dRawr is a JQuery plugin that can transform any canvas component (with a container) into a drawing area. It's developed for iOS, Android, and most desktop browsers.
The only requirement at the moment is material design icons.
//Code for Example 1 html <div style="width:350px;height:300px;border:2px dotted gray;margin:20px;"> <canvas id="canvas1"></canvas> </div> js //Turn a canvas element into a sketch area $("#canvas1").drawr({ "enable_transparency" : false, "canvas_width" : 1200, "canvas_height" : 1200 }); //Enable drawing mode, show controls $("#canvas1").drawr("start"); function destroy(){ $("#canvas1").drawr("destroy"); } function clear(){ $("#canvas1").drawr("clear"); } }More examples included in the package from github.
