why ng-repeat stop working at level 3 - angularjs

I am using angularjs to render a hierarchical structure. The test case is at http://jsbin.com/agodoj/1/edit
My question is why ng-repeat stop working at level 3 ? Thanks
Here is my model
function Test($scope) {
$scope.cars = {
chrylser: {
nameplates: [{
name: "np1",
trims: [
"tirm1", "trim2"
]
}]
}
};
}
Here is my template
<div ng-app ng-controller="Test">
<div ng-repeat="(key, value) in cars">
{{key}}
<ul>
<li ng-repeat="np in value.nameplates">{{np.name}}, {{np.trims}}</li>
<ul>
<li ng-repeat="trim in np.trims">
(ng-repeat stop working here) {{trim}}
</li>
</ul>
</ul>
</div>
</div>

Just need to move the closing </li> tag after your inner <ul>. You had the <li ng-repeat="np in value.nameplates"> immediately closing, ending the loop.
<div ng-app ng-controller="Test">
<div ng-repeat="(key, value) in cars">
{{key}}
<ul>
<li ng-repeat="np in value.nameplates">{{np.name}}, {{np.trims}}
<ul>
<li ng-repeat="trim in np.trims">
works! {{trim}}
</li>
</ul>
</li>
</ul>
</div>
</div>

Why does $parent.$index equals $index?

In AngularJS 1.6.3 it is basically possible to nest ng-repeat.
I have determined, that in two nested ng-repeat the $parent.$index equals $index.
The following code is given:
<div ng-repeat="category in :: $ctrl.categories">
<span id="category-{{ $index }}">
{{ :: category.name }}
</span>
<ul>
<li ng-repeat="data in :: category.links"
id="link-{{ $parent.$index }}-{{ $index }}">
{{ :: data.name }}
</li>
</ul>
</div>
Expected resulting ID's for LI:
<div>
<span id="category-0">CatA</span>
<ul>
<li id="link-0-0">[..]</li>
<li id="link-0-1">[..]</li>
<li id="link-0-2">[..]</li>
</ul>
</div>
<div>
<span id="category-1">CatB</span>
<ul>
<li id="link-1-0">[..]</li>
<li id="link-1-1">[..]</li>
</ul>
</div>
Actual resulting ID's for LI:
<div>
<span id="category-0">CatA</span>
<ul>
<li id="link-0-0">[..]</li>
<li id="link-1-1">[..]</li>
<li id="link-2-2">[..]</li>
</ul>
</div>
<div>
<span id="category-1">CatB</span>
<ul>
<li id="link-0-0">[..]</li>
<li id="link-1-1">[..]</li>
</ul>
</div>
Can someone confirm this behaviour? Or did I miss something?
Working as expected.
angular.module('test', []).controller('Test', Test);
function Test($scope) {
var $ctrl = this;
$ctrl.categories = [
{
name: 'cat1',
links: [{name: 'l1'}, {name: 'l2'}, {name: 'l3'}]
},
{
name: 'cat2',
links: [{name: 'l4'}, {name: 'l5'}]
}
]
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.3/angular.min.js"></script>
<div ng-app='test' ng-controller='Test as $ctrl'>
<div ng-repeat="category in :: $ctrl.categories">
<span id="category-{{ $index }}">
{{ :: category.name }}
</span>
<ul>
<li ng-repeat="data in :: category.links"
id="link-{{ $parent.$index }}-{{ $index }}">
{{ :: data.name }}
</li>
</ul>
</div>
</div>
You probably have some scope generating elements surrounding your child layer e.g. ng-if, ng-repeat, ng-switch. In this case you'll need to add more layers of $parent

ngRepeat Add to the current index

I have the following code, I want to add 1 to the current index of the second Name, because if I don't, it will output the same name in a single line. How do I add to the current index of ngRepeat?
<ul id="speakerlist" ng-repeat="data in result">
<li>
<div class="col">
<h3>{{data.Name}}</h3>
</div >
<div class="col">
<h3>{{data.Name | $index+1}}</h3>
</div>
</li>
</ul>
I solved this by using jQuery, but I want to do it in angularjs way.
EDIT: additional info
var app=angular.module("myApp",[])
app.controller("myController",function($scope){
$scope.result=[{"Name":"Michael Jordan"},{"Name":"Kobe Bryant"},{"Name":"Kevin Durant"},{"Name":"Stephen Curry"} ];
});
The result I want Is:
Michael Jordan Kobe Bryant
Kevin Durant Stephen Curry
If I understand correctly, you want to display a li for every two items. You can do it something like this:
<ul id="speakerlist" ng-repeat="data in result">
<li ng-if="$even">
<div class="col">
<h3>{{result[$index].Name}}</h3>
</div >
<div class="col">
<h3>{{result[$index + 1].Name}}</h3>
</div>
</li>
</ul>
Of course you would also have to include some kind of check if the $index can reach the last one (if the collection has an un-even amount of items)
See this jsfiddle
You could even remove the double col html if you don't like duplicate html code:
<ul id="speakerlist" ng-repeat="data in result">
<li ng-if="$even">
<div class="col"
ng-repeat="item in [result[$index], result[$index + 1]]">
<h3>{{item.Name}}</h3>
</div >
</li>
</ul>
Try this code <h3>{{data.Name }} {{$index+1}}</h3> instead of your code
<h3>{{data.Name | $index+1}}</h3>
The result format looks like
Ramesh
Ramesh1
Rajendran
Rajendran1
I think you can make it simple this way.
var app=angular.module("myApp",[])
app.controller("myController",function($scope){
$scope.result=[{"Name":"hari"},{"Name":"ram"} ];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp" ng-controller="myController">
<ul id="speakerlist" ng-repeat="data in result track by $index">
<li>
<div class="col">
<h3 >{{data.Name}} {{data.Name+1 }}</h3>
</div >
</li>
</ul>
</body>
">
Why don't you do this ?
<ul id="speakerlist" >
<li ng-repeat="data in result">
<div class="col">
<h3>{{data.Name}}</h3>
</div >
</li>
</ul>
This way you don't need to change de $index, it will be automatic

AngularJS- how to change value of dynamic model

I want to change {{order.status}} to def when someone click updatestatus button.
<ul>
<li ng-repeat="order in orders">
<!--
<div ng-model="row[order.id]" >abc</div>
-->
<div ng-model="row[order.id]" >{{order.status}}</div>
updatestatus
</li>
</ul>
Controller
$scope.row = {};
$scope.changestatus = function(id) {
//console.log(id);
$scope.row[id] = 'def';
}
It does not work. Please help.
You don't need ng-model here. ng-model is used for inputs, textarea, select or custom form elements https://docs.angularjs.org/api/ng/directive/ngModel
<ul>
<li ng-repeat="order in orders">
<div>{{ row[order.id] }}</div>
updatestatus
</li>
</ul>
Here, you just need to update the view. For this ng-bind is used https://docs.angularjs.org/api/ng/directive/ngBind
<div> ng-bind="row[order.id]"></div> and <div>{{ row[order.id] }}</div> are similar
UPDATE
<ul>
<li ng-repeat="order in orders">
<div>{{ order.status }}</div>
Update Status
</li>
</ul>
Controller:
$scope.changestatus = function(order) {
//console.log(order.id);
order.status = 'the update status'; // status changed
}
Use {{row[order.id]}} instead of abc in your view and remove ng-model within your div.
<ul>
<li ng-repeat="order in orders">
<div>{{ row[order.id] }}</div>
updatestatus
</li>
</ul>
Or
<ul>
<li ng-repeat="order in orders">
<div ng-bind="row[order.id]"></div>
updatestatus
</li>
</ul>

ng-repeat syntax not correct

I have a parse syntax error when i try this :
<div ng-repeat="post in posts" id="{{post.idFB}}">
<p>{{post.name}}</p>
<ul>
<li ng-repeat="feed in feed{{post.idFB}}">
<p>{{feed.title}}</p>
</li>
<ul>
</div>
problem is the line <li ng-repeat="feed in feed{{post.idFB}}">, what is the good syntax ?
result expected is like feed846097918756247
The online app: http://www.monde-du-rat.fr/pmr/
EDIT : jmb.mage solution :
<ul ng-init="myFeed = myFeedFunction(raterie.idFB);">
<li ng-repeat="feed in myFeed | limitTo:1">adoptions are : {{feed.title}}</li>
<li ng-repeat="feed in feed846097918756247 | limitTo:1">search is : {{feed.title}}</li>
<ul>
only second li works, not the first with the automatically variable
I'd use only a feed object as follow, scope.feed[scope.posts[index].idFB]= 'whatever'
<div ng-repeat="post in posts" id="{{post.idFB}}">
<p>{{post.name}}</p>
<ul>
<li ng-repeat="feed in feed[post.idFB]">
<p>{{feed.title}}</p>
</li>
<ul>
</div>
If feed846097918756247 is a JavaScript object than you could do something like this
<div ng-repeat="post in posts" id="{{post.idFB}}">
<p>{{post.name}}</p>
<ul ng-init="var myFeed = eval('feed' + post.idFB);">
<li ng-repeat="feed in myFeed">
<p>{{feed.title}}</p>
</li>
<ul>
</div>
Although since it's using eval(), you may need to do the ng-init with a function like:
<ul ng-init="var myFeed = myFeedFunction(post.idFB);">
and then have a function in your controller:
function myFeedFunction(pId) {
return eval('feed' + pId) ;
}

How can I use the same piece of html with different data in AngularJS without duplication?

I need the following:
<ul>
<li data-ng-repeat="person in row1">
<img data-ng-src="img/{{person.code}}.jpg">
<h3>{{person.name}}</h3>
<p>{{person.description}}</p>
</li>
</ul>
<ul>
<li data-ng-repeat="person in row2">
<img data-ng-src="img/{{person.code}}.jpg">
<h3>{{person.name}}</h3>
<p>{{person.description}}</p>
</li>
</ul>
but I don't want to duplicate the html - I want to be able to pass in the two different arrays (row1 and row2) to ng-include or something similar. How can I do this in AngularJS?
You can give the array of rows to another model and use ng-repeat in ul tag
In your controller:
$scope.rows = [row1, row2];
In your template:
<ul ng-repeat="row in rows">
<li ng-repeat="person in row">
<img data-ng-src="img/{{person.code}}.jpg">
<h3>{{person.name}}</h3>
<p>{{person.description}}</p>
</li>
</ul>
