window.prompt 添加功能时停止工作

Question

var user = window.prompt("Welcome to the Vacation Planner. Please enter yourname");
document.getElementById("greeting").innerHTML += ", " + user;
var enterDays = document.getElementById("enterDays");
/*
function.calculateDays(){
    var dayMessage = document.getElementById("dayMessage");
    if(enterDays <4){
        dayMessage.innerHTML = "Short trips are always worth it!";
        }
    else if(enterDays<7){
        dayMessage.innerHTML = "Cool, you'll be there for a week"
        }
    else{
        dayMessage.innerHTML = "You'll have plenty of time to relax and have fun!"
        }
}*/
enterDays.onclick = calculateDays;

当我输入此代码时，window.prompt 可以正常工作。但是当我取消注释 function.calculateDays 时，window.prompt 停止工作。谁能解释为什么会发生以及如何解决？非常感谢！！！

Answer 1

function.calculateDays 不是有效的语法，会抛出一个语法错误，阻止未来的代码调用，要修复它，请将其替换为 function calculateDays.
