数据是getJSON（）回调函数中的保留变量吗？

Question

Here is the descrition of getJSON in jquery :

$(selector).getJSON(url,data,success(data,status,xhr))

Here success(data,status,xhr) is a callback function when success. I often see the code below:

 $(select(.getJSON('my/url', function(data) {....});

Here variable data holds the data returned by the http server. My question is that instead of using name data here, can I use variable name like server_data as below?

 $(select(.getJSON('my/url', function(server_data) {....});

Answer 1

It's a function argument name. You can name it whatever you want, so long as it follows the valid javascript variable name format.

Edit: Also, easy enough to test without asking a question.
