当浏览器或浏览器选项卡关闭时从 jQuery 调用 PHP

Question

Below is jquery code that displays an alert before closing the tab or browser window:

$(window).on('beforeunload', function(){
    if(leave_window == false){
        debugger;
        var i =1;
        i++;
        alert('123'+i);
        return 'Are you sure you want to leave?';
    }  
});

I have a php function sendMail() that I would like to call from this code block but I am struggling to do so. How can I call my php function before the browser closes?

$(window).on('beforeunload', function(){
    if(leave_window == false){
        debugger;
        var i =1;
        i++;


var data = {
    name: $("#form_name").val(),
    email: $("#form_email").val(),
    message: $("#msg_text").val()
};
$.ajax({
    type: "POST",
    url: "email.php",
    data: data,
    success: function(){

    }
});

 alert('123'+i);
        return 'Mail sent Successfully.. Are you sure you want to leave?';
    }  
});

in email.php

<?php
if($_POST){
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['text'];

//send email
    mail("example@gmail.com", "51 Deep comment from" .$email, $message);
}
?>

Try this.. I think, it will give ua better solution for ur pblm
