Share a JS function that converts a string of the specified date format to a date todate

Today found Easyui Datetimebox can not display the normal date, and then nature is to realize the function of ToDate, Google, did not find satisfaction, are written very wordy. Write your own, originally thought JS can also be used to name group, but the current look at JavaScript does not seem to support. Now implement the code below and hope to be helpful to those who need it.

by Dragonimp 2015.5.3//use://"2015-5-5 9:10:10". ToDate ("yyyy-m-d hh:mm:ss")//"2015/5/5 9:10:10". ToDate ("yyyy/m/d Hh:mm:ss ") String.prototype.toDate = function (FMT) {    if (FMT = = null) FMT = ' Yyyy-mm-dd hh:mm:ss ';    var str = this;    FMT is a date format, str is a date string    var reg =/([ymdhmss]+)/g;//the characters in the date format    var key = {};    var Tmpkeys = Fmt.match (reg);    for (var i = 0; i < tmpkeys.length; i++) {        key[tmpkeys[i].substr (0, 1)] = i + 1;    }    var r = Str.match (Fmt.replace (Reg, "(\\d+)"));    return new Date (r[key["y"], r[key["M"]]-1, r[key["D"]], r[key["H"]], r[key["M"]], r[key["s"]], r[key["s"]);}

Attached: Easyui problems and solutions.

Problem:

<input type= "text" value= "2015/5/6 23:00:00" id= "xxxx" class= "Easyui-datetimebox"/>
this displayed control, the date "Day" section is displayed incorrectly, and the date of the day is displayed.

Check the following, Easyui has quoted the Chinese resource file, looked under the resource file, should only support "-" split the date, I am here "/"

Solution: You need to implement formatter and parser yourself.

1. Add Options

<input type= "text" value= "2015/5/6 23:00:00" id= "xxxx" class= "Easyui-datetimebox" data-options= "Formatter: Datetimebox_format,parser:datetimebox_parse "/>

2. Implementation of parsing and formatting functions

function Datetimebox_format (date) {return date.toformatstring ("yyyy/m/d h:mm:ss");}  function Datetimebox_parse (s) {return s.todate ("yyyy/m/d hh:mm:ss"); }//a) Turn the date, see preceding my todate//b) to the string below, from the online Date.prototype.toFormatString = function (fmt) {var o = {"m+": This.get                   Month () + 1,//month "d+": this.getdate (),//day "H +": this.gethours (), Hours "m+": this.getminutes (),//min "s+": This.getseconds (),/    /sec "q+": Math.floor ((This.getmonth () + 3)/3),//Quarterly "S": this.getmilliseconds ()//msec};    if (/(y+)/.test (FMT)) FMT = Fmt.replace (regexp.$1, (this.getfullyear () + ""). substr (4-regexp.$1.length));  For (var k in O) if (New RegExp ("(" + K + ")"). Test (FMT)) FMT = Fmt.replace (regexp.$1, (regexp.$1.length = = 1)?    (O[k]): (("XX" + o[k]). substr (("" + O[k]).)); return FMT;}
