如何检测用户的区域设置日期和时间格式 [英] How to detect the user's locale date and time format

问题描述

有没有可能使用纯粹的Javascript来确定用户在他的操作系统（Windows，Linux，MAC OS等）上配置的日期时间 FORMAT ？

Is there a possibility to determine, with pure Javascript, what date time FORMAT has user configured on his operating system (Windows, Linux, MAC OS, etc.)?

提前感谢

编辑：我知道方法toLocaleString（），但这并不能帮助我得到<

I know about the method toLocaleString(), but this isn't help me to get the format that client has configured on his local machine.

推荐答案

我写了一些纯粹的javascript，它的作品在IE / Firefox / Chrome。它将放出MM / DD / YYYY或DD / MM / YYYY，取决于toLocalDateString（）。

I wrote something in pure javascript that works in IE/Firefox/Chrome. It will out put MM/DD/YYYY or DD/MM/YYYY,... depending in toLocalDateString().

没有在Safari上工作，但新的Date（） .toLocalDateString（）也没有。

Did not work on Safari but new Date().toLocalDateString() did not either.

这是一个 jsFiddle

 //Create a known date string
var y = new Date(2013, 9, 25);
var lds = y.toLocaleDateString();

//search for the position of the year, day, and month
var yPosi = lds.search("2013");
var dPosi = lds.search("25");
var mPosi = lds.search("10");

//Sometimes the month is displayed by the month name so guess where it is
if(mPosi == -1)
{
    mPosi = lds.search("9");
    if(mPosi == -1)
    {
        //if the year and day are not first then maybe month is first
        if(yPosi != 0 && dPosi != 0)
        {
            mPosi = 0;
        }
        //if year and day are not last then maybe month is last
        else if((yPosi+4 <  lds.length) && (dPosi+2 < lds.length)){
            mPosi = Infinity;
        }
        //otherwist is in the middle
        else  if(yPosi < dPosi){
            mPosi = ((dPosi - yPosi)/2) + yPosi;            
        }else if(dPosi < yPosi){
            mPosi = ((yPosi - dPosi)/2) + dPosi;
        }   
    }

}


var formatString="";
var order = [yPosi, dPosi, mPosi];
order.sort(function(a,b){return a-b});

for(i=0; i < order.length; i++)
{
    if(order[i] == yPosi)
    {
        formatString += "YYYY/";
    }else if(order[i] == dPosi){
        formatString += "DD/";
    }else if(order[i] == mPosi){
        formatString += "MM/";
    }
}

formatString = formatString.substring(0, formatString.length-1);

$('#timeformat').html(formatString+" "+lds);
