I am trying to select one item on one time in angularJS.
Here is my code
<div ng-repeat="list in listgroups" >
<ul ng-init="selected = -1">
<li ng-repeat="item in list" ng-class="{active:(selected == $index)}" ng-click="selected = $index;">{{item}} </li>
</ul>
</div>

ng-repeat creates new scope from current scope, so If you are using selected inside a inner ng-repeat will cause to create new scope variable for inner ng-repeat.
If you want to refer the parent scope from ng-repeat then use $parent.selected that will refer the outer scope variable of ng-repeat.
HTML
<div ng-repeat="list in listgroups" ng-init="selected = -1">
<b>List {{$index + 1}}</b>
<ul>
<li ng-repeat="item in list" ng-class="{active:($parent.selected == $index)}"
ng-click="$parent.selected = $index;">
{{item}}
</li>
</ul>
</div>

}
<div ng-app="" ng-controller="testCtrl">

I have used name you can use the value that you want ot test
So I'm trying to create a simple tab system in angularjs, but whenever I try to bind data on ng-click on the a or li tags of my template I get this error:
Syntax Error: Token '' {1} at column {2} of the expression [{3}] starting at [{4}].
I been searching for hours can't figure out what's causing the problem
here's my code:
<div id="tabs">
<ul>
<li ng-repeat="file in files" ng-click="tab = {{$index}}">
{{file.file_name}}.{{file.file_extension}}
</li>
</ul>
</div>
<!-- tab container -->
<div class="tab-content">
<div class="tab" ng-repeat="doc in files" ng-show="tab == {{$index}}">
{{doc.file_name}}.{{doc.file_extension}}
</div>
</div>
I have tried wrapping {{$index}} in single quotes, that fixes the problem but the tabs don't work when clicked.
You could move this out of the inline logic and into a function, for example $scope.setTabIndex, like so:
$scope.setTabIndex = function(index) {
$scope.tab = index;
}
And then in your markup:
<li ng-repeat="file in files" ng-click="setTabIndex($index)">
And for the ng-show, just remove the curly braces around $index:
<div class="tab" ng-repeat="doc in files" ng-show="tab == $index">
Here's as jsBin
<ul class="day">
<li ng-repeat="sessions in day">
<ul class="table-view">
<li class="table-view-cell" ng-repeat="(heading, session) in sessions">
<span class="group">{{heading}}</span>
<ul class="cell">
<li class="cell-content" ng-repeat="val in session" ng-click="session($event, val.id)">
<div class="time" style="background-color:#{{val.color}}">
<span>{{val.start | date:"h:mma"}}</span>
<span>to</span>
<span>{{val.end | date:"h:mma"}}</span>
</div>
<div class="session" ng-class-odd="'odd'" ng-class-even="'even'">
<span class="name">{{val.name}}</span>
<span class="room">Room: {{val.room}}</span>
</div>
</li>
</ul>
</li>
</ul>
</li>
</ul>
I've a nested ng-repeats and within the last inner loop have a function call, the function is defined on $scope but I'm getting the following error.
TypeError: object is not a function
$scope.session = function($event, id) {
console.log(id);
};
not sure if it has to do with nesting of ng-repeats and their scopes.
It has nothing to do with nesting several ng-repeats, but I think it is mixing it up with sessionobject which returns from ng-repeat="(heading, session) in sessions" . Try to change the function name to something else and give it a try.
I am using AngularJS and its ng-repeat directive to display a sequence of questions. I need to number each question starting with 1. How do I display and increment such a counter with ng-repeat? Here is what I have so far:
<ul>
<li ng-repeat="question in questions | filter: {questionTypesId: questionType, selected: true}">
<div>
<span class="name">
{{ question.questionText }}
</span>
</div>
<ul>
<li ng-repeat="answer in question.answers">
<span class="name">
{{answer.selector}}. {{ answer.answerText }}
</span>
</li>
</ul>
</li>
</ul>
Angularjs documentation is full of examples, you just need to take some time and explore it.
See this example here : ngRepeat example , it's the same case.
<ul>
<li ng-repeat="question in questions | filter: {questionTypesId: questionType, selected: true}">
<div>
<span class="name">
{{$index + 1}} {{ question.questionText }}
</span>
</div>
<ul>
<li ng-repeat="answer in question.answers">
<span class="name">
{{answer.selector}}. {{ answer.answerText }}
</span>
</li>
</ul>
</li>
</ul>
Reached here by searching for something similar.
Here is what worked for me.
{{$index + 1}}
+1 is added because the index starts from 0.
There are two ways to get an index for the given array in ng-repeat
Using $index
<th ng-repeat="n in [].constructor(3 + 1) track by $index">{{$index}}</th>
Using a counter
This method is useful when you have nested ng-repeat and you need counters for both loops...the following example uses counter row. Although track by $index is required, it is not used for the logic.
<tr ng-repeat="(row, y) in getNumber(h.seats.length, 3) track by $index">
<td>{{row+1}}</td>
In both cases counter starts with 0 and you can offset using +1 if you like
I have a list of items. An item can be a number of things, let's say the list is something like so :
[userObject , vehicleObject , userObject , animalObject , animalObject]
Now I want to render the list with ngRepeat directive that will use a template according to the type of the object (Polymorphic rendering). can this be done?
maybe something like (ng-use is an hypothetically directive):
<ul>
<li ng-repeat="item in items">
<img ng-use="item.type == 'user'" ng-src="item.src">
<a ng-use="item.type == 'vehicle'">{{item.link}}</a>
<span ng-use="item.type == 'animal'">{{item.name}}</span>
</li>
</ul>
<ul>
<li ng-repeat="item in items" ng-switch="item.type">
<img ng-switch-when="user" ng-src="item.src">
<a ng-switch-when="vehicle">{{item.link}}</a>
<span ng-switch-when="animal">{{item.name}}</span>
</li>
</ul>
API reference:
http://docs.angularjs.org/api/ng.directive:ngSwitch
Although this doesn't use ng-switch, it does get round the problem of not having a type field, which #DotNetHaggis pointed out.
<div ng-repeat="field in fields">
<div ng-if="field.user !== undefined">user info</div>
<div ng-if="field.vehicle !== undefined">vehicle info</div>
<div ng-if="field.animal !== undefined">animal info</div>
</div>
