功能不会运行，说它没有定义

Question

单击按钮时

/conf/server.xml

它在控制台中说＆＃34; Uncaught ReferenceError：游戏未定义＆＃34;。 我在脚本中将其定义为

System.out.println()

用

打电话给它

<button onclick="game();">Submit</button>

它不应该运行吗？

Answer 1

你的javascript中有一些错误。
javascript中没有 elseif 关键字。

其次，我们在支架订单方面存在一些问题。

这里有一个工作版本：

function game() {
    var number = document.getElementById("myNumber").value;
    var number = Number(number);
    stepnumber.push(number);
    var orignumber = number;
    if (number !== "NaN") {
        for (step = 0; step > 1; step + 0) {
            if (number % 2 === 0) {
                number = number / 2;
                stepnumbers.push(number);
                step += 1;
            }
            else if(number % 2 === 1) {
                number = number * 3;
                number += 1;
                stepnumbers.push(number);
                step += 1;
            }

            document.getElementById("output").innerHTML = "Your number, " + orignumber + " took " +
            step + " steps to reach 1, the numbers it went through (in order) were: "
            + stepnumbers.toString() + ". Thanks for using this random 'tool'!";
        }
    }
    else {
        document.getElementById("output").innerHTML = "You didn't type in a number, try again."
    };
}
