Canvas signature touch creates issue in phonegap

Question

I found a few posts related to \"phonegap canvas signature\" but they did not help. I have some drop down boxes, text boxes, and one signature field. I want to insert these

You really should be passing error callbacks to transaction() and executeSql() methods - it'll help debugging your database operations in development. You'll want to use something other than alert() for error handling in production.

db.transaction(function(tx) {
    // for parts table
    tx.executeSql(
        "insert into parts(nr,productid,description,toolsVerified) values(?,?,?,?)",
        [ nr, productId, desc, tool ],
        null, sqlError
    );

    // for cost table
    tx.executeSql(
        "insert into costs(nr,date,starttime,endtime,reason,cost) values (?,?,?,?,?,?)",
        [ nr, date, startTime, endTime, reason, cost ],
        null, sqlError
    );

    // for sign table
    tx.executeSql(
        'insert or replace into sign(orderNr,rapport,sign) values (?,?,?)'
        [nr, rapport, kundensUnderSkrift],
        null, sqlError
        );
}, xactError);

function sqlError(tx, err) {
    alert("Statement failed: " + err.message);
}

function xactError(err) {
    alert("Transaction failed: " + err.message);
}
