<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Mobile-Web-App: HTML5 Canvas</title>
<script type="text/javascript">
function loadcanvas(){
var canvas;
var context;
//get element by ID of "mycanvas"
canvas = document.getElementById("mycanvas");
//create a "2d" context object
context = canvas.getContext("2d");
drawPath(context);
}
function drawPath(c){
c.strokeStyle = "#ff0000";
c.lineWidth = 10;
c.beginPath();
c.moveTo(0, 0);
c.lineTo(100, 0);
c.lineTo(100, 100);
c.lineTo(0, 100);
c.lineTo(0, 0);
c.stroke();
c.closePath();
c.strokeStyle = "#00ff00";
c.lineWidth = 1;
c.beginPath();
c.moveTo(50, 50);
c.lineTo(250, 50);
c.lineTo(250, 250);
c.lineTo(50, 250);
c.lineTo(50, 50);
c.stroke();
c.closePath();
c.strokeStyle = "#0000ff";
c.lineWidth = 20;
c.beginPath();
c.moveTo(200, 200);
c.lineTo(300, 200);
c.lineTo(300, 300);
c.lineTo(200, 300);
c.lineTo(200, 200);
c.stroke();
c.closePath();
}
