            return false
        _.banners=[]
        $(_.items,_.me).each(function(i){
            var tmp
            _.banners[i]=(tmp=$('.'+_.bannerCl,this)).length?tmp:false
        })
        _.bannerShow(_.banner=_.banners[_.show].appendTo(_.me))//This is where the error es
    },

• 3 most likely _.banners[_.show] isn't a jQuery object. (in your code it can be either a jQuery object or false. when it is false, it will fail.) – Kevin B Commented Jul 11, 2013 at 21:45
• 1 @KevinB: Or undefined, if i never has whatever value is in _.show. – T.J. Crowder Commented Jul 11, 2013 at 21:48
• Is it = or == in that line? – f p Commented Jul 11, 2013 at 21:49
• 1 I would really, really not like to be the person who has to maintain that code. – T.J. Crowder Commented Jul 11, 2013 at 21:54

You're calling appendTo on _.banners[_.show]. From your code, it's entirely possible that _.banners[_.show] could be either false or undefined, not a jQuery object.

If in the each loop, if i is ever equal to whatever is in _.show, then _.banners[_.show] will be either a jQuery object (with an appendTo method), or false (which doesn't have one), depending on whether $('.'+_.bannerCl,this) found any elements.

If i is never equal to _.show, then _.banners[_.show] will be undefined, which doesn't have an appendTo method.

The only way to figure out exactly what's going on is old-fashioned debugging: Use the debugger built into your browser, sets breakpoints, single-step through the code, inspect variables at various points in the debugger's display of variables, etc., etc.
