jquery datepicker:验证当前输入值? [英] jquery datepicker : Validate current input value?

问题描述

我一直在使用 jQuery UI 中的 Datepicker 插件.我希望能够验证它所附加的输入文本框当前是否具有有效日期.

I've been using the Datepicker plugin from jQuery UI. I want to be able to validate if the input textbox it is attached to currently has a valid date or not.

例如:

如果有人决定输入 02/30/2010 我希望能够以某种方式询问插件当前输入值是否是有效日期(在这种情况下不是).

If someone decides to type in 02/30/2010 I'd like to be able to somehow ask the plugin if that current input value is a valid date (which it is not in this case).

有谁知道如何做到这一点?

Does anyone know how this can be done?

推荐答案

您可以通过将文本框设为只读并根据需要设置日期格式来解决您的问题.因此用户无法在文本框中键入任何内容，用户只能从日期选择器中选择正确的日期格式(您设置的).请看下面的例子.

You can solve your problem by making text box read only and set date format as you like. So User is not able to type anything in text box, user only select correct date format(which you set) from date picker. Please see the below example.

<p>Date: <input type="text" id="datepicker" size="30" readonly="readonly"/></p>    
<script>
$(function() {
    $( "#datepicker" ).datepicker();
    $( "#datepicker" ).datepicker( "option", "dateFormat",'yy-mm-dd');
});
</script>
