I am currently trying to add links in my view. I do have links which basically contains html tags as strings.
I tried:
<p data-ng-repeat='i in links' >{$ i.link $}</p>
which basically just deploy in my view : mylink
So I did try:
<p data-ng-repeat='i in links' ><span data-ng-bind-html="i.link"></span></p>
It doesn't work though, any idea how could I achieve this ?
Thanks.
Add the $sce as a dependancy of the module
angular.module('myApp', ['$sce']);
When getting the links
angular.forEach($scope.links, function(value){
value.link = $sce.trustAsHtml(value.link);
});
Using Safe Contextual Escaping (docs.angularjs.org/api/ng/service/$sce) and using trustAs delegate you're telling Angular that this value is safe to use within that context. In this example. $sce.trustAsHtml returns an object that angular can trust is safe to as HTML.
In the first case, you'll actually want to use:
<p data-ng-repeat='i in links' >{{ i.link }}</p>
Double braces, not brace-dollar. In the second case, ng-bind-html will require that you have added "ngSanitize" to your module's dependency list.
angular.module('yourAppNameHere', ['ngSanitize'])
Edit:
If you really do want clickable links on the page, then do pretty much what #sreeramu suggested (Though I'd see if you can't find a way to add a nice description):
<p data-ng-repeat='i in links' ><a ng-href="{{i.link}}">{{i.desc}}</a></p>
(Notice that he suggested using ng-href, instead of href. He's right.)
Insert ngSanitize as a dependency to you app:
angular.module('myApp', ['ngSanitize'])
But before be ensure that you are including the script angular-sanitize.js.
Good luck!
It might be that your links have already got the a tags with it so in this case you do not need to re-add the a tags...
In this case do this...
Add this to you scripts (include acc. to your angular version)
<script type="text/javascript"
src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.5/angular-
sanitize.min.js"></script>
Add this to your app.js
var app = angular.module('modulename', [ 'ngSanitize']);
And than in your view do this
If it is the div that you want the link to attach to...
<div ng-bind-html="i.link"></div>
The above would give you something as this
<div><a href='your link'></a></div>

If I put this:
<button type="button" class="btn btn-info" data-toggle="tooltip" data-placement="top" title="Tooltip on top">
Tooltip on top
</button>
Inside the index.html file, just between the <body> tags, it works -
I got the tooltip shown as it should be.
But If i put the same thing in a directive of ng-view - like this:
<div ng-view></div>
The button is shown but the tooltip is not get fired.
The ng-view contains another html template file, using the ngRoute module which contains the <button> tag as specified above.
It seems like jQuery cannot select elements that are located inside the AngularJS ng-view directive.
How could this be solved?
jQuery can and does select the button. However, AngularJS's digest loop is likely removing the tooltip content from the DOM. Outside of the element that hosts the AngularJS application, this does not apply (no pun intended). Furthermore tooltips popovers are added asynchronously.
To make AngularJS recognize the change
import $ from 'jquery';
import 'bootstrap';
import angular from 'angular';
run.$inject = ["$scope"];
function run($scope) {
const tooltippedElements = $('[data-toggle="tooltip"]');
tooltippedElements.on('hidden.bs.tooltip', onShownOrHidden);
tooltippedElements.on('shown.bs.tooltip', onShownOrHidden);
function onShownOrHidden() {
if (!$scope.$phase()) {
$scope.$apply();
}
}
}
angular
.module('app', [])
.run(run);
But instead of going through all of thirs trouble, use
angular-ui-bootstrap or something similar.
I have found the answer:
jQuery selectors, like $('[data-toggle="tooltip"]').tooltip(); are getting actioned before ng-view is getting actioned.
Therefore tooltip selector is trying to select an element which is not already been loaded to the DOM.
The solution for this problem, is simple:
Include jQuery before AngularJS scripts in the index.html file (at the end of the body tag).
Add ng-if directive to each jQuery script that has selectors (but not to the main jQuery file), like this:
<script src="assets/js/scripts.rtl.js" ng-if="initSrc"></script>
Set $rootScope.initSrc=true after any directive/component is loaded.
All of the jQuery functions will be working properly.
I have a a single span element in my page. I am concatenating words to a single variable in AngularJS and then referencing the variable to the span element in the page.
$scope.abc = "Downstream";
$scope.abc.concat('<b>','Upstream',</b>);
When the page is viewed, it displays Downstream<b>Upstream</b>
How to display the word Upstream alone in Bold?
according to this https://docs.angularjs.org/api/ng/directive/ngBindHtml
You need to include the ngBindHtml and $sanitize service
In your js file, it should be
angular.module('App', ['ngSanitize'])
.controller('Ctr', ['$scope', function($scope) {
$scope.abc = "Downstream";
$scope.abc2 = $scope.abc.concat('<b>','Upstream','</b>');
}]);
In your html file, it should be
<div ng-controller="Ctr">
<p ng-bind-html="abc2"></p>
</div>
Seems a duplicate to angular variable generating html.
I don't know angular, but reading that post it's easy. Just do:
$scope.abc = $scope.trustAsHtml($scope.abc);
HTML
<div data-ng-bind-html="abc "></div>
Also check your Angular version, for version 1.2 or lower you could use the ng-bind-html-unsafe binding.
<div class="post-content" ng-bind-html-unsafe="abc"></div>
This does not work anymore at Angular 1.2+ According to comment of TheSharpieOne:
"It has been replaced with Strict Contextual Escaping. See docs.angularjs.org/api/ng.$sce"
I'm new to AngularJS and I'm struggling with the following issue.
I need to implement a 3 step workflow as follows:
Make a call to a web service that returns a list of strings. For example, ["apple", "banana", "orange"], etc. I intercept the response and add the angle brackets around each of these strings before I send it to the Views.
For each of the string returned by the service, I have to render
<apple />
<banana />
<orange />
Finally, get the actual AngularJS directive corresponding to each of those strings to "execute" (not sure what the right word is) and replace the elements above with the content from the templateUrl property as mentioned in each of their respective directives.
Right now, I'm doing Step 1 and Step 2 above using AngularJS. But I understand that they can be done using plain JavaScript using AJAX calls.
My problem is that the directives don't get "run" or "executed" and I have these tags displayed as plain text on the page -
<apple />
<banana />
<orange />
etc.
How do I tell Angular to replace the custom tags with the actual content from their templates?
Thanks for your help.
UPDATE: Here's what the code looks like:
<div class="content" ng-controller="mainController">
<ul class="feeds">
<li ng-repeat="fruit in fruits">
<div ng-controller="fruitSpecificController"> {{fruit}} </div> <!-- This renders <apple />, <banana />, etc. -->
</li>
</ul>
</div>
Also note that each fruit can have its own controller. In the code above, I say "fruitSpecificController", but ideally that would also be generated at runtime. For example, "appleController", "orangeController", etc. and yes, they'll be child controllers of the parent "mainController".
You can use the compile method, but there is a built in directive that will do this for you - if you are willing to load in via a URL.
ng-include
Using ng-include="'/path/to/template.html'" - the evaluated expression URL will be requested and added to the DOM as a child (compiled for you).
You can also cache the templates using $templateCache (if you want to request multiple templates at the same time or cache it for multiple includes).
That would look something like this:
$templateCache.put(/path/to/template.html, 'apple html string');
custom directive (with $compile)
Otherwise, if you want to load in and compile a string - use a directive inside of a ng-repeat.
.directive('unsafeHtmlCompile', function($compile){
return {
link: function(scope, element, attrs){
scope.$watch(attrs.unsafeHtmlCompile, function(val){
if(val !== undefined){
element.html('');
var el = angular.element(val);
element.append(html);
$compile(el)(scope);
}
});
}
}
}
Remember to remove the watcher, if your data won't change :-)
You probably just need to use the $compile service. The docs aren't super helpful but the gist is that you call $compile, passing in the DOM element (in your case the parent of your directives). That returns a function that you then execute, passing in the scope that you want to use ($rootscope is probably safe).
$compile(element)($rootScope);
I am trying to render some unsafe HTML (basically a HTML snippet with some inline styling) and have the following code in my view:
<div ng-repeat="snippet in snippets">
<div ng-bind-html="snippet.content"></div>
</div>
All my styling gets removed...
I've heard of people using ngBindHtmlUnsafe however I couldn't find a reference to it and simply putting ng-bind-html-unsafe doesn't render anything.
Any help would be appreciated.
The ng-bind-html-escape was removed in AngularJs 1.2.
To achieve the same effect I would advise you to create a filter to trust the resource (you should include the $sce module ):
app.filter('unsafe', function($sce) {
return function(val) {
return $sce.trustAsHtml(val);
}; });
Usage:
<ELEMENT ng-bind-html="htmlValue | unsafe"></ELEMENT>
You shouldn't forget to include the ngSanitize as the app dependency:
angular.module('app', ['ngSanitize'])
Cheers.
You can bypass it using $sce.trustAsHtml . See documentation
self.snippet.content = $sce.trustAsHtml('some html');
I am a super beginner to EE and was literally thrust into managing my company's website that is built in EE without training. I'm not a programmer, I'm a designer, so it's been taking me awhile to plug through this. So I might need some dumbed down language :)
I want to create a page that has some Javascript on it. Do I need to create a new template JUST so I can put some javascript on it? And how do I communicate to EE that I want the page I created to go with that template?

At glance I can see a couple things that might be confounding you...
You started with a template called 'index' in the 'page' template group.
Looks like the 'page' template you are starting from is meant to display a single entry from the 'page' weblog.
So a request url might look something like this:
http://example.com/page/some_url_title
where 'some_url_title' is the 'url_title' value one of the entries in your 'page' weblog.
Now you have gone and duplicated the index template and called this new template 'clinician-map'.
So you would call an entry through this template at:
http://example.com/page/clinician-map/some_url_title
Now, notice that the first url had 2 segments, while the second had 3 segments?
That's not normally a big deal but the fellow who designed the index template did something that makes it problematic. He is taking the value of segment_2 and passing it through an embed.
So in the first example (index) we are passing the dynamic value "some_url_tile" while in the second example (clinician-map) we are passing "clinician-map". If the embedded template 'html_head' is expecting to get a valid url_title but instead gets the string 'clinician-map' you are likely going to get unexpected results.
Also I don't think we know enough about what you are trying to do to decide if creating a new template is the right approach here. It may be that what you actually need is a new weblog entry or perhaps just a dynamic value inside your existing template.
If it did turn out that a new template is the best approach you could fix the problem I have described by simply replacing segment_2 with segment_3, but I am by no means certain that that is the way you want to go.
I want to create a page that has some Javascript on it. Do I need to
create a new template JUST so I can put some javascript on it?
More specifics would be needed in order to give a solid recommendation but in almost every case, I recommend keeping JavaScript grouped together either in the <head></head> or ideally right before the closing </body> tag if you can get away with it.
Looking at your template code, it appears all the JavaScript is stored in the embeds/html_scripts page. I would add the JavaScript you need to that template. If you only want the JavaScript to appear for certain pages only, I would make use of a conditional (which I'll outline at the end of my answer).
And how do I communicate to EE that I want the page I created to go
with that template?
ExpressionEngine URLs (by default) are assembled as follows:
http://website.com/group/template/url_title
Therefore if you have a page with a url_title of "contact-us", and you wanted that page to use a template in site/pages, you could tell your page to use that template like so:
http://website.com/site/pages/contact-us
That url is obviously fine and dandy for blog articles and such, but it's not that pretty; so ExpressionEngine also enables you to construct "page" based navigation which creates navigation tree based url structures, such as:
http://website.com/contact-us
There are a few third party modules that make it easy to build page navigation such as:
devot-ee.com/add-ons/structure
Using Structure, you specify the default template for each channel and can override the template for each page as well.
I duplicated the page/index template and renamed it to clinician-map
(the same name of the page I created in the publisher). EE didn't like
that and the page subsequently broke. All I want to do is insert one
javascript item, this seems way too inefficient for just one page.
Help??
(using EE 1.6.8) Here is my code from clinician-map template.
There are a number of things I would do different in regards to the template code you provided; however, as a quick fix here's how I would add the one line of JavaScript,
1) Open the embeds/html_scripts template and add the following logic:
{if segment_2 == "my_page_url_title"}
<!-- javascript here -->
{/if}
Note: Here's how segments are determined:
http://website.com/segment_1/segment_2/segment_3
Okay. I ended up just creating a new webblog and new template group and finally it seems like it's working. My javascript is not, but I can figure that out.
Thank you so much for your patience with helping me!
