Hey all I'm trying to get a feel for angular and have ran into a little snag.
I have a container structure like the following:
<div class="main-container" ng-view>
<!-- The below divs are constantly being
reloaded based on the current URL and it's associated view -->
<div class="left-col">
</div>
<div class="right-col">
</div>
</div>
Before I implemented Angular I just had a simple script that would check the height of the window and set the height of the left column and right column divs accordingly.
With angular there is probably a better way to do this then attaching an event function to the window object. Basically I want to fire a function everytime a new view is rendered but not duplicate the below code in all of my angular controllers like so:
$scope.$on('$viewContentLoaded', setColumnHeight);
Any help would be appreciated. Thanks!
I've solved this problem in my app by having a root "Application Controller" at the top of the DOM tree. For example:
<body ng-controller='applicationController'>
...
<div class="ng-view"></div>
...
</body>
applicationController is always there, and can set up bindings on its scope when it is created.
You could use something like this:
<div class="main-container" ng-view>
{{ setColumnHeight() }}
<!-- The below divs are constantly being
reloaded based on the current URL and it's associated view -->
<div class="left-col">
</div>
<div class="right-col">
</div>
</div>
and it will check the height every time a render is made, however, this seems to be a bit over processing.
The best approach would be to only update the height from both columns when the height of one of them changes. For that you could use DOM Mutation Observers, however they are not yet available on all browsers. If that's not a problem for you, check the mutation-summary lib.
If you are using jQuery you can also try this: https://github.com/jqui-dot-net/jQuery-mutate (examples here).
How about putting that event listener on the root scope:
$rootScope.$on('$viewContentLoaded', setColumnHeight);
