javascript - 函数不读取对象

Question

有人可以告诉我如何让发送函数从下一个代码中读取电子邮件对象吗？

var email = {
    to: 'google@gmail.com',
    subject: 'new email',
    text: 'helloWorld'
}

function send() {
    var sendMe = new email();
    console.log(sendMe.subject);

}
send();​

我收到此错误，我还尝试按如下方式声明电子邮件:

var email = new object(); 

但没有成功

Uncaught TypeError: object is not a function

您要么尝试执行此操作:

var email = { to: 'google@gmail.com', subject: 'new email', text: 'helloWorld' }

function send()
{
    console.log(email.subject);
}

send();

或者这个

function email()
{
    this.to = 'google@gmail.com';
    this.subject = 'new email';
    this.text = 'helloworld';
}

function send()
{
    var sendMe = new email();
    console.log(sendMe.subject);
}

send();

我不确定是哪一个，所以我举了两个例子。干杯
