问题 I would like have three mouse actions over a control: left, right and BOTH. I've got the left and right and am currently using the middle button for the third, but am curious how I could use the left and right buttons being pressed together, for those situations where the user has a mouse without a middle button.

问题 I have the following snippet of code (I'm using jQuery 1.4.2): $.post('/Ads/GetAdStatsRow/', { 'ad_id': id }, function(result) { $('#edit_ads_form tbody').prepend(result); $(result).find('td.select-ad input').attr('checked','checked').click(); }); Assume that the post works correctly and returns a correct pre-built <tr> with some <td> s.
