您已经注释掉了几乎所有的代码
您应该取消对JavaScript代码的注释，以产生以下结果：

函数copyaddress（）{
//从myaddress复制到billingaddress
document.forms[“myForms”][“myaddress”].value=
document.forms[“myForms”][“billingaddress”]。值；
警告（“未选中复选框！”）；
}
函数OrderSubmitted（）{
//检查firstname是否为空
var x=document.forms[“myForms”][“firstname”].value；
如果（x==“”）{
警告（“必须填写姓名”）；
返回false；
}
//检查lastname是否为空
var x=document.forms[“myForms”][“lastname”].value；
如果（x==“”）{
警告（“必须填写姓氏”）；
返回false；
}
警报（“订单已提交！”）；
}

我删除了评论并修复了>但是我的副本地址仍然不起作用

function copyaddress() {
    // copy from myaddress to billingaddress
    document.forms["myForms"]["myaddress"].value =
    document.forms["myForms"]["billingaddress"].value;


    alert("checkbox not checked!");
}
function OrderSubmitted() {
    // check if firstname is blank
    var x = document.forms["myForms"]["firstname"].value;

        return false;
    }
