DateTime Modification 2

[cumap]

Hello,

How can I modify hour on this string of date/time

Fri May 1 13:36:48 PDT 2009

I tried getHours() but getting error "object.expected"

Thanks

My goal is to adjust the hour on the string and if there is noway to get the hour to edit, can anyone help me using string functions that somehow pinpoint the hour location so I can come up with a way to replace the hour with more desirable one.

<script type="text/javascript">
var day = new Array();
day[0] = "Sun";
day[1] = "Mon";
day[2] = "Tue";
day[3] = "Wed";
day[4] = "Thu";
day[5] = "Fri";
day[6] = "Sat";

var month = new Array();
month[1] = "Jan";
month[2] = "Feb";
month[3] = "Mar";
month[4] = "Apr";
month[5] = "May";
month[6] = "Jun";
month[7] = "Jul";
month[8] = "Aug";
month[9] = "Sep";
month[10] = "Oct";
month[11] = "Nov";
month[12] = "Dec";

var myDate = new Date("Fri May 11 13:36:48 PDT 2009");
var dayOfWeek = day[myDate.getDay()];
var monthName = month[myDate.getMonth()];
var year = parseInt(myDate.getYear()) + 1900;

var dateDate = myDate.getDate();
var hour = myDate.getHours();
var min = myDate.getMinutes();
var sec = myDate.getSeconds();

var timeOfDay = "AM";
if (parseInt(hour) > 12) {
hour = parseInt(hour) - 12;
timeOfDay = "PM";
}

newDate = dayOfWeek + " " + monthName + " " + dateDate + " " + year + " " + hour + ":" + min + ":" + sec + " " + timeOfDay;
alert(newDate);

^ in the "year" the + 1900 is for FF, as it getYear returns a number equal the the number of years since 1900.

For IE you don't need it, so you'll need to build in a browser check...unless someone else has a better way to grab the year.

BTW a GOOGLE search on "javscript format date" found this - which is probably a MUCH better way of doing this...

The way to grab the full year is with the Date method getFullYear(). That will give you a 4 digit year in all browsers.

Thanks Vicvirk, your code is perfect for my reformat requirement. My bad trying to have this query getHours.strDateTime() to work. Go figure!
