关于FCKeditor_OnComplete的问题

Question

function FCKeditor_OnComplete(editorInstance){             
         editorInstance.Events.AttachEvent("OnFocus",FCKeditor_OnFocus);          
}   
        
function FCKeditor_OnFocus(editorInstance){
    parent.insert("frame");
}

 使用FCK后，想在FCK获得光标的时候，做一些事情，于是用到了FCKeditor_OnComplete这个方法，但是为什么下面的这个在FF下不能运行呢

editorInstance.Events.AttachEvent("OnFocus",FCKeditor_OnFocus);

Answer 1

ff下注册事件用addEventListener

var o=editorInstance.EditorDocument;
if(o.attachEvent){
o.attachEvent("onfocus",FCKeditor_OnFocus);
}else{
o.addEventListener("focus",FCKeditor_OnFocus,false);
}
