I have an ionic & angular based project. I get variable node from a service. node's body value is HTML. But when I print {{node.body.und[0].value}} with ionic, it prints HTML codes with tags like <ul><li><strong>Title:</strong> some text</li><ul>
Controller and service part of the code:
.controller('NodeCtrl', function($scope, $stateParams, Node) {
$scope.node = Node.get({nid: $stateParams.nid});
});
.factory('Node', function ($resource) {
return $resource('some-domain.com/api/node/:nid'+'.json');
})
Ionic template:
<ion-view view-title="{{node.title}}">
<ion-content>
<div class="list card">
<div class="item">
<h2>{{node.title}}</h2>
</div>
<div class="item item-body">
{{node.body.und[0].value}}
</div>
</div>
</ion-content>
</ion-view>
How can I make ionic print {{node.body.und[0].value}} as HTML instead of with HTML tags like <ul><li><strong>Title:</strong> some text</li><ul>?

ng-bind-html, is what you are looking for.
From the Docs, use the ng-bind-html in the view as:
<div ng-controller="ExampleController">
<p ng-bind-html="myHTML"></p>
</div>
and in the controller, assign the scope variable with the html content as:
angular.module('bindHtmlExample', ['ngSanitize'])
.controller('ExampleController', ['$scope', function($scope) {
$scope.myHTML =
'I am an <code>HTML</code>string with ' +
'links! and other <em>stuff</em>';
}]);

My question is best explained when I straight go to the code.
HTML part:
<div class="panel panel-default post" ng-repeat="post in posts">
<div class="panel-body">
<div class="row">
<div class="col-sm-2">
<a class="post-avatar thumbnail" href="/profile#/{[ post.profileID ]}">
<div class="text-center">{[ user.fullname ]}</div>
</a>
</div>
</div>
</div>
When I click on the /profile#/{[ post.profileID ]} link - it takes me to the profile page. All good here.
However, I am using ngView so I have separated it like this:
<div class="col-md-3">
<div>Some HTML stuff</div>
</div>
<div class="col-md-6">
<div ng-view></div>
</div>
<div class="col-md-3">
<div>Some HTML stuff</div>
</div>
My ngView makes use of the /profile#/{[ post.profileID ]} param and I use it to display whatever I have to display.
The problem:
I can get the profileID param in my angular controller but once I get it, how will I be able to pass it onto other controllers?
My controller looks like the below:
var profileApp = angular.module('profileApp', ['ngRoute']);
profileApp.config(function($routeProvider) {
$routeProvider
.when('/:id', {
templateUrl : 'partial/profile/feed.html',
controller : 'mainController'
})
.when('/posts:id', {
templateUrl : 'partial/profile/posts.html',
controller : 'postsController'
});
});
profileApp.controller('mainController', ['$scope', '$http', '$routeParams', function($scope, $routeParams){
console.log($routeParams.id);
}]);
profileApp.controller('postsController', ['$scope', '$routeParams', function($scope, $routeParams){
console.log($routeParams.id);
}]);
As you can see, I get get the param passed from the HTML link and use it in the mainController but how will I get the param to be a link in the col-md-3 (just like the original /profile#/{[ post.profileID ]})?
Hope this makes sense. It's has been driving me nuts!
Thanks
Why don't you just edit your partial HTML pages and put the columns in it.
For partial/profile/feed.html :
<div>
<div class="col-md-6">
<div>feed stuff</div>
</div>
<div class="col-md-3">
</div>
</div>
And partial/profile/posts.html could be :
<div>
<div class="col-md-6">
</div>
<div class="col-md-3">
<div>posts stuff</div>
</div>
</div>
So I did some research into this and I just ended up using services.
See below for the answer:
profileApp.service('globalParams', function() {
var profileID = '';
return {
getProfileID: function() {
return profileID;
},
setProfileID: function(value) {
profileID = value;
}
};
});
You then pass the service into the dependencies in the controllers, like below:
profileApp.controller('mainController', ['$scope', 'globalParams', function($scope, globalParams){
//some code
};
And you can call the functions for getting and setting the variables.
I have a HTML page with different sections, which are loaded with AJAX. I have created a controller for each of the sections.
How is possible to bind the controller on a section which has been dynamically added on HTML?
I have found very complicated solutions, which i don't even know if they apply.
I need the most basic, easiest solution, something similiar with ko.applyBindings($dom[0], viewModel) for the ones who worked with KnockoutJs.
Index html
<div class="row" ng-app="app">
<div class="col-xs-3">
<ul class="nav nav-pills nav-stacked">
<li>
Profile
</li>
</ul>
</div>
<div class="col-xs-9">
<div id="container"><!-- load dynamic HTML here --></div>
</div>
</div>
Dynamic HTML
<div ng-controller="profile">
First Name: <input type="text" ng-model="firstName"><br>
Last Name: <input type="text" ng-model="lastName"><br>
<br>
Full Name: {{firstName + " " + lastName}}
</div>
Javascript:
var app = angular.module('app', []);
app.controller('profile', function ($scope) {
$scope.firstName = "John";
$scope.lastName = "Doe";
});
// load new HTML
// normally this is triggered by a link / button
$(function () {
$.get("/EditProfile/Profile", function (data, status) {
$("#container").html(data);
});
});
Don't use jQuery to embed html to your container. If you use jQuery, AngularJS can't track DOM manipulations and trigger directives. You can use ng-include directive of AngularJS.
In index.html file:
...
<div id="container">
<div ng-include="'/EditProfile/Profile'"></div>
</div>
...
If you want you can make that conditional:
...
<div id="container">
<div ng-if="profilePage" ng-include="'/EditProfile/Profile'"></div>
</div>
...
With that example, if you set profilePage variable to true, profile html will be load and render by ng-include.
For detailed info take a look to ngInclude documentation.
By the way, best practice to include views to your layout by triggering same link clicks is using routers. You can use Angular's ngRoute module or uiRouter as another popular one.
If you use ngRoute module, your index.html looks like that:
<div class="row" ng-app="app">
<div class="col-xs-3">
<ul class="nav nav-pills nav-stacked">
<li>
Profile
</li>
</ul>
</div>
<div class="col-xs-9">
<div id="container" ng-view><!-- load dynamic HTML here --></div>
</div>
</div>
And with a router configuration like below, profile html will be automatically loaded and rendered by ngRoute inside ngView directive:
angular.module('myapp', []).config(function($routeProvider) {
$routeProvider
.when('/profile', {
templateUrl: '/EditProfile/Profile',
controller: 'ProfileController'
});
});
Alright, I have an html page that contains an ionic card but when I bind data to its items they are not shown at the browser so what is the problem
<ion-view title="Game" ng-controller="GameCtrl as vm">
<ion-content class="has-header">
<div class="card">
<div class="item">
Home Team
</div>
<div class="item">
{{vm.game.team1}}
</div>
<div class="item">
Score: {{vm.game.team1Score}}
</div>
</div>
<div class="card">
</div>
<div class="card">
</div>
</ion-content>
</ion-view>
and here is the angular controller for this page :
(function () {
'use strict';
angular.module('eliteApp').controller('GameCtrl', ['$stateParams','eliteApi', GameCtrl]);
function GameCtrl($stateParams, eliteApi) {
var vm = this;
var gameId = Number($stateParams.id);
var data = eliteApi.getLeagueData();
vm.game = _.find(data.games,{"id": gameId});
};
})();
I injected the js file to index.html; while tracing the debugging the function is getting data but data is not viewed at the browser so can anybody have some help ?
Try this:
'use strict';
angular.module('eliteApp').controller('GameCtrl', ['$stateParams','eliteApi', function($stateParams, eliteApi){
var gameId = Number($stateParams.id);
var data = eliteApi.getLeagueData();
this.game = _.find(data.games,{"id": gameId});
}]);
Edit
Looks like you're missing a route with a game id. Add this to your .config function:
.state('app.game-detail', {
url: "/game/:id",
views: {
"mainContent":{
templateUrl: "app/game/game.html"
}
}
})
And change your team-detail.html with this:
<a class="item item-icon-right" ng-repeat="game in vm.games"
href="#/app/game/{{game.gameId}}">
It should work now.
How can I store values to variable for example on click in angular? I have the following code which doesn't save the value into variable:
HTML:
<div ng-app='app'>
<a ng-controller="MyController" href="#" ng-click="variable = 1">
</a>
{{variable}}
</div>
Controller:
var app = angular.module('app',[]);
app.controller('MyController', function($scope)
{
});
jsfiddle code
Your variable binding {{variable}} should be inside controller's scope. So move ng-controller to an element that will contain variable binding.
You need to initialize the variable. See http://plnkr.co/edit/dmSNVJ3BGIeaWaddKtZe
<body ng-app="">
<button ng-click="count = 1" ng-init="count='not set'">
Increment
</button>
<span>
count: {{count}}
</span>
</body>
Use a function to set the variable:
HTML:
<div ng-app='app'>
<a ng-controller="MyController" href="#" ng-click="setVariable()">
</a>
{{variable}}
</div>
Controller:
var app = angular.module('app',[]);
app.controller('MyController', function($scope)
{
$scope.setVariable = function() {
$scope.variable = 1;
}
});
Your syntax is correct, what went wrong is you put your controller declaration in the wrong place.
You just need move it to the outer layer, no need for ng-init or function (but might be a better practice):
<div ng-app='app' ng-controller="MyController">
<a href="#" ng-click="variable=1">
click me!
</a>
{{variable}}
</div>

newbie question: How can i pass a value from my HTML back to the Controller code:
FOr example, I want to pass the value '1234' to my js code.
<div ng-app="Test">
<div ng-controller="myCntlr">
<div ng-model="myModel" value="1234">
{{outputVal}}
</div>
</div>
</div>
JS controller:
test.controller('myCntlr', function ($scope, $filter) {
// access the value '1234' here ?
});
Thanks!
