填充表单，以便我可以编辑localStorage数据

Question

我不希望我在Stackoverflow上的第一篇文章成为一个问题，但我是编码的新手，需要一些帮助。我正在尝试使用localStorage数据填充表单字段，以便进行编辑。我整天都在这里。不确定如何正确发布我的代码，所以这里。

它不断抛出“无法读取”1“的属性的错误。我确实得到填写的表单，但它填充了”[object HTMLInputElement]“任何帮助将不胜感激，谢谢

$("#save").click(function (e) {
    alert("Name Has Been Saved");
    e.preventDefault();
    var data = $("#form").serializeArray();
    var id = Math.floor(Math.random() * 10000001);

    var item = {};
    item.first = ["First:", $("#first").val()];
    item.last = ["Last:", $("#last").val()];

    $.each(data, function (i, obj) {
        localStorage.setItem(id, JSON.stringify(item));

    });

});

//Fill with data from localstorage to edit
function editItem(){
    var value = localStorage.getItem(this.key);
    var item = JSON.parse(value);

    $("#form").show(function () {
        $("#userDiv").hide(function () {
        });  
    });

    $("#first").val(item.first[1]);
    $("#last").val(item.last[1]);
}

});

});


function deleteItem() {
    var ask = confirm("Are you sure you want to delete this contact?");
    if (ask) {
        localStorage.removeItem(this.key);
        alert("Contact was deleted!!");
        window.location.reload();
    } else {
        alert("Contact was NOT deleted.");
    }

}

$("#clear").click(function (e) {
    e.preventDefault();
    if(localStorage.length === 0){
        alert("There Is No Info To Clear")
    }else{
        localStorage.clear();
        alert("All Names Have Been Deleted!");
        window.location.reload();
        return false;
    }
});
});

});
