我正在看一个教程并遵循他的代码，但我自己命名了变量和函数，但是在我完成buyHelper函数之后，我的loadCode函数停止工作并且它一直说“{”是意外的。请帮忙。（除了css，我在一个文件中完成了所有代码，因为它不能在外部工作）

<!DOCTYPE html>
<script type="text/javascript">
    function update(){
            document.getElementById("amount").value = codeAmount;
                document.title = codeAmount + " Codes"
    }

    var codeAmount = 0;
    var codeHelper = 0;

    function timer(){
        codeAmount = codeAmount + codeHelper;
        update()
    }

    setInterval(timer, 1000);
</script>
<html>
    <head>
        <title>0 Codes</title>
        <link rel="stylesheet" type="text/css" href="clickerGame2.css">
    </head>
    <body>
        <h1>Click to get JavaScript code!</h1>

        <h2>Use your code to get upgrades!</h2>

        <a href=# onclick="addJS()"><img

        You Have:
        <input type="text" id="amount" disabled style>
        <script type="text/javascript">
            function addJS(){
                codeAmount = codeAmount + 1;
              update()
            }
        </script>
        lines of code.
        <br><br>
        <button><a href=# onclick="saveCode()" class="white">Save!</a>

        <button><a href=# onclick="loadCode()"class="white">Load!</a>
</button>
        <br><br>

        <p>Pay someone to help code!</p>

        <button><a href=# onclick="buyHelper()">Helper</a></button>

        <p id="helperCost"></p>

        <p id="helperAmount">You have 0 helpers.</p>

        <script type="text/javascript">
            function saveCode(){
                localStorage.setItem("codeAmount", codeAmount);
            }
            function loadCode(){
                codeAmount = localStorage.getItem("codeAmount");
                codeAmount = parseInt(codeAmount);
                update();
            }

            function buyHelper(){
                if (codeAmount >= ((codeHelper+1)*12){
                    codeAmount = codeAmount - ((codeHelper+!)*12);
                    codeHelper = codeHelper + 1;
                    update();
                }
            }
        </script>

    </body>

在buyHelper功能上你有2个错误。第一个您在if语句中缺少右括号，第二个在下一行您使用感叹号而不是 1

这是编辑后的功能：

function buyHelper(){
    if (codeAmount >= ((codeHelper+1)*12)){
        codeAmount = codeAmount - ((codeHelper+1)*12);
        codeHelper = codeHelper + 1;
        update();
    }
}
