;Erreur manquante après l'emballage du prototype

Question

Après avoir utilisé Packer (http://dean.edwards.name/packer/), je finis par lancer une disparue;après (la longue chaîne de packer).Je n'ai aucune idée du quoi et du pourquoi.solution possible et explication s'il vous plaît ?

Answer 1

Packer confie tout sur une ligne si je ne me trompe pas, de sorte que tout point-virgule manquant qui aurait été analysé à l'origine, ok se transforment en erreurs difficiles.

Il y a quelques points-virgules manquants dans votre JS par exemple

return function(angle)
{
    this._vimage.style.rotation=angle;
    var radians=angle*Math.PI/180;
    this._vimage.style.top=  (this._img._heightMax - this._img.height)/2- (this._vimage.offsetHeight-this._img.height)/2 +"px";
    this._vimage.style.left= (this._img._widthMax - this._img.width)/2- (this._vimage.offsetWidth-this._img.width)/2 +"px";
}

manque un point-virgule.Il y a plus.

Voici un joli site qui vous dira ce qui ne va pas avec votre javascript : http://jslint.com/

Alors collez là votre code, cliquez sur le JSLint et observez les erreurs et les avertissements que vous recevez.Une fois que vous les aurez corrigés, vous pouvez être sûr qu'une fois compressé, votre javascript fonctionnera.
