Answer 4

return hebj(hebj01)
也写
return hebj(‘hebj01’)

Answer 5

按照：knightzhuwei 的方法，解决了FF里的问题，谢谢各位的热心回复！如果  knightzhuwei ，可以带上点说明，为什么要这样做，FF才能生效呢

Answer 6

 hebj('hebj02'); 参数是字符串
case "hebj02": 判断字符串 这个比较保险hebj(hebj02); 参数是dom对象
case hebj02:  判断dom对象 ff可能不支持

Answer 7

谢谢 knightzhuwei  你的热心解说与帮助
