I am trying to show the value from my json files using ng-repeat in angular js but I am unable to do that.
This is my code which I am trying:
<div ng-repeat = "x in myWelcome.definition">
{{x.attributes[0].children[0].node_id}}
<hr>
</div>
I have tried this and it is working:
<!-- first attributes start -->
<div ng-repeat = "x in myWelcome.definition.attributes">
{{x.rm_attribute_name}}<hr>
<div ng-repeat="a in x.children">
<div ng-if ="a.attributes">
a: {{a.attributes[0].rm_attribute_name}}
<div ng-if= "a.attributes[0].children">
chld
</div>
</div>
</div>
</div>
<!-- second attributes end -->
I am trying to understand how this line is working {{a.attributes[0].rm_attribute_name}} why it is not working like this {{a.attributes1.rm_attribute_name}} this is confusing. How it is shwoing all the results when I am using 0 and index.
And my json file is here in the plunker:
Plunker link of json and code
So how can I iterate here using ng-repeat here this code:
{{myWelcome.definition.attributes[0]}}
is working how can I show this in my view using ng-repeat I need to show all the attributes and child using ng-repeat.
ng-repeat can be used in the following way:
<div ng-repeat = "(key,value) in myWelcome.definition.attributes">
Key:{{key}} and value :{{value}}
<hr>
</div>
OR you can Try this:
<div ng-repeat = "x in myWelcome.definition.attributes">
<div ng-repeat="a in x.children">
a:{{a.node_id}}
</div>
</div>
Edited Plunker
I can see you are trying to implement ng-if and ng-repeat for your json file. You need to understand how ng-repeat works you can always check the index of you array using {{$index}}. So for your kind of problem I think this is the solution you should try.
<!-- first attributes start -->
<div ng-repeat = "x in myWelcome.definition.attributes">
{{x.rm_attribute_name}}<hr>
<div ng-repeat="a in x.children">
{{$index}}
<div ng-if ="a.attributes">
<div ng-repeat="b in a.attributes">
<hr>
{{b.children.length}}
<div ng-if="b.children.length > 1">
If the array is more than 1 please do the magic here
</div>
</div>
<div ng-if= "a.attributes[0].children">
chld
</div>
</div>
</div>
</div>
<!-- second attributes end -->
You can always see the indexes using {{$index}} and you should always use .length to check if it has more than 1 value. This way you can achieve what you want and you should also learn something about arrays in javascript and what is the differnece between dot and bracket. Please read this http://www.dev-archive.net/articles/js-dot-notation/. I think you should learn the basics of javascript.

How can I make bootstrap "jump" to the next row inside ng-repeat.
To clarify, I have something like this:
<div class=row>
<div class="col-sm-3" ng-repeat="field in fields">
</div>
</div>
What I want is to jump to the next row based on a condition inside ng-repeat. Like this:
[1][2][3]
[4][5]
[6][7][8]
The catch here is that I have to jump columns inside the column div.
Does anyone know the best way to solve this? Please tell me if my question isn't clear.
played a bit with ng-class hope that helps
its a bit confusing how bootstrap class works with angular
http://jsfiddle.net/8n9u54ud/
js:
angular.module('app',['QuickList']).controller('mainCtrl', function($scope){
$scope.myJson = [1,2,3,4,5,6,7,8,9]
})
html:
<div ng-app='app' ng-controller='mainCtrl'>
<div class="row">
<div ng-repeat="i in myJson" ng-class="{'col-sm-4':i!=5, 'col-sm-5':i==5}">
{{i}}
</div>
</div>
</div>
UPDATED
This can be a dumb question. But I hope you can help me with this. I'm doing something like this:
<div ng-repeat="item in list" class="display-item">
<ng-include src="mytemplate.html"></ng-include>
<div ng-if="($index%2) == 0">
<p>An inserted content when index is an even number.</p>
</div>
</div>
Now this is working. The problem starts when I'm making the page responsive in all devices, cause you see when I inserted the p tag, it was created inside the parent div tag with the class display-item. What I want to do is put it outside the div tag so when the screen is smaller the p tag will not be affected by the parent tag and vise versa. So something like this:
<div ng-repeat="item in list" class="display-item">
<ng-include src="mytemplate.html"></ng-include>
</div>
<div ng-if="($index%2) == 0">
<p>An inserted content when index is an even number.</p>
</div>
Now the problem with the code above is $index is undefined on that part of the code and I know ng-repeat will finish iterating first before going to the second div.
Thanks in advance!
This can be easily done by using ng-repeat-start and ng-repeat-end
Try like this:
<div ng-repeat-start="item in list" class="display-item">
<ng-include src="mytemplate.html"></ng-include>
</div>
<div ng-repeat-end ng-if="($index%2) == 0">
<p>An inserted content when index is an even number.</p>
</div>
#Jed, could you put a class tag on the ng-if div for an outer div? Say
<div ng-if="($index%2)" class="outer-div-you-want">
Just a thought to try.
I am using metro ui and am trying to use ng-repeat within it to build html within a popup.
My template looks like this. Any thoughts would help. I have verified the data is there, but ng-repeat just doesn't work within double quotes. I've tried using single quotes, but that doesn't work.
Here's my template.
<div class="container">
<div class="title-group six">
<a ng-repeat="product in products"
data-hint="{{product.name}}|<div><ul><li ng-repeat='color in product.colors'>{{color.name}}</li> </ul></div>" href="#/product/{{product.id}}" class="tile bg-violet" data-click="transform" >
<div class="tile-content icon">
<img src="{{product.pic}}">
</div>
<div class="brand">
<div class="label">{{product.name}} </div>
</div>
</a>
</div>
As a start, your HTML is malformed, you need a closing DIV tag on the end.
Also, in your ng-repeat, your variable name should be different to the array. I'd suggest something like:
ng-repeat="p in products" or ng-repeat="product in products"
Hopefully this helps.
I have the template:
<div ng-repeat="CableFilterName in CableFilterNames">
<fieldset>
<legend>{{CableFilterName.filterName}}</legend>
<ul id="">
<li ng-repeat="filterValue in CableFilterName.filterValues">
<input type="checkbox"/> {{filterValue}}
<!-- <select> -->
</li>
</ul>
</fieldset>
</div>
where filterValue in nested ng-repeat has several different values. So question is how to define what is current filterValue-value and depending on it use checkbox or select or any arbitrary HTML ?
UPD:
filterValues = ['Cable System','Electrical', 'Lighting'];
To have a kind of if statement, you can use the ngSwitch directive in AngularJS :
http://docs.angularjs.org/api/ng.directive:ngSwitch
For example on your ngRepeat loop :
<div ng-switch on="filterValue">
<div ng-switch-when="value1">//Do what you want when "value1"</div>
<div ng-switch-when="value2">//Do what you want when "value2"</div>
...
<div ng-switch-default>//Do what you want by default</div>
</div>
I Hope it's what you want, I don't really understand what you try to achieve.
The following code doesn't seem to work correctly:
<div ng-switch on="current">
<div ng-repeat="solution in solutions" ng-switch-when="{{solution.title}}">
{{solution.content}}
</div>
</div>
The output of {{solution.title}} is literally {{solution.title}}. It doesn't get processed by angular.
The ng-switch-when tag requires a constant, you can't put a variable in it.
You can rework your code as follows:
<div ng-repeat="solution in solutions">
<div ng-show="current == solution">
{{solution.content}}
</div>
</div>
