function Test1Controller($scope) {
    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 = [{

    $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 {

                console.log($scope.selection[i].name  +"   "+ $scope.offers[j].modalname)
                if( $scope.selection[i].name == $scope.offers[j].modalname){

您似乎希望迭代$scope.selection而不是$scope.items。

Updated Example

变化：

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

为：

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

由于if中的所有元素都已经过检查，因此删除了$scope.selection条件语句。

或者，您也可以使用.map()方法创建数组：

Updated Example

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

如何在使用angularjs提交后获取复选框值？
