如何在不刷新网页的情况下分配$ _GET变量？

I have a table on my website that is populated with values for each row, and here is a sample code:

//JAVASCRIPT
<tr onclick="window.history.replaceState(null, null, 'myPage.php?ID=2');">

The URL is changing, however it does not assign $_GET variable in PHP when using 'history.replaceState' function

Here is code to check whether ID has been assigned:

//PHP
if (isset($_GET["ID"])) {
    // do something
}

I can use different function which is

//JAVASCRIPT
<tr onclick="window.location.replace('myPage.php?ID=2');">

Here, the URL is changing and the variable is actually populated with 2, however the website is refreshing as well which is something I want to avoid.

I checked many articles online and apparently you can use AJAX, however I have no experience in AJAX, that's why I could use some help

You need to use ajax
try this

//html
<tr onclick="sendData('file.php','2');">


//PHP file.php
if (isset($_GET["ID"])) {
    // do something
}
return true;




      //JS
    function sendData( file, id){

window.histor`enter code here`y.replaceState(null, null, file+'?ID='+id);
        $.ajax({
        url: file,
        type:GET,
        data:{ID:id},
         success: function(result){
               console.log(result)
            }});

    }
