javascript - 将简写 JS 添加到父级

我正在创建一些速记 js 变量，这些变量最终将合并到父级中以创建一些 XML。我的速记 js 在这里做错了什么？我有点迷路了。

我想出了这个简短的例子来概述我的问题:

function testing() {
  var attachments = [];

  var attachment1 = [ "attachment" ,
                     [ "name", "myname1" ],
                     [ "type", "mytype1" ]
                    ];
  attachments.push(attachment1);
  var attachment2 = [ "attachment" ,
                     [ "name", "myname2" ],
                     [ "type", "mytype2" ]
                    ];
  attachments.push(attachment2);

  var email = [ "email",
               [ "subject", "mySubject"],
               [ "body", "myBody"],
               [ "attachments", attachments ]
              ];
  Logger.log(Xml.parseJS(email).toXmlString());
}

日志输出:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<email>
    <subject>mySubject</subject>
    <body>myBody</body>
    <attachments>[Ljava.lang.Object;@b06f679</attachments>
</email>

理想情况下，它应该是:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<email>
    <subject>mySubject</subject>
    <body>myBody</body>
    <attachments>
        <attachment>
            <name>myname1</name>
            <type>mytype1</type>
        </attachment>
        <attachment>
            <name>myname2</name>
            <type>mytype2</type>
        </attachment>
    </attachments>
</email>

最佳答案

您正在将一个数组放在一个数组中。

var attachment1 = [ "attachment" ,
                   [ "name", "myname1" ],
                   [ "type", "mytype1" ]
                  ];

var attachment2 = [ "attachment" ,
                   [ "name", "myname2" ],
                   [ "type", "mytype2" ]
                  ];


var email = [ "email",
             [ "subject", "mySubject"],
             [ "body", "myBody"],
             [ "attachments"]
            ];
email[3].push(attachment1);
email[3].push(attachment2);

您可以使用 console.log(email) 查看网络浏览器结构的不同

这也会让同样的事情更具可读性

attachments = ["attachments"];
attachments.push(attachment1);
attachments.push(attachment2);
var email = [ "email",
              [ "subject", "mySubject"],
              [ "body", "myBody"],
              attachments
            ];
