How can I create a dynamic hyperlink with JavaScript?

[Sam97]

I have the following links that I would like to create a dynamic hyperlink in Java to point to current month and year in the hyperlink.

http://www.somesite.com/site_media/u...f_jan_2012.pdf

http://www.somesite.com/site_media/u...f_feb_2012.pdf

http://www.somesite.com/site_media/u...f_mar_2012.pdf

http://www.somesite.com/site_media/u...f_apr_2012.pdf

http://www.somesite.com/site_media/u...f_jan_2013.pdf

The pdf file name within each hyperlink is based on the month and the year.. jan, feb, mar ..etc and for the year 2012 then 2013.

How can I create a dynamic hyperlink that will always display the current month and year?

I appreciate any help.

Thanks

Where possible this is a server-side task.

Insert this where you want the link generated. If JS isn't available, you get nothing:

<script type="text/javascript">

(function( content, title )
{
 var dt = new Date();
 
 document.write( "<a href='http://www.somesite.com/site_media/u...f_" + ['jan','feb','mar','apr','may','jun','jul','aug','sep','oct','nov','dec' ][ dt.getMonth() ] + "_" + dt.getFullYear() + ".pdf' title='" + title +"'>" + content + "<\/a>"); 
})
( "Click me", "Goes to some site" ); /* <-- Link text and link title */

</script>

This is perfect except for one thing I am trying to display reports for the previous month when adding -1 for the getMonth, and if the current month is Jan it will calculate 0 -1 = -1, and it will not display the previous month which is Dec.

Thanks

{
 var dt = new Date();
 
 document.write( "<a href='http://www.somesite.com/site_media/u...f_" + ['jan','feb','mar','apr','may','jun','jul','aug','sep','oct','nov','dec' ][ dt.getMonth() -1 ] + "_" + dt.getFullYear() + ".pdf' title='" + title +"'>" + content + "<\/a>"); 
})
( "Click me", "Goes to some site" ); /* <-- Link text and link title */

</script>

Get the month (and year) of the previous month with:-

<script type="text/javascript">

var months = ['jan','feb','mar','apr','may','jun','jul','aug','sep','oct','nov','dec' ];
var d = new Date();
d.setDate(1);
d.setMonth(d.getMonth() - 1);
var mth = d.getMonth();
var monthname = months[mth];
var yr = d.getFullYear();
alert (mth + "  "  + monthname + "  " + yr);

</script>
