Target only 1 button in Angular

Im getting the values in a div from the DB and displaying using ng-repeat:
<div ng-controller = "myTest">
<div ng-repeat="name in names">
<h4>{{name.name}}</h4>
<button ng-class="{'active': isActive}" ng-click="test()" >me</button>
</div>
</div>
In my controller I have:
$scope.test= function(){
$scope.isActive = !$scope.isActive;
}
I have defined a class isActive in my css and that is applied/removed to the button on click. There are 5 results so 5 divs are created cause of ng-repeat and 5 buttons(1 for each respective div). The problem is that every button (all 5 of them) is getting that class. I want the class to be applied/removed only to the button clicked. How can I achieve this?

You can try something like this :
<div ng-controller="myTest">
<div ng-repeat="name in names">
<h4>{{name.name}}</h4>
<button ng-class="{ active : name.isActive }"
ng-click="name.isActive = !name.isActive">me</button>
</div>
</div>
Hope this will help.

You need to keep track of each button status.
One way will be to passing the name or anything that uniquely identify the button to your function:
<div ng-controller = "myTest">
<div ng-repeat="name in names">
<h4>{{name.name}}</h4>
<button ng-class="{'active': buttons[name].isActive}" ng-click="test(name)" >me</button>
</div>
</div>
$scope.buttons = {};
$scope.test= function(name){
$scope.buttons[name].isActive = !$scope.buttons[name].isActive;
}

I created a plunk that answers this question without modifying your source array.
Your function becomes
vm.test = function(buttonIndex) {
//Clear the class if you press the same button again
if (vm.buttonIndex === buttonIndex) {
vm.buttonIndex = undefined;
} else {
vm.buttonIndex = buttonIndex;
}
};
And your HTML is
<div ng-repeat="name in main.names track by $index">
<h4>{{name.name}}</h4>
<button ng-class="{'active': main.buttonIndex===$index}" ng-click="main.test($index)">me</button>
</div>

accessing other scope variables inside custom template

I'm trying to display files inside each folder/directory.
I'm using custom directive to disply each of the directories as follows (this part works).
But it fails to resolve the {{file}} variable inside custom template folderListing.html. Can somebody please correct me where I'm going wrong ?
folderListing.js
app.directive('folderListing', function(){
return {
restrict: 'E',
scope: {
listing:'='
},
templateUrl: 'js/directives/folderListing.html'
};
});
RdaController.js
app.controller('RdaController', ['$scope','RdaService', function($scope,RdaService) {
$scope.folders = ['RDA Server Folder','CTP Outbox', 'CTP Inbox', 'CTP Jobs'];
$scope.sendToCTP = function(file){
return RdaService.SendFileToCTP(file);
};
$scope.listOfFiles = ['learn_javascript.pdf', 'HTML Made Easy.pdf', 'AngularJS for everybody.pdf'];
}]);
index.html
<folder-listing listing="folder" ng-repeat="folder in folders"></folder-listing>
folderListing.html
<div class="row">
<div class="col-md-3" id="{{listing}}">
<table class="table table-striped">
<h3> {{ listing }} </h3>
<div class="row">
<div class="col-md-3" ng-repeat="file in listOfFiles">
{{file}}
</div>
</div>
<td><span class="btn-group" role="group"><button type="button" class="btn btn-default" ng-click="sendToCTP(file)">Execute</button></span></td>
</table>
</div>
</div>

With this:
scope: {
listing:'='
},
You have created an isolate scope passing only listing to the directive. You need to change this to:
scope: {
listing: '=',
listOfFiles: '=',
sendToCTP: '&sendToCtp'
},
To pass the function you'll have to add a send-to-ctp="sendToCTP(file)" attribute on your directive. However, in your template your button with ng-click="sendToCTP(file)" is outside your ng-repeat so file will always be undefined.

Pass object to isolated directive

When my application loads a function to get items from a server runs, this function get the title and Id of all items on the server,
then puts them in an array.
In my main html I have a table that displays this array, and when i click the title of an Item, I call another function (onView)
which gathers more information about that item from the server. This new information is passed to
a variable called '$scope.currentItem'.
I also have a directive called 'currentItem', this is used to display that item for the user.
myApp.directive('currentItem',function(){
return{
restrict:'E',
scope:{
data:'='
},
templateUrl: 'currentItem.html',
controller:function($scope){
}
};
});
To know if a user has clicked an item I have a boolean called isView, so when the function to gather more information runs
the isView is set to 'true'.
My html looks like this:
<div ng-app="myApp">
<hr>
<div ng-controller="appCtrl">
<div ng-hide="isView" class="col-md-12">
<table id="mainTable" ng-table="tableParams" class="table">
<tbody ng-repeat="item in items">
<tr>
<td id="Title" data-title="'Title'">
{{item.id}} |<a ng-click="onView(item.id)">{{item.title}}</a>
</td>
<td data-title="'Description'">
{{item.description | date:'dd-MM-yyyy'}}
</td>
<td data-title="'Created'">
{{item.created | date:'dd-MM-yyyy'}}
</td>
</tr>
</tbody>
</table>
</div>
<div ng-show="isView" class="col-md-12">
<current-item data="currentItem"></current-item>
</div>
</div>
</div>
This can't be the correct way to pass an object to a directive, seeing I always use the same 'currentItem' object.
How could I improve this, so that each object is isolated and editable in a seperate view?

Angular, share directive template between click functions

I have a directive which, when called, passes in a controller and an array.
In the controller I pass in, there is an object I want to loop over.
my html looks like this:
<div class="row">
<div class="col-md-6">
<div class="jumbotron" ng-controller="protocolCtrl as pctrl">
<button type="button" id="protocol" class="btn btn-primary btn-lg" ng-click="pctrl.getUpdatedList()"
data-toggle="modal" data-target="#modal">Modify Current Protocols</button>
<!--IN THIS MODAL YOU CAN ADD/CHANGE/DELETE DATA-->
<modal-directive list="pctrl" headers="['ID', 'Protocol']"></modal-directive>
</div>
</div>
<div class="col-md-6">
<div class="jumbotron" ng-controller="categoryCtrl as cctrl">
<button type="button" id="category" class="btn btn-primary btn-lg" ng-click="cctrl.getUpdatedList()"
data-toggle="modal" data-target="#modal">Modify Current Categories</button>
<!--IN THIS MODAL YOU CAN ADD/CHANGE/DELETE DATA-->
<modal-directive list="cctrl" headers="['ID', 'Category']"></modal-directive>
</div>
</div>
</div>
My problem is that no matter what I do, it's always the FIRST directive in the html that showes up, no matter what button I press.
My directive looks like this:
.directive('modalDirective', function(){
return {
restrict: 'E',
templateUrl: '/directives/modal-directive.html',
scope: {
list: '=',
headers: '='
},
link: function(scope, element, attrs){
console.log(attrs.list + ' | ' + attrs.headers);
}
};
});
My modal-directive.html looks like this:
<table class="table table-striped">
<thead>
<tr>
<th ng-repeat="h in headers"> {{ h }} </th>
</tr>
</thead>
<tbody>
<!-- Loop through -->
<tr ng-repeat="l in list.list">
<!--Access the actual values inside each of the objects in the array-->
<td ng-repeat="data in l"> {{ data }} </td>
<td>
<button type="button" class="btn btn-primary btn-sm"
data-toggle="modal">Edit</button>
</td>
<td>
<button type="button" class="btn btn-danger btn-sm" ng-click="list.removeData(l)"
data-dismiss="modal">Remove</button>
</td>
</tr>
</tbody>
</table>
Am I using isolated scopes wrong, or is it something else I need to change in order to make this work?
Update
Here is a fiddle, that demonstrates the problem.
No matter which button i click, it displays the same text in the modal body.

You don't really need two controllers and two directives to achieve this. Below is an example of how you can do this. Notice I moved the controller to the row instead of having separate controllers for each column. The controller myCtrl now handles the click functions which are bound to the buttons using the ng-click attribute. This then determines the which text should be placed where by calling there respective functions. IE proto() and cat()
Now this may not be ideal for your situation depending on how you plan on the architecture of your application. But it works for your current problem in terms of what you have provided.
HTML
<body ng-app="TM">
<div class="row" ng-controller="myCtrl as modalControl">
<div class="col-md-6">
<div class="jumbotron" >
<button
ng-click='proto()'
type="button" id="protocol"
class="btn btn-primary btn-lg"
data-toggle="modal"
data-target="#modal">Modify Current Protocols
</button>
</div>
</div>
<div class="col-md-6">
<div class="jumbotron">
<button
ng-click='cat()'
type="button"
id="category"
class="btn btn-primary btn-lg"
data-toggle="modal"
data-target="#modal">Modify Current Categories
</button>
</div>
</div>
<!--IN THIS MODAL YOU CAN ADD/CHANGE/DELETE DATA-->
<modal-directive ctrl="modalControl"></modal-directive>
</div>
</body>
Angular JS
angular.module('TM', [])
.controller('myCtrl', function($scope){
$scope.text ='default';
$scope.proto = function() {
this.text = 'Now looking at the protocol part'
}
$scope.cat = function() {
this.text = 'Now looking at the category part'
}
})
.directive('modalDirective', function(){
return {
restrict: 'E',
scope: true,
template: ['<div id="modal" class="modal fade" role="dialog">',
'<div class="modal-dialog">',
'<div class="modal-content">',
'<div class="modal-header">',
'<h4 class="modal-title">Modal Header</h4>',
'</div>',
'<div class="modal-body">',
'<p> {{ text }} </p>',
'</div>',
'<div class="modal-footer">',
'<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>',
'</div>',
'</div>',
'</div>',
'</div>'].join('')
}
});

UPDATE:
Okay, I took another look. And even though the above example works. I noticed that I have a few extra things that I didn't necessarily need. For example myCtrl as modalControl doesn't need the as modalControl part. Below is an updated example. I did this one with some different simplified markup.
HTML:
<body ng-app="TestApp">
<div ng-controller="myCtrl">
<button ng-click="one()">One</button>
<button ng-click="two()">Two</button>
<test-directive></test-directive>
</div>
</body>
Angular Example (without Isolated Scope)
angular.module('TestApp', [])
.controller('myCtrl', function($scope){
$scope.text ='default';
$scope.one = function() {
this.text = 'this is one'
}
$scope.two = function() {
this.text = 'this is two'
}
})
.directive('testDirective', function(){
return {
template: "<div id='test'>{{text}}</div>"
}
});
Demo 2:
https://jsfiddle.net/krishollenbeck/v8tczaea/12/
Note this..
restrict: 'E',
scope: true
Was also not needed because I am not using Isolated scope in this example. More info here https://docs.angularjs.org/guide/directive

Please check this JSFiddle.
The reason is that data-target value points to the DOM element id of the modal. If you fixed this id in the directive template, clicking on the button will always initiate the modal with id modal. So you need to make the modalId as another parameter of the directive.
By the way, you can pass a controller to a directive. Just like this JSFiddle:
angular.module('Joy', [])
.controller('MyCtrl', ['$scope', function ($scope) {
this.value = 'Joy';
}])
.directive('passMeContrller', [function () {
return {
restrict: 'A',
scope: {
ctrl: '=',
},
template: '<div>Value: {{ctrl.value}}</div>'
};
}]);
The HTML:
<div ng-app="Joy" ng-controller="MyCtrl as c">
<div pass-me-contrller ctrl="c"></div>
<hr>
<div ng-bind="c.value"></div>
</div>
Because the controller itself is just a JavaScript object.
Just a reminder: you are using protocolCtrl as pctrl, so you need to specify like this.list=....
If you want to pass in a function to the isolated scope, use &.
However, I suggest not to pass in the whole controller to a directive. A controller is designed to:
Set up the initial state of the $scope object.
Add behavior to the $scope object.
Controllers are not supposed to be reused. Usually there are many properties on the $scope, while some of them passed to the directive will not be used by it.

check value of isolated scope variable in link function - directives in angular

I have the following html:
<div class="jumbotron" ng-controller="protocolCtrl as pctrl">
<!--IN THIS MODAL YOU CAN ADD/CHANGE/DELETE DATA-->
<modal-directive list="pctrl" headers="['ID', 'Protocol']"></modal-directive>
</div>
In my modal-directive.html, in the body, I do this:
<!-- Modal body-->
<div class="modal-body">
<table-directive list=list headers=headers></table-directive>
</div>
I want to check on the list parameter i pass in. if it's equal some value, I want to append some html to the body
My directive looks like this
.directive('modalDirective', function(){
return {
restrict: 'E',
templateUrl: '/directives/modal-directive.html',
scope: {
list: '=',
headers: '='
},
link: function(scope, element, attrs){
if(scope.list == 'pctrl'){
element.find('.modal-body').append('This is just a test.')
}
}
};
});
But this doesn't append anything. If I drop the if check it appends just fine.
I'm fairly new to angular, so if anyone can tell me how I can achieve this, I'd appreciated it.
Edit
this is how i loop through the data in my table-directive.html
<tr ng-repeat="l in list.list">
<!--Access the actual values inside each of the objects in the array-->
<td ng-repeat="data in l"> {{ data }} </td>
<td>
<button type="button" class="btn btn-primary btn-sm"
data-toggle="modal">Edit</button>
</td>
<td>
<button type="button" class="btn btn-danger btn-sm" ng-click="list.removeData(l)"
data-dismiss="modal">Remove</button>
</td>
</tr>

if you put
<modal-directive list="pctrl" headers="['ID', 'Protocol']"></modal-directive>
and
....
scope: {
list: '=',
headers: '='
},
.....
list: '=' check for the list attr of the element and execute the argument as a expression not as a string i think your trying to get 'pctrl' as a string not as a scope variable value so that change to list="'pctrl'" to pass as a string
<modal-directive list="'pctrl'" headers="['ID', 'Protocol']"></modal-directive>
OR
get the attr as a string use #
....
scope: {
list: '#',
headers: '='
},
.....
here is a good Explanation.
here is the angular official DOC
update
if you need to check only the string value of the attr, then you can simply use attrs.list
so use it inside the directive as
if(attrs.list === 'pctrl'){
element.find('.modal-body').append('This is just a test.')
}
