Changing controls to mobile

[Gods]

I am sure everyone who wanted there HTML5 game to work mobile had this problem. So I have my controls set up as space bar to jump but I want my HTML5 game to work everywhere so I need to change it to mouse/touch. Mouse/touch doesnt have a keycode so whats the most optimal way to do it for this code? Do I need to do mouse and touch separately?
 

if (KEY_STATUS.space && player.dy === 0 && !player.isJumping) {  player.isJumping = true;  player.dy = player.jumpDy;  jumpCounter = 12;  assetLoader.sounds.jump.play();}// jump higher if the space bar is continually pressedif (KEY_STATUS.space && jumpCounter) {  player.dy = player.jumpDy;}

I have read a lot of tutorials on this and it seems like its going to be a lot of code I just want to know what html5 devs do so I dont write bad JS code. Its not a simple KeyCode for mouse or something. So how does this code snippet look like if Jump is set to mouse/touch? Anyone have code they can share?
