使用AJAX更改PHP变量的值 [英] Change value of PHP variable with AJAX

问题描述

PHP:

<?php

$mainView = "views/dashboardView.php";

?>

HTML:

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

我希望按钮的click事件可以更改.mainContent显示的视图，我相信AJAX可以完成此操作，但仍无法使其正常工作.

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.

有什么建议吗?

推荐答案

您必须修改PHP脚本以允许这样做.

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

例如:

PHP:

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

HTML& jQuery:

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>
