JavaScript - Convert Sample To S A M P L E

I have come to the conclusion that this book title sux "New Perspectives on JavaScript, 2nd Edition " Is there a better book I can use where I can copy the sample programs that the book uses, that actually has good modern javascript technique, and has the other code that goes along with it like the html, the css, and the .jpgs all on the cd that comes with the book or something? "Professional JavaScript for Web Developers (Wrox Programmer to Programmer)" by Nicholas C. Zakas is a good book title it definitely clarified that crappy text book that my university gave me, but I'm ready to take the next step and start using sample code and apply the concepts I learned from that book. Please recommend anything I would need to be ubber programmers like all of you guys.

I have strings's that are causing problems when being sent to a PHP script via JavaScript. (not all of it is getting sent)

i.e.

This is someone's line of text & it's rather long.

I wish to convert the whole string to some other format say like the spaces to %20 and and the & to & I think, and so on...

Then once the PHP script $_GET's the string it converts it back to the original.

PLEASE NOTE: I wish to use JavaScript, not JQuery.

See title

How do i do it?

Any one can help how to convert the below PHP code to javascript code:
class Mobile {
public static function is_mobile(){
$user_agent = $_SERVER['HTTP_USER_AGENT']; // get the user agent value - this should be cleaned to ensure no nefarious input gets executed
$accept = $_SERVER['HTTP_ACCEPT']; // get the content accept value - this should be cleaned to ensure no nefarious input gets executed
return false

How do I do this equivalent function in javascript?
Code:

int x = 0;
int y = 1; 

convertBool(x);
convertBool(y);

private void convertBool(obj)
{
  bool rtnB = Convert.ToBoolean(obj);
  string TorF = (!obj) ? "true" : "false" ;
  Console.WriteLine(TorF);
} 

// code would output
// false
// true

I am trying to pass a bit by my function call
Code:

function fxn(obj){
  document.getElementById('box').style.display = (!obj) 'block' : 'none' ;
}

code somewhere else...
onmouseover="fxn(1);" onmouseout="fxn(0)"

I know I could do it via if obj != 0 or if obj == 0 but I want to be able to convert the bool- I know how to do it other ways but if js does not support a "one liner" I will do it via int compare
