Question

我的约会日期格式为2011-04-01。当我运行以下代码时，会产生以下结果。

var dateParts = '2011-04-01'.split('-');
dateParts[0] = parseInt(dateParts[0]);
dateParts[1] = parseInt(dateParts[1]);
dateParts[2] = parseInt(dateParts[2]);
console.log(dateParts);
for (i = 0; i <= 13; i++) {
  var thisDate = new Date(dateParts[0], dateParts[1], dateParts[2] + i);
  console.log(thisDate);
}

结果：

[2011, 4, 1]
Date {Sun May 01 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Mon May 02 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Tue May 03 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Wed May 04 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Thu May 05 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Fri May 06 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Sat May 07 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Sun May 08 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Mon May 09 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Tue May 10 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Wed May 11 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Thu May 12 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Fri May 13 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}
Date {Sat May 14 2011 00:00:00 GMT-0400 (Eastern Daylight Time)}

我分割的日期和我给出Date对象的数字是4月份，为什么它会在5月生成日期？我对JS有点新鲜，所以可能会有一些我不知道的东西。任何有关改进的帮助或建议都将受到赞赏。

某些JavaScript日期部分数组基于零：例如天数：0 =＆gt;星期日，月份：0 =＆gt;一月
