把问题用粗体放在哪里，由于某种原因，按钮在按下时什么都不做......

所以，是的，在 html 中测试它，我认识的人谁知道一些 html/javascript 似乎认为表单被破坏或类似的东西......

编辑：让它工作，如果有人读到这个，如何在 javascript 中舍入？编辑：向上，而不是向下

您需要maxen在全局范围内声明变量

var level = "0"; var brawlpoints = "0"; var brawlenergy = "0"; 
var pointsmake = "0";
//declare the maxen variable here
var maxen = "0";

function setlv()
{
//left of your code

maxen被声明为函数中的局部变量，setlv并且您试图在另一个函数中访问它。让它全球化
