Controlling contents of a <div> in angular js - angularjs

I have a single page with the following html:
<div ng-controller="TraceController">
<div ng-repeat="trace in traces">
<div>{{ trace }}</div>
</div>
</div>
<div ng-controller="DetailedTraceController">
// I want this content to be defined by the clicking of the above.
</div>
I have already populated traces with an array of data. What I would like to do now is to make another $http call based on the clicking of the individual trace elements.
The question is which is the most correct element to use for my trace element? <a> or just a <div>?
Also, what would be the most angular way to then trigger a call to the DetailedTraceController to then call another $http method with the trace details from above?

The way I ended up solving this was with the following:
<div ng-controller="TraceController">
<div ng-repeat="trace in traces">
<div ng-click="clickTrace(trace)">{{ trace }}</div>
</div>
</div>
Which then set up a method call to clickTrace with the trace in question.

toggle extra detail for a record inside an ngRepeat

I'm working on a project where the client has supplied a pile of html where I need to plugin the data from our database and have hit a problem that I'm finding difficult to solve....
So first problem is with routing
<div ng-repeat="class in vm.classes">
<div class="class-overview">
<a href="#">
<span class="class-title">{{class.description}}</span>
... more stuff here
</a>
</div>
<div class="class-information collapse">
<div class="full-width">
{{class.longDescription}}
</div>
</div>
</div>
he has supplied some javascript to handle the click on class-overview
$('.class-overview a').on('click',function(e) {
e.preventDefault();
});
$('.class-overview').on('click',function() {
$('.class-overview.active').removeClass('active').next('.class-information').collapse('hide');
$(this).addClass('active').next('.class-information').collapse('show');//.css('top',offset).collapse('show');
});
and i have a line like this in my state provider
// default route
$urlrouterProvider.otherwise("/")
So the problem is that the ui-router handles the click and sends me back to the home page.
The ideal solution is to leave as much of his markup intact, so can anyone tell me how I stop ui-router handling the click?
or failing that, how I might use ng-click and ng-show to get the same effect, i.e. hiding and showing the class-information div...
If I understand well your question, you want to display the .class-information div when you click on the .class-overview element.
That can be done by using a variable in a ng-show like this:
<div ng-repeat="class in vm.classes">
<div class="class-overview">
<a href="#" ng-click="display = !display">
<span class="class-title">{{class.description}}</span>
... more stuff here
</a>
</div>
<div class="class-information" ng-show="display">
<div class="full-width">
{{class.longDescription}}
</div>
</div>
</div>
The display variable will be falsy when you land on the page, therefore the ng-click will be executed, this variable will be set to true.
I see that you are using a collapse class to hide the content if it is collapsed. Then you could use angular ng-class to put the collapse class when the display variable is false. Your div.class-information would look like this:
<div class="class-information" ng-class="{collapse: !display}">
<div class="full-width">
{{class.longDescription}}
</div>
</div>

How to: Angular Tree?

Hi all you experts out there.
My testing area: http://plnkr.co/edit/ddJT1e4a8L5NTSIVNTk7
I am trying to visualize hierarchical data in a tree-form with Angular, even though i'm using some samples to aid me in my quest (like http://jsfiddle.net/alalonde/NZum5/ and http://jsfiddle.net/brendanowen/uXbn6/8/) i fail.
As soon as i place the recursive element ng-include inside the ng-repeat in side the template it self, the memory usage of its browser-window goes through the roof and effectively hangs the browser. But the available tree-sample i could find are doing just that.
What am i missing?
You need to use the same variable name in the template. The current node is called node in the controller then child in the template.
This cause the template to render the same node over again.
It works fine if you use the same variable name :
<li ng-repeat="node in node.children" ng-include="'node.html'"></li>
See it in action here : http://plnkr.co/edit/mjfdSEDcMK8kGCRjS6V6?p=preview
If anyone here wants to avoid having the extra ng-repeat outside of the template (where it kind of includes stuff from the template anyway), here's a fiddle showing how to do it:
http://jsbin.com/hokupe/1/edit
Also here's a blog post and a 10-15 minutes video on how it works:
http://gurustop.net/blog/2014/07/15/angularjs-using-templates-ng-include-create-infinite-tree/
Sample Code:
<script type="text/ng-template" id="treeLevel.html">
<ul>
<li ng-repeat="item in items">
<input type="checkbox"
name="itemSelection"
ng-model="item._Selected" />
{{item.text}}
<div ng-include=" 'treeLevel.html'"
onload="items = item.children">
</div>
</li>
</ul>
</script>
<div ng-include=" 'treeLevel.html' "
onload="items = sourceItems">
</div>

repeat inside dynamic popover - angularjs and ui-bootstrap

I'm trying to show the user a list of items inside of a popover that is all inside an ng-repeat. I'm using angularjs as well as the ui-bootstrap package (http://angular-ui.github.io/bootstrap/).
HTML
<div ng-repeat='session in sessions'>
<p popover="{{session.items}}">view items</p>
</div>
This will show the array session.items for each session, which contains the information I want to show. However, this shows the brackets of the array as well.
Does anyone know a clean way to do this?
any help would be appreciated, thanks in advance
From ui-bootstrap site you can read
uib-popover - Takes text only and will escape any HTML provided for the popover body.
So if you provide session.items you will get string '[my array content]'. In my opinion you need to use uib-popover-template where your template would be like
<div ng-repeat='session in sessions'>
<p uib-popover-template="'urlToMyTemplateHere'">view items</p>
</div>
------ Template
<div ng-repeat="item in session.items" ng-bind="item"></div>
uib-popover-template takes an url to the template so you have to create file for it to be fetched or try this approach ( I don't really like it but just for testing )
<div ng-repeat='session in sessions'>
<p uib-popover-template="'iamabadapproachtemplate.html'">view items</p>
</div>
<script type="text/ng-template" id="iamabadapproachtemplate.html">
<div ng-repeat="item in session.items" ng-bind="item"></div>
</script>

AngularJS: 1.2.0rc2 ng-switch does not remove previous content

updated: made a smaller poc, in plunkr to show the problem without the entire application around it.
see it here
issue: data-ng-switch works on inline content, but does not remove the previous element when switching using external templates via data-ng-include.
works
<div data-ng-switch="view">
<div data-ng-switch-when="template1">content 1</div>
<div data-ng-switch-when="template2">content 2</div>
</div>
doesn't work
<div data-ng-switch="view">
<div data-ng-switch-when="template1" data-ng-include="'template1.html'"></div>
<div data-ng-switch-when="template2" data-ng-include="'template2.html'"></div>
</div>
Best solution I currently found can be seen in the plunkr
you basically cannot use ng-include on the same dom level as the ng-switch anymore. The same goes for other logical directives like ng-show ng-hide...
adding the ng-include on a child node of the ng-switch-when element works:
<div data-ng-switch="view">
<div data-ng-switch-when="template1">
<div data-ng-include="'template1.html'"></div>
</div>
<div data-ng-switch-when="template2">
<div data-ng-include="'template2.html'"></div>
</div>
</div>
update
Should be fixed in .rc3!
This was confirmed as a bug in the angular rc2 version (confirmation in this google group discussion).
The actual bugticket can be found here.

angularjs - toggle ng-class from multiple ng-clicks

I've just started working on a project that requires me to learn AngularJS. What I'm trying to do is create two menus that slide into the screen, one from the left, one from the right. When they do this they push the content over.
Currently I can get one or the other to work, but not both. I realize this is because of the way that I'm defining the ng-class. I just can't quite conceptualize how to do it correctly.
<div ng-class="{true:'slide-left', false:''}[toggleSlide]" class="container">
<div class="content">
<button ng-click="toggleSlide = !toggleSlide" class="btn-left">From Left</button>
<button ng-click="toggleSlide = !toggleSlide" class="btn-right">From Right</button>
</div>
<div class="slide-from-left">
<p>Here is information that slides from off screen left.</p>
</div>
<div class="slide-from-right">
<p>Here is information that slides from off screen right.</p>
</div>
</div>
Set up the ng-class syntax like this for what you want:
<div ng-class="{'slide-left':toggleSlide, 'slide-right':!toggleSlide}" class="container">
Also, I'm guessing you were trying to adapt your code to something else you saw, so I'll offer something on that also. Here's an ng-class using ng-repeat's $index to dole out classes for even and odd:
ng-class="['even', 'odd'][$index % 2]"
