jQuery推迟（没有承诺）

以下工作，但我想知道我是否正确使用延迟对象：

var dbo = openDatabase('dbName','1.0','Description goes here', 1048576); console.log(jQuery.fn.jquery); // 1.7.1 var myDeferred = new jQuery.Deferred(); dbo.transaction(function(myTrans) { myTrans.executeSql( 'CREATE table IF NOT EXISTS myTable(myTableID INTEGER PRIMARY KEY ASC, myTableName Varchar(20))', [], function(myTransaction,myResult) { myDeferred.resolve(myTransaction,myResult) }, function(myTransaction,myResult) { myDeferred.reject(myTransaction,myResult) } ); }); myDeferred.done(function(A,B) { console.log('.done'); console.log(A); console.log(B); }); myDeferred.fail(function(A,B) { console.log('.fail'); console.log(A); console.log(B); });
