RGB颜色转HEX进制与单位换算

RGB颜色转HEX进制：

function rgbToHex(R,G,B) {return toHex(R)+toHex(G)+toHex(B)}
 function toHex(N) {
  if (N==null) return "00";
  N=parseInt(N); if (N==0 || isNaN(N)) return "00";

  return "0123456789ABCDEF".charAt((N-N%16)/16)
       + "0123456789ABCDEF".charAt(N%16);
 }function getColorStringFromRGB(r, g, b) {
     return "#" + toHex(r) + toHex(g) + toHex(b);
