我看了几遍，我不知道我做错了什么...... 对不起发布整个事情，但我甚至无法真正缩小错误的位置，我检查了类似的代码，我的工作正常，我找不到其他的名称，我一致的差异。 ..按钮是不起作用的。谢谢你的帮助。

Javascript输出控制台

Uncaught ReferenceError: calculate is not defined test.html:64

你缺少很多东西：比如

// lv is not defined anywhere before using here
var maxen = 95+(lv*5);
var exptolv = 110+(lv*15);

在这里缺少concat运算符

alert("points per brawl = " + brawlpoints + "; energy per brawl = " brawlenergy);

应该是

alert("points per brawl = " + brawlpoints + "; energy per brawl = " + brawlenergy);

此处缺少收盘报价

document.write("To achieve your goal it will take you " + math1 + " brawls, this will take you " + math2 + " energy, or " + math4 + " levels, assuming a 75% refill levels you.);

应该是

document.write("To achieve your goal it will take you " + math1 + " brawls, this will take you " + math2 + " energy, or " + math4 + " levels, assuming a 75% refill levels you.");

还有更多 .. 养成使用javascript控制台的习惯，这样你才能知道代码出错的地方..

您输入的文档存在一个拼写错误，而不是文档。可能是它导致错误。

我在下面的代码中做错了什么？
