var fetchResults = tx.executeSql("SELECT * FROM sessions WHERE sessions.dayid=1 ORDER BY sessions.starttime ASC", [],
        function(tx, data){
            processorFunc(data);
            var contxt = "";
            for (var numb = 0; numb < data.rows.length; numb++) {
                contxt += data.rows[numb].title + "=" + data.rows[numb].startTime + "=" + 
                        data.rows[numb].endtime + "=" + data.rows[numb].type + "\n";
            }
            console.log(contxt);
            contxt = "";
            for (var numb in data.rows) {
                contxt += data.rows[numb].title + "=" + data.rows[numb].startTime + "=" + 
                        data.rows[numb].endtime + "=" + data.rows[numb].type + "\n";
            }
            console.log(contxt);
        });

In console, I see that for-in loop returns two more lines and all elements are undefined. I use Web Sql API here. enter image description here

Does anybody know why this will happen?

  • The part of the linked answer that applies to your case here is likely “In addition, if any monkey patches or shims are put into place on the array object, they can show up here.”, and you can confirm that by logging numb each time around the loop. Commented Mar 3, 2017 at 19:42
  • got it, thanks, though don't fully understand :P Commented Mar 3, 2017 at 19:57
