How do I make part of a style element a function? (IE: color:$random instead of color:red)

Tags: javascript,html,css

Problem :

This is probably a really noob question, but I couldn't figure out on my own thus far.. The title pretty much covers it up but I'm looking for how I can change the element some CSS into a function, in this case random.

To rephrase and provide more of a picture for you I want the program I am working on to look like this:

<p onClick="document.Color='$randomColor'"> Test sentence. </p>

as opposed to what I have now.

<p onClick="document.Color='green'"> Test sentence. </p>

Can anyone please help me? Many thanks in advance if anyone can!

Solution :

function getRandomColor()
var r = Math.floor(Math.random()*256);
var g = Math.floor(Math.random()*256);
var b = Math.floor(Math.random()*256);
return r.toString(16)+g.toString(16)+b.toString(16);
<body id="bd">
<p onclick="document.getElementById('bd').style.color='#'+getRandomColor();"> Test sentence. </p>
