I'm trying to accomplish something similar to Wikipedia's History history page, dynamically disabling radio buttons in a series.

Ie... if #4 in group two is selected, then 1-4 of group one are disabled, etc.

I know how to disable them individually or as a group, but I'm not sure how to do it in a series of say 1-4:

Individually:

$("#version_history input[id^=versions_2_3]:radio").attr('disabled',true);

or group:

$("#version_history input[id^=versions_2]:radio").attr('disabled',true);

The inputs are named versions_1_X and versions_2_X, X being some number. 1..2..3.. etc.
