JS Date format Conversion method

JS Date format Conversion method

1. Convert the date to the specified format: for example, when you convert to a month or day, this format: Yyyy-mm-dd hh:mm:ss or YYYY-MM-DD. Of course the method is online, just summarized below.

You can add the following method to the date prototype:

Date.prototype.format =function(FMT) {varo = {         "m+": This. GetMonth () +1,//Month"D+": This. GetDate (),//Day"H +": This. GetHours (),//hours"m+": This. getminutes (),//points"S+": This. getseconds (),//seconds"q+": Math.floor (( This. GetMonth () +3)/3),//Quarterly "S": This. Getmilliseconds ()//milliseconds    }; if(/(y+)/. Test (FMT)) {FMT=fmt.replace (Regexp.$1, ( This. getFullYear () + ""). substr (4-regexp.$1. length)); }      for(varKincho) {if(NewRegExp ("(" + K + ")"). Test (FMT)) {FMT= Fmt.replace (regexp.$1, (regexp.$1.length==1)? (O[k]): (("XX" + o[k]). substr ("" +o[k])); }     }    returnFMT;} 

For example, we can invoke the following:

var time1 = new Date (). Format ("Yyyy-mm-dd hh:mm:ss");
Console.log (TIME1);
