Parse HTML from JSON in ng-repeat - javascript

I started to learn AngularJS today and so far I am doing well. But I encountered a problem and I can't seem to find an answer. What I'm trying to do is to print html string <p>Text</p> as formatted Text. So far Angular prints it as plain <p>Text</p>.
My code is as follows:
JS
var blogApp = angular.module('blogApp', []);
blogApp.controller('blogPostsCtrl', function($scope, $http) {
$http.get('wp-json/posts').success(function(data) {
$scope.posts = data;
$scope.postsLoaded = 'visible-lg';
});
});
HTML
<article id="post-{{post.ID}}" <?php post_class(); ?> itemscope itemprop="blogPost" itemtype="http://schema.org/BlogPosting" ng-repeat="post in posts" ng-class="postsLoaded">
<h2 class="entry-title" itemprop="headline"><a title="Link do {{post.title}}" rel="bookmark" href="{{post.link}}">{{post.title}}</a></h2>
<div class="entry-content">
<img ng-src="{{post.featured_image.source}}">
{{post.content}}
</div>
<footer class="entry-footer">
<ul class="categories"><li ng-repeat="category in post.terms.category">{{category.name}}</li></ul>
</footer>
</article>
My problem is with {{post.content}}. I wanted to try ng-bind-unsafe, but it was removed. I also tried ng-bind-html="post.content", but it didn't work.
I am using Angular 1.4.

You are looking for ngBindHtml. For example with your content you'd use this:
<div ng-bind-html="post.content"></div>
Evaluates the expression and inserts the resulting HTML into the element in a secure way. By default, the resulting HTML content will be sanitized using the $sanitize service. To utilize this functionality, ensure that $sanitize is available, for example, by including ngSanitize in your module's dependencies (not in core Angular). In order to use ngSanitize in your module's dependencies, you need to include "angular-sanitize.js" in your application.

ng-controller within an include that is within another controller potential scope issue

I am using node and angularjs. I have a frame like page inside an ejs that is passed content to load into the includes dynamically.
<div ng-app="thisApp">
<div ng-controller='MainCtrl'>
{{ firstMessage }}
<div id='contentFromNode' ng-include='<%= pageContent %>'></div>
</div>
</div>
<script>
var thisApp = angular.module('thisApp', []);
thisApp.controller('MainCtrl', [ '$scope', function($scope) {
$scope.firstMessage = "Main Controller Working Fine";
}])
</script>
and then the passed content might be just an html page containing something like this:
<div ng-controller='NestedCtrl' id='content-type-container'>
{{ nestedMessage }}
</div>
<script>
thisApp.controller('NestedCtrl', [function(){
var nested = this;
nested.nestedMessage = "Nested Won't Work";
}])
</script>
So I have tried $scope within the NestCtrl instead of referencing this, I have tried moving the script tag above and below (ideally this get separated eventually anyway). I have tried aliasing the controllers, however my problem is the in registration of the controller itself as I get that great Error: [$controller:ctrlreg] error. The page is loading the content fine? Any ideas what I am doing wrong here?
Seems JQlite doesn't support this. You have to include jquery or lazy load the script. Refer

passing href link through angularjs ng-repeat

I have an array of messages
$scope.messsages = []
Upon clicking a button the content of a text area gets added into the array using ng-click method.This message is used to query the api. After which we get a response from the server which too is added into the array $scope.messages. All these messages are shown in html using ng-repeat i.e:-
<div ng-repeat="msg in messages track by $index">
{{ msg }}
</div>
However if I get a response from the server as a hyperlink string like
To know more click here.
The message that gets displayed in ng-repeat is a plain string with no hyperlinks. It renders the <a href="URL"> part as a string itself. I would like to represent it in html format.
One way it worked was by using
document.getElementById("demo").innerHTML = $scope.messages;
But I would like to know is there any angular way to do so in the ng-repeat part itself.
Thanks in advance
Include ngSanitize module on your app and then change your view as below
<div ng-repeat="msg in messages track by $index">
<div ng-bind-html="msg"></div>
</div>
Try to use like this
<div ng-repeat="msg in messages track by $index">
<div ng-bind-html="msg"></div>
</div>
Here is the plunk example for it.
You should use ng-bind-html for this. so you should inject ngSanitize in your app.
$scope.html = 'test';
$scope.trustedHtml = $sce.trustAsHtml($scope.html);
angular.module('myapp', ['ngSanitize'])
.controller('main', function($scope,$sce) {
$scope.messages = [{"link":"<a href='#/abc'>abc</a>"}];
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.0/angular.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.1/angular-sanitize.min.js"></script>
<div ng-app="myapp" ng-controller="main">
<div ng-repeat="msg in messages">
<div ng-bind-html="msg.link"></div>
</div>
</div>

'Echo' html from string in angularjs when the string is on a template

I am using ionic tinder cards and each new card should be inserted in an predefined array as an object, likewise:
{text: "some_text"}
However, I might be getting html in the string and I want that html to be rendered. How can I do this considering the object above goes to a predefined array, something happens on the ionic code and then I inject it like this?
<div class="card">
{{card.text}}
</div>
use ng-bind-html directive: may be require import the sanitize module
<div class="card">
<span ng-bind-html="card.text"></span>
</div>
You should use ng-bind-html
<div class="card">
<span ng-bind-html="card.text"></span>
</div>
If your HTMl contains potentially dangeorus tag (like script tag), you should sanitize it before

ng-include dont work on ng-show

I have a simple angular app but the template is growing. I want to split it and use the ng-include directive but I can't get it to include correctly.
current template.html
<div class="edit-object-form" ng-show="editable">
<!-- ... -->
</div>
<div class="list-objects" ng-show="!editable">
<!-- ... -->
</div
desired template.html
<div class="edit-object-form" ng-show="editable">
<div ng-include="/partials/edit_objet_form.html"></div
</div>
<div class="list-objects" ng-show="!editable">
<!-- ... -->
</div
The default value of editable is false, but when I switch to true the include directive doesn't work.
Note: I'm using Angular-1.0.7
I'm not able to recreate this issue. Take a look at this plunker that loads two different templates. (The both look odd, since they're templates stolen from other plunkers to allow for xss).
Maybe this issue is caused by the two incomplete div ending tags, that are .

Creating complex static Markup with ember.js

I am trying to render my application template, which is getting very complicated, so I want to split it up into separate <script type="text/x-handlebars">'s
I think I want to use the {{view}} helper, but I don't know. Let's say I have this:
<script type="text/x-handlebars" data-template-name="application">
<div id="wrapper" class="clearfix">
<hgroup>
<header>
<div class="logo"></div>
<h1 id="facilityName">{{facilityName}}</h1>
<div id="sessionInfo">
<a id="userName">{{user}}</a>
<a id="logOut" href="../logout">log out</a>
</div>
</header>
</hgroup>
{{view App.breadcrumbsView}}
</div>
</script>
And I want to load this next template inside of the one above:
<script type="text/x-handlebars" id="breadcrumbs">
<div id="breadcrumbs">
<p>
Network
{{#each breadcrumbObj}}
<span>></span><a {{bindAttr href="link"}}>{{name}}</a>
{{/each}}
</p>
</div>
</script>
Right now I am trying to do this with this code from my app.js
App.breadcrumbsView = Ember.View.create({
templateName: 'breadcrumbs',
breadcrumbObj: Util.breadcrumbs()
});
This is not working and I am getting Uncaught Error: assertion failed: Unable to find view at path 'App.breadcrumbsView'
Thanks
I think that you declared your App using var keyword. So it's not visible in handlebars template.
Change this
var App = Ember.Application.create();
To this
App = Ember.Application.create();
And you have to use extend instead of create when creating your views. Because ember will handle the object lifecycle like: create, destroy, add and remove binding etc.
#Marcio is right, you should .extend() and let the framework create it for you automatically by request. Furthermore when you extend the best practice is to use capitalized names like App.BreadcrumbsView.
See here a demo how it renders correctly doing it this way.
Hope it helps.
