ajax - jQuery and couchdb: is it possible to handle "created" and "already exist" in one handler? -

-

a typical pattern no use rest couchdb api "create if not exist". example, if want create database if it's not exist:

$.ajax({   type: 'put',   url: db + 'mydatabase', });

as programmer, both 201 created , 412 prerequisite failed success, since want database in place , it's fine me if it's created or here. jquery perspective, 201 success , 412 failure - need write lots of code make sure database in place:

$.ajax({   type: 'put',   url: db + 'mydatabase', }).fail( function( arg ) {   if( 412 == arg.statuscode ) {     // success.   } else {     //  failure.   } }).done( function( arg ) {   //  success. });

this makes code mess success in 2 places (even in 2 different callbacks!). possible somehow reduce error handling in less code, preferably processing success in 1 place?

alternatively can use statuscode object bind shared event handler 200 , 412.

$.ajax({     type: 'put',     url: db + 'mydatabase',     statuscode: {         200: myhandler,         412: myhandler     } });  function myhandler(data, statustext, jqxhr) {     // data }

for completeness here's other way described in comment.

$.ajax({     type: 'put',     url: db + 'mydatabase',     complete: function(jqxhr) {         if (jqxhr.status === 200 || jqxhr.status === 412) {             //         }         return;     } });
