如何在angularjs中将数组推入另一个数组

this.addToCart = function(id,name,category,price) {

        alert(id+"name"+name);
        var eachProduct = [
                {
                    "name": name,
                    "id": id,
                    "category":category,
                    "price":price
                }
            ];

        //$scope.obj = item;
        //alert($scope.obj.name);
        alert("product Name :"+eachProduct[0].name);

        var arrayList = [];
        arraylist.push(eachProduct);

        sessionStorage.setItem("addedProductsList", eachProduct);

        return "success";

我正在从sessionStorage检索值arrayList

var retrieveArray= sessionStorage.addedProductsList;
alert(retrieveArray.eachProduct[0].name);//getting undefined

我正在另一项服务中检索如何将每种产品推入arrayList并将其存储在会话存储中。
