twitter bootstrap - Angular-ui tooltip with HTML

Question

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?

Answer 1

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() }">
" +
    "  <div class="tooltip-arrow"></div>
" +
    "  <div class="tooltip-inner" ng-bind-html-unsafe="getToolTipHtml()"></div>
" +
    "</div>
" +
    "");
}]);

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',

                }
            };

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>
