    var storeid = window.localStorage.getItem("storeid"); 
 
    var serverData = ["Samsung Galaxy Note", "Samsung Galaxy S6", "Samsung Galaxy Avant","Samsung Galaxy Young"]; 
 
    $scope.items= [] ; 
 
    $scope.selection = [];  
 
    $scope.offers = [{ 
 
     id: "as23456", 
 
     Store: "samsung",

    },] 
 
    
 
    $scope.toggleSelection = function toggleSelection(item) { 
 
     $scope.gotOffers=[]; 
 
     var idx = $scope.selection.indexOf(item); 
 

 
     // is currently selected 
 
     if (idx > -1) { 
 
      $scope.selection.splice(idx, 1); 
 
     } 
 

 
     // is newly selected 
 
     else { 
 
      $scope.selection.push(item); 
 
     } 
 

 
     for(var i=0;i<$scope.selection.length;i++){ 
 
      for(var j=0;j<$scope.offers.length;j++){ 
 
       console.log($scope.selection[i].name +" "+ $scope.offers[j].modalname) 
 
       if($scope.selection[i].name == $scope.offers[j].modalname){ 
 
        var idx = $scope.gotOffers.indexOf($scope.offers[j].Offer_message); 
 
        if(idx == -1){ 
 
         console.log("inside idx") 
 
         $scope.gotOffers.push($scope.offers[j]); 
 
        } 
 
       } 
 
      } 
 
     } 
 
\t \t console.log($scope.offers); 
 
    }; 
 
    
 
\t var selectedvalue = window.localStorage.getItem("selectedvalue"); 
 
\t // here selected value Samsung Galaxy S6 
 
    var selectedvalue="Samsung Galaxy S6,Samsung Galaxy Young"; 
 
    for(var i=0;i<serverData.length;i++){ 
 
     var modal = { 
 
      name:serverData[i], 
 
      selected:false 
 
     }; 
 
\t \t if (selectedvalue.indexOf(serverData[i]) >= 0 || null){ 
 
      $scope.toggleSelection(modal); 
 
     } 
 
     $scope.items.push(modal);   
 
    } 
 
    //----------------------------Our Shop Offers---------------------------------------- 
 
    $scope.check = function(){ 
 
     var checkedItems = []; 
 
     console.log($scope.offerSelected) 
 
     for(var i=0;i<$scope.items.length;i++){ 
 
      if($scope.items[i].selected){ 
 
       checkedItems.push($scope.items[i].name); 
 
      }

Answer 1

好像你是想遍歷$scope.selection而非$scope.items。

Updated Example

變化：

var checkedItems = [];$scope.selection 
for (var i = 0; i < $scope.items.length; i++) { 
    if ($scope.items[i].selected) { 
    checkedItems.push($scope.items[i].name); 
    } 
} 

到：

var checkedItems = []; 
for (var i = 0; i < $scope.selection.length; i++) { 
    checkedItems.push($scope.selection[i].name); 
} 

除去if條件語句，因爲在$scope.selection所有元素都已經檢查。

或者，您也可以只使用.map()方法來創建數組：

Updated Example

var checkedItems = $scope.selection.map(function(checkbox) { 
    return checkbox.name; 
});
