在Datepicker中将日期格式更改为yyyy-mm-dd

Question

我在我的HTML字段中使用Datepicker.HTML代码是:

<input type="text" id="from-datepicker"/>

用于设置和获取日期选择器字段的Jquery代码是:

 $("#from-datepicker").datepicker({ dateFormat: 'yy-mm-dd'});
            $("#from-datepicker").on("change", function () {
                var fromdate = $(this).val();
                alert(fromdate);
            });

但是,此代码以'mm-dd-yyyy'格式显示字段.谁能告诉我哪里出错了？

我导入的CDN是:

 <script type="text/javascript"
            src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.6.0/js/bootstrap-datepicker.min.js"></script>

    <link rel="stylesheet" type="text/css"
          href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.6.1/css/bootstrap-datepicker3.min.css">

提前致谢.

是的,将dateFormat更改为只是格式,你需要4套'y'

示例代码:

<script   src="https://code.jquery.com/jquery-2.2.3.min.js"   integrity="sha256-a23g1Nt4dtEYOj7bR+vTu7+T8VP13humZFBJNIYoEJo="   crossorigin="anonymous"></script>

$( document ).ready(function() {
    $("#from-datepicker").datepicker({ 
        format: 'yyyy-mm-dd'
    });
    $("#from-datepicker").on("change", function () {
        var fromdate = $(this).val();
        alert(fromdate);

<input type="text" id="from-datepicker"/>
