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.

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 {{$index}} and you should always use .length to check if it has more than 1 value. This way you can achieve what you want and you should also learn something about arrays in javascript and what is the differnece between dot and bracket. Please read this http://www.dev-archive.net/articles/js-dot-notation/. I think you should learn the basics of javascript.
How do I get the id of a parent element of currently clicked element in AngularJS?
<div id="d8" class="menutitles ng-scope" ng-repeat="title in list">
<div class="right" ng-click="showsubmenu($event)">+</div>
<div class="left" ng-click="showsubmenu($event)">Unit 9</div>
</div>
How to get the value d8 in showsubmenu($event) function?
Below is what I tried but it doesn't work
$scope.showsubmenu=function(obj)
{
alert(obj.target.parent.attributes.id)
}
It should be parentNode, not just parent:
alert(obj.target.parentNode.id);
Also attributes is redundant as you can access id property directly.
But note, that since you have ngRepeat, it will create invalid markup, since ids are going to be duplicated. You probably want to fix this too, maybe like this or use classes:
<div id="d8{{$index}}" class="menutitles ng-scope" ng-repeat="title in list">
<div class="right" ng-click="showsubmenu()">+</div>
<div class="left" ng-click="showsubmenu()">Unit 9</div>
</div>
<div id="d8" class="menutitles ng-scope" ng-repeat="title in list">
<div class="right" ng-click="showsubmenu()">+</div>
<div class="left" ng-click="showsubmenu()">Unit 9</div>
</div>
It should be enough :D
function showsubmenu($event){
$($event.target).parent();
}
Have a nice day
As an addition to Pedro's answer I'd say that using the jQuery method closest would be preferable.
function showsubmenu($event){
var parent = $($event.target).closest('.yourclass'); // or any selector you prefer
}
I have two nested ng-repeat to list dishes of different categories, and I'm using UI Sortable to be able to sort those lists. The ng-model name for the latter is dynamic (matches the value of the category listed) and I simply don't know how to set that name and make it work.
I used $eval() to set that dynamic name in the ng-repeat and works fine, but tried the same for the model and it doesn't work. Any ideas? Thank you!
"categories" object:
All categories have items, for example first one "breakfast" (matching the "value" of the category) will look like this:
What I've tried:
<div ng-repeat="cat in categories">
<div class="row">
<div class="category-title">{{cat.name}}</div>
</div>
<div ui-sortable ng-model="cat.value">
<!-- <div ui-sortable ng-model="$eval(cat.value)"> -->
<div class="row" ng-repeat="(key,dish) in $eval(cat.value)">
<div class="dish-title">{{dish.name}}</div>
</div>
</div>
</div>
The following should work:
<div ui-sortable ng-model="this[cat.value]">
<div class="row" ng-repeat="(key,dish) in this[cat.value]">
<div class="dish-title">{{dish.name}}</div>
</div>
</div>
I would like to use ng-switch because I do not want the other elements that I do not want to show to be part of the DOM. That is why i did not use ng-hide/ng-show. In the example below, I would like to only have the span tag be in the DOM without the div wrappers from the ng-switch. What is the best way to accomplish this?
<div ng-switch on="user">
<div ng-switch-when="true">
<span>One</span>
</div>
<div ng-switch-when="false">
<span>Two</span>
</div>
</div>
You can use the ng-switch directive as a custom element and not specify the div in the first place. For example:
<ng-switch on="user">
<span ng-switch-when="true">One</span>
<span ng-switch-default>Two</span>
</ng-switch>
Here is a plunker to play around with: http://plnkr.co/edit/zni6raUWOguhQh9jDiY3
the solution provided by #ChrisAuer this still creates a wrapping element.
AFAIK you'd have to use a custome directive. You may want to use angular-ui if
<div ui-if="user">
<span>One</span>
</div>
<div ui-if="!user">
<span>Two</span>
</div>
Probably, in your case, you'd be fine using ng-show or ng-hide which only hide(display:none) the element - they don't remove it form the DOM.
<div ng-show="user"> <!-- same as ng-hide="!user" -->
<span>One</span>
</div>
<div ng-hide="user"> <!-- same as ng-show="!user" -->
<span>Two</span>
</div>
I would say use ng-if, like this:
<div>
<div ng-if="user==true">
<span>One</span>
</div>
<div ng-if="user==false">
<span>Two</span>
</div>
</div>
you can use <span> to prevent your html layout changing
because <span> is not like <div>, it won't take up any space.
<span ng-switch="user">
<span ng-switch-when="true">One</span>
<span ng-switch-default>Two</span>
</span>
My index.html page is like as follows:
<div id="sidepanel" data-ng-controller="ListCtrl">
<li data-ng-repeat="record in records">
{{record.id}}
<input type="checkbox" data-ng-model="addwidget">
</li>
</div>
<div id="main">
<div data-ng-view></div>
</div>
for this data-ng-view i have another page recordlist.html in that i have following code:
<div data-ng-controller="ListCtrl">
<ul class="design">
<li data-ng-repeat="record in records">
<div data-ng-switch data-on="record.category">
<div data-ng-switch-when="reporting1">
<div id="{{record.id}}" data-ng-show="addwidget">{{record.description}}</div>
</div>
<div data-ng-switch-when="reporting2">
<div id="{{record.id}}" data-ng-hide="addwidget">{{record.description}}</div>
</div>
</li>
</ul>
</div>
My question is i want to show the first div when i check the checkbox & when i uncheck it i want to show the second div.When both of the data-ng-model & data-ng-hide/show are on the same page then it works fine but in my case it present on two different pages.
Is it correct ? How can i implement this. Need Help.Thanks.
The problem is that you are setting addwidget in the first controller, but is trying to use it in the second. Controllers are not singletons.
So, in this situation:
<div id="sidepanel" data-ng-controller="ListCtrl">
...
</div>
<div id="main">
<div data-ng-view>
<div data-ng-controller="ListCtrl">
</div>
</div>
</div>
You got two separated controllers and scopes. And you are setting addwidget in the first trying to read in the second.
You can either bind it to the root scope $root.addwidget or use a service share to the states.
As you have many records, binding directly to root is a problem, as all of them are going to share the same state. So you gonna need an object in the rootScope and bind the option by id $root.addwidget[record.id]. Made a pretty simplified modification here.
