Returning the name of the month

I have a snippet of code for creating a “Date Picker” that has an image of a calendar and you just choose the appropriate date and it fills in the form accordingly. The code works fine except that it returns a number for the month field and I need a month name (i.e. JAN, FEB, MAR, etc.) Here is the code:

<script language=”javascript”>

var thisPage = “ship_info_calendar.html”;
var formName = “ship_info”;
var field_name = “begin_date”;

monthsNames = Array( “”, “January”, “February”, “March”, “April”, “May”, “June”, “July”, “August”, “September”, “October”, “November”, “December” );

var tempString = location.search.substring( 1 );
if ( tempString.indexOf( “&” ) != -1 ) {
var temp1 = tempString.split( “&” );
var strField = temp1[ 0 ];
var temp2 = temp1[ 1 ];
var strData = temp2.split( “,” );
} else {
var strField = tempString;
var strData = tempString.split( “,” );
}

var strMonth = parseInt( strData[ 0 ], 10 );
var strYear = parseInt( strData[ 1 ], 10 );

var dateObject = new Date();
var thisMonth = dateObject.getMonth();
var thisYear = dateObject.getFullYear();
var curMonth = dateObject.getMonth();
var curDay = dateObject.getDate();
var curYear = dateObject.getFullYear();

if (( strMonth > 0 ) || ( strYear > 0 )) {
curMonth = strMonth;
curYear = strYear;
}

var today = new Date( curYear, curMonth, 1 );
var today = today.getDay();

function daysPerMonth( month, year ) {
days = 31;
if (( month == 4 )||( month == 6 )||( month == 9 )||( month == 11 )) {
days = 30;
} else if ( month == 2 ) {
if (((( year % 100 ) == 0 ) && (( year % 400 ) == 0 )) || ((( year % 100 )!=0 ) && (( year % 4 ) == 0 ))) {
days = 29;
} else {
days = 28;
}
}
return days;
}

function monthBack( month, year ) {
if ( month == 0 ) {
location.href = thisPage + “?” + strField + “&” + 11 + “,” + ( year – 1 );
} else {
location.href = thisPage + “?” + strField + “&” + ( month – 1 ) + “,” + year;
}
}

function monthForward( month, year ) {
if ( month == 11 ) {
location.href = thisPage + “?” + strField + “&” + “0” + “,” + ( year + 1 );
} else {
location.href = thisPage + “?” + strField + “&” + ( month + 1 ) + “,” + year;
}
}

function yearBack( month, year ) {
location.href = thisPage + “?” + strField + “&” + ( month ) + “,” + ( year – 1 );
}

function yearForward( month, year ) {
location.href = thisPage + “?” + strField + “&” + ( month ) + “,” + ( year + 1 );
}

function getYear( year ) {
retval = new String( year );
<!– –>retval = retval.slice( 2, 4 );
return retval;
}

function getMonth( month ) {
month++;
retval = new String( month );
<!– –>if ( retval < 10 ) {
<!– –>retval = “0” + retval;
switch(retval)
{
case ( retval = 1 ):
retval = “JAN”
break
case ( retval = 2 ):
retval = “FEB”;
break
case ( retval = 3 ):
retval = “MAR”;
break
case ( retval = 4 ):
retval = “APR”;
break
case ( retval = 5 ):
retval = “MAY”;
break
case ( retval = 6 ):
retval = “JUN”;
break
case ( retval = 7 ):
retval = “JUL”;
break
case ( retval = 8 ):
retval = “AUG”;
break
case ( retval = 9 ):
retval = “SEP”;
case ( retval = 10 ):
retval = “OCT”;
break
case ( retval = 11 ):
retval = “NOV”;
break
case ( retval = 12 ):
retval = “DEC”;
break
}
return retval;
}

function getDay( day ) {
retval = new String( day );
if ( retval < 10 ) {
retval = “0” + retval;
}
return retval;
}

function createCSS() {
var cssStyle = “”;
cssStyle = cssStyle + “”;
cssStyle = cssStyle + “<style type=text/css>”;
cssStyle = cssStyle + “A:link { COLOR:#101010;TEXT-DECORATION:none; }”;
cssStyle = cssStyle + “A:visited { COLOR:#101010;TEXT-DECORATION:none; }”;
cssStyle = cssStyle + “A:active { COLOR:#101010;TEXT-DECORATION:none; }”;
cssStyle = cssStyle + “A:hover { COLOR: #101010;TEXT-DECORATION:none; }”;
cssStyle = cssStyle + “.Numeric { FONT-FAMILY:Verdana,Arial,Helvetica;FONT-SIZE:10px;LINE-HEIGHT:16px; }”;
cssStyle = cssStyle + “.DaysLabel { FONT-FAMILY:Verdana,Arial,Helvetica;FONT-SIZE:11px;LINE-HEIGHT:16px;COLOR:#FF0000; }”;
cssStyle = cssStyle + “.TextLabel { FONT-FAMILY:Verdana,Arial,Helvetica;FONT-SIZE:12px;LINE-HEIGHT:16px; }”;
cssStyle = cssStyle + “</style>rn”;
return cssStyle;
}

…I attempted to place a case to return the name of the month based on the “retval” but now all I get is the number “12”?
