Working with attributes in AngularJS directives

Building an overlay (or modal window) in AngularJS has been on my mind, and I've made some progress with the html/css layout. Here's a sneak peek at what it looks like:

<section class="calendar">
    <a open-overlay="overlay-new-calendar">Add New Calendar</a>
</section>

<section class="overlay overlay-new-calendar">
    <span class="bg"></span>
    <form class="wrap">
        <header>
            Add a New My Calendar
        </header>

        <div class="main">
            <label>Name<input type="text" required ng-model="newCalendar.calendar_name" /></label>
            <label>Color<input type="text" required ng-model="newCalendar.calendar_color" /></label>
        </div>

        <footer>
            <button type="submit">Add</button>
            <a close-overlay="overlay-new-calendar">Cancel</a>
        </footer>
    </form>
</section>

In the setup above, you will notice that I have used an anchor

<a open-overlay="overlay-new-calendar">Add New Calendar</a>
, where I attach an open-overlay directive aimed at making it universally applicable by specifying which exact overlay to trigger. However, I encountered some challenges while attempting this.

fixEvents.directive('openOverlay', function() {
    return function(scope, elem, attr) {
        elem.bind('click', function() {
            alert(attr.open-overlay);
            $('.overlay-new-calendar').show();
        });
    }
});

I am struggling to retrieve the attribute to display overlay-new-calendar. Furthermore, I would appreciate any suggestions on implementing show/hide functionalities without relying on jQuery. Your insights are greatly appreciated! - Daniel

Answer №1

peterorum is absolutely right.

To expand on his response, make sure to follow these steps:

  1. Be sure that you have scope.newCalendar defined in your code. Also define scope.isNewCalendarOverlayVisible = false in the same location.
  2. Include ng-click="isNewCalendarOverlayVisible=true" as an attribute on the link or button intended to open the overlay.
  3. Insert ng-show="isNewCalendarOverlayVisible" into your overlay element.

This setup allows your overlay to monitor the scope property and determine its visibility. Clicking the button will change this property to true, making the modal visible.

Answer №2

To display or conceal elements without relying on jQuery, utilize an attribute like "ng-show=myValue". This means that your directive would need to modify the value of a model, such as setting scope.myValue = true;

When accessing your attribute, be sure to reference it as attr.openOverlay, since attribute names are standardized within the directive.

Answer №3

attr function helps to standardize the attributes on your HTML element. The attribute open-overlay is treated in the same way as data-open-overlay, and can be accessed through attr.openOverlay.

If you need more information, check out: http://docs.angularjs.org/api/ng.$compile.directive.Attributes

For showing and hiding elements, consider using peterorum's solution with ng-show.
