我试图修改Google Code Javascript文件，以便获得链接访问的经验。我是javascript的新手，我真的不知道如何说出我想要做的事情。我认为它应该是这样的：
var exp = 0 //Current exp
var level = 1; // User Level
var tolvl = level * 100 //Exp to 'level up'
function expchange (exp) {
if (urlToCount <= 1) { //if they have visited the link once today
exp+=10; //Change variable 'exp' to "variable"+10
}
else {
exp+=5; // If more, change to "variable"+5
}
if (exp == tolvl ) { //If Variable 'exp' is equal to Variable 'tolvl'
level+=1; //Change variable 'level' to 'variable'+1
}
//I need some kind of function to write Variables to HTML
我可能做了一些可怕的错误，对不好的脚本感到抱歉。谢谢你的帮助

阅读并重新阅读您的代码后，我认为您需要这样的东西。 不确定tolvl计算，但其余的应该显示在何处以及如何更改
