哈咯。。您们好。。。。。。希望javascript高手们。帮帮忙啊！
i got a list of radiobutton, with differnt name.
when i click on the radio button, it willpass the 'ID' into the JS function, how can i get the CHEKED radio ID and put in the hidden field first? i wan to put the all checked radio ID separated by a specified delimiter, such as in this format--> 1.2.3.4.5.6 with the delimiter '.'
谢谢您们。。。

可以看看我的coding 吗？我要当选那个radio button时，会call chkphoto(photoid) function,然后pass into text box(hidden field)，谢谢。

你没有hidCounter这个Object，也没total_file这个Object。
