Convert rgb strings to hex in Javascript

Question

I am using the TweenMax JS library with the ColorPropsPlugin which will tween color values which are specified in many formats, the problem I have is that the result is always i

Answer 1

This is what I did.

String.prototype.toRGB = function() {

  var rgb = this.split( ',' ) ;
  this.r=parseInt( rgb[0].substring(4) ) ; // skip rgb(
  this.g=parseInt( rgb[1] ) ; // this is just g
  this.b=parseInt( rgb[2] ) ; // parseInt scraps trailing )

}

After you run 'rgb(125,181,215)'.toRGB(), you will get .r, .g and .b properties defined (with correct integer values) in the same string object returned.

To get the hex value, simply use yourNumber.toString(16);
