javascript in perl code

Question

i using javascript file (json2.js) in perl-cgi code with apache. but when i run it on browser, its unable to find the source and return following error; 'Failed to load resource: the server responded with a status of 404 (Not Found)'

my doumentroot path is : /srv/www/cgi-bin and scripts' path: /srv/www/cgi-bin/scripts

i doing this;

 print "<script type='text/javascript' src='./scripts/json2.js'></script>"; # Line 1
    print "<script type='text/javascript' language='JavaScript'>
    function setDetails(o,json_arrRef,arrSize){
            alert('hello='+arrSize+' || ref='+json_arrRef); // till here it works fine
            var json_obj = JSON.parse(json_arrRef);     
    }
    </script>";

if I edit Line 1 as

print "<script type='javascript' src='./scripts/json2.js'></script>";

it finds the source but gives following error when 'JSON.parse()' is called; 'Uncaught SyntaxError: Unexpected token ILLEGAL'

am I doing something wrong?

Don't put static files anywhere in or below /cgi-bin/ as servers are often configured to treat that path is a special way
Do get your type attributes correct, the content-type for JavaScript is text/javascript and not just javascript (technically speaking it should be application/javascript, but pretend it is text/javascript for the sake of browsers)
Don't compare JavaScript errors in the browser with Perl code and do look at what the webserver is outputting (i.e. the HTML and JavaScript source and/or which requests give 404 or other HTTP error codes)

thanks David, 1. I put the script files on the document root but the result is same. 2. I already tried with these option (application/javascript and text/javascript) but no effects. 3. http 404 was due to Javascript file for sure

ok instead of using JSON.parse() I tried with eval and it is working fine. i downloaded the json2.js from json.org and i don't know why it has a problem. but anyway thanks David

That would be because your JSON is invalid (JSON being a tiny subset of JavaScript). Test it with jsonlint.com

Replace "./scripts/json2.js" with "/scripts/json2.js".
