angularjs - how to get in the controller the index of an item in a ng-repeat filter based on the value of one of its properties? -

i use ng-repeat in html file display filtered items:

<li ng-repeat="item in (filtereditems = (items | filter:query))">   {{ item.name }} </a> 

in controller, i'd index of item based on 1 of property.

precision: i'd index in filtered list , not in whole list.

here example, index of item witch name some_item_7.

var app = angular.module('myapp', []);  app.controller('myctrl', ['$scope',   function myctrl($scope) {      $scope.query = 'some';      $scope.items =      [       { name: 'some_item_1' },       { name: 'another_item_2' },       { name: 'some_item_3' },       { name: 'another_item_4' },       { name: 'some_item_5' },       { name: 'another_item_6' },       { name: 'some_item_7' },       { name: 'another_item_8' },       { name: 'some_item_9' }     ];      $scope.itemnext = function (item) {       console.log(item.name);     };      $scope.getindexfromname = function (name) {       console.log("trying index of item name = " + name);     }      $scope.getindexfromname('some_item_7');    } ]);

any idea ?

your ng-repeat expression creates filteredlist array on scope.
<li ng-repeat="item in (filtereditems = (items | filter:query))">

you can loop through array, checking item matching name parameter. $scope.filtereditems

update
comments indicate don't want wait ng-repeat create array of filtered items. can use $filter service initialize same array before page loads. use:

$scope.filtereditems = $filter('filter')($scope.items, {name: $scope.query}, false) 

doing not interfere ng-repeat saving filter results same filtereditems array during dom creation.
