<?php
$arr['mail_to']="[e-mail]"; //目的地邮箱
$arr['mail_from']="[e-mail]"; //源邮箱
$arr['mail_subject']="subject"; //邮件标题
$arr['mail_body']= "name:".$_POST['txtName']." City:".$_POST['txtCity']."<br />"." Tel:".$_POST['txtTel']." Country:".$_POST['txtCountry']."<br />"." Email:".$_POST['txtEmail']."<br />"." Message:".$_POST['txtMessage']; //邮件正文
$arr['is_html']=True; //是否html邮件，是或否
em_local_send($arr);
echo ' <script language="javascript">';
echo 'alert("Send success.")';
echo 'window.location.href="encontactus.html"';
echo ' </script>';
function em_local_send($arr){
$mail_to = $arr['mail_to'];
$mail_from = $arr['mail_from']=="" ? '[e-mail]' : $arr['mail_from'];
$mail_subject = $arr['mail_subject'];
$mail_body = $arr['mail_body'];
$is_html = $arr['is_html'];

$header = "";
if ($is_html){
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: text/html; charset=UTF-8\r\n";
$header .= "To: $mail_to\r\n";
}
$header .= "From: $mail_from\r\n";
$header .= "Reply-To: $mail_from\r\n";
$header .= "X-Mailer: Heiyeluren-Mailer\r\n";
return mail($mail_to, $mail_subject, $mail_body, $header);
}
?>
echo 'alert("Send success.")'; 这句话 怎么写？ 怎么告诉我js 错误 说少;

em_local_send($arr);
echo ' <script language="javascript">';
echo 'alert("Send success.");';
echo 'window.location.href="encontactus.html";';
echo ' </script>'; 是少了";"号。
