Editing jQuery.height() vs. jQuery.offset() This edit will create a new revision. Your details (optional) Name Email (won’t be displayed; might be used for Gravatar) URL Test case details Title * Published (uncheck if you want to fiddle around before making the page public) Description (in case you feel further explanation is needed)(Markdown syntax is allowed) In some cases, my algorithm could use with jQuery.height() or jQuery.offset().top to perform its function, so I would like to use whichever is faster. Are you a spammer?
