angularjs limitTo过滤器不适用于奇数json数组

Question

I have an odd json array that I can ng-repeat just fine, but I'm having trouble limiting this list with the limitTo filter. I'm getting the json object with an http call so I can't change how the object is formed on the back-end.

HTML:

<div ng-controller="myCtrl">
    <div ng-repeat="school in schoolList | limitTo:2">
        {{school.school_name}}
    </div>
</div>

JSON:

{"0":{"school_name":"FAKE ELEMENTARY"},
 "1":{"school_name":"CENTRAL HIGH"},
 "2":{"school_name":"OAK RIDGE ELEMENTARY"},
 "3":{"school_name":"PINE MEADOW ELEMENTARY"},
 "4":{"school_name":"AMERICAN MIDDLE"},
 "5":{"school_name":"BIG SENIOR HIGH"},
 "6":{"school_name":"ST FRANCIS ELEMENTARY SCHOOL"}

Here is the jsfiddle

My first thought is that I could somehow use $index but I haven't had any luck thus far. Any help would be appreciated. I apologize in advanced if this has already been answered but I've been searching for a few days without finding anything helpful. Thanks.

From the angular source the first check is:

if (!isArray(input) && !isString(input)) return input;

So you will have to convert that data to an array, see working fiddle here: http://jsfiddle.net/Nu7rZ/103/
