Question

我做错了什么？ ExecuteSql不会抛出任何错误，但实际上没有新条目插入表中。

// connection

var shortName = 'resultsDB';
        var version = '1.0';
        var displayName = 'QuizResultsDB';
        var maxSize = 655360;
        localDB = window.openDatabase(shortName, version, displayName, maxSize);

// tables are created succesfully

createTables: function(){

        localDB.transaction(function(tx){

            // add not null to email
            var query = 'CREATE TABLE IF NOT EXISTS results(User_ID INTEGER PRIMARY KEY, Name VARCHAR(255) NOT NULL, CompanyName VARCHAR(255) NOT NULL, EmailAddr VARCHAR(255) NOT NULL, TimeCount INTEGER NOT NULL, ErrorsCount INTEGER NOT NULL)';
            tx.executeSql(query, [], function(tx, data){
                    }, function(tx, error){
                    //alert('Database table creation error' + error.message + '(' + error.code + ')');
                });
        });
    }, // -createTables

//尝试插入行

localDB.transaction(

                function(tx){

                    var query = 'INSERT INTO results(Name, CompanyName, EmailAddr, TimeCount, ErrorsCount) VALUES(?, ?, ?, ?, ?)';

                        tx.executeSql(query, [$.cookie('name'), $.cookie('companyName'), $.cookie('email'), parseInt($.cookie('timeNeeded')), parseInt($.cookie('errorsCount'))], function(tx, data){
                    // no error thrown

                        }, function(tx, error){
                        alert("Error saving results to local database " + error.message);
                    });

你还记得做过交易承诺吗？

为什么新条目没有插入数据库？
