qr-code

Generating a Simple QR-Code with just HTML

I came across this APIserver to generate the QRCode but I was wondering is it possible to just use HTML to generate the QRcode for example this is what I was thinking

<input id="text" type="text" value="Please Enter Your NRIC or Work Permit" style="Width:20%"/> 
         
<img src="https://api.qrserver.com/v1/create-qr-code/?data=HelloWorld&amp;size=100x100" alt="" title="HELLO" />

In the "title" I believe it is where you will write your text and the QR code would generate, I was wondering how can I create a text box for me to key in the value directly on a website.

Solution

  • Were you thinking of something like this? https://jsfiddle.net/v7d6d1ps/

    Your HTML can be similar to what you have but with added onblur event. Only HTML cannot do this, so I have added jQuery/JavaScript combination.

    function generateBarCode() {
  var nric = $('#text').val();
  var url = 'https://api.qrserver.com/v1/create-qr-code/?data=' + nric + '&amp;size=50x50';
  $('#barcode').attr('src', url);
}
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

<input id="text" type="text" value="NRIC or Work Permit" style="Width:20%" onblur='generateBarCode();' />

<img id='barcode' src="https://api.qrserver.com/v1/create-qr-code/?data=HelloWorld&amp;size=100x100" alt="" title="HELLO" width="50" height="50" />

    Copy and paste this into an HTML file on your desktop. Type in the text box 12345 and hit tab. Notice that the QR code will update.
