I have two directives that should both use isolate scopes, <outer-box> and <flag>. When I click on the <flag> directive, I want to change the background color of the other directive. Before importing my code into JSFiddle, I also had it working so that by default, a placeholder image appears in the flag directive, but once you click on that image, the country flag appears instead.
Can someone help with the styling a separate directive on ng-click?
Here's my code: https://jsfiddle.net/nLduw6xw/
(My countries data isn't working in JSFiddle for some reason)
You can do it with requiring one directive from another.
In this example you can require outer-box to be a parent of flag.
With this you have the access to required directive controller ( 4th parameter in link function), so you can call a method to set class on element.

I needed an circle progress indicator within cells of a table, which is rendered through an ng-repeat. So, I used an angular plugin, Which is an basically angular directive. When i use this directive within an ng-repeated div, those directive aren't compiling correctly. And, the directive is working correct, if there is no ng-repeat.

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?
The situation is I have an HTML structure somewhat similar to this:
<div class="dynamicDirectiveGoesHere">
<p>{{SomeExpressionThatDiffers}}</p>
</div>
I need to display a bootstrap http://angular-ui.github.io/bootstrap/ popover when the text within p has an ellipsis. That's why I'm adding the popover attribute dynamically. I can get the popover to display using $compile, but the problem is the text within {{ }} goes away. I can't use the template trick since I don't really know what the template will be since the popover will happen on several different child tags that have different templates. So that's why there is the need to only $compile what's in div, and not in the child element (p tag). Is this possible with angular?
You can add the property terminal to your directive and adjust the priority to fit your needs.
terminal: true prevents other directives from getting instantiated and is used by for example the ng-repeat and ng-if directive.
You can read more here https://docs.angularjs.org/api/ng/service/$compile (scroll down to terminal).
I am trying to build out a multistep form for a complex object. I use the modal to section out parts of the form. The Ionic examples I could find, appear to assign a different controller to the modal. I would like to keep the view plus all the modals it launches, all of them associated with one controller. Is that possible? I tried assigning to the modal view ng-controller="viewCtrl" where viewCtrl is also the controller of the starting view that launches the modal, but it appears to hang chrome with a high CPU which subsequently necessitates killing the chrome tab.(some sort of cyclic effect by calling the same controller??)
Your advice/insight would be welcome.
I assume that your modal is a directive.
I also assume that you have it placed inside the view (controller scope).
If the above are correct than the directive inherits the $scope properties and methods from the parent controller (a general thing in angular), unless your directive has an isolated scope (if you have the scope property in the directive set to anything but false).
If your directive has an isolated scope you can still pass data from the parent using attributes on the directive. If you want to pass something from the directive to the parent you can use $emit.
You can also access the parent from the directive using $parent but I would suggest against it.
Folks,
I am wondering if there is better way to include the $dialog module in angular code.
Please look at this plunkr : http://plnkr.co/edit/yXf1kNMqhAdo3iM8dFBy
All it does is open a modal upon clicking a button.
But setting up this modal is messy as I have to put the code in the main controller (which is TestCtrl incase of my plunkr)
Does anyone know how to make this into a directive so that I can simply have it in my template like
Click here to open modal
Thanks,
I can't see your code, but if you create a directive, you can move the controller code to the directive link function and output the DOM elements through the template property of the directive.
Even if you don't want to mess with the template replacement, you can at least move the code from the controller into the directive and just have the modal html as a hidden area in the main view. I have done that whenever I have used modal.
Here is a plunkr I did that illustrates pulling the controller code into a directive: http://plnkr.co/edit/3esMvm?p=preview
