JavaScript jQuery Basics (2014) Creating a Simple Drawing Application Perfect

Expanding on the drawing application

Hi everyone. I've completed the "Creating A Simple Drawing Application" in the jQuery basics section. It was a lot of fun so I decided to expand on the project.

I successfully included a slider to change the width of the "brush"

Now I'm wondering if there is any way I can reformat this for mobile. It seems as though the mouse functions used in the jQuery script won't work for iOS or Android. I've searched this topic but I couldn't find anything that seemed relevant to this case.

I uploaded my code to codepen if anyone wants to take a look http://codepen.io/seanpierce/pen/yYpdOw

If anyone can help point me in the right direction I would really appreciate it. Thanks!

Your CodePen link doesn't seem to be working for me, so I'll try to give some general pointers that you can investigate.

I believe you could use the vmousedown, vmouseup, and vmousemove events from jQuery Mobile. You can find documentation for those methods here. If you want to test this, you can get started quickly without having to download anything by using Google's CDN.

Let me know if you run into any snags, and I'll do my best to help work them out. Happy coding! :)

Thanks rydavim! I'll look at this right now. I'm not sure why the link doesn't work. Here is another one http://codepen.io/seanpierce/full/yYpdOw/

I appreciate your help!

Looks like the CodePen links work if you take the &#13 off the end.

The touch addition looks like it's a bit more complicated than I originally thought. I've got to go to work, but I'll investigate more later today and get back to you.

There is a really informative article on Zipso working with a very similar example. I would highly recommend taking a look if you get stuck in your tinkering.

Happy coding! :)
