javascript - Checking for duplicates in while typing in input with ng-model -

let's have array so:

$scope.items = [     {'name': '1'},     {'name': '2'},     {'name': '3'}, ]; 

then have in template:

<div ng-repeat="x in items">     <input ng-model="x.name" /> </div> 

does have ideas on how go not allowing duplicate names? example, if typed in 3rd input box number 1, wouldn't allow it.

use ngblur call following function in controller , pass x it

var validatename = function (xfromview) {      if (items.map(function (x) { return x.name }).indexof(xfromview.name) > -1) {          xfromview.name = null;          //let user know somehow input invalid      } }
