title: Background-color hex to JavaScript variable
body: <p>I'm kind of new to JavaScript and jQuery and now I'm facing a problem:</p>
  
  <p>I need to post some data to PHP and one bit of the data needs to be the background color hex of div X.</p>
  
  <p>jQuery has the css("background-color") function and with it I can get RGB value of the background into a JavaScript variable.</p>
  
  <p>The CSS function seems to return a string like this rgb(0, 70, 255). </p>
  
  <p>I couldn't find any way to get hex of the background-color (even though it's set as hex in CSS).</p>
  
  <p>So it seems like I need to convert it. I found a function for converting RGB to hex, but it needs to be called with three different variables, r, g and b. So I would need to parse the string rgb(x,xx,xxx) into var r=x; var g=xx; var b=xxx; somehow. </p>
  
  <p>I tried to google parsing strings with JavaScript, but I didn't really understand the regular expressions thing. </p>
  
  <p>Is there a way to get the background-color of div as hex, or can the string be converted into 3 different variables?</p>
