air 调用jsfl 执行对应函数，并传参

jsflPath = "WindowSWF/dt_tool_jsfl/" + event.item.fileName+".jsfl";
				var element_arr = event.item.element.split(",");
				var element_str:String = "";
				var elementLen_num:Number = element_arr.length;
				if (elementLen_num == 1){
					element_str = event.item.element;
				}else{
					for (var i:int = 0; i < element_arr.length; i++){
						if (i == 0){
							element_str +=  element_arr[i] + "\',";
						}else if (i == element_arr.length - 1){
							element_str += "\'" + element_arr[i];
						}else{
							element_str += "\'" + element_arr[i] + "\',";
						}
					}
				}

				doActionByElem(command,jsflPath,element_str);
//执行命令调用jsfl带参数
		private function doActionByElem(command:String,path:String="",element:String=""):void
		{   

			MMExecute("fl.runScript( fl.configURI + '" + path + "','" + command + "','" + element + "');");
			trace("fl.runScript( fl.configURI + '" + path + "','" + command + "','" + element + "');");
		}
