Jquery Validation插件验证日期如20 / August / 2013 Safari Bug?

标签: jquery regex validation safari jquery-validate

我使用Jquery Validation插件并验证事件日期,如

rules:{
       eventdate: 
       {
       required:true,   
       date: true
       }
     }
  

日期格式类似于“23 / August / 2013”​​('dd / MM / yy')

但代码在 Safari 上失败,在Fx,chrome,opera等方面效果更好......

  

是Safari Bug还是Jquery Validation插件错误?

我知道Jquery Validation插件支持自定义验证,如

$.validator.addMethod("customdateValidateRule", function(value, element) 
{  
_isvalidResult=****testfn()***;
return _isvalidResult;
}

我试过Custom date format with jQuery validation plugin 但是dd/mm/yyyy不是('dd/MM/yy'),而是23/August/2013"的正则表达式,我不知道!

说明

1)我使用Datepicker(JqueryUi)来选择日期
2)我正在使用Jquery Validation插件(最新版),它将验证很多日期格式,它也验证了“23 / August / 2013”​​(我假设)但是当我在Safari中测试它时显示无效在FX,Chrome,Opera中显示“有效”的地方..

问题是因为Safari无法正确处理格式。 JQuery验证插件工具无法验证此格式(仅在ChromeSafari中发生)。要解决此问题,请修改验证插件。

如果您想为dd/mm/yy自定义,可以这样做。

$.validator.addMethod(
   "customdateValidateRule", 
   function(value, element) {
      return value.match(/^\d{1,2}\/\d{1,2}\/\d{2}$/);
   },
      "Input a date format of dd/mm/yy:"
);

并将规则验证添加到表单中。

$('#myformname')
   .validate({
       rules : {
        myDate : {
          customdateValidateRule : true
        }
       }
   });

如果您想要添加测试方法,您应该可以执行类似..

的操作
var isdate = function(value) {
    var isvalid = /^(\d{1,2})\/(\d{1,2})\/(\d{2})?$/;   
    return isvalid.test(value);
} 

$.validator.addMethod(
   "customdateValidateRule",
   function(value, element) {
      return isdate(value);
   }
);

如果您需要正则表达式来验证dd/mm/yyyy,请将其更改为..

/^\d{1,2}\/\d{1,2}\/\d{4}$/

要验证23/August/2013日期的具体信息,您可以在此处选择几个选项。

有简短的方法:

/^\d{1,2}\/\b[a-zA-Z]+\/\d{4}$/

正则表达式解释:

^              the beginning of the string
 \d{1,2}       digits (0-9) (between 1 and 2 times)
  \/           look for and match '/'
   \b          the boundary between a word char (\w)
    [a-zA-Z]+  any character of: 'a' to 'z', 'A' to 'Z' (1 or more times)
  \/           look for and match '/'
  \d{4}        digits (0-9) (4 times)
$              before an optional \n, and the end of the string

漫长的路(具体验证):

/^\d{1,2}\/\b(?:Jan(?:uary)?|Feb(?:ruary)?|Mar(?:ch)?|Apr(?:il)?|
                May|Jun(?:e)?|Jul(?:y)?|Aug(?:ust)?|Sept?|September|
                Oct(?:ober)?|Nov(?:ember)?|Dec(?:ember)?)\/\d{4}$/

正则表达式解释:

^                     the beginning of the string
 \d{1,2}              digits (0-9) (between 1 and 2 times)
  \/                  look for and match '/'
   \b                 the boundary between a word char (\w)
    (?:               group, but do not capture:
     Jan(?:uary)?|    'Jan', group but don't capture optional 'uary', OR
     Feb(?:ruary)?|   'Feb', group but don't capture optional 'ruary', OR
     Mar(?:ch)?|      'Mar', group but don't capture optional 'ch', OR
     Apr(?:il)?|      'Apr', group but don't capture optional 'il', OR
     May|             'May', OR
     Jun(?:e)?|       'Jun', group but don't capture optional 'e', OR
     Jul(?:y)?|       'Jul', group but don't capture optional 'y', OR
     Aug(?:ust)?|     'Aug', group but don't capture optional 'ust', OR
     Sept?|           'Sep', 't' optional, OR
     September|       'September', OR
     Oct(?:ober)?|    'Oct', group but don't capture optional 'ober', OR
     Nov(?:ember)?|   'Nov', group but don't capture optional 'ember', OR
     Dec(?:ember)?    'Dec', group but don't capture optional 'ember'
    )                 end of grouping
     \/               look for and match '/'
      \d{4}           digits (0-9) (4 times)
$                     before an optional \n, and the end of the string

如你所说,如果你正在使用JqueryUi Datepicker,你有2种方法

1)正如@hwnd所说,你必须编辑验证器插件
2)只需添加我的黑客并对它感到满意!

    /*Override the validator's Date Validation with mine! */
    $.validator.methods.date=
    function(value, element) {  
    try{
    var _appleDates=$.datepicker.formatDate("mm/dd/yy",$.datepicker.parseDate("dd/MM/yy",value));
    return (!/Invalid|NaN/.test(new Date(_appleDates).toString()));
    }catch(e){return false;};
    };

然后按照您的说法使用

rules:{
       eventdate: 
       {
       required:true,   
       date: true
       }
     }

谢谢你快乐!
