特定日期格式的正则表达式 [英] regex for a particular date format

问题描述

我想要一个用于日期格式的正则表达式，例如: 2011年1月1日

I want to have a regex for a date format, Example: 01-Jan-2011

我写了^[0-9]{1,2}-[a-zA-Z]{3}-[0-9]{4}，但没有检查所有有效日期，例如50-AAA-2011也将被视为有效.

I have written ^[0-9]{1,2}-[a-zA-Z]{3}-[0-9]{4} but does not check for all the valid dates like 50-AAA-2011 will also be considered as valid.

我正在使用JavaScript中的实时验证 lib

I am using Live Validation lib in javascript

我的代码

var sayDate = new LiveValidation('date');
    sayDate.add( Validate.Format, { pattern: /^[0-9]{1,2}-[a-zA-Z]{3}-[0-9]{4}/i });

请帮助！

推荐答案

尝试使用正则表达式验证日期格式实际上比听起来复杂得多.您可以很轻松地进行基本验证，但是要使其完美，总是有很多工作要做.

Trying to validate a date format using regex is actually a lot more complex than it sounds. You can do basic validation quite easily, but there's always that bit more to do to get it perfect.

我建议使用日期选择器控件代替它，它可以为您进行验证(并且还为您提供漂亮的闪亮用户界面功能)，或者可以使用现有的Javascript库之一来处理日期你.

I would suggest instead using either a date picker control, which can do the validation for you (and also gives you the bonus of a nice shiny user interface feature), or else one of the existing Javascript libraries which can handle dates for you.

对于日期选择器控件，有任意数量的jQuery选项.对于日期处理库，我建议查找 date.js .

For date picker controls, there are any number of jQuery options. For date handling libraries, I would suggest looking up date.js.
