如何将日期选择器添加到WordPress中的自定义页面?

标签: javascript php jquery wordpress datepicker

我有一个WordPress网站并创建了一个自定义页面(由于连接了一个单独的数据库)。在这个自定义页面上,我正在创建一个高级搜索表单。在搜索表单上,我有一个开始日期datepicker和一个结束日期datepicker。

出于某些明显的原因,我似乎无法将jQuery日期选择器甚至HTML日期选择器用于我的自定义表单编码。我找到了一个有点工作的JavaScript,但问题是当你选择一个日期时,它会把第二天的日期放在文本框中。而另一个问题是日历看起来很糟糕。

现在此表单上还有其他方面,但它们都正常工作。我正在使用PHP和PostgreSQL来获取研究信息。我有下面的标题和表单代码。并提供日期选择器的JavaScript代码链接。

如何更好地选择日期和CSS?

标题:

<link rel="stylesheet" type="text/css" href="/VCSWeb/wp-content/themes/i-excel-child/css/datepicker.css" />
<script type="text/javascript" src="/VCSWeb/wp-content/themes/i-excel-child/js/datepicker.js">
<script type="text/javascript" src="/VCSWeb/wp-content/themes/i-excel-child/js/timepicker.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

<script>
$(function() {
$( "#datepicker" ).datepicker("option","dateFormat","yy-mm-dd");
$( "#format" ).change(function() {
  $( "#datepicker" ).datepicker( "option", "dateFormat", $( this ).val() );
});
});
</script>

形式:

<form role="search" name="remarks_lookup" method="post" class="search-form" action="#samepage" >
<div style="padding-left:10px; width:25%; float:left; margin-top:-20px; ">                              
<label style="font-size:12px;">Start Date: <br />    
<input style="height:22px;" id="start_dt" name="start_date" class='datepicker boxstyle' size='20' placeholder="YYYY/MM/DD" value="" title='YYYY-MM-DD'  />
</label>
</div>                                          
<div style="padding-left:10px; width:75%; float:left; margin-top:-20px;">
<label>End Date: <br />
<input style="height:22px;" id="end_dt" name="end_date"class='datepicker boxstyle' placeholder="YYYY/MM/DD" size='20' value="" title='YYYY-MM-DD' />    
</label>    
</div>
</form>

DatePicker Js:

那么我对日期做错了什么,导致它在第二天点击日期?示例:用户选择2016年8月18日,但点击日期选择器选择8/19/2016。
