<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.5.0/Chart.min.js"></script>
</head>
<body>
<canvas id="myChart"></canvas>
<script>
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'line',
data: {
labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
datasets: [{
label: 'My First Dataset',
data: [65, 59, 80, 81, 56, 55, 40],
fill: false,
borderColor: 'rgb(75, 192, 192)',
tension: 0.1
}]
},
options: {}
});
</script>
</body>
</html>- Game development:
Canvas JS can also be used for game development to achieve richness by drawing various graphic elements and animation effects Various game interactions. The following is a simple sample code for a small game:
<!DOCTYPE html>
<html>
<head>
<style>
canvas {
border: 1px solid black;
}
</style>
</head>
<body>
<canvas id="myCanvas" width="480" height="320"></canvas>
<script>
var canvas = document.getElementById("myCanvas");
var ctx = canvas.getContext("2d");
var x = canvas.width / 2;
var y = canvas.height - 30;
function drawBall() {
ctx.beginPath();
ctx.arc(x, y, 10, 0, Math.PI*2);
ctx.fillStyle = "#0095DD";
ctx.fill();
ctx.closePath();
}
function draw() {
ctx.clearRect(0, 0, canvas.width, canvas.height);
drawBall();
x += 2;
y -= 2;
}
setInterval(draw, 10);
</script>
</body>
</html>3. Summary
By exploring the technical application of Canvas JS, we can see its huge potential in fields such as web design and game development. potential. Through the rich functions and high-performance drawing of Canvas JS, we can achieve various complex drawing effects and game interactions to meet the growing needs of users. We hope that the code examples in this article can help readers better understand and apply Canvas JS technology, speed up the project development process, and achieve creative breakthroughs.
