Here's a quick little tip that I discovered today about Javascript. I'm currently writing a small in-context help addon for jQuery and wanted to add the option to specify a class name to give a help bubble. I did this using a setting and checked for it like such: [javascript]if(settings.class != null) { bubble.addClass(settings.class); }[/javascript] This works great in Firefox, Opera, Chrome and even IE but throws an error in Safari. It took me a while to figure out what was going on but I finally figured out that 'class' is a reserved word in Safari Javascript. Changing the code to: [javascript]if(settings.classname != null) { bubble.addClass(settings.classname); }[/javascript] makes everything alright. So if you're getting a strange Parse error in Safari and nothing else, take a peek through your code and check you're not using the keyword class anywhere.
