Hi Bot help me. Here's my source code and showing the error Uncaught ReferenceError: jsPDF is not defined.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="You do not have permission to view the full content of this post. Log in or register now."></script>
<script src="You do not have permission to view the full content of this post. Log in or register now."></script>
<script src="You do not have permission to view the full content of this post. Log in or register now."></script>
</head>
<body>
<button id="generate-pdf">Generate PDF</button>

<script>
$(document).ready(function() {
var jsonData = [
// Your JSON data here
];
$('#example').DataTable({
data: jsonData,
columns: [
{ data: 'field1' },
{ data: 'field2' },
// Add more columns as needed
]
});


$('#generate-pdf').click(function() {
var doc = new jsPDF();
// Add image
var imgData = 'You do not have permission to view the full content of this post. Log in or register now.
doc.addImage(imgData, 'JPEG', 10, 10, 50, 50); // Adjust the positioning and size of the image
// Add header
var headerText = 'My PDF Header';
doc.setFontSize(18);
doc.text(headerText, 10, 80); // Adjust the positioning of the header text
// Get the data from DataTables
var tableData = $('#example').DataTable().data();
// Iterate over the data and add it to the PDF
$.each(tableData, function(index, data) {
doc.text(data.field1 + ', ' + data.field2, 10, 100 + (index * 10)); // Customize the positioning of the text
});
// Add footer
var footerText = 'Page ' + doc.internal.getCurrentPageInfo().pageNumber;
doc.setFontSize(10);
doc.text(footerText, 10, doc.internal.pageSize.height - 10); // Adjust the positioning of the footer text
// Save the PDF file
doc.save('data.pdf');
});
});
</script>
</body>
</html>
 
The error you are experiencing is due to the fact that the jsPDF object is not recognized or defined in your code. This can happen if the script file for jsPDF is not properly loaded or if there is a typo in the script URL.

To fix this issue, make sure that you have included the correct script file for jsPDF and that it is loaded before your code attempts to use it. Double-check the URL for the jsPDF script file and ensure that it is accessible.

In your code, you are already including the jsPDF script from the correct URL (You do not have permission to view the full content of this post. Log in or register now.). However, it seems that the URL formatting in your code is incorrect.

Replace the [URL] and [/URL] tags with regular HTML <script> tags to properly include the script files. Here's the corrected code:

HTML: 
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdn.datatables.net/1.10.21/js/jquery.dataTables.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/2.4.0/jspdf.umd.min.js"></script>
</head>
<body>
<button id="generate-pdf">Generate PDF</button>

<script>
$(document).ready(function() {
var jsonData = [
// Your JSON data here
];
$('#example').DataTable({
data: jsonData,
columns: [
{ data: 'field1' },
{ data: 'field2' },
// Add more columns as needed
]
});


$('#generate-pdf').click(function() {
var doc = new jsPDF();
// Add image
var imgData = 'https://images.pexels.com/photos/674010/pexels-photo-674010.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500';
doc.addImage(imgData, 'JPEG', 10, 10, 50, 50); // Adjust the positioning and size of the image
// Add header
var headerText = 'My PDF Header';
doc.setFontSize(18);
doc.text(headerText, 10, 80); // Adjust the positioning of the header text
// Get the data from DataTables
var tableData = $('#example').DataTable().data();
// Iterate over the data and add it to the PDF
$.each(tableData, function(index, data) {
doc.text(data.field1 + ', ' + data.field2, 10, 100 + (index * 10)); // Customize the positioning of the text
});
// Add footer
var footerText = 'Page ' + doc.internal.getCurrentPageInfo().pageNumber;
doc.setFontSize(10);
doc.text(footerText, 10, doc.internal.pageSize.height - 10); // Adjust the positioning of the footer text
// Save the PDF file
doc.save('data.pdf');
});
});
</script>
</body>
</html>

After making these changes, the jsPDF object should be defined and the error should no longer occur.

Its the same. Here's the error
pdf.php:30 Uncaught ReferenceError: jsPDF is not defined
at HTMLButtonElement.<anonymous> (pdf.php:30:11)
at HTMLButtonElement.dispatch (jquery.min.js:2:43090)

Apologies for the confusion. It appears that the issue lies with the order in which the JavaScript libraries are being loaded. As the error suggests, the variable jsPDF is not defined because the script for the jsPDF library is being loaded after the code that is trying to use it.

To resolve this issue, you need to make sure that the jsPDF library is loaded before the code that references it. In this case, you can move the script tag for the jsPDF library to the head section of your HTML file.

Here's the updated code with the jsPDF library script tag moved to the head section:

HTML: 
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/2.4.0/jspdf.umd.min.js"></script>
<script src="https://cdn.datatables.net/1.10.21/js/jquery.dataTables.min.js"></script>
</head>
<body>
<button id="generate-pdf">Generate PDF</button>

<script>
$(document).ready(function() {
  var jsonData = [
    // Your JSON data here
  ];

  $('#example').DataTable({
    data: jsonData,
    columns: [
      { data: 'field1' },
      { data: 'field2' },
      // Add more columns as needed
    ]
  });

  $('#generate-pdf').click(function() {
    var doc = new jsPDF();
    // Rest of your code...
  });
});
</script>
</body>
</html>

By moving the script tag for the jsPDF library to the head section, the library will be loaded before the rest of the code, ensuring that the jsPDF object is defined when it is used.

Try using this updated code, and the error should no longer occur.

Apologies for the confusion. The error suggests that the jsPDF library is still not being recognized. To troubleshoot this issue, try the following steps:

1. Make sure that the jsPDF library is being loaded properly. Check the network tab in your browser's developer tools to see if the library is being loaded successfully. If there is an error loading the library, try using a different URL or version of the library.

2. Double-check that the script tag for the jsPDF library is included in your HTML code and that the URL is correct.

3. If the jsPDF library is being loaded properly, try clearing your browser cache and reloading the page. Sometimes, cached versions of scripts can cause issues.

4. Confirm that your code is using the correct spelling and casing for the jsPDF object. The error message suggests that the object is not recognized, so make sure you are using the correct variable name.

If none of these steps resolve the issue, please provide more information about your environment, such as the browser you are using and any other relevant details.
