扩展JavaScript的Date.parse以允许DD/MM/YYYY(非美国格式的日期)？

Question

我想出了这个解决方案来扩展JavaScript的Date.parse功能,允许日期格式为DD/MM/YYYY(而不是美国标准[和默认] MM/DD/YYYY):

(function() {
    var fDateParse = Date.parse;

    Date.parse = function(sDateString) {
        var a_sLanguage = ['en','en-us'],
            a_sMatches = null,
            sCurrentLanguage,
            dReturn = null,
            i
        ;

            //#### Traverse the a_sLanguages (as reported by the browser)
        for (i = 0; i < a_sLanguage.length; i++) {
                //#### Collect the .toLowerCase'd sCurrentLanguage for this loop
            sCurrentLanguage = (a_sLanguage[i] + '').toLowerCase();

                //#### If this is the first English definition
            if (sCurrentLanguage.indexOf('en') == 0) {
                    //#### If this is a definition for a non-American based English (meaning dates are "DD MM YYYY")
                if (sCurrentLanguage.indexOf('en-us') == -1 &&      // en-us = English (United States) + Palau, Micronesia
                    sCurrentLanguage.indexOf('en-ca') == -1 &&      // en-ca = English (Canada)
                    sCurrentLanguage.indexOf('en-ph') == -1 &&      // en-ph = English (Philippians)
                    sCurrentLanguage.indexOf('en-bz') == -1         // en-bz = English (Belize)
                ) {
                        //#### Setup a oRegEx to locate "## ## ####" (allowing for any sort of delimiter except a '\n') then collect the a_sMatches from the passed sDateString
                    var oRegEx = new RegExp("(([0-9]{2}|[0-9]{1})[^0-9]*?([0-9]{2}|[0-9]{1})[^0-9]*?([0-9]{4}))", "i");
                    a_sMatches = oRegEx.exec(sDateString);
                }

                    //#### Fall from the loop (as we've found the first English definition)
                break;
            }
        }

            //#### If we were able to find a_sMatches for a non-American English "DD MM YYYY" formatted date
        if (a_sMatches != null) {
            var oRegEx = new RegExp(a_sMatches[0], "i");
                //#### .parse the sDateString via the normal Date.parse function, but replacing the "DD?MM?YYYY" with "YYYY/MM/DD" beforehand
                //####     NOTE: a_sMatches[0]=[Default]; a_sMatches[1]=DD?MM?YYYY; a_sMatches[2]=DD; a_sMatches[3]=MM; a_sMatches[4]=YYYY
            dReturn = fDateParse(sDateString.replace(oRegEx, a_sMatches[4] + "/" + a_sMatches[3] + "/" + a_sMatches[2]));
        }
            //#### Else .parse the sDateString via the normal Date.parse function
        else {
            dReturn = fDateParse(sDateString);
        }

            //#### 
        return dReturn;
    }
})();

在我的实际(dotNet)代码中,我通过以下方式收集a_sLanguage数组:

a_sLanguage = '<% Response.Write(Request.ServerVariables["HTTP_ACCEPT_LANGUAGE"]); %>'.split(',');

现在,我不确定我找到"us-en"等的方法.是最合适的.几乎只有美国和当前/前美国影响的地区(帕劳,密克罗尼西亚,菲律宾)+伯利兹和加拿大使用时髦的MM/DD/YYYY格式(我是美国人,所以我可以称之为funky =).因此,如果Locale不是"en-us"/ etc,那么可以正确地争辩说.首先,应该使用DD/MM/YYYY.思考？

作为一个旁注......我在PERL中"长大"但是自从我在RegEx中做了很多繁重的工作以来,这一直都很小.这个表达对每个人都是正确的吗？

这似乎是很多工作,但根据我的研究,这确实是关于在JavaScript中启用DD/MM/YYYY日期的最佳方式.有更轻松/更好的方式吗？

PS-在提交之前重新阅读这篇文章...我已经意识到这更像是"你可以编码审查这个"而不是一个问题(或者问题中嵌入了一个答案).当我开始写这篇文章时,我不打算在这里结束=)

我会使用Datejs.您可以直接加载适合给定ISO语言代码的版本(例如date-en-CA.js或date-en-GB.js).只有资本化是不同的.
