jQuery Error: ‘g is undefined’

09-05-20 17:59 Filed in: Fix | jQuery

Discovered the cause of this annoying (but seemingly impotent) error in a response by Karl Swedberg on Nabble.

The error was caused by my passing only one function to jQuery.hover(), eg:

 jQuery(".blog-entry-date").hover(function(){
                jQuery(this).animate({color: genHex()},100);
        });

Hover takes two functions. Instead ‘mouseenter’ should be used:

 jQuery(".blog-entry-date").bind('mouseenter',function(){
                jQuery(this).animate({color: genHex()},100);
        });

The error didn’t seem to have any effect on the execution of the code (at least in Firefox), but errors are errors, and the the cause should be hunted down. Always.
