I am currently adding some bootstrap tooltips in my application.

All of the "normal" tooltips are ok, but when I want to use tooltip-html-unsafe, all I got is an empty tooltip.

My tooltip:

<a><span tooltip-placement="right" tooltip-html-safe="{{myHTMLText}}"> Help </span></a>

In the DOM, I have:

<div class="tooltip-inner" ng-bind-html-unsafe="content"></div>

The div's content seems empty, so there is nothing to show in the tooltip. I tried to put directly in the DOM some HTML text like:

<div class="tooltip-inner" ng-bind-html-unsafe="content"><b>test</b></div> and it works.

Do you have an idea?

The html-unsafe directive is designed to point at it's content. What about this:

<div data-ng-controller="SomeCtrl">
    <span data-tooltip-html-unsafe="{{yourContent}}" data-tooltip-placement="right">
        Help
    </span>
</div>

Then, in SomeCtrl, make a variable to hold the html:

$scope.yourContent = "<b>my html, yay</b>

IF you would like to modify bootstrap to take the content from a element, it can be done like this. First, you must change the tooltip template so that it calls a function to get the html:

angular.module("template/tooltip/tooltip-html-unsafe-popup.html", []).run(["$templateCache", function($templateCache) {
  $templateCache.put("template/tooltip/tooltip-html-unsafe-popup.html",
    "<div class=\"tooltip {{placement}}\" ng-class=\"{ in: isOpen(), fade: animation() }\">\n" +
    "  <div class=\"tooltip-arrow\"></div>\n" +
    "  <div class=\"tooltip-inner\" ng-bind-html-unsafe=\"getToolTipHtml()\"></div>\n" +
    "</div>\n" +
    "");
}]);

Then, make a link function for the tooltipHtmlUnsafePopup:

.directive( 'tooltipHtmlUnsafePopup', function () {
  return {
    restrict: 'E',
    replace: true,
    scope: { content: '@', placement: '@', animation: '&', isOpen: '&' },
    templateUrl: 'template/tooltip/tooltip-html-unsafe-popup.html',
    link: function(scope, element, attrs) {
        scope.getTooltipHtml = function() {
            var elemId = '#' + scope.content;
            var htmlContent = $rootElement.find(elemId).html();
            return htmlContent;
        };
    }
  };
})

EDIT: Later I extracted the customized code from ui-bootstrap, which is good since you do not have to modify ui-bootstrap to use it now. Here is the extracted code, in a module called "bootstrapx". This is just for popovers (as I was not really using tooltips) but I feel like this should be easily adaptable for tooltips too.

angular.module("bootstrapx", ["bootstrapx.tpls","bootstrapx.popover","bootstrapx.popover.dismisser"]);
angular.module("bootstrapx.tpls", ["template/popover/popover-html.html","template/popover/popover-html-unsafe.html","template/popover/popover-template.html"]);


angular.module( 'bootstrapx.popover', [ 'ui.bootstrap.tooltip' ] )
    .directive('popover', [ function() {
        return {
            restrict: 'EA',
            priority: -1000,
            link: function(scope, element) {
                element.addClass('popover-link');
            }
        };
    }])
    .directive('popoverHtml', [ function() {
        return {
            restrict: 'EA',
            priority: -1000,
            link: function(scope, element) {
                element.addClass('popover-link');
            }
        };
    }])
    .directive('popoverHtmlUnsafe', [ function() {
        return {
            restrict: 'EA',
            priority: -1000,
            link: function(scope, element) {
                element.addClass('popover-link');
            }
        };
    }])

            link: function(scope, element) {
                element.addClass('popover-link');
            }
        };
    }])

        }]);

I have the dismissPopovers directive on the body tag (this is likely applicable for tooltips too, you will just have to modify it to suit your needs):

<body data-ng-controller="AppController" data-dismiss-popovers>

According to angular-ui's wiki, this is the correct syntax. http://angular-ui.github.io/bootstrap/#/tooltip I tried yours, it didn't worked. –  Mencls Sep 26 '13 at 15:46
    
Oh crap! You are right, I forgot, I modified bootstrap to support that. Normally, it wants the actual content. –  aet Sep 26 '13 at 16:01
    
Thanks for your answer. Where do I have to put the link function ? –  Mencls Sep 26 '13 at 16:39

Ok I found a quicker way to fix it here. But yours was good too ;) –  Mencls Sep 27 '13 at 8:17

@simmi simmi I have edited the answer to include the popover dismisser that I use, hopefully that will help you! –  aet May 21 at 15:12

I have created custom directive which allows html tooltips for bootsrap in very simple way. No need to override any templates:

angular.module('vermouthApp.htmlTooltip', [
])
.directive('vaTooltip', ['$http', '$templateCache', '$compile', '$parse', '$timeout', function ($http, $templateCache, $compile, $parse, $timeout)
{
    //va-tooltip = path to template or pure tooltip string
    //tooltip-updater = scope item to watch for changes when template has to be reloaded [optional (only if template is dynamic)]
    //All other attributes can be added for standart boostrap tooltip behavior (ex. tooltip-placement)
    return {
        restrict: 'A',
        scope: true,
        compile: function (tElem, tAttrs)
        {
            //Add bootstrap directive
            if (!tElem.attr('tooltip-html-unsafe'))
            {
                tElem.attr('tooltip-html-unsafe', '{{tooltip}}');
            }
            return function (scope, element, attrs)
            {
                scope.tooltip = attrs.vaTooltip;
                var tplUrl = $parse(scope.tooltip)(scope);
                function loadTemplate()
                {
                    $http.get(tplUrl, { cache: $templateCache }).success(function (tplContent)
                    {
                        var container = $('<div/>');
                        container.html($compile(tplContent.trim())(scope));
                        $timeout(function ()
                        {
                            scope.tooltip = container.html();
                        });
                    });
                }
                //remove our direcive to avoid infinite loop
                element.removeAttr('va-tooltip');
                //compile element to attach tooltip binding
                $compile(element)(scope);

                if (angular.isDefined(attrs.tooltipUpdater))
                {
                    scope.$watch(attrs.tooltipUpdater, function ()
                    {
                        loadTemplate();
                    });
                } else
                {
                    loadTemplate();
                }
            };
        }
    };
}]);

Thats how you call it

 <a va-tooltip="'tooltipContent.html'" tooltip-updater="item" tooltip-placement="bottom">
                <b><i>{{item.properties.length - propertyShowLimit + ' properties more...'}}</i></b>
            </a>

And template can be like this:

<script id="tooltipContent.html" type="text/ng-template">
    <span ng-repeat="prop in item.properties>
        <b>{{prop.name}}</b>:
        <span ng-repeat="val in prop.values">{{val.value}}&nbsp;</span>
        <br />
    </span>
</script>
