The playinline attribute,if true tells the ios browser to not set the camera if full screen. This means that if the user is using a mobile device, this will attempt to use the back camera. The getUserMedia function takes an object as a parameter, which we’re passing the video object with the facingMode set to "environment". Output.innerHTML = `Sorry, Your Browser Cannot support this feature` Next, we add the following block of code to the bottom qrcodeii.callback = ( res) => ) We then grab the other elements to display the results of the scan. This is needed to draw the images on the canvas section we created The fourth line gets the canvas element and assigns the 2d context to a constant. The third line creates a video element to handle images coming from the video The second line catches the QR code icon in the HTML to be used for an onclick function to run the whole process of activating the camera.

Let scanIcon = document.querySelector( "#scan") Ĭonst video = document.createElement( "video") Ĭonst canvasElement = document.getElementById( "canvas") Ĭonst canvas = canvasElement.getContext( "2d") Ĭonst qrResult = document.getElementById( "result") Ĭonst outputData = document.getElementById( "output") Įxplaining the code, the first line fetches the QRcode object from the windows and assigns it to a variable to be used later. Lets write some code in our file let qrCode = window.qrcode Īnd this for your qr code iconify to show CREATE JS FILE Make sure you include this script tag at the bottom of your code before your tag. The next step is to add basic styling by creating your style.css file CREATE CSS FILE html,īox-shadow: 0 8px 16px 0 rgb( 0 0 0 / 20%) įirst off,remember that library we talked about? We will need it about now. This block is for creating the canvas section on which the camera will be displayed on and the corresponding data received after the code has been scanned. Right underneath your block of code write this too. This block of code is just for visual enhancement and styling. What we need is a js library capable of interpreting QR code so let's get to it.įirst, we will need to create our HTML file index.html CREATE HTML FILE I had to go through a lot of trouble though, deep searching to find the code so this article here is to lessen the search in case there is someone out there facing similar issues. It is one of the fastest ways options to use for the web. Months ago, while building a web-based project and this particular section needed a QR code scanner to implement.Ībout 2015 or so, this would have been not possible because that is a feature only native apps possessed, but thanks to the beauty of evolving JavaScript, we now have the power in our hands💪.
