Online demo

You can learn more about the parameters of Dynamsoft Barcode Reader by checking out the docs.

Usage

In your HTML, add the component:

<barcode-formats></barcode-formats>
<general-settings></general-settings>
<parameters-modes></parameters-modes>

Load the settings from a JSON template:

window.onload = function() {
  let template = "{\"ImageParameter\":{\"BarcodeFormatIds\":[\"BF_QR_CODE\"],\"Description\":\"\",\"Name\":\"Settings\"},\"Version\":\"3.0\"}";
  let settings = JSON.parse(template);
  const generalSettings = document.querySelector("general-settings");
  const parametersModes = document.querySelector("parameters-modes");
  const barcodeFormats = document.querySelector("barcode-formats");
  generalSettings.loadSettings(settings);
  barcodeFormats.loadSettings(settings.ImageParameter);
  parametersModes.loadSettings(settings.ImageParameter);
}

Output the settings modified with the components:

const generalSettings = document.querySelector("general-settings");
const parametersModes = document.querySelector("parameters-modes");
const barcodeFormats = document.querySelector("barcode-formats");
let settings = await generalSettings.outputSettings();
let formatOutput = await barcodeFormats.outputSettings();
let params = await parametersModes.outputSettings();
for (let key in params) {
  settings.ImageParameter[key] = params[key];
}
settings.ImageParameter.BarcodeFormatIds = formatOutput.BarcodeFormatIds;
settings.ImageParameter.BarcodeFormatIds_2 = formatOutput.BarcodeFormatIds_2;

Monitor changes made:

const updated = () => {
  //Settings are updated.
}
const generalSettings = document.querySelector("general-settings");
const parametersModes = document.querySelector("parameters-modes");
const barcodeFormats = document.querySelector("barcode-formats");
generalSettings.addEventListener("updated",updated);
parametersModes.addEventListener("updated",updated);
barcodeFormats.addEventListener("updated",updated);
