Ajax-将按钮值发送到php

I have a problem with send data to php. I want to send button value via jquery ajax. This is my code: HTML

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    <script>
$(document).ready(function(){
    $.ajax({
        url: "try.php",
        type: "POST",
        data: {
            data: val    // removed ; after val.
        }
    });
});

</script>

    <body>

      <button id="1" name="1"  value="some_value">1</button>
      <button id="2" name="2"  value="some_value">2</button>


    </body>

PHP:

<?php

$name = $_POST['data'];
echo $name;

?>

It doesn't working...

    Make proper json string to send data. You are having extra ; there.

    $(document).ready(function(){
    $.ajax({
        url: "try.php",
        type: "POST",
        data: {
            data: val    // removed ; after val.
        }
    });
});

    And get it with data key in php.

    <?php

$name = $_POST['data'];
echo $name;
?>

    Also, write your event listeners inside document.ready(). Currently your listeners are not getting applied as the script is on the top and is not able to find the <button> as they are not yet present.
