AngularJS Display Tooltip Content of Array of Strings / With HTML

Question

HTML (Jade):

a(href='#', data-placement='right', title="{{ someArrayOfStrings }}" tooltip)

where someArrayOfStrings is declared given a value during initialization in my angular controller:

Angular:

var myController = function($scope) {
    $scope.initialize = function(someArrayOfStrings) {
        $scope.someArrayOfStrings = someArrayOfStrings;
    }
};

var tooltip = function() {
    return {
        restrict: 'A',
        link: function(scope, element, attrs){
            $(element).hover(function(){
                $(element).tooltip('show');
            }, function(){
                $(element).tooltip('hide');
            });
        }
    };
};

Currently, this would give my tooltip content such as the following:

["string1","string2","string3"]

which is ugly as hell and totally NOT what I want.

What I want displayed is something like this:

string1
string2
string3

I have searched around and it seems like there are quite a few approaches to this but so far, I have not managed to get it to work nicely, e.g. http://jsfiddle.net/superscript18/fu7a2/6/, http://jsfiddle.net/WR76R/ and Render Html String in tooltip.

Alternatively, I could perhaps use a concatenated string delimited by <br/> tags. This would require that my tooltips accept HTML tags, however. There seems to be an tooltip option available, i.e. html: true, but I can't get it to work.

Ideas / Help?

Try this solution jsfiddle.

• First, create directive that create tooltip $(element).tooltip({html: 'true'}).

• Second, use stringArray.join('<br>') create string with br.

Example:

var myApp = angular.module('myApp', []);

myApp.controller('MyCtrl', function($scope) {
    $scope.name = 'Superhero';
    $scope.stringArray = ["string1", "string2", "string3"];

  })
  .directive('tooltip', function() {
    return {
      restrict: "A",
      link: function(scope, element) {
        $(element).tooltip({
          html: 'true'
        });
      }
    }
  });

<div ng-app="myApp">
  <div ng-controller="MyCtrl">
    Hello, {{name}}!
    <div ng-repeat="string in stringArray">
      {{ string }}
    </div>
    <a href="#" data-placement="right" title="{{ stringArray.join('<br>') }}" tooltip>tooltip</a>
  </div>
</div>

You just need to set the title property like title="{{ stringArray.join('\u000A') }}". Please check the fiddle http://jsfiddle.net/Noblemo/u9tt9xb2/
