Typeahead in Angular is failing to function properly after using the $compile method

I have made some adjustments to the popover directive in order to include files and $compile them. While I've managed to make ng-repeats function properly, I'm facing issues when trying to add a typeahead feature.

angular.module("app").directive("boundPopover", ['$compile', '$http', function($compile, $http) {
  return {
    restrict: 'A',
    link: function(scope, element, attr, ctrl) {
      var content = attr["popoverContent"];
      var title = attr["popoverTitle"];

      function initPopup() {

        element.popover({
          html: true,
          content: $compile(content)(scope),
          title: $compile(title)(scope),
          placement: attr["popoverPlacement"]
        });
      };

      if(attr["popoverContentInclude"] || attr["popoverTitleInclude"]) {
        var contentLoaded = false;
        var titleLoaded = false;

        if(!attr["popoverContentInclude"]) {
          contentLoaded = true;
        }

        if(!attr["popoverTitleInclude"]) {
          titleLoaded = true;
        }

        if(!contentLoaded) {
          $http.get(attr["popoverContentInclude"]).success(function(d) {
            content = d;

            contentLoaded = true;
            if(titleLoaded) {
              initPopup();
            }
          });
        }

        if(!titleLoaded) {
          $http.get(attr["popoverTitleInclude"]).success(function(d) {
            title = d;

            titleLoaded = true;
            if(contentLoaded) {
              initPopup();
            }
          });
        }
      }
      else
      {
        initPopup();
      }
    }
  }
}]);

The included title file looks like this-

<span class="glyphicon glyphicon-search"></span><input class='devices-search' ng-controller="DeviceCtrl" typeahead="state for state in states | filter:$viewValue | limitTo:10" ng-model="state"/>

It functions correctly when placed directly on the page or within an ng-include, but it is not working in this specific situation. Any suggestions on what steps I can take?

Answer №1

After scouring through the typeahead directive sources, I stumbled upon a solution. All you need to do is enclose your input within a container like so:

var el = angular.element('<div><input type="text" typeahead="value in values" /></div>');
var compiled = $compile(angular.element('<div>').append(el).html())($scope)
myElement.append(compiled);

The Reason Behind It

Essentially, by creating your element as follows:

var el = angular.element('<input type="text" typeahead="value in values" />');

and then compiling and adding it to another element, you encounter an issue where the typeahead directive attempts to add a typeahead-popup like:

yourNewElement.after(popup)

Unfortunately, since yourNewElement lacks a parent, the popup ends up getting lost in the process.
