je viens de construire une galerie vidéoRetirez la navigation vidéo vacillante de la galerie vidéo
Voici le lien vers la galerie vidéo
http://www.braddockinfotech.com/demo/dvnonline/vod1/
Deux questions::
1) Lors de la navigation dans la galerie en utilisant les touches fléchées vers le haut et vers le bas, il y a une sorte de saut vidéo ou flicker.how pour enlever cela
2) Des espaces supplémentaires inégaux avant et après la première et la dernière vidéo en Galerie.
Voici le code html
<body onkeydown="HandleKeyDown(event);">
<table cellpadding="0px" cellspacing="0px" border="0px" class="sitewidth">

Vérifiez votre 'MoveToDirection ('Down');' fonction. Regarde comment ça marche. – user1477388
