How can I do something like this?
<scrollable-directive>
<fun-content-directive>
</fun-content-directive>
</scrollable-directive>
e.g I want to build out a custom scrolling container with events for infinite scrolling, etc. that I can put content in.

What is the best way to trigger/activate CSS animation from within a function in AngularJS?
In my case, I have a slide, which has one label <> and a button <>.
When a user clicks on the button, I'm calling an API, and on failure case, I need to animate the label.
One way will be to use ng-class directive. In which creating a scope variable, and set and reset value using $timeout service.
But I'm thinking of making a function something like playAnimation() and call this function which will trigger the animation.
What will be the steps for doing so in anularjs?
I'm using angularjs version 1.5.
I don't think creating a function would be better than using ng-class as you initially suggested. You could them benefit from Angular's animation classes (e.g. ng-enter, ng-leave etc), saving code in your scripts.
I am using UI Bootstrap's typeahead directive, and added my own popup template via typeahead-popup-template-url. In that template, I'd like to access scope variables from the parent template (i.e. the one in which I've used the typeahead directive). Is this possible?
Here's a (broken) example of what I'm trying to do ("hello" should be present in the dropdown): http://plnkr.co/edit/ITT1SdRfUWeeN6n3aMqu?p=preview
I'd like to do this WITHOUT modifying the typeahead directive. I don't want to muck around in third party (uib) code if there's a more elegant solution.
In your template, you need to reference the $parent scope. Change:
This should say "hello": {{hello}}</h1>
To:
This should say "hello": {{$parent.hello}}</h1>
Bootstrap, jquery ui, kendoui, yui etc
Isn't that a bit much of frameworks together O.o
Anyway this post might help: How to access parent scope from within a custom directive *with own scope* in AngularJS?
I'm currently working on a new custom directive which will transclude some HTML around the element you've called it on. This means however that if you have a ng-show directive as well on the element that the HTML would still be transcluded and hence shown.
A working example of the directive is located on this Plunk.
I'd like to counter this, by making my custom directive respond to ng-show but I can see a big problem with this approach as ng-show will hide or show the whole element it is called on.
On the other hand, I don't really like having a lot of custom directives each defining their own visible properties as an alternative to ng-show.
A third option would be to support both? This would allow me to switch of specific directives on an element as well as hiding it completely with ng-show
Has anyone got good recommendations on which approach I would have to take here? This is not a solitary case, we have a lot of custom directives of which we'll need to control visibility.
To summarize, these are the three options I'm thinking of:
Let custom directive respond to ng-show
Define own visibility control per custom directive (which could use ng-show underlying)
Support option 1 and 3
Any insights greatly appreciated.
My site's theme uses custom checkboxes and other items that I need to style. It uses $(".styled, input:radio, input:checkbox, .dataTables_length select").uniform(); to do so.
I'm wondering if instead of creating a bunch of directives if I can just tap into the template rendering and execute this method on the template node.
Why not just a uniform directive, which then you apply to whatever needed? There are surely things (like the .styled ones) which do not come from a template directly.
I have an application that contains a div with content in it. When I click a button jQuery adds a AngularJs directive to the div. After adding the directive i call scope.$apply(), but this doesn't seem to inform angular about the new directive on the div. Can someone explain to me how I can inform AngularJs about the new directive added with jQuery?
You shouldn't be adding directives to your markup with JQuery. Use Angular for that whenever possible.
That said, if you have to add directives via straight DOM manipulations like that, you'll need to use the $compile provider to compile the element and bind it to a scope before you add it.
