你可以这样添加并尝试:

HTML文件:

<p><input type="text" id="demoDatepicker" /></p>

JavaScript文件:

$(function() {  
    $("#demoDatepicker").datepicker({
        dateFormat: 'dd/mm/yy',
        changeMonth: true,
        changeYear: true,
        constrainInput: false
    });
});

这里有一个特定的代码:

var date = $('#datepicker').datepicker({ dateFormat: 'dd-mm-yy' }).val();

更多信息可在这里:

http://api.jqueryui.com/datepicker/#option-dateFormat http://api.jqueryui.com/datepicker/#utility-formatDate

dateFormat The format for parsed and displayed dates. This attribute is one of the regionalisation attributes. For a full list of the possible formats see the formatDate function. Code examples Initialize a datepicker with the dateFormat option specified. $( ".selector" ).datepicker({ dateFormat: 'yy-mm-dd' }); Get or set the dateFormat option, after init. //getter var dateFormat = $( ".selector" ).datepicker( "option", "dateFormat" ); //setter $( ".selector" ).datepicker( "option", "dateFormat", 'yy-mm-dd' );

最终得到了datepicker日期更改方法的答案:

$('#formatdate').change(function(){
    $('#datpicker').datepicker("option","dateFormat","yy-mm-dd");
});

这里是一个开箱即用的未来证明日期片段。Firefox默认为jquery ui datepicker。否则使用HTML5 datepicker。如果FF支持HTML5 type="date"，脚本将是多余的。不要忘记head标签中需要三个依赖项。

<script>
  src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js">
</script>
<link rel="stylesheet"href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">  
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

<!--Form element uses HTML 5 type="date"-->
<div class="form-group row">
    <label for="date" class="col-sm-2 col-form-label"Date</label>
    <div class="col-sm-10">          
       <input type="date" class="form-control" name="date" id="date" placeholder="date">
    </div>
</div>

<!--if the user is using FireFox it          
autoconverts type='date' into type='text'. If the type is text the 
script below will assign the jquery ui datepicker with options-->
<script>
$(function() 
{
  var elem = document.createElement('input');
  elem.setAttribute('type', 'date');

  if ( elem.type === 'text' ) 
  {
    $('#date').datepicker();
    $( "#date" ).datepicker( "option", "dateFormat", 'yy-mm-dd' );     
  }
});

我正在使用jquery的datepicker。这些jquery就用于此

<script src="jqueryCalendar/jquery-1.6.2.min.js"></script>
<script src="jqueryCalendar/jquery-ui-1.8.15.custom.min.js"></script>
<link rel="stylesheet" href="jqueryCalendar/jqueryCalendar.css">

然后按照这个代码，

<script>
     jQuery(function() {
     jQuery( "#date" ).datepicker({ dateFormat: 'dd/mm/yy' });
                });
</script>
