于是用了$.each()来遍历之，写了好几层...
var obj = group_authority_list;$.each(obj, function(k, v){ if(k == "group_id_"+urlId){ $.each(v, function(kk, vv){ $.each(vv, function(kkk, vvv){ for(var i in vvv){ if(vvv[i] == urlId)continue; _inputAuthList.each(function() { if( $(this).val() == i ){ $(this).parent('span').addClass('checked'); } }); } }); }); }}); 目标是把遍历到的对应权限，在输入框中选中，于是各位可以感受一下...
