The events onbeforeprint() and onafterprint() are supported by Internet Explorer, but they lack cross-browser compatibility. This article explores an alternative approach that utilizes more modern and widely supported technologies.
To implement a browser-agnostic solution for intercepting print events, consider using a combination of the window.matchMedia API and window.onbeforeprint or window.onafterprint. window.matchMedia allows you to detect when specific CSS media queries, such as print, are satisfied.
Here's a sample code snippet that illustrates this approach:
<code class="javascript">if ('matchMedia' in window) { // Chrome, Firefox, and IE 10+ support mediaMatch listeners window.matchMedia('print').addListener(function(media) { if (media.matches) { beforePrint(); } else { // Fires immediately, so wait for the first mouse movement $(document).one('mouseover', afterPrint); } }); } else { // IE and Firefox fire before/after events $(window).on('beforeprint', beforePrint); $(window).on('afterprint', afterPrint); }</code>
By combining matchMedia and onbeforeprint/onafterprint, this solution provides a cross-browser way to detect and respond to print events. Note that multiple calls to beforePrint() and afterPrint() may occur in some browsers, depending on the print behavior.
