I am capturing image using canvas and i want to store a captured image in MySQL Database using Javascript.
This is my code:
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, maximum-scale=1.0">
<style>
body {width: 100%;}
canvas {display: none;}
</style>
<title>Instant Camera - Remote</title>
<script>
var video, canvas, msg;
var load = function () {
video = document.getElementById('video');
canvas = document.getElementById('canvas');
msg = document.getElementById('error');
if( navigator.getUserMedia ) {
video.onclick = function () {
var context = canvas.getContext("2d");
context.drawImage(video, 0, 0, 240, 320);
var image1 = canvas.toDataURL("image/png");
document.write('<img src="' + image1 + '" />');
};
} else {
msg.innerHTML = "Native web camera not supported :(";
}
};
window.addEventListener('DOMContentLoaded', load, false);
</script>
</head>
<body>
<video id="video" width="240" height="320" autoplay> </video>
<p id="error">Click on the video to send a snapshot to the receiving screen</p>
<canvas id="canvas" width="240" height="320"> </canvas>
</body>
</html>
getting a canvas “screenshot”, encoding it into a BASE64 string, sending it to a servlet/php/etc and storing it in mysql should work.
