$(document) .ready (function () {

Var canvas=document.getElementById ("draw")

Var draw=canvas.getContext ("2d")

Draw.lineWidth=5; / / Line thickness

Draw.strokeStyle= "red"; / / Color

Var godraw=false

/ / Press the mouse

$("# draw") .mousedown (function (e) {

/ / exact coordinates

Var mouseX=e.pageX-this.offsetLeft

Var mouseY=e.pageY-this.offsetTop

Draw.moveTo (mouseX,mouseY)

Godraw=true

})

/ / release the mouse

$("# draw") .mouseup (function (e) {

Godraw=false

})

/ / move the mouse

$("# draw") .mousemove (function (e) {

If (godraw) {

Var mouseX=e.pageX-this.offsetLeft
