switch 循环

相对于if判断语句执行效率更高
function actStatus(Status){
	var statusData;
	switch (Status){
		case "0":
		  statusData = "结束";
		break;//停止、结束
		case "1":
		  statusData = "报名中";
		break;
		case "2":
		  statusData = "进行中";
		break;
		case "3":
		  statusData = "已结束";
		break;
		case "4":
		  statusData = "已取消";
		break;
	}
	return statusData;
}
