javascript - 未捕获的语法错误 : x is not defined

Question

这里的问题是，当代码运行时，它开始运行函数newJob，然后它告诉我intelligence is undefined，我将其定义为 colleageChoice == 5，或 1 和 5 之间的任何内容，但似乎没有定义它。如果任何人都可以诊断为什么它没有被定义，那将会有很大帮助。

提前致谢!

如果您需要更多信息，请告诉我!

您的var Intelligence仅位于方法colleage()的范围内。如果你想在其他方法中引用var，那么你需要在外部创建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();
