To use jsPDF with Knockout.js, you can create a custom binding handler in Knockout to generate a PDF document using jsPDF. Here is an example of how you can use jsPDF with Knockout.js:

1. Include the jsPDF library in your HTML file:

1

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/2.4.0/jspdf.umd.min.js"></script>

1. Create a custom Knockout binding handler to generate a PDF document:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

ko.bindingHandlers.generatePdf = {
    init: function (element, valueAccessor) {
        element.addEventListener('click', function () {
            var data = ko.unwrap(valueAccessor());

            var doc = new jsPDF();

            // Generate PDF content here
            doc.text('Hello, World!', 10, 10);

            doc.save('document.pdf');
        });
    }
};

1. Use the custom binding in your HTML template:

1

<button data-bind="generatePdf: data">Generate PDF</button>

1. In your Knockout view model, define the data that you want to include in the PDF document:

1
2
3
4
5

var viewModel = {
    data: ko.observable('Hello, World!')
};

ko.applyBindings(viewModel);

Now, when the user clicks the "Generate PDF" button, a PDF document will be generated with the content "Hello, World!" displayed on it. You can customize the PDF content by modifying the generatePdf binding handler function.
