Question

I currently use a annonymous function for the jquery ajax success-response.

success: function(data){
  code
},

When Trying to use a named function:

success: success(data),

It claims the the variable data is not set. I suppose i could do

success: function(data){
  success(data)
},

But this feels like it’s not how it’s suppose to be done. Why is it behaving this way and what should I do about it?

Answer 1

It’s because JQuery is expecting a reference to a function, not a function call.

JQuery needs to know what function has to call. With success(data) you are instead passing the result of the function call success(data) (which can be whatever, also void – no result) giving no clue at all for what to do.

The reference is something that points to an object, in this case a “function object”.
The function call can be thought instead as an action to perform that gives or gives not a result that is evaluated as an expression.

Just use:

success: success
