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答案

【问题标题】：Changed date is not fire when I am changing it in Bootstrap Date Range Picker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

【问题描述】：

在下面的代码中，我想在 cashadvancefrom 和 to 变量中更新输入选择的日期（通过 Bootstrap 日期范围选择器） /strong> 查询。我认为它们是日期范围选择器回调函数的问题。

range_to 和 range_from 两个变量的值在输入标签中使用 id=reservation 获取，然后使用isset($_GET[range]) 从 from 和 to 获取它们的值，但它没有工作。

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)));
    ?>

【解决方案1】：

如果对象绑定了事件，请检查您的浏览器。如果没有，您可能需要等待文档准备好后再进行绑定：

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