In the following code, I am attempting to act upon the li element being hovered over. HTML: JavaScript: $(document).ready(function () { $('#featured ul li').hover(function(){ //do stuff, or not }); }); But this line of code is causing the following error in FF and I'm clueless as to what is causing it. g.guid is undefined This occurs even if the line of JS has nothing occurring inside the function. Any insight would be welcome :) JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

What version of jQuery are you using? That sounds like an old version. Also prior to v1.4, .hover() takes two functions.
