as2 删除层级影片问题

关键要将main的引用赋值，防止被误删，导致加载swf空白

/**
 * 删除所有对象
 * @paramstandByRemoveMc      影片对象
 * @paramremoveSelf           是否删除自身
 * @param   otherMc              main的引用
 */
public static function removeAllMcs(standByRemoveMc:MovieClip,removeSelf:Boolean,otherMc:Object){
var m:MovieClip;
for (var i in standByRemoveMc){
m = standByRemoveMc[i];
//trace(m +"   " + standByRemoveMc + "   " + standByRemoveMc._parent)
//trace(m != standByRemoveMc)
//trace(m != standByRemoveMc._parent)
if (m != standByRemoveMc && m != standByRemoveMc._parent&&m!=otherMc){
m.getDepth() < 0 ? m.swapDepths(m._parent.getNextHighestDepth()) : 0;
m.removeMovieClip();
m = null;
}
}if(removeSelf){
standByRemoveMc.getDepth() < 0 ? standByRemoveMc.swapDepths(standByRemoveMc._parent.getNextHighestDepth()) : 0;
standByRemoveMc.removeMovieClip();
standByRemoveMc = null;
