  setInterval(function(){
    if((ctx.result.leave_status === 1)&&!(ctx.result.leave_status === 3) )
    {
       console.log('resp: ' + emailsArray.toString());
       type = res.type.description;
       name = res.name.f_name;
       LeaveDetails.app.models.Email.send({
       to: emailsArray.toString(),
       from: 'gnanaseelan@gmail.com',
       subject: 'Leave Request ',
     // text: 'my text',
      html: '<h1 style="text-align:center;"> Report leave request</h1><h3>' + name + ' have requested leave</h3><ul><li><b>type: </b>' + type + '</li><li><b>duration: </b>' + duration + '</li><li><b>Number of days: </b>' + days + '</li></ul>,
      },
 function(err, mail) {
   console.log('email sent!');
     if(err !== null) {
        log.error({
        type: 'error',
        model: 'leave-details',
        method: 'create (email send)',user_id: ctx.result.user_id,
        err: err,leaveData: ctx.result,}, 'leave request-email-failed');
         } 
    else {
      log.info({
        type: 'success',
        model: 'leave-details',
        method: 'create (email send)',
        user_id: ctx.result.user_id,
        leaveDuration: ctx.result.leave_start_time + " " + ctx.result.leave_end_time,
        err: err
      }, 'leave request-email-success');
    }
        next(err);
      });
    }//if end
   },60000);
  }

您必须清除clearInterval才能停止发送电子邮件，最好的技巧是将时间间隔设置为构造函数中的全局对象，然后在设置某些状态时清除它，例如，如果完成设置为“ true”，则状态为“ finished：false” “，componentWillUpdate中的clearInterval或shouldComponentUpdate中的，如果不这样做，您的间隔永远不会结束，直到您卸载时才会发生
