离子本地电子邮件作曲家 - 将ngmodel作为数组传递

Question

我正在使用Ionic的电子邮件作曲家插件，并希望从页面中获取输入，并将它们作为数组传递到电子邮件中，以便可以立即通过电子邮件发送多个用户。当前，只有第一封电子邮件正在通过，并不是全部。

HTML是：

<ion-content>
   <ion-item id="row" *ngFor="let emailinput of emailinputs ; let i = index">
      <ion-label fixed id="label">
        Email
      </ion-label>
         <ion-input type="email" id="email" placeholder="[e-mail]" (keyup.enter)="Send($event.target.value)" [(ngModel)]="emailinputs[i].email"></ion-input>
   </ion-item>
   <div padding>
      <button (click) = "addnewemail()" id="register" ion-button full color="nudgetprim" block>Add</button>
      <button (click) = "sendinvite(emailinputs.email)" id="register" ion-button full color="nudgetprim" block>Invite</button>
   </div>
</ion-content>

打字稿是：

sendinvite() {
      var bcc = [];
      for(var e in this.emailinputs){
      if (this.emailinputs[e].email==null || this.emailinputs[e].email=="" || !this.emailinputs[e].email.includes("@") || !this.emailinputs[e].email.includes("."))
        {
          let alert = this.alerCtrl.create({
                title: 'Error!',
                message: 'There was an error with an email address you entered.',
                buttons: ['Ok']
              });
              alert.present()
            }
      else {
      bcc.push(this.emailinputs[e].email);
      this.emailComposer.isAvailable().then((available: boolean) =>{
       if(available) {
         //Now we know we can send
       }
      });
      let email = {
        // to: this.emailVal,
        // cc: '[e-mail]',
        bcc: bcc,
        attachments: [
          'file://img/logo.png',
          'res://icon.png',
          'base64:icon.png//iVBORw0KGgoAAAANSUhEUg...',
          'file://README.pdf'
        ],
        subject: 'Nudget Invite',
        body: '<a href="">Join my grocery list!</a>',
        isHtml: true
      };
      // Send a text message using default options
      this.emailComposer.open(email);        }}
    }

bcc没有正确填充。我该如何解决？

对属性支持字符串。您必须将数组转换为字符串。

您可以以这种方式转换。

const emailVal = ['[e-mail]', '[e-mail]'];
let emailTo = '';
emailVal.map((email, index) => {
    console.log(email, index)
    if (index === emailVal.length - 1) {
      emailTo = emailTo + email;
    } else {
        emailTo = emailTo + email + ', ';
    }
});
console.log(emailTo);
// result
// "[e-mail], [e-mail]"
