Jquery 无法使用Firefox和pear发送邮件

我很困惑，所以请耐心点

我使用pear 1.9.0，我有一个发送电子邮件的简单代码

 <script type='text/javascript'>
function contactsendBack(f){
   //mes is a div to render messages to the user
    document.getElementById("mes").innerHTML="";

   //if the user wants to input some mails to the textfiled, but the textfield is actually empty...
   if(f.elements['pick'].value=="opt"  && f.elements['sendm'].value=="" ){  document.getElementById("mes").innerHTML="Duh, no mails"; return false;}

   //if the user wants to input some mails to the textfiled and also include admin's mail to the list, but the textfield is actually empty...
   else if (f.elements['pick'].value=="admopt"&& f.elements['sendm'].value==""){document.getElementById("mes").innerHTML="Duh, no mails"; return false;}
   else
      {
                  //ok, no errors now, so send to server
             jQuery.post("contactsendBack.php", { 
              name : f.elements['name'].value ,
              mymail : f.elements['mymail'].value ,
              pick : f.elements['pick'].value ,
              sendm : f.elements['sendm'].value ,
              subj : f.elements['subj'].value ,
              comment : f.elements['comment'].value 


              }, function(data) {
             //render what  contactsendBack.php echos...could be "send ok" or "error"
              $('#mes').html(data);
               });   

       return false;

       }
    }

     </script>


//        the html
        <form  action="#"  onSubmit="return contactsendBack(this); return false;" method="post" enctype="multipart/form-data">   
        Name:<br>
        <input name="name" id="name" type="text" required ><br>
        Your e-mail:<br>
        <input name="mymail" id="mymail" type="email"  value="<?php echo $defm ?>" required ><br>

        <input type="radio" id="pick" name="pick" value="adm" checked = "checked">Admin<br>
        <input type="radio" id="pick" name="pick" value="opt">What I set to the textbox<br>
        <input type="radio" id="pick" name="pick" value="admopt">Admin AND What I set to the textbox<br>
        <input type="radio" id="pick" name="pick" value="all">Everyone<br>


        Set some mails:<br>You can input more than one mail. Separate by commas<br>
        <input name="sendm" id="sendm" type="textarea"  rows="24" cols="50"  ><br>

        Subject:<br>
        <input name="subj" id="subj" type="text"  required><br>
        Text :<br>
        <input name="comment" id="comment" type="textarea"  rows="24" cols="50"  required >
         <br>

         <input type="reset"  id="res" name="res"/>
         <input type="submit" id="sub" name="sub"/>
        </form>

函数contactsendBack（f）{
//mes是向用户呈现消息的div
document.getElementById（“mes”）.innerHTML=“”；
//如果用户想在textfield中输入一些邮件，但textfield实际上是空的。。。
if（f.elements['pick'].value==“opt”&f.elements['sendm'].value==”）{document.getElementById（“mes”）.innerHTML=“Duh，无邮件”；返回false；}
//如果用户希望在文本字段中输入一些邮件，并在列表中包含管理员的邮件，但文本字段实际上是空的。。。
else if（f.elements['pick'].value==“admopt”&&f.elements['sendm'].value==”）{document.getElementById（“mes”）.innerHTML=“Duh，无邮件”；返回false；}
其他的
{
//好的，现在没有错误，所以发送到服务器
post（“contactsendBack.php”，{
名称：f.elements['name'].值，
mymail:f.elements['mymail'].value，
拾取：f.elements['pick'].值，
sendm:f.elements['sendm'].值，
subc:f.元素['subc'].值，
注释：f.elements['comment'].value
}，函数（数据）{
//呈现contactsendBack.php回声…可能是“发送确定”或“错误”
$（'#mes'）.html（数据）；
});   
返回false；
}
}
//html
