HTML
<html lang="en" ng-app="map" xmlns="http://www.w3.org/1999/xhtml">
<body>
<div ng-controller="topbarController as topbarCtrl">
<div ng-repeat="pages in topbarCtrl.topbar">
{{pages.page}}
</div>

</html>
ANGULAR
app.controller('topbarController', ['$http', function($http) {
var topbar = this;
topbar.pages = [];
$http.get('/Hexdra/app/app_data/pages.json').success(function(data){
topbar.pages = data;
});
}]);
JSON
[
{ "page": "about_me"},
{"page": "index"}
]
I am trying to display a list of pages by using ng-repeat and loading the page data from a JSON through an http.get. My problem is that nothing is displayed on the html page when it is loaded.
I checked this but couldn't seem to get that fix to work.
I am also having a hard time keeping track of all the different names.
1.) I know that my controller is called topbarController. In the HTML the controller scope is then renamed to topbarCtrl.
2.) I then have angular index through my pages object and inside its own div it displays every page.
Fixes are appreciated but also further reading to what has gone wrong would also be appreciated.
Thank you!
I had to look over your code a few times, but the issue is in the following line:
<div ng-repeat="pages in topbarCtrl.topbar">
You assigned topbar to this in your controller:
var topbar = this;
topbar.pages = [];
Change your ng-repeat to this, and it will work
<div ng-repeat="pages in topbarCtrl.pages">
try this
app.controller('topbarController', ['$http', function($http) {
$scope.topbar {
topbar.pages : []
};
$http.get('/Hexdra/app/app_data/pages.json').success(function(data){
$scope.topbar.pages.push(data);
});
}]);
and your html must be like this:
<div ng-repeat="page in topbarCtrl.pages">
{{page}}
</div>
Are you sure that the url that you are giving is proper?
for example it should be like http://localhost:80/Hexdra/app/app_data/pages.json
Try using the absolute url and see if it works

I know there are other questions about this, but I already tryed and nothing seems to work.
I basically have an angular variable retrieved from an $http.get .
The content is html encoded, like:
Paperwhite – Human Nature
So I have to display it as
<div ng-bind-html="songrel.title.rendered"></div>
To render the html:
Paperwhite – Human Nature
I want to split this value for the - and display only
Human Nature
I tryed something like
<div ng-bind-html="songrel.title.rendered.split('–')[1]"></div>
or
<div ng-bind-html="songrel.title.rendered.split('-')[1]"></div>
Or moving the code in my app.config
$scope.showFirstBr = function(content){
return content.split('–')[1]
};
and then
<div ng-bind-html="showFirstBr(songrel.title.rendered)"></div>
but nothing seems to work. What am I missing?
Try this
var app = angular.module("MyApp", []).controller("MyCtrl", function($scope, $sce) {
var str = 'Paperwhite – Human Nature';
$scope.test = $sce.trustAsHtml(str.split('–')[1]);
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="MyApp" ng-controller="MyCtrl">
<div ng-bind-html="test"></div>
</body>
I've fixed adding this in the controller:
$scope.showFirstBr = function(content){
var c = content.replace('–','-');
return c.split('-')[1]
};
I'm trying to develop a solution through AngularJS where when the user changes the profile image, all other photos based on their profile are also changed.
How can I start developing this feature?
Thanks in advance!
[Solution]
With the help of the #wolfman6377, I can understand the functionality and develop the solution for what I need. I'll leave an example in CodePen.
CodePen
var myApp = angular.module('myApp',[]);
myApp.controller('myController', function() {
this.myVar = 'https://robohash.org/asd'
this.updatePicture = function() {
this.myVar = 'https://angular.io/resources/images/logos/angular/angular.png';
};
});
Thank you, #wolfman6377.
You are using a jQuery-like strategy. jQuery element selector will not be able to change the value of myVar.
I would recommend going through some basic tutorials on angular1. But in a nutshell, you need to:
Do not grab elements and change attributes
add a module to the ng-app value
Use ng-controller in the template
Add ng-click to the button to update the value of myVar
template
<body ng-app="myApp">
<div id="var" ng-controller="myController as vm">
<img ng-src={{vm.myVar}} />
<button ng-click="vm.updatePicture()">Click me</button>
</div>
</body>
controller:
angular
.module('myApp', [])
.controller('myController', function() {
this.myVar = 'https://www.w3schools.com/angular/pic_angular.jpg'
this.updatePicture = function() {
this.myVar = 'https://angular.io/resources/images/logos/angular/angular.png';
};
});
angular-material newbie here. I'm trying to hide some elements in our site using a switch, as instructed by our client. This led me to angular-material's md-switch.
So I tried incorporating it like so...
<md-switch md-no-ink aria-label="switchView" ng-model="switchView">{{switchView}}</md-switch>
And called the value of the switch in my element like this:
<img ng-src="{{photoPath}}" class="profilePic" ng-hide="switchView"/>
After testing it though, it didn't hide my <img> even though my switchView changed its value. Am I missing something here?
Other methods I've tried:
Adding ng-change to my md-switch, which called a function that would equate another variable (e.g. $scope.toggleView = $scope.switchView) with switchView's value. $scope.toggleView would then be used in my ng-hide.
ng-hide = "switchView == true".
Any advice would be very much appreciated. Thank you.
UPDATE 1: To test it, I tried hiding the <div> beside my <md-switch> and it worked perfectly. However it's still not working with my <img>.
Further checking revealed that it was inside a <nav> element. However they're both using the same controller. I wonder if that's the problem? I assumed that it shouldn't be a problem because of this.
The structure is like this:
<nav ng-controller="MainController">
<!-- other navigation elements here -->
<img ng-src="{{photoPath}}" class="profilePic" ng-hide="switchView"/>
</nav>
<div ng-controller="MainController">
<div>Toggle Switch</div>
<md-switch md-no-ink aria-label="switchView" ng-model="switchView">{{switchView}}</md-switch>
</div>
UPDATE 2: I've added the following code in my JS file because there are plans to hide elements in other pages. It still didn't work.
$scope.onChange = function(value) {
$scope.$broadcast("view_mode", $scope.switchView);
}
$scope.$on("view_mode", function(event, switchValue) {
$scope.viewThis= switchValue;
});
My HTML now looks like this:
<img ng-src="{{photoPath}}" class="profilePic" ng-hide="viewThis"/>
As for the controller, ngMaterial was called in a separate JS file (our main), together with all our dependencies and configs. Hence, this wasn't called inside MainController.
mainApp.js
var app = angular.module('myAppModule', [
// other references here
'ngMaterial'
]);
mySample.js
angular
.module('myAppModule')
.controller('MainController', ['$scope', function ($scope) {
// functions etc. go here
Hope this helps clear things up. Thank you.
Try something like this, its a trivial example but hope it helps. Here's a link to working codepen.
There seems to be a couple ways you could handle this according to the docs:
Angular Material- MD-Switch
function exampleController($scope) {
$scope.secondModel = false;
$scope.onChangeEvent = function(value) {
$scope.imgSource = (value) ? 'http://www.fillmurray.com/300/200' : 'http://www.fillmurray.com/g/155/300';
};
// alternatively: you could set the ternary to empty string value here.
}
angular
.module('BlankApp', ['ngMaterial'])
.controller('exampleController', exampleController);
<md-switch ng-model="switchValue" ng-change="onChangeEvent(switchValue)">
<img ng-src="{{imgSource}}" alt="" />
</md-switch>
<md-switch ng-model="secondModel">
<img src="http://www.fillmurray.com/300/200" alt="" ng-hide="secondModel" />
</md-switch>
Thank you to everyone who gave their inputs. After some research, I managed to solve this problem using factories (source).
I'm sharing my solution so that it may help others who experience the same problem.
HTML:
<nav ng-controller="MainController">
<!-- other navigation elements here -->
<img ng-src="{{photoPath}}" class="profilePic" ng-hide="switchView"/>
</nav>
<div ng-controller="MainController">
<div>Toggle Switch</div>
<md-switch md-no-ink aria-label="switchView" ng-model="switchView" ng-change="onChange(switchView)">{{switchView}}</md-switch>
</div>
JS:
angular
.module('myAppModule')
.controller('MainController', ['$scope', 'ViewModeFactory', function ($scope, ViewModeFactory) {
// functions etc. go here
// For client presentation mode
$scope.onChange = function(value) {
ViewModeFactory.setViewMode($scope.switchView);
}
$scope.$watch(function (){
$scope.switchView = ViewModeFactory.getViewMode();
});
}])
.factory('ViewModeFactory', function () {
var data = {isViewMode: ''};
return {
getViewMode: function () {
return data.isViewMode;
},
setViewMode: function(value) {
data.isViewMode = value;
}
};
});
I used factories so that other controllers in our site can use the value passed by md-switch.
Hope this helps.
Have a template that I'd like to load using ng-include and assign a controller instance to. This new template/scope/controller needs to be loaded in response to a user interaction (hover or click).
The content of the template has to be set using element.innerHTML because the content is set by a 3rd party.
The user can then click out of the new div and I would like to destroy the controller/scope that was created.
Pseudocode for what I want to achieve:
popup.setContent("<div ng-controller='PopupController'><div ng-include=\"views/LayerPopup.html\"></div></div>");
How do I tell angular to process the ng-include and ng-controller just as though the page was being loaded for the first time?
Thanks!
Edit:
Add plunker to illustrate question
http://plnkr.co/edit/DPuURCoq2hJ0LCLIN2dc?p=preview
http://jsfiddle.net/ADukg/5420/
Not using ngInclude, but it does fill these criteria:
You pass in a templateURL.
Pass in the name of the controller you would like to use.
Pass in the third party content (which in turn gets set with $element.innerHTML).
Setup a click listener someplace outside the $scope of the popup, which triggers a kill command on the popup.
This is how I imagine you would instantiate it:
<directive tpl="tpl.html"
ctrl="DirectiveController"
third-party-content="{{thirdPartyContent}}">
</directive>
Not sure this will suit you, but I had a fun time putting it together and maybe it'll prove useful to someone else.
In any case, I have to agree with the comments you've recieved so far. It's a bit cryptic as to what you have to work with right now and what possible options are available to you.
Here is a plunker of what you are trying to do. If you click on a button, a popup will show a template, and you can click on the template and it will stay up, but if you click out of it, it will get removed.
HTML
<body ng-controller="MainCtrl" ng-click="closePopup()">
<button ng-click="openPopup($event)" id="clicktarget">Click</button>
<p>Hello {{name}}!</p>
<div ng-include="getPopup()" ng-click="$event.stopPropagation()">
</div>
<script type="text/ng-template" id="theTemplate.html">
<div ng-controller="PopupController">
<div ng-include="'LayerPopup.html'"></div>
</div>
</script>
</body>
JS
angular.module('plunker', [])
.controller('MainCtrl', function($scope, $templateCache) {
$scope.name = 'World';
$scope.popupTmpl = null;
$scope.openPopup = function($event){
$scope.popupTmpl = 'theTemplate.html';
$event.stopPropagation();
};
$scope.getPopup = function(){
return $scope.popupTmpl;
};
$scope.closePopup = function(){
$scope.popupTmpl = null;
};
})
.controller('PopupController', ['$scope', function($scope) {
$scope.aVariableMaybe = 'lulz something';
}]);
On a side note, try to get rid of that JQuery stuff when you are using Angular. Angular can do everything on its own
I am new to Angular.js. I currently have the following html code, where I define my div with my file html ( ng-include ) and my controller ( ng-controller ):
<div id="customerinformation-maxi" ng-include="'pages/customerinformation-maxi.html'" ng-controller="customerInformationMaxiController" class="col-md-12"></div>
This is the html code for the called html in directive ng-include ( customer-information.html ):
<div class="row">
<div class="col-md-2">
<span>Customer Number</span>
<span>{{customer.number}}</span>
</div>
<div class="col-md-2">
<span>Portfolio</span>
<span>{{custom.portfolio}}</span>
</div>
</div>
This is the js controller:
angularRoutingApp.controller('customerInformationMaxiController', function($scope, $http) {
//Here i need to load the model variable with a literal text {{customer.number}} and {{customer.portfolio}}, how could do it? using scope object? with a json file?
});
Here I need to load the model variable with a literal text {{customer.number}} and {{customer.portfolio}}.
How could do it? Using scope object? With a json file?
Thanks for any help.
Yes, you should do it using the $scope object.
To get a general overview, here is a hello-world example:
<div ng-controller="HelloController">
{{ helloMessage }}
</div>
And in you controller's code (js file or script tag into the html):
var myApp = angular.module('myApp',[]);
myApp.controller('HelloController', ['$scope', function($scope) {
$scope.helloMessage= 'Hello World!';
}]);
But I foresee some nesting in the provided snippet of your question, so you 're probably dealing with a collection of objects which means that you have to iterate through it, in the html part, using the ng-repeat directive, like:
<tr ng-repeat="customer in customers>
<td>{{customer.number}}</td>
<td>{{customer.portfolio}}</td>
</tr>
So, your controller's functionality should contain the customers object, like:
angularRoutingApp.controller('customerInformationMaxiController', function($scope, $http) {
var customers=[
{
number:'123',
portfolio: 'blah blah'
},
{
number:'124',
portfolio: 'blah blah'
},
{
number:'125',
portfolio: 'blah blah'
}
];
});
For further reference, you could read two respective example I have written:
Angular.js Controller Example
Angular.js JSON Fetching Example
The second one is only to see a sample usage of traversing collections, it is not meant that you have to use json, as you stated in your question; but I see that you also defined the $http service in your controller, so if it's about data that are going to be fetched from a remote destination, the JSON Fetching Example should probably help you better).
You should use scope objects to give values to your modal variables.
angularRoutingApp.controller('customerInformationMaxiController', function($scope, $http) {
$scope.customer.number = 'sample number';
$scope.customer.portfolio = 'sample portfolio';
});
