我尝试对datepicker进行本地化，但是我无法弄清楚这段代码的作用。
代码是：
this._datepickerShowing=!1,this._inDialog=!1,this._mainDivId="ui-datepicker-div",this._inlineClass="ui-datepicker-inline",this._appendClass="ui-datepicker-append",this._triggerClass="ui-datepicker-trigger",this._dialogClass="ui-datepicker-dialog",this._disableClass="ui-datepicker-disabled",this._unselectableClass="ui-datepicker-unselectable",this._currentClass="ui-datepicker-current-day",this._dayOverClass="ui-datepicker-days-cell-over",this.regional=[],this.regional[""]={closeText:"Done",prevText:"Prev",nextText:"Next",currentText:"Today",monthNames:["January","February","March","April","May","June","July","August","September","October","November","December"],monthNamesShort:["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"],dayNames:["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"],dayNamesShort:["Sun","Mon","Tue","Wed","Thu","Fri","Sat"],dayNamesMin:["Su","Mo","Tu","We","Th","Fr","Sa"],weekHeader:"Wk",dateFormat:"mm/dd/yy",firstDay:0,isRTL:!1,showMonthAfterYear:!1,yearSuffix:""},
我需要像这样本地化monthNames和dayNamesMin：
this.regional [“ en”] = {monthNames：[“ January”，“ February”，“ March”，“ April”，“ May”，“ June”，“ July”，“ August” ，“ 9月”，“ 10月”，“ 11月”，“ 12月”]，dayNamesMin：[“ Su”，“ Mo”，“ Tu”，“ We”，“ Th”，“ Fr”，“ Sa”]}
和
this.regional [“ cs”] = {monthNames：[“ Leden”，“Únor”，“Březen”，“ Duben”，“Květen”，“Červen”，“Červenec”，“ Srpen” ，“Září”，“Říjen”，“ Listopad”，“ Prosinec”]，dayNamesMin：[“ Ne”，“ Po”，“Út”，“ St”，“Čt”，“Pá”，“ So”]}
但是当我输入“ en或cs”时，我立即得到错误。有什么建议吗？
