Ionic , angular , Show or disable a component within controller - angularjs

I have the following code. The following code displays 5 tag item.
What I wanted to do is when user click on any of the tag item, it will be hidden or blank-out. But when I clicked on any of it, all the tag item got blanked out instead of the item I selected. Can anyone give me some idea ?
<div data-ng-repeat="x in mylist">
<a class="button" ng-click="hideme();" style="{{visibility}}">{{x}}</a>
</div>
.controller('MyCtrl', function($scope, $stateParams, chats) {
$scope.hideme = function(index, value) {
$scope.visibility = "background-color: #000000 !important;";
}
});

Firstly, you might want to change your object structure a bit. Remeber always have a dot (.) in your model value.
Try this.
<div ng-app ng-controller="myCtrl">
<div ng-repeat="x in myList">
{{x.value}}
</div>
</div>
function myCtrl($scope){
$scope.myList = [{
value: "a"
}, {
value: "b"
}, {
value: "c"
}];
$scope.hide = function(obj){
obj.hide = true;
}
}

ng-click inside ng-repeat doesnt work

I have html which looks like one below, I have 2x ng-click in whole code in both situation I call same function. Both functions are in same controller.
<div class="tagselect tagselect--frameless">
<div class="combobox__body combobox__body--open combobox__body--frameless" ng-show="focus">
<ul class="list-unstyled">
<li class="combobox__item" ng-repeat="pos in listCtrl.positions | filter:query as results"
ng-click="listCtrl.choosePosition(pos)">{{pos.name}}
</li>
</ul>
</div>
</div>
<div class="col-md-2 no-padding">
<button type="button" class="btn btn-success" ng-click="listCtrl.chosenPositions(789456)">Add</button>
</div>
controller looks like:
myApp.controller('ListCtrl', ['$scope', '$cookies', '$http', function ($scope, $cookies, $http) {
var listCtrl = {
candidates: [],
positions: [],
chosenPositions: [],
init: function () {
listCtrl.getCandidates();
listCtrl.getPositions();
},
getCandidates: function () {
$http.get('candidates.json').then(function (res) {
listCtrl.candidates = res.data;
});
},
getPositions: function () {
$http.get('positions.json').then(function (res) {
listCtrl.positions = res.data;
});
},
choosePosition: function (position) {
console.log(position);
}
};
listCtrl.init();
$scope.listCtrl = listCtrl;
}]);
I double check for missspells and make sure its not because of function (I create a new one with simple console log).
Problem is that button click correctly call function but ng-repeat <li ng-click=""> doesnt do anything. I read in angular documentation that ng-repeat create new scope but this should be still okey in my opinion as soon as I use reference to object listCtrlchoosePosition()
Can someone tell me what I am doing wrong?
Thanks
EDIT: Plunker example:
http://plnkr.co/edit/ooUQA2n1Vyj8RZtsQ1Pj?p=preview
ng-blur is doing something weird, so I'm going to suggest you to change the $scope.focus value from the ListCtrl instead of using the ng-blur.
html file
<!-- more html code -->
<!-- input without ng-blur directive -->
<input class="tagselect__input" placeholder="Position" ng-focus="focus=true" ng-model="query">
<!-- more html code -->
<li class="combobox__item" ng-repeat="pos in listCtrl.positions | filter:query as results" ng-click="listCtrl.choosePosition(pos)">{{pos.name}}
<!-- more html code -->
js file
// more code goes here.
choosePosition: function (position) {
//alert('Going to choosen position');
//$scope.query = position.name;
$scope.focus = false; // Hide div options from here.
// rest of your code.
},
// more code goes here.

How to apped a `directive` by click

Say, I have multiple directives, on click how can i add the "directive" what i want to "popup". i have number of scenario, but using only one pop-up for all. whenever the appropiate element is clicked, using the same pop-up, i would like to update the other 'directives'
for sample, i created only one. click on the red bordered title
here is my code :

How to display custom layout with ng-repeat

Edit: My original question was not good enough, so edited it now.
Hi Im new to angular and im trying to display a custom Layout
for my data list with ng-repeat. I cant use ng-class, as I would like to display diffent model vaules too.
I implemented a function in my controller, that calculates true or false according to my desired design. Then im trying to use ng-if to display my desired HTML with the data. The way I implemeted seems a bit awkward, especially if the layout gets more complicated, is there a better way to achieve this behaviour?
Here a sample: http://plnkr.co/edit/puE7OE?p=info
Controller:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.eventModels=[{name:'event1', description: 'description1'}, {name:'event2', description: 'description2'},
{name:'event3', description: 'description3'}, {name:'event4', description: 'description4'},
{name:'event5', description: 'description5'}, {name:'even6', description: 'description6'}, {name:'even7', description: 'description7'}];
var counter = 0;
this.isLarge = false;
$scope.isLargeContainer = function() {
if(counter === 0) {
this.isLarge = true;
counter++;
} else {
this.isLarge = false;
if(counter === 2) {
counter = 0;
} else {
counter++;
}
}
};
});
View:
<body ng-controller="MainCtrl">
<section ng-repeat="(key, eventModel) in eventModels" >
<div ng-init="isLargeContainer(eventModel)"></div> <!--the only way I found to call a function within the repeat directive.-->
<div ng-if="isLarge">
<!--Display large content -->
<p class='large'>my large event: {{eventModel.name}}, {{eventModel.description}}</p>
</div>
<div ng-if="!isLarge">
<!--Display content small-->
<p class='small'>{{eventModel.name}}</p>
</div>
</section>
</body>
Thanks a lot in advance!
Im using Anguler 1.3.3
I just solved your problem. You can find the solution here:
http://jsfiddle.net/anasfirdousi/46saqLmw/
Here is the HTML
var myApp = angular.module('myApp',[]);
function myController($scope){
$scope.msg = 'Learning Angular JS ng-class Directive';
$scope.menu = [ 'Menu Item 1','Menu Item 2','Menu Item 3','Menu Item 4'];
}
.large {
font-size:16px;
}
body{
font-size:12px;
}
<div ng-app="myApp" ng-controller="myController">
{{ msg }}
<ul>
<li ng-repeat="(key, value) in menu" ng-class="{'large': $index==2 }"> {{ value }} </li>
</ul>
</div>
In your case, you actually have to use ng-class with expressions. The class is applied only if the condition holds true.
http://jsfiddle.net/anasfirdousi/cuo6cn3L/
Check the above link. This is another example if you want to do it on any specific condition. You can call a function which checks a condition and returns either a true or a false rather than using an inline expression.
var myApp = angular.module('myApp',[]);
function myController($scope){
$scope.msg = 'Learning Angular JS ng-class Directive';
$scope.menu = [ 'Menu Item 1','Menu Item 2','Menu Item 3','Menu Item 4'];
$scope.CheckSometing = function(v){
if(v=='Menu Item 3'){
return true;
}
else
{
return false;
}
}
}
.large {
font-size:16px;
}
body{
font-size:12px;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myController">
{{ msg }}
<ul>
<li ng-repeat="(key, value) in menu" ng-class="{'large': CheckSometing(value) }"> {{ value }} </li>
</ul>
</div>

Access child scope corresponding to a model variable

I have a list of items and I've rendered them in a template via ng-repeat. Each of them is controlled by an itemController which exposes some behavior for item (e.g. grabing focus). Here is the HTML:
<body ng-controller="mainController">
<button ng-click="addItem()">add</button>
<ul>
<li ng-repeat="item in items" ng-controller="itemController">
<div ng-if="item.isEditing">
<input ng-model="item.name"/>
<button ng-click="item.isEditing=false">done</button>
</div>
<span ng-if="!item.isEditing">{{item.name}}</span>
</li>
</ul>
</body>
In the mainController, I have a function for adding a new item to items. Here is the code for mainController:
app.controller('mainController', function($scope){
$scope.items = [
{
name: "alireza"
},
{
name: "ali"
}
];
$scope.addItem = function(){
$scope.items.push({isEditing: true});
}
});
Whenever I add an item to items array, a corresponding li element is added into the view which is controlled by an instance of itemController, and the corresponding model is the new item I've just added (or maybe the scope of the itemController, which contains item).
Problem:
When I add some item to items, I only have access to item and not the scope of the recently created item. So I can't run some function (like grabFocus) on the scope of new item.
Is it something semantically wrong in my design? What is the canonical approach for this problem?
Plunker link
Here is the plunker link with related comments
You can use $broadcast from the parent scope, along with $on from the child scope, to notify the child scopes of the newly added item. And by passing (as an argument) the $id of the child scope that corresponds to the newly added item, each child catching the event can know whether or not it's the one that needs to have grabFocus() called.
Here's a fork of your Plunker that uses that approach. I wasn't sure what you were trying to accomplish with $element.find(":text").focus(); in your original Plunker, so I tweaked it to toggle a $scope property that in turn controlled a style in the view. The newly added item will be red (by calling its own grabFocus function to toggle the flag to true), and the others will be black (by calling their own loseFocus function to toggle the flag to false).
Modified HTML (just the repeated li):
<li ng-repeat="item in items" ng-controller="itemController">
<div ng-if="item.isEditing">
<input ng-model="item.name"/>
<button ng-click="item.isEditing=false;handleItemAdded($index);">done</button>
</div>
<span ng-if="!item.isEditing" ng-style="{ color: isFocused ? 'red' : 'black' }">{{item.name}}</span>
</li>
Full JavaScript:
var app = angular.module("app",[]);
app.controller('mainController', function($rootScope, $scope){
$scope.items = [ { name: "alireza" }, { name: "ali" } ];
$scope.addItem = function(){
$scope.items.push({isEditing: true});
};
$scope.handleItemAdded = function (index) {
// $rootScope.$broadcast('item-added', { index: index });
for(var cs = $scope.$$childHead; cs; cs = cs.$$nextSibling) {
if (cs.$index === index) {
$rootScope.$broadcast('item-added', { id: cs.$id });
break;
}
}
};
});
app.controller('itemController', function($scope, $element){
$scope.$on('item-added', function (event, args) {
if ($scope.$id === args.id + 1) {
$scope.grabFocus();
} else {
$scope.loseFocus();
}
});
$scope.grabFocus = function() {
$scope.isFocused = true;
};
$scope.loseFocus = function() {
$scope.isFocused = false;
};
});
I changed your approach a little bit by creating an unique id for every input, based on its index number. See code below, hope it helps.
// Code goes here
var app = angular.module("app",[]);
app.controller('mainController', function($scope,$timeout){
$scope.items = [
{
name: "alireza"
},
{
name: "ali"
}
];
$scope.addItem = function(){
$scope.items.push({isEditing: true});
$timeout(function(){
document.getElementById("newItem"+($scope.items.length-1)).focus();
},0)
}
});

Adding directive dynamically using ng-click

I am working on a modal for a client. I have created a directive that works great, the problem is that one modal is made ahead each time it is used like..
What I have
<div ng-repeat="item in items">
<a data-toggle="modal" data-target="{{item.id}}">Click</a>
<my-dialog element-id="item.id">
<h1>This is the body of the modal</h1>
</my-dialog>
</div>
This works great for a small amount of modals but we are using a very large number of modals. So I would like to add the directive at runtime, something closer to...
What I want...
<div id="warning"></div>
<div ng-repeat="item in items">
<a data-toggle="modal" data-target="{{item.id}}" ng-click="showModal(item)">Click</a>
</div>
...
// inside controller
$scope.showModal = function(item){
$http.get('/someUrl').success(function(data){
var result = $compile('<my-dialog element-id="'+item.id+'">'+data+'</my-dialog>').($scope);
$("#warning").append(result);
});
}
$scope.hideModal = function(){
$( "#warning" ).empty();
}
This of course isn't working yet. Also it doesn't feel like the best way. This would allow me to remove the directive once it has been closed.
Please include a plunker or equivalent for the check.
One way you could do this is to use ng-repeat with your items, then call $scope.$apply() after you push a new item to the list. The HTML could look like this ...
<div ng-repeat="item in items">
<span dialog>
<a class="dialog-anchor">{{item.name}}</a>
<div class="dialog-body">{{item.id}}</div>
</span>
</div>
... and the directive like this
.directive('dialog', [function () {
return {
scope: {
id: '#elementId',
}
, link: function (scope, el, attrs) {
var body = $(el).find('.dialog-body').detach();
$(el).find('.dialog-anchor').on('click', function () {
$('body').append(body);
});
}};
}])
... and the controller like this
.controller('app', ['$scope', function ($scope) {
$scope.items = [
{name: 'first', id: 001},
{name: 'second', id: 002}
];
setTimeout(function () {
$scope.items.push({name: 'three', id: 003});
if (!$scope.$$phase) $scope.$apply();
}, 2000);
}])
Here's the plunker... http://plnkr.co/edit/2ETbeCKGcHW3CJCfD9d7?p=preview. You can see the $scope.$apply call in the setTimeout where I push a new item to the array.
Try this:
var result = $compile('<my-dialog element-id="'+item.id+'">'+data+'</my-dialog>')($scope);
