Window.Open in chrome打开popus和新标签页

Question

我在chrome中有一个奇怪的问题，我使用window.open打开一个新选项卡并使用tcpdf创建pdf，然后将其作为附件发送到特定地址，现在在铬中发生的是它发送2封邮件。如果弹出窗口被启用，那么我会得到2个窗口操作1.弹出窗口和2.新标签，首先我不明白怎么可能，我从来没有见过这个。

然后如果禁用弹出窗口，它只会在新标签页中打开，但仍然是2封邮件。

用于调用弹出页面和电子邮件代码的代码如下所述。请帮忙。

window.open('/loancal/rhexportemail.php' + qstring,"_blank"); 
//Code used to open popup 

//------------- EMAIL CODE ----------------// 
$to = "someone@gamil.com"; 
$from = "info@mydomain.com"; 
$subject = "Loan Enquiry Calculation Cashback - " . $client; 
$message = "Please find attached Loan Enquiry Calculation Cashback statement for ".$client."." ; 

//a random hash will be necessary to send mixed content 
$separator = md5(time()); 

// carriage return type (we use a PHP end of line constant) 
$eol = PHP_EOL; 

// attachment name 
$filename = $subject.".pdf"; 

// encode data (puts attachment in proper format) 
$pdfdoc = $pdf->Output('LECC'.$separator.'.pdf', 'S'); 
$attachment = chunk_split(base64_encode($pdfdoc)); 

// encode data (multipart mandatory) 
$headers = "From: ".$from.$eol; 
$headers .= "MIME-Version: 1.0".$eol; 
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol.$eol; 
$headers .= "Content-Transfer-Enconding: 7bit".$eol; 
$headers .= "This is a MIME encoded message.".$eol.$eol; 

// message 
$headers .= "--".$separator.$eol; 
$headers .= "Content-Type: text/html; charsrt=\"iso-8859-1\"".$eol; 
$headers .= $message.$eol.$eol; 

// attachment 
$headers .= "--".$separator.$eol; 
$headers .= "Content-Type: application/octet-stream; name=\"".$filename."\"".$eol; 
$headers .= "Content-Transfer-Encoding: base64".$eol; 
$headers .= "Content-Disposition: attachment".$eol.$eol; 
$headers .= $attachment.$eol.$eol; 
$headers .= "--".$separator."--"; 

// send message 
if(@mail($to, $subject, $message, $headers)) 
{ 

echo "<script type='text/javascript'> alert('mail sent');window.close();</script>"; 

} 
else{ 
echo "<script type='text/javascript'>alert('mail not sent');window.close(); </script>"; 
    }
