Question

我已经创建了一个游戏，用户在开始游戏之前输入他们的名字，当他们在游戏中掷两个骰子，并且获得两个匹配的骰子时，他们将有机会玩另一回合，但是当我单击“滚动”按钮，当再次进行下一轮比赛时，它将再次询问用户名。

当用户获得第二轮比赛机会时，如何让我一次提示输入姓名？

我考虑过要使用布尔值，但是我不确定如何实现它。

        var diceImage = ["images/1.jpg","images/2.jpg","images/3.jpg","images/4.jpg","images/5.jpg","images/6.jpg"];

        var practiceDate;
        var name;
        var sum = 0;
        document.getElementById("Dice1st").style.display = "none";
        document.getElementById("Dice2nd").style.display = "none";

        var rounding =1;
        var db = openDatabase('RollDice','1.0','Game DB', 2* 1024 * 1024);
        var msg;


        function roll() {
            start();
            var dice1 = document.getElementById("Dice1st");
            var dice2 = document.getElementById("Dice2nd");

            var math1 = Math.floor(Math.random() * 6);
            var math2 = Math.floor(Math.random() * 6);

            var button = document.getElementById("rollButton");

            document.getElementById("Dice1st").style.display = "";
            document.getElementById("Dice2nd").style.display = "";

            var firstValue = diceImage[math1];
            var secondValue = diceImage[math2];

            dice1.src = firstValue;
            dice2.src = secondValue;


            if(math1 == math2)
            {
                sum = sum + math1 +1 + math2 + 1;
                document.getElementById("rollButton").style.display ="";
                document.getElementById("rounding").innerHTML = "Number of Round(s): " + rounding; 
                document.getElementById("totalSum").innerHTML ="Sum of the Dice: " + sum;
                rounding++;
            }
            else
            {
                document.getElementById("rollButton").style.display ="none";
                sum = sum + math1 +1 + math2 + 1;
                document.getElementById("rounding").innerHTML = "Number of Round(s): " + rounding; 
                document.getElementById("totalSum").innerHTML ="Sum of the Dice: " + sum;
            }
            db.transaction(function (transaction) {
                transaction.executeSql('INSERT INTO game (name, noOfAttempts, timeOfAttempt, totalResult) VALUES (?, ?, ?, ?);',[name, rounding, practiceDate.getTime(), sum])
            })

        }

        function start() {
            name = prompt("Enter your name. ");
            if (name == null) return;

            practiceDate = new Date();
            document.getElementById("timeDiv").innerHTML = ""; 

            gameCount = 0;

        }

        function createLocalDB() {
            db.transaction(
                function (transaction) {
                    transaction.executeSql('CREATE TABLE IF NOT EXISTS game ( gID INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, name TEXT NOT NULL, noOfAttempts INTEGER NOT NULL, timeOfAttempt INTEGER NOT NULL, totalResult NUMERIC NOT NULL);',[],
                        function dataHandler (transaction, results) {},
                        function errorHandler (transaction, error) {
                            console.error("Error creating table: "+ error.code + ": " + error.message);
                        });
                });
        }

        function checkAnswer() {
            //save the results into database.
            db.transaction(function (transaction) {
                transaction.executeSql('INSERT INTO game (name, noOfAttempts, timeOfAttempt, totalResult) VALUES (?, ?, ?, ?);',[practiceDate.getTime(), name, noOfAttempts, timeOfAttempt, totalResult])
            })
        }

        function processResult(transaction, results) {
            displayResult(results);
        }

当用户单击“滚动”按钮时，它将开始游戏，如果他们获得匹配的骰子，它将允许用户进行另一轮游戏。我在WebSQL中存储数据，例如名称，回合数，尝试时间和总结果，但是当用户获得第二次机会时，Web-SQL将显示重复数据。

每次用户单击玩游戏的按钮时，我都使用Web-SQL来存储名称，但是它要求输入两次该名称
