[$sanitize:badparse] sanitizer unable parse following block of html: 

i don't want use trustashtml because don't trust our sanitizer , want ensure not display unsafe html on page.

according ngbindhtmldirective can this:

html:

<div ng-if="issafehtml()">   <div ng-bind-html="invalidhtml"></div> </div> <div ng-if="!issafehtml()">   {{invalidhtml}} </div>  

js:

$scope.issafehtml = function() {    return !!$sce.gettrustedhtml($scope.invalidhtml); }
