QR Code API example

Javascript example

Create a QR code of the current web page and automatically display it as an image in the page. The Iframe below loads the 'Javascript-API-QR-Code.htm' which automatically uses the API to make a QR code of itself.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" >
    <title>Javascript API QR Code Example</title>
       function getQR(img) {
           var myUrl = document.location.href;
           var imgsrc = "https://www.steeman.org/Gen?key=testkey&type=text&cont=" + encodeURI(myUrl);
           img.src = imgsrc;
<body onload="javascript:getQR(myimage);">
    <img alt="" id="myimage" name="myimage" src="" />
Replace the 'testkey' in the code above with your API key to get rid of the watermark and text under the QR code.
Once you have and use your key, the blue watermark dot in the top left will disappear as will the caption "Created at QR4". The QR4 QR code API is a HTML web request driven QR code generator returning ready to use images for direct attachment to any image object in your web page or desktop application.
