How do I create an AngularJS UI bootstrap popover with HTML content?

I want to create a bootstrap popover with a pre tag containing a prettified JSON object. The naive implementation,

<span popover='<pre>{[ some_obj | json:"  " ]}</pre>'
      popover-trigger='mouseenter'>

escapes the content before inserting it into the popup. What's the best way of specifying a popover body with html content?


Solution 1:

UPDATE:

As can been seen in this, you should now be able to do this without overriding the default template.

ORIGINAL:

As of angular 1.2+ ng-bind-html-unsafe has been removed. You should be using the $sce service Reference.

Here is a filter for creating trusted HTML.

MyApp.filter('unsafe', ['$sce', function ($sce) {
    return function (val) {
        return $sce.trustAsHtml(val);
    };
}]);

Here is the overwritten Angular Bootstrap 0.11.2 template making use of this filter

// update popover template for binding unsafe html
angular.module("template/popover/popover.html", []).run(["$templateCache", function ($templateCache) {
    $templateCache.put("template/popover/popover.html",
      "<div class=\"popover {{placement}}\" ng-class=\"{ in: isOpen(), fade: animation() }\">\n" +
      "  <div class=\"arrow\"></div>\n" +
      "\n" +
      "  <div class=\"popover-inner\">\n" +
      "      <h3 class=\"popover-title\" ng-bind-html=\"title | unsafe\" ng-show=\"title\"></h3>\n" +
      "      <div class=\"popover-content\"ng-bind-html=\"content | unsafe\"></div>\n" +
      "  </div>\n" +
      "</div>\n" +
      "");
}]);

EDIT: Here is a Plunker implementation.

EDIT 2: As this answer keeps getting hits, I'll keep it updated as best I can. As a reference Here is the template from the angular-ui bootstrap repo. If this changes, the override template will require matching updates and the addition of the ng-bind-html=\"title | unsafe\" and ng-bind-html=\"content | unsafe\" attributes to continue working.

For updated conversation check the issue here.

Solution 2:

Use the popover-template directive

If you are using a version of angular-ui equal or above 0.13.0, your best option is to use the popover-template directive. Here is how to use it:

<button popover-template="'popover.html'">My HTML popover</button>

<script type="text/ng-template" id="popover.html">
    <div>
        Popover content
    </div>
</script>

NB: Do not forget the quotes around the template name in popover-template="'popover.html'".

See demo plunker


As a side note, it is possible to externalize the popover template in a dedicated html file, instead of declaring it in a <script type="text/ng-template> element as above.

See second demo plunker

Solution 3:

I have posted a solution on the github project: https://github.com/angular-ui/bootstrap/issues/520

I you want to add this functionality to your project, here is a patch.

Add those directives:

angular.module("XXX")
    .directive("popoverHtmlUnsafePopup", function () {
      return {
        restrict: "EA",
        replace: true,
        scope: { title: "@", content: "@", placement: "@", animation: "&", isOpen: "&" },
        templateUrl: "template/popover/popover-html-unsafe-popup.html"
      };
    })

    .directive("popoverHtmlUnsafe", [ "$tooltip", function ($tooltip) {
      return $tooltip("popoverHtmlUnsafe", "popover", "click");
    }]);

And add the template:

<div class="popover {{placement}}" ng-class="{ in: isOpen(), fade: animation() }">
  <div class="arrow"></div>

  <div class="popover-inner">
      <h3 class="popover-title" ng-bind="title" ng-show="title"></h3>
      <div class="popover-content" bind-html-unsafe="content"></div>
  </div>
</div>

Usage: <button popover-placement="top" popover-html-unsafe="On the <b>Top!</b>" class="btn btn-default">Top</button>

Solution 4:

You need to alter the default popover template to specify you want to allow Html content. Look the popover-content div, it now has its binding done to the content property allowing unsafe html:

 angular.module("template/popover/popover.html", []).run(["$templateCache", function ($templateCache) {
        $templateCache.put("template/popover/popover.html",
            "<div class='popover {{placement}}' ng-class='{ in: isOpen(), fade: animation() }'>" + 
            "<div class='arrow'></div><div class='popover-inner'>" + 
            "<h3 class='popover-title' ng-bind='title' ng-show='title'></h3>" + 
            "<div class='popover-content' ng-bind-html-unsafe='content'></div>" +
            "<button class='btn btn-cancel' ng-click='manualHide()'>Cancel</button>" +
            "<button class='btn btn-apply' ng-click='manualHide()'>Apply</button></div></div>");
    }]);

Solution 5:

For all your conventional Bootstrap popover needs you could utilize the following angular directive. It removes clutter from the HTML template and is very easy to use.

You can configure popover's title, content, placement, fade in/out delay, trigger event and whether content should be treated as html. It also prevents content overflow & clipping.
