What’s the best way to cancel event propagation between nested ng-click calls?

by

Here’s an example. Let’s say I want to have an image overlay like a lot of sites. So when you click a thumbnail, a black overlay appears over your whole window, and a larger version of the image is centered in it. Clicking the black overlay dismisses it; clicking the image will call a function that shows the next image.

The html:

<div ng-controller="OverlayCtrl" class="overlay" ng-click="hideOverlay()">
    <img src="http://some_src" ng-click="nextImage()"/>
</div>

The javascript:

function OverlayCtrl($scope) {
    $scope.hideOverlay = function() {
        // Some code to hdie the overlay
    }
    $scope.nextImage = function() {
        // Some code to find and display the next image
    }
}

The problem is that with this setup, if you click the image, both nextImage() and hideOverlay() are called. But what I want is for only nextImage() to be called.

I know you can capture and cancel the event in the nextImage() function like this:

if (window.event) {
    window.event.stopPropagation();
}

…But I want to know if there’s a better AngularJS way of doing it that won’t require me to prefix all of the functions on elements inside the overlay with this snippet.
