jquery .post 无法将值传递给 php 进行检查

Question

我在 jquery - Post 中有一个问题。当我在表单中输入电子邮件时，js - jquery 会将电子邮件传递到 sendResetPasswordMail1.php 以检查电子邮件是否有效。

但是现在，$.post("sendResetPasswordMail1.php",mail:email},function(resetPasswordMsg) 不能在js中工作了。

我找不到哪里错了。苦恼。 请问你能帮帮我吗。 非常感谢。

php

<!--reset Password Popup start-->

js - jquery

$(function(){

        var email = $("#resetPasswordEmail").val();
        var preg = /^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/; //match Email

php - sendResetPasswordMail1.php

$email = stripslashes(trim($_POST['mail']));
$sql = "select * from user where email='$email'";
$query = mysql_query($sql);
$num = mysql_num_rows($query);
if($num==0){//The mailbox is not registered yet! Return 'noRegister'
    $resetPasswordMsg = "noRegister";
    echo $resetPasswordMsg;
    exit;   
}

阻止默认点击事件

$("#subSendResetPassword_btn").click(function(e){
   e.preventDefault()
});
