This error usually occurs when the `qrcode` function from the jQuery QR Code library is not properly loaded or initialized. Here are a few potential solutions:
1. Confirm that you have included the jQuery library before the QR Code library in your HTML file:
```html
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="path/to/jquery.qrcode.min.js"></script>
```
2. Make sure that the path to the `jquery.qrcode.min.js` file is correct and accessible.
3. Check if you have any conflicting libraries or scripts that might be causing issues with jQuery. Ensure that there are no errors or conflicts in the browser's console.
4. Verify that you are calling the `qrcode` function correctly. It should be called on a jQuery object. For example:
```javascript
$(document).ready(function() {
// Assuming you have an element with id "qrcode"
$('#qrcode').qrcode({
text: 'Your text here'
});
});
```
By following these steps, you should be able to resolve the "Uncaught TypeError: jQuery(...).qrcode is not a function" error.
