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) ;
}

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>
Check example below. In this case the 'expensiveFunction' is called for every item in myList
<ul>
<li ng-show="expensiveFunction(period)" ng-repeat="a in myList">
<a ng-click="onMove(period)">Move here </a>
</li>
<li ng-hide="!canBook">
<small>No free resources</small>
</li>
</ul>
Any ideas on how to prevent that?
<ul>
<!-- Possible, but creates invalid html -->
<div ng-show="expensiveFunction(period)">
<li ng-repeat="a in myList">
<a ng-click="onMove(period)">Move here </a>
</li>
</div>
<li ng-hide="!canBook">
<small>No free resources</small>
</li>
</ul>
Thanks for any suggestion

If the value of period is static or at least does not change with every iteration I would calculate the expensiveFunction(period) only once when the corresponding controller is loaded:
$scope.period = whatEverItIs
$scope.isExpensive = expensiveFunction(period);
And in your view:
<ul>
<li ng-show="isExpensive" ng-repeat="a in myList">
<a ng-click="onMove(period)">Move here </a>
</li>
<li ng-hide="!canBook">
<small>No free resources</small>
</li>
</ul>
You can try to make all calculations in a separate function by adding new display attribute to store statuses for ng-show.
Try to make all your calculations at once by calling function once.
For example.
/**
* Expensive function
* #param {string} lists
* #returns {object}
*/
function expensiveFunction(lists){
angular.forEach(lists, function (key, value) {
lists.display = true; // here goes your logic
});
return lists;
}
var myList = expensiveFunction(myList);
<ul>
<li ng-show="a.dispaly" ng-repeat="a in myList">
<a ng-click="onMove(period)">Move here </a>
</li>
<li ng-hide="!canBook">
<small>No free resources</small>
</li>
</ul>
I want to loop li with different condition and apply different html depending on that condition.
If i code this way
<ul ng-repeat="item in items">
<li ng-if="item == '1'">
<div><span> <span>My test 123</span>
{{item }}
</span></div>
</li>
<li ng-if="item == '2'">
<div><span class="xyz"> <span class="abc">My new test XXX</span>
{{item }}
</span>
<span>123</span>
</div>
</li>
</ul>
It repeat as
<ul ng-repeat="item in items">
<li>My test 123
1</li>
</ul>
<ul ng-repeat="item in items">
<li>
My new test XXX
2 123</li>
</ul>
But i want
<ul ng-repeat="item in items">
<li>My test 123
1</li>
<li>
My new test XXX
2 123</li>
</ul>
Any solution?
Thanks.
Repeat on the DOM element you want repeated?
<ul>
<li ng-repeat="item in items">{{item }}</li>
</ul>
<ul >
<li ng-repeat="item in items">{{item }}</li>
</ul>
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:
$scope.rows = [row1, row2];
In your template:
<ul ng-repeat="row in rows">
<li ng-repeat="person in row">
<img data-ng-src="img/{{person.code}}.jpg">
<h3>{{person.name}}</h3>
<p>{{person.description}}</p>
</li>
</ul>
I am using angularjs to render a hierarchical structure. The test case is at http://jsbin.com/agodoj/1/edit
My question is why ng-repeat stop working at level 3 ? Thanks
Here is my model
function Test($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>
