这里的问题是，当代码运行时，它会运行函数newJob，然后它告诉我intelligence是undefined，我将它定义为colleageChoice == 5 ，或1和5之间的任何内容，但似乎没有定义它。如果有人能够诊断为什么它没有被定义，那将会有很大的帮助。
提前致谢！
如果您需要更多信息，请告诉我！

您var intelligence仅在方法colleage()的范围内。如果您想在其他方法中引用var，则需要在外部创建intelligence：
var intelligence;
function colleage() {
...
if(colleage == true) {
alert("Welcome to colleage " +colleageChoice +"!. For coming here, you have earned 5,000 intelligence. This can be used to earn better jobs later on.");
intelligence = 5000;
}
if(colleage == false) {
alert("We're sorry you choose not to go to colleage, but for your troubles a team of people taught you some basic job skills. You earned 500 intelligence from them. Intelligence can be used to earn better jobs later on.");
intelligence = 500;
}
}
您还可以返回变量：
function colleage() {
...
if(colleage == true) {
alert("Welcome to colleage " +colleageChoice +"!. For coming here, you have earned 5,000 intelligence. This can be used to earn better jobs later on.");
return 5000;
}
if(colleage == false) {
alert("We're sorry you choose not to go to colleage, but for your troubles a team of people taught you some basic job skills. You earned 500 intelligence from them. Intelligence can be used to earn better jobs later on.");
return 500;
}
//it shouldn't reach here but make sure to handle this case if it does
}
var intelligence = colleage();

您正在尝试使用其范围之外的变量。变量intelligence仅存在于函数colleage()中。如果您需要一个由多个函数使用的变量，您可以在全局空间中声明它，就像您声明了transactionSubVar一样。
