javascript - How to setMonth using month names, and displaying a specific day and year -

question: how can use new date(); object display full month name, day of month, , year time stamp?

function displaylastmod() {     montharray = new array(11);     montharray[0] = "january";     montharray[1] = "february";     montharray[2] = "march";     montharray[3] = "april";     montharray[4] = "may";     montharray[5] = "june";     montharray[6] = "july";     montharray[7] = "august";     montharray[8] = "september";     montharray[9] = "october";     montharray[10] = "november";     montharray[11] = "december";      var thedate = new date();     var themonth = thedate.setmonth(03);     var theday = thedate.setdate(09);     var theyear = thedate.setyear(2015);      document.getelementbyid("lastmodified").innerhtml = "last modified: " +thedate; } 

this code displays "last modified: thu apr 09 2015 18:18:37 gmt-0500 (central daylight time)"

this format need in: "last modified: april 9, 2015 - 6:23:00 pm"

is possible using javascript (without other languages or plugins)?

as know there no function in javascript print formated date.

try this:

function displaylastmod() {     montharray = new array(11);     montharray[0] = "january";     montharray[1] = "february";     montharray[2] = "march";     montharray[3] = "april";     montharray[4] = "may";     montharray[5] = "june";     montharray[6] = "july";     montharray[7] = "august";     montharray[8] = "september";     montharray[9] = "october";     montharray[10] = "november";     montharray[11] = "december";      thedate = new date();thedate.sethours(16);     var themonth = thedate.setmonth(03);     var theday = thedate.setdate(09);     var theyear = thedate.setyear(2015);     var monthname=montharray[thedate.getmonth()]     var day=thedate.getdate();     var year=thedate.getyear()+1900;     var hours=thedate.gethours()     var minutes=thedate.getminutes();     var seconds=thedate.getseconds();     document.getelementbyid("lastmodified").innerhtml = ("last modified: " +monthname+' '+day+', '+year+' - '+hours%12+':'+minutes+':'+seconds+' '+((hours>12)?'pm':'am')); }
