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 have ng-repeat in my html. how I can add ng-repeat with dynamically changes name.
<div ng-repeat="category in categories"> //external repeat
<div ng-repeat="data in categoryData.{{categoryName here}}">
// want add instead .{{categoryName here}} defined (concrete) name from external loop.
In result I want have many places in html and different data for each place that will be places in categoryData.NameOfCategory .NameOfCategory will replaced to concrete name.
You can try this,
<div ng-repeat="category in categories">
<div ng-repeat="data in categoryData[category.name]">
<div ng-repeat="data in categoryData.['categoryName']">
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 {{$index}} and you should always use .length to check if it has more than 1 value. This way you can achieve what you want and you should also learn something about arrays in javascript and what is the differnece between dot and bracket. Please read this http://www.dev-archive.net/articles/js-dot-notation/. I think you should learn the basics of javascript.
I'm trying to filter an user list. I'm using a custom Bootstrap version and want to display a 4 columns table.
So far, I've the following code:
<div ng-repeat="user in users | filter:searchValue | orderBy: 'username'">
<span ng-switch on="$index % 4">
<span ng-switch-when="0">
<div class="row-fluid">
<div class="span3" ng-if="users[$index+0]">
<user-item ng-model="users[$index+0]" on-click="showUser(userId)"></user-item>
</div>
<div class="span3" ng-if="users[$index+1]">
<user-item ng-model="users[$index+1]" on-click="showUser(userId)"></user-item>
</div>
<div class="span3" ng-if="users[$index+2]">
<user-item ng-model="users[$index+2]" on-click="showUser(userId)"></user-item>
</div>
<div class="span3" ng-if="users[$index+3]">
<user-item ng-model="users[$index+3]" on-click="showUser(userId)"></user-item>
</div>
</div>
</span>
</span>
</div>
So far, it works perfectly when there is no filter set.
When I set a searchValue, the $index cannot display the correct value (It will always start from 0 to the lengh of the filtered array).
My question is: Is there a way to correctly display the results in a 4-cols table and to filter the result ?
I don't think you need to add conditions in order to create a 4 column table using bootstrap css, simply use ng-repeat in a col-* element or using your custom span class (which I assume is created using bootstrap's mixins to create rows and columns).
DEMO
HTML
<input ng-model="searchValue.username" />
<div class="row-fluid">
<!-- simply change col-xs-3 to span3 -->
<div class="col-xs-3" ng-repeat="user in users | filter:searchValue | orderBy: 'username'">
{{user.username}}
<user-item ng-model="user" on-click="showUser(user.id)"></user-item>
</div>
</div>
If the markup above does not work in your case because of the custom bootstrap that you're using, then you are probably better off with a filter that partitions your current array into sections of subarrays that represents a row-column relationship, answered by m59 in this SO Answer.
Next time try to give a shot to ngTasty table http://zizzamia.com/ng-tasty/directive/table it's based to bootstrap css table :)
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.
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.
