如何在div中运行php函数而无需每次刷新

Question

So I have a PHP script that runs every time the page is refreshed. I also have a button that is labeled "Spin Number" that refreshes the page.

Website URL (Check for yourself)

So as you can see, once you refresh, the picture inside the square changes, so does the random number.

The following script runs every time the page is refreshed. I want this code to run when the button is pressed inside the square.

<?php 
    $mainText = "black";
    $mainNumber = "red";
    $animation = "animated rubberBand";
    $font = "font-family: 'Montserrat', sans-serif;";
    $var = rand (1,110);

    switch($var) {
        case 1:
        case 2:
        case 3:
        case 4:
        case 5:
        case 6:
        case 7:
        case 8:
        case 9:
        case 10:
            echo '<p style="color:'.$mainText.';text-align:center;'.$font.'">You got a Respin!</p>';
            echo '<img class = "'.$animation.'" src="respin3.png" width=300 height=300 style="display:block;margin-left:auto;margin-right:auto;"/>';
            echo '<p style="color:'.$mainText.';text-align:center;'.$font.'">Your random number was '.'<span style="color:'.$mainNumber.'">'.$var.'<span>'.'</p>';
            break;
        case 11:
        case 12:
        case 13:
        case 14:

            break;
        };
?>

I have used a

<?php include 'random.php'; ?> 

for the script to run in that page.

If you want to load up a php snippet dynamically, you're going to need ajax . Specifically something like this:

var jqxhr = $.ajax( "example.php" )
    .done(function() {
        alert( "success" );
    })
    .fail(function() {
        alert( "error" );
    })
    .always(function() {
        alert( "complete" );
    });

Then:

$('body').append(jqxhr)

(I took the above from the jQuery site)
