From what I read, the most common cause of this problem is when the controller is included in the template and in the route provider. In my case, only the parent template containing this html is being included in the router, and has its own controller. The sub-templates are being included as a result of a menu selection
So, whenever the menu item is selected, the template gets loaded in, and everything in the controller executes twice. Can it be a product of the the ng-switch or ng-include?
<span ng-switch on="selection">
<div ng-switch-when="0">
<div ng-include="'partials/one.html'" ng-controller="oneController"></div>
</div>
<div ng-switch-when="1">
<div ng-include="'partials/two.html'" ng-controller="twoController"></div>
</div>
<div ng-switch-when="2">
<div ng-include="'partials/three.html'" ng-controller="threeController"></div>
</div>
</span>
Edit:
The included partials do not include the controller again. I've triple checked that these controllers are not mentioned anywhere other than this piece of code. The contents of the one/two/three partials look like this, and the controller still runs twice.
<div>Nothing to see here.</div>
I am making an educated guess here... but does your "'partials/one.html'" also have a ng-controller="oneController" in it? If so, you either need to remove the ng-controller declaration from your include div or from your partial.

Situation: I have a view where I'm including a fragment with ng-include. The fragment loads perfectly and works as expected when inside view where controller is defined.
My problem is, that when I want to include external component inside the "ng-include" fragment "myView.html", it doesn't show up. When including it inside the main view where the controller is, it shows up and works as expected.
Main view:
<div ng-controller="MyController">
<div data-ng-include src="'views/myView.html'"></div>
<!-- When loaded here, the component shows up -->
<!-- <div id="componentDiv"></div> -->
</div>
Fragment "myView.html":
<div>
<div id="componentDiv"></div>
</div>
The component is loaded inside the "MyController", where "componentDiv" is the "id" of "div" where the component is placed:
var testObj = new TestObj({"container": "componentDiv"});
Trying to do this to be able to use this fragment with full functionality in several places.
Any ideas or suggestions what to look up or try?
IMHO I think that by saying "...to be able to use this fragment with full functionality in several places" you just answered your question. What you need is to build a custom directive and use it in any place you like.
see directive samples e.g. Angular documentation on directives
:) I have a input in the body of my index.html file Which acts like a static header to my templates. The only problem is that i have the filter in my template like so:
<!-- Home Template -->
<script id="home.html" type="text/ng-template">
<ion-view title="plz help">
<ion-content>
<div class="list" id="list" ng-repeat="phone in phones | filter:query">
...
</div>
</ion-content>
</ion-view>
</script>
So that makes it "2 separate files" (they are both inside index.html). This makes it so that i can't for example "clear the filter" from a button in my header that's outside of the template.
Is there any way I can "include" the different "files" in each other so that i can execute JavaScript in in both "files"?
Thanks in advance!
You can do this with a nested scope. Because query live in root scope, is visible from scope of your controller. You have exemple here
But, sometimes there is a problem that variable from root or parent scope is not visible in nested scope if previously is not defined in main controller. Also, you can use $rootScope service to easier access.
Hope to I clarified a little.
I have the following code:
<div ng-repeat="item in items">
<div ng-include src="itemG.html"></div>
</div>
then in itemG.html I have:
<img src="{{item.image}}">
How can I get my ng-repeat to print out all of the images?
There are 2 potential problems in the code...
src="itemG.html" needs an extra pair of single quotes like this:
<div ng-repeat="item in items">
<div ng-include="'itemG.html'"></div>
</div>
And the img tag is missing a closing ":
<img ng-src="{{item.image}}">
Plunker: http://plnkr.co/edit/7IUs7WPdUYkfVVKtBN1m?p=preview
Basically, what this comes down to is that the browser will interpret what inside the src attribute literally, until angular comes along to replace it. If you have a string constant, you can use single quotes inside the src="'myurl.html'", but if you have a value that needs to be bound by angular, you have to use ng-src and the expression syntax of {{ }}
You also need to bind a model to your template file itself. It's not going to pick up the bindings from your repeater without some help from either the ng-include event directives, or it's own model/controller/directive. There are too many different ways to demonstrate that, and it's also relevant on what markup is in your template file, which I can't say.
However, if the img tag is the only thing in that file, then instead of the file, I'd just do this:
<div ng-repeat="item in items">
<img ng-src="item.image" />
</div>
Since you're inside a repeat, it's already being included, making the ng-include redundant.
In principal code
<div ng-repeat="item in items">
<ng-include src="itemG.html" ng-controller="MyCtrl" ng-init="i=item"><ng-include>
</div>
then in itemG.html I have:
<img src="{{i.image}}">
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 .
Hey all I'm trying to get a feel for angular and have ran into a little snag.
I have a container structure like the following:
<div class="main-container" ng-view>
<!-- The below divs are constantly being
reloaded based on the current URL and it's associated view -->
<div class="left-col">
</div>
<div class="right-col">
</div>
</div>
Before I implemented Angular I just had a simple script that would check the height of the window and set the height of the left column and right column divs accordingly.
With angular there is probably a better way to do this then attaching an event function to the window object. Basically I want to fire a function everytime a new view is rendered but not duplicate the below code in all of my angular controllers like so:
$scope.$on('$viewContentLoaded', setColumnHeight);
Any help would be appreciated. Thanks!
I've solved this problem in my app by having a root "Application Controller" at the top of the DOM tree. For example:
<body ng-controller='applicationController'>
...
<div class="ng-view"></div>
...
</body>
applicationController is always there, and can set up bindings on its scope when it is created.
How about putting that event listener on the root scope:
$rootScope.$on('$viewContentLoaded', setColumnHeight);
You could use something like this:
<div class="main-container" ng-view>
{{ setColumnHeight() }}
<!-- The below divs are constantly being
reloaded based on the current URL and it's associated view -->
<div class="left-col">
</div>
<div class="right-col">
</div>
</div>
and it will check the height every time a render is made, however, this seems to be a bit over processing.
The best approach would be to only update the height from both columns when the height of one of them changes. For that you could use DOM Mutation Observers, however they are not yet available on all browsers. If that's not a problem for you, check the mutation-summary lib.
If you are using jQuery you can also try this: https://github.com/jqui-dot-net/jQuery-mutate (examples here).
