function readfromdatabase(){   try {   alert("in readfromdb before");   var db = window.opendatabase("surveryappdb", "1.0", "surveydb", 1000000);   db.transaction(function (tx) {   tx.executesql("select * projects;", [], successfetch, errorfetch);   alert("after execution");   });   }   catch(e) {   alert("unknown error "+e+".");   }   }   settimeout(function () { readfromdatabase() }, 500);    function successfetch(tx, resultset){   alert("before display rows in success");   displayrows(resultset.rows);   }    function errorfetch(tx, error){   alert("error processing sql: "+json.stringify(error));   }
