AngularJS ngOptions sort array

Question

I have been trying to use ng-options to display an array of fonts in a select sorted alphabetically by the value of the items in the array.

HTML

<select ng-options="font for font in webfonts | orderBy:'font'" name="fonts">
     <option value="">Choose a font</option>
</select>

JS

$scope.webfonts = [ 
        'Abel', 'Crafty Girls' , 'Lato' , 'Average',
        'Corben', 'Quicksand', ... ];

I've tried changing the value in orderBy and other things. I've read through the documentation and all comments.

What am I missing? Is this supposed to only work on objects?

Answer 1

This is what you need to do:

<select ng-model="selected" ng-options="font for font in webfonts | orderBy:'toString()' " name="fonts">

1. You need to add ng-model to correctly make the binding works for a list of strings.
2. You can use toString() to sort if the input contains a list of strings. Since the expression of orderBy can be a Getter function. The result of this function will be sorted using the <, =, > operator.
