javascript - Can I use a ternary operator with angularjs outside of the class attribute? -

-

i'm looping through json object angularjs, , having trouble dealing nulls.

i'm new angular.

<a href="#" data-mycustom="{{product.related}}">...</a>

in event of related being null:

{     "related":null }

i want put "-1" in place:

<a href="#" data-mycustom="-1">...</a>

tried ternary operator isn't evaluating... it's displaying plain text.

simply use ng-attr add custom attribute after evaluation of {{}} interpolation directive

markup

<a href="#" ng-attr-data-mycustom="{{product.related || '-1' }}">...</a>
