I am fairly new to javascript. The original code of the drawing board run smoothly on the webrowser I test with on my mac, but after I re-edit to fit the mirror, action of drawing does not seem to be working

Hey guys, I am developing a simple module of a drawing board. The board can show on the mirror, but the mouse input cannot draw anything on it. 0_1471672694931_canvas.js

thanks, everything is showing up again, except for the mm-hide-all module, and I don’t see any error on the console. But the button in the module just don’t show up.

thanks, but the whole thing is still black. Nothing’s showing up

Hey guys, I just finish building the mirror and finish setting up all the basics of the magic mirror. The default modules run smoothly. However, whenever I try to run something related to jquery, the mirror just black out. I tired https://github.com/masters1222/mm-hide-all this guy’s module, with the library in it, but there is still nothing on display. I tried inserting source in the index.html, still nothing. And I find that the mirror will work again only if I delete reference to the library of jQuery.
I use a raspbian system and installed the latest MagicMirror2.
