javascript - Preselected ng-select value issue -

i'm trying preselected value within , i've tried multiple tutorials , looked answers here none worked. here's deal ->
load shifts $http.get("api/shifts"), then:

 <select multiple class="form-control" ng-options="shift shift.nom shift in shifts" ng-model="selectedshift"></select> 

and goes modal window. before modal window opens, can preselect shift (to see able it). in case, have

 if(preselectedshift){   $http.get("api/shifts/"+preselectedshift._id).success(function(shift){     $scope.selectedshift = shift; //so it's replacing ng-model in <select>   }) } 

and shifts appear should, gives me no preselected shift. tried loop.

for (shifts.length) -> if(shift[i]._id == preselectedshift._id) ->$scope.selectedshift = shift[i] 

which gave me error "value.foreach not function"

nor ng-select="shift._id == preselectedshift._id" has worked (gives same error).

thank in advance!

i think you're pretty close solution, it's foreach not supported natively, if use loop should good:

$scope.selectedshift = []; if(preselectedshift){     $scope.selectedshift.length = 0;     $http.get("api/shifts/"+preselectedshift._id).success(function(shift){         for(var x = 0; x < $scope.shifts.length; x++){             if($scope.shifts[x]['_id'] === shift['_id']){                 $scope.selectedshift.push($scope.shifts[x]);             }         }     }) }    

the reason have because in ng-options use shift shift.nom ... means in order selected has same reference array not equaling it. here's quick example explaining (hopefully) how angular checks see if select something:

var mytest = { test: 4}; var myarray = [{ test: 4 }]; var mytest2 = myarray[0];  console.log(myarray[0] === mytest); //this outputs false console.log(myarray[0] === mytest2); //this outputs true
