ng-repeat order by string value

I was wondering if it is possible to order by a list based on a string, for e.g.

I want all the Bear's to come first in my ng-repeat based on item.type.

Bear

item.type

Data:

$scope.Reindeers = [
"name": "Vixen",
"type": "Bear"
,

"name": "Prancer",
"type": "Dog"
,

"name": "Dancer",
"type": "Cat"
,

"name": "Rudolph",
"type": "Bear"
]


AngularJS e.g.

<div class="weird-reindeers" ng-repeat="Deer in Reindeers | orderBy: 'type == Bear'"></div>


Bears

Bears

The argument to orderBy can be a function: https://docs.angularjs.org/api/ng/filter/orderBy#orderBy-arguments

orderBy

Write a function that returns a value used for sorting. The highest priority should return the lowest value:

$scope.orderByBears = function(item)
switch(item.type)
case "Bear":
return -10;
/*case "Dog":
return -5;*/
default:
return 0;




Then use this as your orderBy function:

orderBy

<div class="weird-reindeers" ng-repeat="Deer in Reindeers | orderBy: orderByBears"></div>

The easiest solution is to just use the default alphabetical ordering.

So since bear starts with a b, it's enough to just write:

<div class="weird-reindeers" ng-repeat="Deer in Reindeers | orderBy: 'type'">Deer</div>


See: https://jsfiddle.net/nfje5qo2/6/

As your array is stored in key: value manner. This is easy to sort. You need not require to write any further method or function. Just put a pipeline called filter in Angular terms in your HTML as below.

<div class="weird-reindeers" ng-repeat="Deer in Reindeers | orderBy: 'type'">Deer</div>
