quagga.min.js识别条形码源码
以下是ASP代码，用于在浏览器中直接调用手机摄像头，或者电脑摄像头，直接将识别结果输入到文本框。<script>
// quagga开始扫描
function startScanning1() {
navigator.mediaDevices.getUserMedia({ video: { facingMode: "environment" } })
.then(function (stream) {
var videoElement = document.getElementById("videoElement");
videoElement.srcObject = stream;
videoElement.play();
Quagga.init({
inputStream: {
name: "Live",
type: "LiveStream",
target: videoElement
},
decoder: {
readers: ["ean_reader", "code_128_reader", "code_39_reader"]
}
}, function (err) {
if (err) {
console.error(err);
return;
}
Quagga.start();
});
// 监听扫描结果
Quagga.onDetected(function (result) {
var code = result.codeResult.code;
document.getElementById("barcodeResult").value = code;
stopScanning();
});
})
.catch(function (error) {
console.error("Error accessing camera: ", error);
});
}
// 停止扫描
function stopScanning1() {
Quagga.stop();
var videoElement = document.getElementById("videoElement");
if (videoElement.srcObject) {
videoElement.srcObject.getTracks().forEach(function (track) {
track.stop();
});
videoElement.srcObject = null;
}
}
</script>
