Hi.

 

I am new here and new to javascript :) Can som one help me to understands some codes?

 

 

if ((p=n.indexOf("?")) > 0 && parent.frames.length)

 

if (a[i+1].charAt(0)=="#"

 

See the attached file for details.

 

1. What means by question mark # and a number sign # in if statments above?

 

2. I want to remove check on first field mamed "Elevnummer" and from radio option.

 

3. How can I output the values of the objects

 

thanks :)

No, it's literally looking for a "?" or "#" in the string. I haven't read the full source code, but I assume it's looking for the query string and hash in the URL. These are the parts of a URL:http://www.example.com/path/file.html?a=1#extra-dataProtocol Host name URI query string hash The query string always starts with a "?" and the hash always starts with "#"
