have this ng-repeat
<li class="tmmenu-admin-tabs-builder-panel-portlet" ng-repeat="question in questions">
<div>
<span class="tmmenu-admin-tabs-builder-panel-portlet-toggler" ng-click="tatbppTogler()">{{{tatbppt}}}</span>
<span class="tmmenu-admin-tabs-builder-panel-portlet-number">{{question.id}}</span>
{{question.text}}
</div>
<div class="tmmenu-admin-tabs-builder-panel-portlet-options" ng-show="showTatbppo">
...
</div>
</li>
I want, for click in "tmmenu-admin-tabs-builder-panel-portlet-toggler" change visibility "tmmenu-admin-tabs-builder-panel-portlet-options" and change text in "tmmenu-admin-tabs-builder-panel-portlet-toggler".
And i write this code for get result:
$scope.tatbppTogler = function(){
$scope.showTatbppo = !$scope.showTatbppo;
if($scope.showTatbppo){
$scope.tatbppt = "-";
}else{
$scope.tatbppt = "+";
}
}
It's works, but changed dom in all "Li", how changed only current (where user click) "li"?
You can do it like this:
<li class=portlet" ng-repeat="question in questions">
<div>
<span class="toggler" ng-click="showTatbppo=!showTatbppo">{{showTatbppo ? "+" : "-" }}</span>
<span class="number">{{question.id}}</span>
{{question.text}}
</div>
<div class="options" ng-show="showTatbppo">
...
</div>
</li>
Working fiddle, with this concept:
http://jsfiddle.net/x1nguaxj/
btw. You have very-very-very long css class names :)
1 way
you can pass this in ng-click="tatbppTogler(this)" and then in function manipulate with this
2 way
you can create custom directive and apply it to your li element and then on this directive bind click to element and listen , and on click function will be triggered your listener and you will have access on this element
You can create an attribute id for each question and then change based on the id of the question you clicked
I would suggest you'd take a look at $index. From the angularjs docs:
iterator offset of the repeated element (0..length-1)
Using this, you can clearly determine the certain div that was clicked on.

I have a list of items (divs) with a button. When I click on one of this buttons I can access the element using
$event.currentTarget
that returns some thing like
<div ng-click="myFunc()">
<i class="someclass"></i>
<span>bla bla</span>
</div>
how can I access and elements to modify attributes like class?
Don't. Use existing directives like ng-class or ng-if, etc in your html templates.
<div ng-click="clicked = true">
<span ng-class="{'someclass': clicked}">bla bla</span>
</div>
See stackblitz
Although you can get the html dom element and edit it you should only do this as a last option and other angularjs supported methods have failed or are not supported.
template
<div ng-click="myFunc($event)">
<i class="someclass"></i>
<span>bla bla</span>
</div>
controller
$scope.myFunc(event) {
var elem = angluar.element(event.currentTarget);
elem.children(".someclass").removeClass("someclass")
}
I am new to AngularJS.
I have created <li> to which I used ng-repeat.
<li> contains images and buttons like like, comment and share which is inside <li> and created by ng-repeat.
I have made function which will replace empty like button to filled like button (By changing background image of button).
But problem is this trigger applies to only first like button and other buttons does not change.
How can I fix this?
Code:
HTML:
<html>
<body>
<ul>
<li ng-repeat="media in images"><div class="imgsub">
<label class="usrlabel">Username</label>
<div class="imagedb">
<input type="hidden" value="{{media.id}}">
<img ng-src="{{ media.imgurl }}" alt="Your photos"/>
</div>
<!-- <br><hr width="50%"> -->
<div class="desc">
<p>{{media.alt}}</p>
<input type="button" class="likebutton" id="likeb" ng-click="like(media.id)" ng-dblclick="dislike(media .id)"/>
<input type="button" class="commentbutton"/>
<input type="button" class="sharebutton"/>
</div>
</div> <br>
</li><br><br><br>
</ul>
</body>
</html>
JS:
$scope.like = function(imgid)
{
document.
getElementById("likeb").
style.backgroundImage = "url(src/assets/like-filled.png)";
alert(imgid);
}
$scope.dislike = function(imgid)
{
document.
getElementById("likeb").
style.backgroundImage = "url(src/assets/like-empty.png)";
}
Thanks for help & suggestions :)
The id for each button should be unique but in your case, it's the same for all buttons ('likeb').
You can set the value of the attribute 'id' for each button dynamically by using '$index' and passing '$index' to the functions as follows:
<input type="button" class="likebutton" id="{{$index}}" ng-click="like($index)" ng-dblclick="dislike($index)"/>
Then in your controller, you can use the functions with the passed value.
For example,
$scope.like = function(index)
{
document.
getElementById(index).
style.backgroundImage = "url(src/assets/like-filled.png)";
}
Another good alternative in your case would be to use the directive ngClass.
use 2 css class for styling liked and disliked state, and then put the class conditionally with ng-class instead of DOM handling. and if you really want to perform a DOM operation (I will not recommend) then you can pass $event and style $event.currentTarget in order to perform some operation on that DOM object.
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
Hej, how do I show only the first number that evaluates to true inside ng-repeat?
In my directive (or controller) I have:
ctrl.things = [1,2,3,4,5,6];
and in my html:
<div ng-repeat='thing in ctrl.things' >
<span ng-if="thing>3" ng-show="$first">{{thing}}</span>
</div>
How do I display only 4 as a result?
Please bear in mind that this example is simplified. There is actually an ng-repeat inside ng-repeat and because of that (and other things) there are not many things I co do inside the directive (controller). Many thanks for any solution.
Declare a method in the scope
$scope.getData=function(obj){
return obj > 3;
}
Then add this as filter in div
<div ng-repeat='thing in things | filter : getData' ng-if="$first">
<span >{{thing}}</span>
</div>
JSFIDDLE
If wanna to use this
Try like this
Declare a method in the scope
vm.getData=function(obj){
return obj > 3;
}
Then add this as filter in div
<div ng-repeat='thing in vm.things | filter : vm.getData' ng-if="$first">
<span >{{thing}}</span>
</div>
JSFIDDLE
You should have to create a filter or inline it like this:
<div ng-repeat='thing in ctrl.things' ng-if="thing > 3">
<span ng-if="$first">{{thing}}</span>
</div>
That should work
I think you are looking for this:
//controller
$scope.ctrl={};
$scope.ctrl.things=[{1:false},{2:false},{3:false},{4:true},{5:true}];
$scope.check=function(value){
$scope.count = value === true?($scope.count+1):$scope.count;
return $scope.count ===1 ;
}
//end of controller
HTML
<div ng-repeat='(key,value) in ctrl.things' >
<span ng-if="check(value)">{{key}}</span>
</div>
To show first element if you want to show last item you can put ng-if="$last"
i repeat things in ng repeat like so
<div class="" ng-repeat="deutscheBankEvent in deutscheBankEvents">
<div class="schrottler-opened schrottler" title="">
<span class="presse_ueber" style="font-size:22px;margin-left:10px;font-weight: normal;margin-top:5px">{{deutscheBankEvent.name}}</span>
</div>
<!-- data-ng-repeat also possible-->
<div class="">
<div class="presse_content">
<Div style="color:white">{{deutscheBankEvent.name}}</div>
<ul class="liste_k">
<li ng-repeat="list in deutscheBankEvent.list">
{{list}}
</li>
</ul>
</div>
</div>
later down the code comes up a form to register to events. the form is hidden until user selects a place and date via select. this is triggered like so:
<span ng-show="myForm.locationDate.$valid">
my issue now is: this shows up all hidden form elements when one select is valid.
how can i set the scope to only this one changed?
Since ng-repeat creates a new scope, changing ng-show/ng-hide conditions to scope bound properties will work perfectly (example).
