As processing.js doesn’t work on Internet Explorer (despite some simple examples on IE9) I give a message to IE users. The easiest way (but probably not the most elegant) consists in two modifications of the plugin:
1. Deactivate processing.js reference in header because of erros it produces on IE changing line 32 of processing-js.php:
if (isset($_SERVER['HTTP_USER_AGENT']) && (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') == false)) {
wp_enqueue_script('processing-js', plugin_dir_url(__FILE__) . 'js/processing-1.3.6.min.js');
}2. Show error message instead of Canvas adding code to line 8 of js/init.js and putting the rest of the code inside else statement:
if (jQuery.browser.msie) {
jQuery(document).ready(function($){
var script = jQuery("script[type*=processing]").get(0);
jQuery(script).after("<p>IE doesn't support canvas, please use Firefox or Chrome.</p>");
});
}
else {
//original javascript code of init.js
}To update Processing.js to the 1.0 release, download the 1.0 release from processingjs.org, rename the files and replace the old versions that came with the WordPress plugin (processing.js and processing.min.js), and make one change to the plugin’s init.js (line 27, replace “Processing” with “new Processing” as they changed the way the object is called).
