问题描述投票：0回答：1

JavaScript新手，我很难解决这个问题。非常感谢你

var attempts = 0;
var randomNumber;

while (randomNumber === 10) {
    randomNumber = (Math.random(10 - 1) + 1);
    attempts = attempts + 1;
}

document.write("It took " + attempts + " attempts");

javascript loops document

由于您正在调用document对象，因此代码应包含在HTML代码段中。该文档对象代表您的网页。如果要访问HTML页面中的任何元素，则始终从访问文档对象开始。

例如：

<!DOCTYPE html>
<html>
<body>

<script>
var attempts = 0;
var randomNumber;

while (randomNumber === 10) {
    randomNumber = (Math.random(10 - 1) + 1);
    attempts = attempts + 1;
}

document.write("It took " + attempts + " attempts");
</script>

</body>
</html>
