here html: 

<!doctype html> <html> <head> <script src="popup.js"> </script> </head> <canvas id="canvs" style="border: 2px solid black"></canvas>     <input type = "button" value = "color" onclick="colorchange()"> </html>

javascript (popup.js): 

function colorchange(){     var can = document.getelementbyid("canvs");     can.style.backgroundcolor = "green"; }

any appreciated, thanks!

chrome extension not support inline javascript

you should 

<input id="color" type = "button" value = "color" > 

$("#color").click(function(){  	// code  });

// popup.js  window.onload= function(){  	var color = document.getelementbyid("color");  	color.onclick = function(){  		// code  	}  }
