I'm trying to do something very simple in Angular but can't seem to get it working. I want to use an ng-repeat and compare the $index with a number. somehow there is an error in my code, but i cannot find it. Any help will be uch appreciated. Cheers!
<li ng-repeat="(key, structure) in structures">
{{ $index }}
<div class="row" ngIf="{{$index}} == 1">
<div class="col8 itemBox"></div>
<div class="col4-odd-fix itemBox"></div>
</div>
<input style="display: inline-block" name="structure" type="radio" value="{{key}}" ng-model="$parent.structure" required>
{{key}}
</li>
This should work:
<li ng-repeat="(key, structure) in structures">
{{ $index }}
<div class="row" ng-if="$index === 1">
<div class="col8 itemBox"></div>
<div class="col4-odd-fix itemBox"></div>
</div>
<input style="display: inline-block" name="structure" type="radio" value="{{key}}" ng-model="$parent.structure" required> {{key}}
</li>
You had a couple of issues:
You need to use ng-if, ngIf is Angular 2 syntax.
You shouldn't use {{ }} inside ng-if, you just need $index === 1.

I'm trying to wrap an element in an ng-repeat loop if the item has specific values.
eg:
items={
{name:"AAA",cat:"1"},
{name:"BBB",cat:"2"},
{name:"CCC",cat:"1"},
{name:"DDD",cat:"3"}
}
...
<div ng-repeat="item in items">
{{item.name}}
</div>
will output:
<div>AAA</div>
<div>BBB</div>
<div>CCC</div>
<div>DDD</div>
Let's say I want to wrap items that have category=1.
required output:
<div class="wrapper">
<div>AAA</div>
</div>
<div>BBB</div>
<div class="wrapper">
<div>CCC</div>
</div>
<div>DDD</div>
Note that I already have a filter and an orderBy in my ng-repeat, so can't use that.
Any advice how to achieve that?
Many thanks
Edit: I can't use a class, I need a wrapper div.
It can be done just by using ng-class as follows-
function MainCtrl($scope) {
$scope.items=[
{name:"AAA",cat:"1"},
{name:"BBB",cat:"2"},
{name:"CCC",cat:"1"},
{name:"DDD",cat:"3"}
]
}
.wrapper {
background-color : #ccc;
width: 10%;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="" ng-controller="MainCtrl as main">
<ul>
<div ng-repeat="item in items">
<div class="wrapper" ng-if="item.cat == 1">
{{item.name}}
</div>
<div ng-if="item.cat != 1">
{{item.name}}
</div>
</ul>
</div>
EDITS:
According to your edited Question this is best of my knowledge. Its implemented in above snippet.
<div ng-repeat="item in items">
<div class="wrapper" ng-if="item.cat == 1">
{{item.name}}
</div>
<div ng-if="item.cat != 1">
{{item.name}}
</div>
Note: if you dont want to use Class it can be done using id
<div ng-repeat="item in items" ng-class="{'wrapper' : item.category == 1}">
{{item.name}}
</div>
You don't need an extra div
I have found this filter and I'm trying to edit it so that you select an option then it greys out the other option For example if you select (vegetable) you can only select (Orange).
I'm not sure how to out it into code but I the logic for it. On the dynamicFilter function need to update the filter options count and if its less then 1 needs to add a class or something.
Here is my code pen any help would be awesome.

<div ng-app='angularDemo' ng-cloak>
<md-toolbar layout-padding>
<h2>Filtering with Angular Filters</h2>
</md-toolbar>
<div layout="row" ng-controller="angularController as ctrl">
<div flex="20" class="sidebar" layout-padding>
<!-- Repeat the filter types and there options -->
<div ng-repeat="filter in Filters">
<h3>{{filter.name}}</h3>
<ul class="filteroptions">
<li ng-repeat="option in filter.options">
<input id="{{option.value}}" class="filter_option" type="checkbox" data-name="{{option.value}}" ng-model="option.IsIncluded" ng-checked="option.IsIncluded">
<label for="{{option.value}}">{{option.value}}</label>
</li>
</ul>
</div>
</div>
<div flex="50" layout="row">
<div flex ng-repeat="product in products | dynamicFilter:Filters:this" class="product">
{{product.name}}
</div>
</div>
</div>
</div>
You can add condition according to your filter like as ng-show="(products | unique:'price').length > 0"
Try this
<div class="side_menu">
<h2>Product Types</h2>
<div data-ng-repeat="product in products | unique:'type'">
<input id="{{product.type}}" type="checkbox" ng-model="search.type" ng-true-value="'{{product.type}}'" ng-false-value='' /><label for="{{ product.type }}">{{ product.type }} </label>
</div>
<br>
<h2 ng-show="(products | unique:'price').length > 0">Product Price</h2>
<div data-ng-repeat="product in products | unique:'price'">
<input id="{{product.price}}" type="checkbox" ng-model="search.type1" ng-true-value="'{{product.price}}'" ng-false-value='' /><label for="{{ product.price }}">{{ product.price }} </label>
</div>
</div>
I want to access the index of dashboardCtrl.labels in dashboardCtrl.labelColors which is another array.I have tried the following but no success. If I print just {{$index}} it is getting printed successfully}}
<div class="row" ng-repeat="i in dashboardCtrl.labels">
<div id="circle" style="background:green"></div>{{i}}
<label>{{dashboardCtrl.labelColors[{{$index}}]}}</label>
</div>
You don't need nested brackets {{ }}. Try this
<div class="row" ng-repeat="i in dashboardCtrl.labels">
<div id="circle" style="background:green"></div>{{i}}
<label>{{dashboardCtrl.labelColors[$index]}}</label>
</div>
Do the following. Just $index in {{dashboardCtrl.labelColors[$index]}} instead of {{dashboardCtrl.labelColors[{{$index}}]}}
<div class="row" ng-repeat="i in dashboardCtrl.labels">
<div id="circle" style="background:green"></div>{{i}}
<label>{{dashboardCtrl.labelColors[$index]}}</label>
</div>
EDIT
Apply CSS style attribute dynamically in Angular JS
ng-style="{'background-color': dashboardCtrl.labelColors[$index]}"
AngularJS
How can i get first element and add class 'active' automatically .
There is 2 ng-repeat , I want get first group --> first item --> first element and add class.
<div class="first" ng-repeat="group in group ">
<div class="second" ng-repeat="item in items">
<div ng-class="{'active': selectedGame.id === prematchGame.id}"></div>
</div>
</div>
You can do like this:
<div ng-class='{active:$first}' > {{item.data}}</div>
If you want to make active only the first element of the first ng-repeat, then try:
<div class="first" ng-repeat="group in groups">
<div class="second" ng-repeat="item in items">
<div ng-class='{active: $first && $parent.$first}'>{{item.data}}</div>
</div>
</div>
Demo on JSFiddle
simple way if all you want is first element
<div class="first" ng-repeat="group in group">
<div class="second" ng-repeat="item in items">
<div ng-class="{'active': $index == 1}" ></div>
</div>
</div>
you can do same for other ng-repeat all will have different $index
Use $first to do check for the first element of ng-repeat : Fiddle
<div class="first" ng-repeat="group in group" ng-init="firstGroup = $first">
<div class="second" ng-repeat="item in items">
<div ng-class="{'active': selectedGame.id === prematchGame.id}" ng-class='{active: $first && firstGroup}'></div>
</div>
</div>
How to increment init variable value in ng-repeat
<div ng-if="feedData.carouselMode == true" ng-init='start=0' ng-repeat="a in carousel_data">
<div class="owl-demo" class="owl-carousel" owl-carousel >
<div class="item" ng-repeat="(key, item) in a.carouselFeeds" ng-init="start=start+1">
{{start}}
<div ng-click="go('{{key}}', item.feedUrls.length, 'rtl')" ng-swipe-left="go('{{key}}', item.feedUrls.length, 'rtl')">
<img class="lazyOwl" ng-src="{{item.img}}" />
<span class="innersquare" image-ja="{{item.img}}">
<p ng-style="folderStyle">{{item.name }} </p> </span>
</div>
</div>
</div>
</div>
ng-init start=0 after increment start=start+1 in ng-repeat but no count only show 1.
This is because each ng-repeat has its own scope and each ng-init will just increase its own scoped variable. You can try access the parent scope with $parent.
In case you are looking for a continuous numeration try this
<div ng-controller="MyCtrl">
<div ng-repeat="a in ['a','b','c']" ng-init="current = $parent.start; $parent.start=$parent.start+3;">
<div ng-repeat="x in ['alpha','beta','gamma']">
{{current + $index}}
</div>
</div>
Where the +3 should be +[LENGTH OF INNER ARRAY].
http://jsfiddle.net/rvgvs2jt/2/
For your specific code it would look like this
<div ng-if="feedData.carouselMode == true" ng-init='current=$parent.start; $parent.start=$parent.start+a.carouselFeeds.length' ng-repeat="a in carousel_data">
<div class="owl-demo" class="owl-carousel" owl-carousel>
<div class="item" ng-repeat="(key, item) in a.carouselFeeds">
{{current + $index}}
<div ng-click="go('{{key}}', item.feedUrls.length, 'rtl')" ng-swipe-left="go('{{key}}', item.feedUrls.length, 'rtl')">
<img class="lazyOwl" ng-src="{{item.img}}" />
<span class="innersquare" image-ja="{{item.img}}">
<p ng-style="folderStyle">{{item.name }} </p> </span>
</div>
</div>
</div>
</div>
I guess you achieve this by simple {{$parent.$index}}
Update
As per comments
<div ng-controller="MyCtrl">
<div ng-repeat="a in one">
<div ng-repeat="x in two">
{{($parent.$index*two.length)+($index+1)}}
</div>
</div>
Controller:-
$scope.one= ['alpha','beta','gamma'] ;
$scope.two=['alpha','beta','gamma'];
Fiddle
You can be accessed with $index, check this code,
<div ng-app ng-controller="TestController">
<div ng-repeat="item in list">
<label>Input {{$index+1}}:</label>
<input ng-model="item.value" type="text"/>
</div>
{{list}}
</div>
and
function TestController($scope) {
$scope.list = [ { value: 'value 1' }, { value: 'value 2' }, { value: 'value 3' } ];
}
AngularJS is giving $index variable. We can use it.
<ul>
<li ng-repeat="item in items">{{ $index + 1 }}</li>
</ul>
