使用mailto发送电子邮件：不会填写主题字段

Question

Using the Window.open mailto: to send an email from my app. It opens up the email software and fills in whoever is being emailed just fine, but I can't seem to fill in the subject field.

  methods: {
    email: function(event) {
      let mail =
        "mailto:Test@gmail.com?" +
        "&subject=" +
        escape("This is my subject");
      window.location.href = mail;
    }
  }

Answer 1

It should not have the & if it is the only parameter

methods: {
  email: function(event) {
    let mail =
      "mailto:Test@gmail.com?" +
      "subject=" +
      encodeURIComponent("This is my subject");
    window.location.href = mail;
  }
}
