我能'；t read db.transaction（WEBsql、javascript、jquery）

在我的

$（文档）.ready（函数（）{…}

我有我的纽扣

$（'#saveDate'）。单击（函数（）{
insertDateOfProcedure（）；
showRecords（）；
});

它有两个功能，第一个是

   function insertRecordPaziente()
    {   
    var nome=$('#id').val();
    var bday=$('#bday').val();
    var clinicalNotes=$('#clinicalNotes').val();
    var fkPaziente=null;
    db.transaction(function (tx) {
    tx.executeSql('INSERT INTO paziente (nomePaziente, bDay, sex, clinicalNotes ) VALUES (?, ?, ?, ?)' , [nome, bday, radioButtonSex(), clinicalNotes] );        
    });         
}   

二是

function saveFK(){
db.transaction(function (tx) {
alert("??");
tx.executeSql("select seq from sqlite_sequence where name='paziente';", [], function (tx, result)
            { 
            alert("12334");
            dataset = result.rows; 
            if(dataset.length > 0)
            {
            for (var i = 0, item = null; i < dataset.length; i++)
            { 
                alert("ciao Mondo b");
                item = dataset.item(i);                                                     
                console.log(item['seq']);
                 fkPaziente=item['seq'];
                alert("fkPaziente:   "+fkPaziente); 
                return fkPaziente;            
            }            
            } else {alert("problemi con transiction");}              
        }); 
});
}

你能帮我吗

var db=openDatabase("hospital2", "1.0", "hospitalDatabase", 200000);
