画面上の 2 つの div を同期しようとしていますが、何らかの理由で Firefox では機能しません。

私が見ることができるエラーは発生していません。単に機能しません。私はこれに困惑しています。他のすべてのブラウザで機能します。

誰かが助けてくれれば、私はとても感謝しています!

以下のスクリプトのほとんどを含めました...

ここ：

return function ()  
{ 
    if (oElement._scrollSyncDirection == "horizontal" || oElement._scrollSyncDirection == "both") 
        oElement.scrollLeft = event.srcElement.scrollLeft; 
    if (oElement._scrollSyncDirection == "vertical" || oElement._scrollSyncDirection == "both") 
        oElement.scrollTop = event.srcElement.scrollTop; 
};

使っていますがevent、Firefoxにはそのようなイベントはないと思います。検討：

return function (ev)  
{
    var target =  ev && ev.target ? ev.target : event.srcElement;

    if (oElement._scrollSyncDirection == "horizontal" || oElement._scrollSyncDirection == "both") 
        oElement.scrollLeft = target.scrollLeft; 
    if (oElement._scrollSyncDirection == "vertical" || oElement._scrollSyncDirection == "both") 
        oElement.scrollTop = target.scrollTop; 
};
