I would think this is fairly straight forward, but if I try to include a bound {{data}} model as a parameter in ng-click, nothing happens (an no error is fired in Console).
For example, I have the following:
<p ng-repeat='item in array'>
<a ng-click='function({{item}})'></a>
</p>
Here is a plunker that is more fleshed out: plunker
If I click on the link, nothing happens. Ideas?
Found my own answer:
within ng-click, there is no need for the {{notation}}. It knows that "item" is an angular data model. Again, not super clear in the Angular documentation.
Here is the updated plunker that shows it working and not working.

I have a form and I want to check if all the fields are valid or not.
Currently I am using four different methods. Nothing is working. Here is my plunker:
http://plnkr.co/edit/c4czI1W1fvXR4881SP1z?p=preview
Here are the methods I am using to check for validity
<button ng-click="my.$valid && validityCheck()">Update</button>
<div>myForm.$valid = {{myForm.$valid}}</div>
<span ng-show="myForm.$valid" style="color:green">Yippii!</span>
<span ng-show="myForm.$invalid" style="color:red">Not :(</span>
Plunkder code has few errors.

ng-click should refer to myForm instead of my. ng-click="myForm.$valid

I am trying to understand how angular 1 digest cycles work and how they impact the existing scope. I have 2 controllers one of them is using angular material with a repeater. The second controller is a simple button click event. Both events print to the console to see what is happening.
What i am seeing is that every time i click the button on the second controller the repeater re-runs its entire calculation?
Is this how angular is intended to work? Please see attached the following codepen - when the button is clicked the repeater re-runs on the first controller every single time. I assume this is going to happen every single time any operations occurs on any controller - which just seems like madness.
the repeater code is as follows:
<div flex="50" ng-repeat="item in items">
<md-checkbox ng-checked="exists(item, selected)" ng-click="toggle(item, selected)">
{{ item }} <span ng-if="exists(item, selected)">selected</span>
</md-checkbox>
</div>
At first i thought there was something wrong in my angular but it seems like this happens anywhere full codepen bellow.
Codepen Example
If you don't want ng-repeat to rerun on change then use "track by $index" in ng-repeat
yes this is exactly how it is supposed to work. That is the nature of two-way binding, you constantly check whether one of both values changed.
If you want to turn off that feature and use a one-time binding you can use the :: syntax.
see in the documentation: https://docs.angularjs.org/guide/expression (you need to scroll down to One-time binding. Sadly there are no anchors :D)
I am new in angular. I click a button using ng-click. I send it paramter. Every is ok.
<div class="item item-text-wrap" ng-click="GetRecordPDF({{item.RecordId}})"></div
After this, I need change view and this view's controller will make a service call using "item.RecordId" parameter.
I hope I will explain what I want to do. Maybe, I make a wrong thing about call ing methods in angular.
How can I make this? Thanks in advance.
You no longer need the brackets '{{}}' for variables. You can read more over expressions on this site: https://docs.angularjs.org/guide/expression
Write this now:
<div class="item item-text-wrap" ng-click="GetRecordPDF(item.RecordId)"></div>
I'm using twitter bootstrap with a popover and got a AngularJS scoped variable to appear correctly. The below works.
(data-content="{{notifications[0].user}} shared {{notifications[0].user_two}}'s records")
When I add the following
(data-content="<b>{{notifications[0].user}} shared {{notifications[0].user_two}}'s records</b>")
No errors show up, but all of the {{}} no longer render.
So I tried this as a test of sorts
(data-content="<div ng-repeat='item in notifications'>test {{item}} <br/><hr/></div>")
Much like the last example, I see the "test" but not the {{item}}. And the "test" only show s up once, even though the notifications had three elements. When I look at the DOM there's this
<div class="popover-content">
<div ng-repeat="item in notifications">you <br><hr></div>
</div>
I've also tried just creating a directive to iterate through the array and make the output I want, but my attempt to set data-content equal to a directive have been failures. The examples I've found elsewhere I'm confident would work, but I just wanted to confirm before I begin implementing something like this (http://tech.pro/tutorial/1360/bootstrap-popover-using-angularjs-compile-service) or (Html file as content in Bootstrap popover in AngularJS directive) that I'm not missing a straightforward fix to the problem I outlined above that would not require me creating a directive.

html might be breaking it, try marking it as trusted html using $sce
How do you use $sce.trustAsHtml(string) to replicate ng-bind-html-unsafe in Angular 1.2+
$scope.html = '<ul><li>render me please</li></ul>';
$scope.trustedHtml = $sce.trustAsHtml($scope.html);
<button ... data-content="trustedHtml" ...> </button>
I am trying to do what looks like a simple process: to display a list of items received from an HTTP request with animation.
First of all, here is my way of doing it ( I am open to any suggestions to do it in a better angular way ):
I define a scope variable state that I initialize to loading in my controller and that I change to loaded when I receive data from the HTTP request.
I initialize a scope variable items with the received data.
In my view, I use ng-switch for the states, and ng-repeat with the items.
I define an animation with css on ng-repeat.
Here is a plunkr ( with a $timeout instead of the request ).
I cannot understand why the animation does not work.
Any help will be appreciated. Thanks.
The reason it is happening is because your ng-when. The same thing happens with ng-if, but would work fine if you used ng-show.
The problem is that when your ng-when condition returns true, the ng-when first renders it's content in a detatched dom (so animations do not happen). This dom is then attached to the dom tree (this step is animated but you would have to put your animation class on the ng-when).
When using something like ng-show or ng-hide things work as expected because the dom is always attached (it is simply shown/hidden).
This might be considered either a bug or a limitation of ng-animate, you might want to post a github issue and see if the angular guys have any thoughts.
It seems to be a "feature" of angular that it won't add .ng-enter to repeat items inside ng-switch-when block. You can remove ng-switch-when="loaded" and it will work (You don't really need it as ng-repeat won't do anything if there is no items)
<div ng-switch="state">
<div ng-switch-when="loading">
<p>Please wait...</p>
</div>
<div >
<ul ng-repeat="item in items" class="animate-items">
<li>{{item}}</li>
</ul>
</div>
</div>
