Hi.

JSON library makes it possible.

For example:  
[http://flori.github.com/json/](http://flori.github.com/json/)

Usage:  
puts %w!foo bar baz!.to\_json

I tried using json but I am doing some mistake because of which I am not  
able to get value properly  
I have such code in ruby file  
@files = Dir.glob("\*.txt").to\_json  
In view file  
var files= (’\<%= h @kmlfiles -%\>’);  
When I see the alert I get a complete string containing list of all  
files  
When I run this alert I see one character printed at a time iso a single  
file name.  
for(i=0;i\<3;i++)  
{  
alert(files[i]);  
}

I am making some mistake in using json but could not figure out what.  
Can you please help ?
