I want to add image in javascript

Question

i want to add image using javascript but it is not working

html code:

<body onload="init()">
    <canvas id="canvas" width="640" height="480">
        <p>your browser doesnot support html5 canvas.</p>
    </canvas>
    <script src="script.js">
    </script>
</body>

and this is javascript:

var canvas;
var context;

function init() {
    canvas = document.getElementById("canvas")
    context = canvas.getContext("2d");
    console.log("loading comepletd");
    var image = new Image();
    image.src = "ball.png";
}

What exactly are you expecting to happen? You're creating an instance of an image but you aren't doing anything with it. — Mike Cluck, Aug 29 '16 at 14:41
you forgot a semi-colon after the getElementById() And you can you the JS console to debug your code ;) (F12) — Pierre, Aug 29 '16 at 14:42
i want to show this image in my browser. That's all i want to do! — suzan, Aug 29 '16 at 14:43
The phrase: "Not working" is going to invite downvotes. We are not mind-readers. Tell us what you expected to happen and what actually happened. — Eric Leschinski, Aug 29 '16 at 14:43
@Pierre Technically the semicolon isn't required but it's definitely a good idea to be consistent. — Mike Cluck, Aug 29 '16 at 14:43
@suzan If all you want is to show an image in your browser then you can just do `` but based on your code, it looks like you're trying to make a game or animation. — Mike Cluck, Aug 29 '16 at 14:44

Try this

var canvas;
var context;

function init() {
    canvas = document.getElementById("canvas");
    context = canvas.getContext("2d");
    console.log("loading comepletd");
    var image = new Image();
    image.src = "ball.png";
    image.onload = function(){
        context.drawImage(image, 100, 100);
    }
}
