Question

I have a bookid and i need to pass it on sqlite transaction in cordova
like

var bookName  = db.transaction(function(tx){
                    return tx.executeSql('SELECT * FROM Iqra_Book WHERE book_id=?',[1],function(tx,res){
                        var leng = res.rows.length;
                        console.log("Length: " + leng);
                        return bkName = res.rows.item(0).book_name;
                    }
                , function(e) {
                    return console.log("ERROR: " + e.message);
                });
            });

But I am getting this booName as undefined.
Can anyone help me out ?

Answer 1

you need to pass a variable to the book id. leave away the “return”, you cant just return a value since the web database works asynchrounously

tx.executeSql('SELECT * FROM Iqra_Book WHERE book_id ="'+id+'"',[1],function(tx,res){

also, change the line

return bkName = res.rows[0].book_name;

to

return bkName = results.rows.item[0].book_name;

and check if it works
