Embracing AngularStrap's Popover Feature

I am attempting to create a custom directive that wraps angular strap's popover functionality.

The goal is for the popover to be able to utilize a custom template provided by the user of my directive, and for the template to access the controller's scope.

To address the scope issue, I discovered that I can pass the controller's scope to the $popover service.

var myPopover = $popover(element, {
                title: 'My Title',
                placement : 'top',
                contentTemplate: 'example.html',
                html: true,
                trigger: 'manual',
                autoClose: true,
                scope: scope
            });

Here is an example on Plunker:http://plnkr.co/edit/9vTzR0fKcjOlP0bNjZUf?p=preview

Can someone clarify why both buttons are triggering the same popover? Should I isolate the scope? If so, how can I still access the original controller's scope to bind variables?

Thank you

Answer №1

I'm curious if someone can provide an explanation as to why both buttons are triggering the same popover?

The reason is that both `customPopover` directives are sharing the same scope. To resolve this, you need to configure the directive to create an isolated scope for each individual directive.

Simply add `scope: true` to your directive:

app.directive("customPopover", ["$popover", "$compile", function($popover, $compile) {
    return {
        scope: true,
        restrict: "A",
        link: function(scope, element, attrs) {
            var myPopover = $popover(element, {
                title: 'My Title',
                placement : 'top',
                contentTemplate: 'example.html',
                html: true,
                trigger: 'manual',
                autoClose: true,
                scope: scope
            });

            scope.showPopover = function() {
                myPopover.show();
            }
        }
    }
}]);

The issue here arises when customPopover is used multiple times, setting scope.showPopover each time. As both instances share the same scope, the first scope.showPopover gets overwritten when the directive is used a second time, pointing to the second element.

A simple solution is available - by accessing the element in the link function, a click handler can be added without worrying about scope collisions. This approach also enhances the self-contained nature of the directive. Check out this example which utilizes element.on instead of relying on scope and ngClick.
