javascript - 在圣诞节调用函数

Question

我在尝试只在圣诞节那天下“雪”时遇到了一些麻烦。我想出了如何捕获这一天，但我不确定如何让它正确调用 SnowStorm()。

var christmas = {
  month: 11,
  date: 25
}

function isItChristmas() {
  var now = new Date();
  var isChristmas = (now.getMonth() == christmas.month && now.getDate() == christmas.date);

if (isChristmas)
    return ;
  else
    return ;
}

var snowStorm = null;

function SnowStorm() {
    (snowstorm code)

}

snowStorm = new SnowStorm();

Answer 1

如果你打算创建一个函数(而不是一个类)，这里是版本:

var christmas = {
  month: 12,
  date: 25
}

function isItChristmas() {
  var now = new Date();
  return (now.getMonth() == christmas.month && now.getDate() == christmas.date);
}

if (isItChristmas()){
    SnowStorm();
  }else{
    //not a christmas
}
    
function SnowStorm() {
    (snowstorm code)
}

如果您打算上课，请看这里:

var christmas = {
  month: 12,
  date: 25
}

function isItChristmas() {
  var now = new Date();
  return (now.getMonth() == christmas.month && now.getDate() == christmas.date);
}

var storm = new SnowStorm();

if (isItChristmas()){
    storm.Snow();
  }else{
    //not a christmas
}
    
function SnowStorm() {
    this.Snow = function(){
        (snowstorm code)
    }
}
