javascript - Unable to fetch actual value from Web SQL database; it's returning undefined -

check code:

var db = opendatabase("despesas", "1.0", "despesas db", 2000000);         db.transaction(createtbl, errorcb, successcb);          function errorcb(err){             alert('error : ' + err.code);         }         function successcb(){             console.log('db created!');             db.transaction(querydb, errorcb);         }         function createtbl(tx){             tx.executesql('drop table if exists entries');             tx.executesql('create table if not exists entries (id integer primary key autoincrement, entry text not null)');          }          function callpopulate(){             db.transaction(                 function populatedb(tx){                             var userinput = document.getelementbyid('user').value;                     tx.executesql('insert entries (entry) values (?)', [userinput]);                     //tx.executesql('insert entries (entry) values ("'+ userinput + '")');                     //alert('input ok');                 }, errorcb, successcb);                   }          function querydb(tx){             tx.executesql('select * entries',[], querysuccess, errorcb);         }  function querysuccess(tx, results) {      document.getelementbyid('list').innerhtml = '';     var len = results.rows.length;           console.log("entries table: " + len + " rows found.");     (var i=0; i<len; i++){         item = results.rows.item(i);         console.log("row = " + + " id = " + results.rows.item(i).id + " data =  " + results.rows.item(i).data);         document.getelementbyid('list').innerhtml += '<li>' + item.data + '</li>';         console.log(item);     }    } 

i log item console, prints object stored. tried console.log(item.data), doesn't seem give me result expect. how supposed fix , return real value? using chrome.

it looks don't have column called "data" in table, or not selecting it.
