[mapserver-users] Templates and javascript

[Armin Burger]

Steve,
The document.write() should take the sub-array at position 4 out of the main
array and from this sub-array take the string at position indicated by
thelanguage. When I use gFldString[thelanguage] the whole sub-array at
position 'thelanguage' is printed.

When I try another definition of the array with
   var aGem = new Array('[GEMD]', '[GEMI]', '[GEMI]');
and then
   <td><script
language=JavaScript1.2>document.write(aGem[thelanguage]);</script>
then the results are the same: the field name taken as string from the array
instead of the field value is printed.

I don't know if that is  a special behaviour of javascript. I was thinking a
string is a string, no matter if you take it out of an array or if you give
it directly.

Another problem with bi/multi-lingual applications is the map file. I'd had
to change too many map file values for class names, label fields, etc. to
include that in the url. I see following possibilities
* a map file for every language: causing redundancy but the easiest way
* creating the map file on the fly (with perl or php): don't know how to
access this map file. Any sample sites?
* using mapscript: means a complete new application.
Any other suggestions?

Thanks
Armin
