我正在尝试制作一个魔术八球模拟，但它对我不起作用。Chrome 中的检查器元素没有显示任何错误，所以我很困惑为什么它不起作用。任何建议将不胜感激。

        function eightBall() {
            var answer = document.getElementById("answerBox").value;
            answer = answer.toLowerCase();

            if (answer.search(/[r]/) > 0 ) {

您没有对函数的返回值做任何事情。

您可能希望将其分配给<img>标签的src属性。

我看到的问题是，eightBall当单击按钮并选择正确的值时，您正在调用该函数，但您没有对它做任何事情，例如在myOutputdiv 中附加一个节点。

您还有两个身体标签。
