domain.com/view1
Bellow image is shown
2) If user visits url
www.domain.com/view2
I want show other image
app.js
var app = angular.module('app', []);
app.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/view1', {templateUrl: 'partials/partial1.html', controller: 'MyCtrl1'});
$routeProvider.when('/view2', {templateUrl: 'partials/partial2.html', controller: 'MyCtrl2'});
$routeProvider.otherwise({redirectTo: '/view1'});
}])
app.config(['$locationProvider', function($locationProvider) {
$locationProvider.html5Mode(true);
}]);;
Controler.js
app.controller('MyCtrl1',function($scope){
$scope.viewBackground="body"
console.log($scope.viewBackground);
})
app.controller('MyCtrl2',function($scope){
$scope.viewBackground="profile"
})
in the partial html, I am just doing like this
<div class="span12">
<p>
{{$scope.viewBackground}}zxz
</p>
</div>
But some reason I am not able to get the value of viewBackground property value.
I'm not sure I understand you correctly, but I hope so.
You have 2 options.
First - use different controllers for each page view1 and view2.
And use ng-class directive on the pages:
HTML:
<!-- "page" View 1 -->
<div ng-controller="View1Ctrl">
<div ng-class="viewBackground"> View 1 </div>
</div>
<!-- "page" View 2 -->
<div ng-controller="View2Ctrl">
<div ng-class="viewBackground"> View 2 </div>
</div>
JS:
var app = angular.module('app', []);
function View1Ctrl($scope) {
$scope.viewBackground = "background-small"
}
function View2Ctrl($scope) {
$scope.viewBackground = "background-big"
}
On your CSS:
.background-small{
height:200px;
width:200px;
background: url('...img1...');
}
.background-big{
height:400px;
width:400px;
background: url('...img2...');
}
Second option - use .run block, where you will add some logic to change the bg-image, but this is a poor option
If your controller you can check the $routeParams param and then set a scope variable to control the background image.
function announcements_detail_controller($scope, $rootScope, $routeParams, $http, $location)
{ //console.log($routeParams);
$scope.css_class_for_background_image = 'xxxx';//
}
