AngularJS Question

Dynamic Content in Dynamic Tab (Angular, UI Bootstrap)

I'd like to use ng-include in the content of a dynamically generated tab using AngularJs and UI Bootstrap.

I have a Plunker here:
http://plnkr.co/edit/2mpbovsu2eDrUdu8t7SM?p=preview

<div id="mainCntr" style="padding: 20px;">
<uib-tabset>
<uib-tab ng-repeat="tab in tabs" active="tab.active" disable="tab.disabled">
<uib-tab-heading>
{{tab.title}} <i class="glyphicon glyphicon-remove-sign" ng-click="removeTab($index)"></i>
</uib-tab-heading>
{{tab.content}}
</uib-tab>
</uib-tabset>
</div>


JS Code:

$scope.addTab = function() {
var len = $scope.tabs.length + 1;
var numLbl = '' + ((len > 9) ? '' : '0') + String(len);

var mrkUp = '<div>' +
'<h1>New Tab ' + numLbl + ' {{foo}}</h1>' +
'<div ng-include="tab.tabUrl" class="ng-scope"></div>' +
'</div>';

$scope.tabs.push({title: 'Tab ' + numLbl, content: $compile(angular.element(mrkUp))($scope)});
}


In the Plunker, click the "Add Tab" button. It calls a function in $scope that pushes a new tab to the collection but passing in some dynamically generated content that includes a ng-include directive. The expected output is that the ng-include will be displayed inside of the tab content area.

Thanks

In your Plunker you are using ng-bind-html which doesn't compile the HTML for you. You can create a new directive that does that for you.

Source code for ng-bind-html:

var ngBindHtmlDirective = ['$sce', '$parse', '$compile', function($sce, $parse, $compile) {
  return {
    restrict: 'A',
    compile: function ngBindHtmlCompile(tElement, tAttrs) {
      var ngBindHtmlGetter = $parse(tAttrs.ngBindHtml);
      var ngBindHtmlWatch = $parse(tAttrs.ngBindHtml, function getStringValue(value) {
        return (value || '').toString();
      });
      $compile.$$addBindingClass(tElement);

      return function ngBindHtmlLink(scope, element, attr) {
        $compile.$$addBindingInfo(element, attr.ngBindHtml);

        scope.$watch(ngBindHtmlWatch, function ngBindHtmlWatchAction() {
          // we re-evaluate the expr because we want a TrustedValueHolderType
          // for $sce, not a string
          element.html($sce.getTrustedHtml(ngBindHtmlGetter(scope)) || '');
        });
      };
    }
  };
}];

Pick a name for the new directive, for example compile-html.

Replace tAttrs.ngBindHtml with tAttrs.compileHtml (or whatever name you picked).

You need to replace $sce.getTrustedHtml with $sce.trustAsHtml, or you will get Error: [$sce:unsafe] Attempting to use an unsafe value in a safe context.

Then you need to call $compile:

$compile(element.contents())(scope);

Full directive:

app.directive('compileHtml', ['$sce', '$parse', '$compile',
  function($sce, $parse, $compile) {
    return {
      restrict: 'A',
      compile: function ngBindHtmlCompile(tElement, tAttrs) {
        var ngBindHtmlGetter = $parse(tAttrs.compileHtml);
        var ngBindHtmlWatch = $parse(tAttrs.compileHtml, function getStringValue(value) {
          return (value || '').toString();
        });
        $compile.$$addBindingClass(tElement);

        return function ngBindHtmlLink(scope, element, attr) {
          $compile.$$addBindingInfo(element, attr.compileHtml);

          scope.$watch(ngBindHtmlWatch, function ngBindHtmlWatchAction() {

            element.html($sce.trustAsHtml(ngBindHtmlGetter(scope)) || '');
            $compile(element.contents())(scope);
          });
        };
      }
    };
  }
]);

Usage:

<div compile-html="tab.content"></div>
