First you need to include the jQuery library, since uQr is a plugin. You can download it from the jQuery website or link it directly from the Google CDN.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
Secondly, you need to include the jQuery uQr javascript file into your page. You can do it by adding the code below to your page.
<script type="text/javascript" src="js/jquery.uqr.js"></script>
Now, you have two possibilities of embedding a QR code.
1. Create the image tag that will be replaced with the QR code image.
<img src="#" id="qr1" alt="" />
For the last part you activate the uQr function on the element you just created, so, we trigger the function on the image with the id qr1.
<script type="text/javascript">
$(document).ready(function() {
$('#qr1').uQr({
type : 'text',
text : 'This is the text to embed'
});
});
</script>
2. Add a div with a specific id to your page, for example :
<div id="qr2"></div>
We trigger the function on the div with the id qr2 AND we add the create: true option, which signals the library to create the image tag inside the container div.
<script type="text/javascript">
$(document).ready(function(){
$('#qr2').uQr({
create : true,
type : 'text',
text : 'This is the text to embed'
});
});
</script>
