noob question about function ()

I am not sure about this code. This structure is correct?

 success: function(data, data1, data3, .... ) {
                    switch (data.livre) {
                    case 'x':

                        break;
                    }

                    switch (data1.livre1) {
                    case 'y':

                        break;
                    }

       开发者_开发百科         }

thanks

For future reference here is a code quality tool : jshint

The above is indeed "correct" code as in it will parse correctly. But it can be improved though.

success: function(data) {
  if (data.livre === 'x') { 
    ... 
  }
  if (data.livre1 === 'y') { 
    ... 
  }

}

Be wary that you generally pass one result back. So you should get the server to pass an object or array of data back.

The real question is, do you have a problem? and what are you trying to achieve?

I'm not sure which part of the function you're asking about, but maybe you mean either:

function success( ... ) { .... }

Or,

success = function( ... ) { .... }

Using success: function doesn't make sense in isolation, but people are so used to reading that as a JS object property they might think its ok...

If that's inside of an object, sure. Looks right to me.

i.e.

var obj = {
     success: function(...
};
