javascript - No database is running on event click -


this code working.

tx.executesql('insert routes (id_object) values (4)');  tx.executesql("select * routes", [], function (tx, result)  { alert(result.rows.item(0)['id_object']) }, function (tx, error) {alert('Неудача');} )};

but doesn't working. added click event.

 <button id = "click2">Добавить в БД</button>  function querysuccess(tx, results)  {  $('#click2').click(addobject);  function addobject(tt){  tt.executesql('insert routes (id_object) values (4)');  tt.executesql("select * routes", [],  function (tt, result) { alert(result.rows.item(0)['id_object']) }, function (tt, error) {alert('Неудача');} ) };

why that?

the transaction tx closed shortly after function querysuccess returns. click handler executed later, when doesn't have valid transaction.

you have create new transaction inside click handler.
