Comment removal

How to remove comments beside variables or function!
How often have you been bitten by a regex? In my work has a lots!
Three days ago, i spent 40 minutes crafting in compressing, do html+css+js to a single file to improve performance of loading from browser.
Here's requirement.

var a="http://ccnhup.com";
// url "" var c='//root//app//test'
 // uri with ' ' var d="http://domain.com";
// //domain var e='//root//app//test'
// // var f=background-image:url(http://domain) // url(://) var g=background-image:url(//domain)  // url(//) var h=(rpc://domain)
 // (rpc://) var i="(", j="("

// variables  with )) // (( ")"   ")" var l=background-image:url(((//domain))) // url(//) var b=function(
   // // function ) var k=1

// k = 1 as eq ///  //

And here's how the story usually goes, this's done by Vu Le.

var a = "[^(http:)(file:)(rpc:)'\"]//[^\n]*\n|[^(http:)(file:)(rpc:)'\"]//[^\n]*$";

Thanks Vu Le for contribution.

var f=background-image:url(http://domain) var g=background-image:url(//domain)
var h=(rpc://domain)
var i="(", j="("
var l=background-image:url(((//domain))) var b=function(
var k=1
