Read Barcodes and Fill Form Fields
It’s difficult to type long text on mobile devices, but if that text is encoded in a barcode, we can use the sdk to read the barcode and automatically enter the text.
The following code shows how to automatically invoke the sdk to read a barcode and fill an input box.
<input id="input-to-fill" type="text" readonly="true" placeholder="Barcode Result">
let scanner = null;
Dynamsoft.DBR.BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
(async function () {
document.getElementById("input-to-fill").addEventListener('click', async function () {
try {
scanner = scanner || await Dynamsoft.DBR.BarcodeScanner.createInstance();
scanner.onUniqueRead = (txt, result) => {
this.value = result.barcodeText;
scanner.hide();
};
await scanner.show();
} catch (ex) {
alert(ex.message);
throw ex;
}
});
})();
The following official sample shows how to use the sdk to fill multiple fields for a form.
