Quick Fix: Apply a CSS class with page-break-inside: avoid; to the container element and use JavaScript to calculate the content height and insert page breaks using addPage() when necessary.
The Problem:
When converting HTML to PDF using the jsPDF library, it is challenging to control page breaks dynamically. In scenarios with substantial HTML content and custom styles, page breaks may occur at inappropriate locations, causing content to be split across multiple pages unintentionally. The goal is to find a solution that allows for proper page breaks without manually adding HTML elements like <br> to force breaks.
The Solutions:
Solution 1: Dynamic Page Break Handling
To address the page break issue when converting HTML to PDF using jsPDF, the following steps can be taken:
CSS Class for Page Breaks: Define and apply a CSS class named "page-break" to the form content container element. This class should have the property "page-break-inside: avoid;" to prevent the form content from being split across pages.
JavaScript for Page Height Calculation: Use JavaScript to dynamically calculate the height of the content. When the content size exceeds the maximum height for a page, a page break is inserted by calling the "addPage()" method of jsPDF.
Iterative PDF Generation: Iterate through each page and render the content using jsPDF’s "fromHTML()" method. This ensures that the form content remains on the same page as the table headers.
By combining the CSS class and JavaScript logic, page breaks can be dynamically inserted to keep the table header and body together on the same page.
