使用AJAX更改PHP变量的值

Question

The PHP:

<?php

$mainView = "views/dashboardView.php";

?>

The HTML:

<div class="mainContent">
    <?php include($mainView); ?>
</div>

I would like the click event of a button to change what view .mainContent shows and I believe AJAX can accomplish this but as yet have not been able to get it to work.

Any advice?

You would have to modify your PHP script to allow for this.

For example:

PHP:

if (isset($_POST['change']))
{
    $mainView = $_POST['change'];
    echo $mainView;
}

HTML & jQuery:

<button id="change">Change the var</button>
<script>
$("#change").click(function() {
    $.post("file.php", {change: $(this).val()},
        function (data)
        {
           $("#mainContent").html(data);
        });
});
</script>
