Detect array in angular template

Question

I have an array that I am iterating through and displaying. Sometimes, however, the item it finds is an array. I'd like to do something different with this, using an ng-if. I am unsure how to do this easily. It seems like a common issue but there doesn't appear to be an easy solution.

Can you expand your question more? What would you like to do if the item is an array? Can you provide a demo code (plunker)? — Razvan B., May 26 '15 at 10:04

You can use Angular.isArray() (see doc) but it does not exist as a already defined filter so you might need to define your own.

Something like that :

angular.module('...', []).filter('isArray', function() {
  return function (input) {
    return angular.isArray(input);
  };
});

And then in your template usimply use {{ myVar | isArray }}.

My only concerne is ... is it really clean to do so ? I don't know but this will solve your problem.

By the way, was already asked on StakcOverFlow : Angular expression to check if model is array or object
