批量设置flash文档中TextField 使用设备字体

这是一段jsfl代码：

var selecteArr = new Array();
function doWork(lays)
{
		for (var k in lays) {
            //遍历图层
			var layer = lays[k];
			var oldLoked = layer.locked;
			layer.locked = false;//解锁图层
			layer.visible = true;
			var frames = layer.frames;
                        for (var n in frames) {
                                //遍历所有帧
				var elements = frames[n].elements;
                                for (var m in elements) {
                                        //遍历所有帧里的可视元素
                                        if (elements[m] == "[object Text]") {
                                                //只有文本才执行下面的操作
						if(selecteArr[selecteArr.length - 1] != elements[m]){
							selecteArr.push(elements[m]);
							fl.trace(elements[m] +" "+ elements[m].name);
						}
                                        }
                                }
                        }
                }
		fl.getDocumentDOM().selection = selecteArr;
		fl.getDocumentDOM().setElementProperty('fontRenderingMode','device');
		fl.getDocumentDOM().selectNone();
}
//处理库中元件
var lib = fl.getDocumentDOM().library.items;
var i = 0;
for (i in lib) {
        //遍历所有库元件
        if (lib[i].itemType == "graphic" || lib[i].itemType == "movie clip") {
		fl.trace(lib[i].name);
		fl.getDocumentDOM().library.editItem(lib[i].name);
		selecteArr = new Array()
                //判断，只有图形元件和影片元件里含有文本
		var lays = lib[i].timeline.layers;
                doWork(lays);
        }
}
//处理舞台对象
i = 0;
var curTimelines = fl.getDocumentDOM().timelines;
while(i < fl.getDocumentDOM().timelines.length){
	selecteArr = new Array()
	fl.trace(curTimelines[i].name);
	doWork(curTimelines[i].layers);
	++i;
}
fl.getDocumentDOM().save();//保存文件
