Angular.js is pretty new to me. I have learned before the $scope method for the controller and now trying the "this" method. For some reason I can not get my ng-repeat to work. here's my code:
HTML:
<ul class="nav nav-pills">
<li><a ng-click="myCtrl.tab=1" href>one</a></li>
<li><a ng-click="myCtrl.tab=2" href>two</a></li>
<li><a ng-click="myCtrl.tab=3" href>three</a></li>
</ul>
<div ng-controller="imageContr as imageCtrl">
<div ng-show="myCtrl.tab === 1" class="tab">
<h3>ONE title</h3>
<p>hello</p>
<li ng-repeat="item in gallery">
<img alt="imagealt" ng-src="{{item.photo}}">
</li>
</div>
<div ng-show="myCtrl.tab === 2" class="tab">
<h3>TWO title</h3>
<p>how are</p>
</div>
<div ng-show="myCtrl.tab === 3" class="tab">
<h3>THREE title</h3>
<p>you?</p>
</div>
</div>
</section>
</body>
</html>
APP.JS:
(function() {
var app = angular.module('myApp', []);
app.controller('myController', function() {
this.tab = 1;
});
app.controller('imageContr', function() {
this.gallery = images;
var images = {
photo: 'image1.jpg'
};
});
})();
Declare images before you assign it, and make it an array
var images = [{ photo: 'image1.jpg' }];
this.gallery = images;
Then in your view:
<li ng-repeat="item in imageCtrl.gallery">
<img alt="imagealt" ng-src="{{item.photo}}">
</li>
You are storing the gallery on this of the controller (which is basically the $scope), hence you need to access it in the template via imageContr as well:
<li ng-repeat="item in imageCtrl.gallery">
<img alt="imagealt" ng-src="{{item.photo}}">
</li>
You could also consider making gallery an array, so can easily iterate over it. Or you need to use the "iterate over object properties"-syntax:
<div ng-repeat="(key, value) in myObj"> ... </div>

I'm creating a menu that on ng-click= i am getting the variable and than on ng-class setting that variable to true for the menu and the content.
Goal is on click to add/remove an active class to the parent and to the content div.
can't get my head around this one
<div ng-controller="myCtrl">
<ul>
<li class="animate" ng-class="{activelist: fonts ==!hidden }">
<a ng-click="activeMenu('fonts')" class="nav-icon">
menu font
</a>
</li>
<li class="animate" ng-class="{activelist: edit ==!hidden }">
<a ng-click="activeMenu('edit')" class="nav-icon">
menu edit
</a>
</li>
<ul>
<div class="">
<div class="fonttext" ng-class="{activelist: fonts ==!hidden }"></div>
<div class="edittext" ng-class="{activelist: edit ==!hidden }" ></div>
</div>
</div>
<script>
var myapp = angular.module('app', []);
myapp.controller('myCtrl', function($scope){
$scope.activeMenu = function (menuvar){
//getting the variable that gets passed via func
$scope.variable = menuvar;
// set the variable to be true no working
$scope.menuvar = true;
}
});
</script>
You can set a variable directly in ng-click to true. This variable can then be used in ng-class to dynamically add or remove classes. Here is an example:
<li class="animate" ng-class="{'activelist': fonts }">
<a ng-click="fonts = !fonts" class="nav-icon"></a>
</li>
<li class="animate" ng-class="{'activelist': edit }">
<a ng-click="edit = !edit" class="nav-icon"></a>
</li>
You can also set the variable in the controller:
HTML:
<li class="animate" ng-class="{'activelist': menu.fonts }">
<a ng-click="switchMenu('fonts')" class="nav-icon"></a>
</li>
<li class="animate" ng-class="{'activelist': menu.edit }">
<a ng-click="switchMenu('edit')" class="nav-icon"></a>
</li>
Controller:
$scope.menu = {};
$scope.switchMenu = function(selectedMenu) {
$scope.menu[selectedMenu] = !$scope.menu[selectedMenu];
};
How can I get the selected value from below dropdown.?
<ul class="nav-drop-menu" id="ddlHotelSort">
<li class="liselect" value="{{ssort.Sort}}" ng-repeat="ssort in vm.searchsort">
<a href="javascript:void(0)" class="SortClass" name="Sortclass" style="left:0px" value="{{ssort.Sort}}">{{ssort.Name}}
</a>
</li>
</ul>
Below is image of dropdown opening..
How can I handle event and model value in angular application..?
<ul class="nav-drop-menu" id="ddlHotelSort">
<li class="liselect" ng-click="getSelectedItem(ssort);" value="{{ssort.Sort}}" ng-repeat="ssort in vm.searchsort">
<a href="javascript:void(0)" class="SortClass" name="Sortclass" style="left:0px" value="{{ssort.Sort}}">{{ssort.Name}}
</a>
</li>
</ul>
controller function
$scope.getSelectedItem = function(item){
console.log(item);//selected item
}
Just call a function in the li click, here is an example with your options.
Just click on each li,
var app=angular.module('myApp',[])
app.controller('MyCtrl',MyCtrl)
function MyCtrl($scope) {
$scope.opts = ["Recommended","FirstClass","SecondClass","ThirdClass" ];
$scope.my_method = function(opt)
{
alert(opt)
}
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>
<div ng-app ng-controller="MyCtrl">
<ul>
<li ng-repeat=" opt in opts" ng-click="my_method(opt)">
{{ opt }}
</li>
</ul>
<p>{{opt}}</p>
</div>
Run the code snippet and click on each li
HEre is an example fiddle with your options
I wanna see a div when I put the mouse over an image and remove it if I leave the mouse, with the ng-mouseenter and ng-mouseleave. But when I load my page, in the div appear class="ng-hide".
My code:
<nav class="navbar-default navbar-side" role="navigation" ng-app="panel" ng-controller="panelController">
<div class="sidebar-collapse">
<ul class="nav" id="main-menu">
<li class="text-center">
<img ng-mouseenter="inProfile()" ng-mouseleave="outProfile()" src="{{ asset('image/id1.jpg') }}" class="user-image img-responsive"/>
<div ng-show="panelController.evento">
Hi!!
</div>
</li>
<li>
<i class="fa fa-dashboard fa-3x"></i><span class="text-20">Dashboard</span></a>
</li>
<li>
<i class="fa fa-users fa-3x"></i><span class="text-20">Usuarios</span>
</li>
<li>
<i class="fa fa-lightbulb-o fa-3x padding-left-10"></i><span class="text-20 padding-left-10">Emprendedores</span></a>
</li>
<li>
<i class="fa fa-money fa-3x"></i><span class="text-20">Inversores</span></a>
</li>
<li>
<i class="fa fa-newspaper-o fa-3x"></i><span class="text-20">Noticias</span></a>
</li>
</ul>
</div>
</nav>
<script>
var tfc = angular.module('panel', []);
tfc.controller ( 'panelController' , [ '$scope' , function($scope){
$scope.inProfile = function(){
$scope.evento = "true";
}
$scope.outProfile = function(){
$scope.evento = "false";
}
}])
</script>
You problem is on page load eventto value is undefined that's why ng-show expression is hiding value on page load. you should define evento value to true to show it. You could this do from controller or also you could use ng-init="panelController.evento=true" on view
And make sure, you should use boolean rather than string which is used for expression evaluation in ng-show.
Code
var tfc = angular.module('panel', []);
tfc.controller('panelController', ['$scope', function($scope) {
$scope.inProfile = function() {
$scope.evento = true;
}
$scope.outProfile = function() {
$scope.evento = false;
}
//init values
$scope.evento = true;
}]);
Update
You should directly access value of scope variable on view as you are not using controllerAs in you application, it should be evento instead of panelController.evento

<div ng-show="evento">
Hi!!
</div>
So I ma trying to loop through an array and create an list item for each object in it.
However when then adding an ng-click to that item i get the following error, even though the code prints out correctly.
Syntax Error: Token '$index' is unexpected, expecting [:]
I have the following code:
<body ng-controller="VideoController as VidCtrl">
<div class="row" id="grid">
<div ng-repeat="array in videos" ng-show="VidCtrl.isActive({{$index}})">
<ul class="small-block-grid-3">
<li ng-repeat="video in array" ng-click="VidCtrl.setVideo({{$index}})">
<img src="{{video.image}}">
<div>
<h5>{{video.title}}</h5>
<p>{{video.ingress}}</p>
</div>
</li>
</ul>
</div>
<ul class="pagination">
<li ng-class="{'current':isActive($index)}" ng-repeat="array in videos"><a ng-click="VidCtrl.setPanel($index)" href="#">{{$index + 1}}</a></li>
</ul>
</div>
And This is my js:
var videos = [];
var activeVideo = null;
var app = angular.module('webb-tvApp', []);
app.controller('VideoController', function($scope){
$scope.videos = videos;
this.activePanel = 0;
this.setPanel = function(val){
this.activePanel = val;
}
this.isActive = function(val){
return this.activePanel === val;
}
this.setVideo = function(vidIndex){
console.log(videos[this.activePanel][vidIndex]);
}
});
The videos array has the following structure.
var videos = [
[
{
image: "foo",
title: "bar",
ingress: "foobar",
},
{},
{}
],
[
{},
{},
]
]
I am new to angular so go easy on me.
When using these directives you can use the variables without interpolation {{}}. Additionally, you can use ng-src with your images instead of using src.
<body ng-controller="VideoController as VidCtrl">
<div class="row" id="grid">
<div ng-repeat="array in videos" ng-show="VidCtrl.isActive($index)">
<ul class="small-block-grid-3">
<li ng-repeat="video in array" ng-click="VidCtrl.setVideo($index)">
<img ng-src="{{video.image}}">
<div>
<h5>{{video.title}}</h5>
<p>{{video.ingress}}</p>
</div>
</li>
</ul>
</div>
<ul class="pagination">
<li ng-class="{'current':isActive($index)}" ng-repeat="array in videos"><a ng-click="VidCtrl.setPanel($index)" href="#">{{$index + 1}}</a></li>
</ul>
</div>
Few things I noticed:
Remove interpolation from inside ng-show and ng-click
<div ... ng-show="VidCtrl.isActive($index)">
...
<li ... ng-click="VidCtrl.setVideo($index)">
And replace src with ng-src
<img ng-src="{{video.image}}">
I have a list of items ("locals" array) which I show in a list
<ul class="list-group">
<li ng-repeat="loc in locals" class="list-group-item"><a href="" data-id={{loc.ID}}>{{loc.location}}</a>
</li>
</ul>
I want the user to be able to select an item, and then to use this item in code.
What is the preferred way to do it.
Also I am creating the application for mobile, so I should be able to know that the user chose this item in mobile( and not just use mouseclick for example).
You can make use of angular js ng-click event (on the li item where ng-repeat is and do something like this: fiddle
code snippet of controller:
function MyCtrl($scope) {
$scope.templateList = [{id:1, name: 'Template1'}, {id:2, name: 'Another Template'}]
$scope.template = {};
$scope.setValue = function(list) {
$scope.template.template_id = list.id;
$scope.template.template_name = list.name;
}
}
Of HTML:
<div ng-app>
<form ng-controller="MyCtrl">
<input type="hidden" name="template_id" ng-model="template.template_id" />
<input type="text" name="template_name" ng-model="template.template_name" />
<ul>
<li ng-repeat="list in templateList" ng-click="setValue(list)">{{list.name}}</li>
</ul>
</form>
</div>
Try this:
In html,
<ul class="list-group">
<li ng-repeat="loc in locals" class="list-group-item">
<a href="" data-id={{loc.ID}} ng-click="selectLoc(loc.location)">
{{loc.location}}
</a>
</li>
</ul>
In JS,
$scope.selectLoc = function(location){
console.log(location);
//Here you will get the selected location.
var SomeVar = location;
}
Hope this helps....
