javascript - Async function not working -

I am using rades using nodes (nod_redis module) and am trying to wrap my recovery code for debugging and drought.

Trouble understanding why the following function 'is not working'

I am more than basic async with Javascript, so I do not think this is anything to do except JS.

It works fine, but it is very redundant when there is a cover:

  // asyncLoad (className, id, callback) {redisClient.hget (className) , Id, callback); } // execution asyncLoad ('person', 1234, function (error, res) {if (err) {console.log (err);} else {var obj = JSON.parse (res); console.log (obj) ;}});  

I thought that if I can do this it would be useful for debugging and repetition, but I am definitely doing something wrong ...

  // AsyncLoad2 (className, id, callback) {redisClient.hget (className, id, function (error, res, callback) {console.log (callback); if (error) {console.log (err) );} Else {var obj = JSON.parse (res); callback (obj);}}); } // execution asyncLoad2 ('person', 1234, function (obj) {// easy way to get a parsed object back with previously handled error}  

thanks advance Thank you! I know that it's really dealing with lame error, I'm not expecting it to be used all the time, only for select things, and especially during debugging.
