　　一切都来源于上面这一组JSON数据，用JSON解析器可以看到这个JSON的结构，如下：

        }
    ]
}

　　（后台为了便于识别，写成了这样子，最初版本是精简版本的。）

　　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...
