我应该用什么来从PHP中的字段userid和密码中获取值? 我得到一个带有给定代码的空字符串

I have to file main.html(main file) and login.html(contetns only form without html document means body and html tags) and use the .load() method of jquery to load the form from login.html to the main.html and submit to the login.php. And when i try to fetch the value of the input field in php it just give a empty string or say nothing. I don't want to use this method only. So is it wrong or not possible or is there any other php method which is able to fetch these fields.

main.html

    <html>
    <head>
        <title>My Media</title>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
        <!--script src="https://code.jquery.com/jquery-1.11.1.min.js">   </script>
        <script src="https://cdn.jsdelivr.net/jquery.validation/1.16.0/jquery.validate.min.js"></script>
        <script src="https://cdn.jsdelivr.net/jquery.validation/1.16.0    /additional-methods.min.js"></script-->

        <script src="jquery.js"></script>
        <script src="javascript.js"></script>
        <link rel="stylesheet" href="css.css">
    </head>
    <body>
        <div id="nav-placeholder" name="nav-placeholder"></div>
        <div id="body" name="body">
        </div>

    </body>
</html>

login.html

<div id="loginPage">
    <br><h1>My Media</h1><br><br><br>
    <form id="form1" name="form1" method="post" onsubmit="return validate()" action="login.php">
        UserId:<br><input id="userid" name="userid" type="text" required><br>
        Password:<br><input id="password" name="password" type="password" required><br>
        <input id="Login" name="Login" type="submit" value="login">
    </form> 
</div>

jquery.js

$(function(){
    var page="home";
                $("#nav-placeholder").load("menu.html");    
                $("#body").load("home.html")

    $("body").on("click","#home",function(){
        if(page!="home"){
        $("#body").empty();//after("<h3><u>Some appended text.</u></h3>");
        $("#body").load("home.html");
        page="home";}
    }); 

    $("body").on("click","#help",function(){
    if(page!="help"){
        $("#body").empty();//after("<h3><u>Some appended text.</u></h3>");
        $("#body").load("help.html");
        page="help";}
    }); 

    $("body").on("click","#login",function(){
        if(page!="login"){
        $("#body").empty();//after("<h3><u>Some appended text.</u></h3>");
        $("#body").load("login.html");
        page="login";}
    }); 

    $("body").on("click","#register",function(){
        if(page!="register"){
        $("#body").empty();//after("<h3><u>Some appended text.</u></h3>");
        $("#body").load("register.html");
        login="register";}
    });

    $("body").on("click","#about",function(){
        if(page!="home"){
        $("#body").empty();//after("<h3><u>Some appended text.</u></h3>");
        $("#body").load("about.html");
        page="about";}  
    });

    $("body").on("click","#bottom",function(){
        if(page!="home"){
        $("#body").empty();//after("<h3><u>Some appended text.</u></h3>");
        $("#body").focus("#contacts");
        page="about";}  
    });

});

$usrname = $_POST["userid"];
$pass = $_POST["password"];

    You should send the form values in a json format using an ajax call when the user clicks on login.

    var userid = $('#userid').val();
    var password = $('#password').val();
    
    var data = {
      "user_id":userid,
      "homeTown": password
    }
    
    $("#login").click(function(event){
           $.ajax( {
                      url:'login.php',
                      type:'post',
                      success:function(data) {
                         // Allow Login
                      }
                   });
                });
    
    

    Hope it works!!
