当我在 Bootstrap 日期范围选择器中更改日期时，更改的日期不会触发

Changed date is not fire when I am changing it in Bootstrap Date Range Picker

在下面的代码中，我想更新 from 和 to[=26 中的输入选定日期（通过 Bootstrap 日期范围选择器） =] cashadvance 查询中使用的变量。 我认为他们是日期范围选择器回调函数中的问题。

两个变量 range_to 和 range_from 值在带有 id=reservation 的输入标签中获取，然后使用 isset($_GET[range]) 从和到中获取它们的值，但它不起作用。

代码：payrol.php

<?php
    include('db.php');
        $range_to = date('m/d/Y');
        $range_from = date('m/d/Y', strtotime('-30 day', strtotime($range_to)));
    ?>

在浏览器中检查对象是否绑定了事件。如果没有，您可能需要在绑定之前等待文档准备就绪：

$(document).ready(function(){
     $("#reservation").on('change', function(){
        var range = encodeURI($(this).val());
        window.location = 'payrol.php?range='+range;
     });
 });
