For loop syntax question

1

Hi there everyone.
I have a silly question. I’ve seen examples of the for loop written for(i in this) but it never seems to work for me. The code below works if I use numbers but not the ‘this’ (whether I have the var in or not). Am I just writing it incorrectly? Thanks a bunch for looking!


for(var i in this){
	_root["m"+i].onRelease = function(){
		selectVid=this._name+".flv";
		video1.attachVideo(netVid); 
		netVid.setBufferTime(2); 
		netVid.play(selectVid); 
		_root.info_txt.htmlText = loadText[this._name];
		}
}



for(i=0;i<7;i++){
	_root["m"+i].onRelease = function(){
		selectVid=this._name+".flv";
		video1.attachVideo(netVid); 
		netVid.setBufferTime(2); 
		netVid.play(selectVid); 
		_root.info_txt.htmlText = loadText[this._name];
		}
}
