I've got this template:
<div class="container-fluid">
<div class="row">
<div class="col-xs-12" ng-repeat="product in ad.products">
<a href="{{product.link}}">
<h1>{{product.title}}</h1>
<img src="{{product.src}}">
<p>{{product.description}}</p>
<h5>{{product.price}}</h5>
</a>
</div>
</div>
</div>
From my controller I need to evaluate this template so that it checks how many products that have been selected and then it interpolates each product's values into the template. After that is done I also need to remove the ng-repeat so it doesn't fire an error in the external pages that will use this where angular is not present. However I'd figure that I'd just use a regex to look up the ng-repeat and everything in the expression and then remove it.
I've been looking at $interpolate and $compile but I can't figure out how to work with them from my controller so that it does what I want. This is because when I use these on my template and then console log the template value it's a function with a whole lot of nonsense in it.
So doing this:
ad.html = $compile(res.data, $scope);
Generates something like this:
function(b,c,d){rb(b,"scope");e&&e.needsNewScope&&(b=b.$parent.$new());d=d||{};var h=d.parentBoundTranscludeFn,k=d.transcludeControllers;d=d.futureParentElement;h&&h.$$boundTransclude&&(h=h.$$boundTr…
Can someone shed some light on how to achieve what I want?
Your are using $compile function in wrong way, you should call $compile(html) function by passing $scope parameter like below.
var compiledDOM = $compile(res.data)($scope);//then do append this DOM to wherever you want
ad.html = compiledDOM.html(); //but this HTML would not make angular binding working.

I am using bootbox, I need display product information in it. The product information is returned as json with rest call. I am thinking using a template, and transform from the json to html. I need ng-repeat etc, in the template. The idea way is I can call template and get a html result.
But it seems angularjs $compile need bind to element to render. any idea?
I think you can use ng-include:
var app = angular.module('myApp', []);
app.controller('productCtrl', function($scope) {
$scope.productInfos = [];
});
Use ng-include (You have to the adjust the path depending the location of your template)
<div ng-app="myApp" ng-controller="productCtrl">
<div ng-include="'product-information.html'"></div>
</div>
You can do ng-repeat in product-information.html:
<div ng-repeat= "info in productInfos"> {{ info.prop1 }}</div>
I'm trying to do a very simple thing. I'm displaying a list of values with Edit links beside them. Clicking the edit link reveals a form that lets you update the value.
(I've simplified the question so the items just have one field "name". My actual use case has more fields, but is canonically equivalent.)
I've run into something that looks like a bug in Angular, but given my limited experience with it, I'm not so sure. Here's how I'm trying to do it:
<div ng-repeat-start="item in items" ng-controller="ItemCtrl as ctrl" ng-hide="ctrl.isEditing">
<span>Name: {{item.name}}.</span>
<a href='#' ng-click='ctrl.startEditing()'>Edit</a>
</div>
<div ng-repeat-end ng-show="ctrl.isEditing">
<input type='text' ng-model='item.name'/>
<a href='#' ng-click='ctrl.save()'>Save</a>
</div>
My controller looks like this:
app.controller('ItemController', function() {
this.isEditing = false;
this.startEditing = function() { this.isEditing = true; }
this.save = function() { this.isEditing = false; }
});
Clicking on Edit link calls the right controller function, and the first div hides. But the second div does not hide.
When I rearrange the code to look like this (essentially wrapping the two divs with a wrapper element), all is well.
<div ng-repeat="item in items" ng-controller="ItemCtrl as ctrl">
<div ng-hide="ctrl.isEditing">
<span>Name: {{item.name}}.</span>
<a href='#' ng-click='ctrl.startEditing()'>Edit</a>
</div>
<div ng-show="ctrl.isEditing">
<input type='text' ng-model='item.name'/>
<a href='#' ng-click='ctrl.save()'>Save</a>
</div>
</div>
Any idea what is technically wrong with the first version? Note that the <input> boxes do get populated with the right values from item.name.
PS: There's a reason why I'm trying to keep the two divs siblings: in my use case, they are actually implemented as two trs which are supposed to appear right below each other in a table.
It's not a bug from angular but it is quite logical.
<div ng-repeat-start="item in items" ng-controller="ItemCtrl as ctrl" ng-hide="ctrl.isEditing">
<span>Name: {{item.name}}.</span>
<a href='#' ng-click='ctrl.startEditing()'>Edit</a>
</div>
<div ng-repeat-end ng-show="ctrl.isEditing">
<input type='text' ng-model='item.name'/>
<a href='#' ng-click='ctrl.save()'>Save</a>
</div>
If you see the above code you have injected controller only to the first div so obviously sibling div doesn't know what is ctrl or ItemCtrl until and unless you do as in you second way.
So if you want to achieve it as sibling, if you are using routing then add the controller attribute in your route path.
So that the controller will be active for that entire template and you can achieve what you want.
Hope it helps.
Thats because controller has its own scope. When you placed controller ONLY on your first div controllers' scope is limited to only this one div. When you wrapped both your divs inside another and place controller on wrapper, controllers' scope now is all that inside this wrapper. So in this case this works fine and this is not the angular bug
I have a <ul> that gets populated with the server. But in that controller there is also an iframe. When the <li>'s arrive there is some disconnect between them and the iframe even though they are in the same controller.
When you click one of the li's it should change the class on the iframe but it's not. However, If I move the iframe inside of the ng-repeat that injects the iframe it works.
View
<div class="content" ng-controller="FeedListCtrl">
<ul>
<li ng-repeat="item in items">
<div data-link="{{item.link}}" ng-click="articleShowHide='fade-in'">
<div ng-bind-html="item.title" style="font-weight:bold;"></div>
<div ng-bind-html="item.description"></div>
<!-- it works if i put the iframe here -->
</div>
</li>
</ul>
<!-- doesn't work when the iframe is here -->
<iframe id="article" ng-class="articleShowHide" src=""></iframe>
</div>
Here is the controller. It does an ajax call to get the data for each <li>
Controller
readerApp.controller('FeedListCtrl', ["$scope", "$http", "FeedListUpdate", function ($scope, $http, FeedListUpdate) {
$scope.setFeed = function (url) {
$http.get('feed?id=' + FeedListUpdate.GetCurrentFeedUrl()).success(function (data) {
$scope.items = data.currentFeed.items;
});
};
}]);
When inside of an ng-repeat you are in a different scope which means you are not setting the variable you think you are. Use $parent and that should work. The syntax is:
<div data-link="{{item.link}}" ng-click="$parent.articleShowHide='fade-in'">
Side note for others finding this - sometimes adding curly brackets helps as well. For more information on ng-class see here: http://docs.angularjs.org/api/ng/directive/ngClass
An Example
In case anyone wants to see this in action, I put together an example demonstrating a few ways to set the class as well as demonstrating the issue in scope (See: http://plnkr.co/edit/8gyZGzESWyi2aCL4mC9A?p=preview). It isn't very pretty but it should be pretty clear what is going on. By the way, the reason that methods work in this example is that the scope doesn't automatically redefine them the way it does variables so it is calling the method in the root scope rather than setting a variable in the repeater scope.
Best of luck!
I have a site that links to a component through ng-include:
<div id="tracklist">
<ng-include src="'partials/tracks.html'">
</ng-include>
</div>
the partial looks like this:
<div ng-controller="TracklistController">
<div ng-repeat="track in tracks">
<a ng-click="$('body').css('background-color', 'red')" href="#/tracks/{{ track.id }}" class="track-link" data-audio-source="{{ track.source }}">{{ track.trackNumber + " - " + track.title }}</a>
</div>
</div>
It renders fine and works, but my ng-click event does not fire for some reason. Note that changing the body background color is just an obvious test to see if it's failing. I've tried it with my actual function (declared globally when the document loads for now), and I've also tested with console.log. None of it works, so clearly ng-click is just not working. Any ideas?
Make sure you put your function in the controller and assign it to the $scope.
<a ng-click="action();">
function TracklistController($scope){
$scope.action = function(){ ... }
}
ngClick doesn't accept arbitrary JavaScript or functions defined outside of Angular! ngClick accepts an AngularJS expression. For example, data-ng-click="foo()" will call foo on the current scope!
I recently started using jasmine-jquery (1.3.1) together with angular (1.0.6) and need an advice on testing GUI.
I have some view for controller, which has angular directives, like 'view.html':
<div id='main-div'>
<div my-directive objects-to-iterate='someScopeObjects'>
<span id='default-span'>some default text</span>
</div>
</div>
, and in JS a directive "myDirective" is defined, having template-by-url 'myDirective.html' which includes ng-repeat and makes some nested div (row) foreach in objectsToIterate.
I load fixtures for 'view.html' and 'myDirective.html'.
Now I would like to test that during user interaction there are really some elements (rows) in 'myDirective' repeated block.
Beginning was simple:
var div = $('div#main-div');
div = $compile(div)(scope);
scope.$digest();
expect(div).toBeVisible();
And now I'm stuck. Cannot get access to "generated" source of 'myDirective' element. If I use
div.find('whatever-selector-for-element-my-directive'),
I get
<div my-directive objects-to-iterate='someScopeObjects'>
<span id='default-span'>some default text</span>
</div>
If I try to compile+digest this html against scope, I still get same markup. How could I get "generated" source, looking like (pseudo)
<div id='my-directive-content'>
<div id='object-1'>blah</div>
<div id='object-2'>blah</div>
</div>
in order to check if there are N rows visible to user?
someScopeObjects in scope exist and are valid.
And my next step is actually testing same thing for directives nested inside of 'my-directive', so I somehow have to get access to the scope of 'my-directive'. How? :)
Thank you.
