基本上,我试图让用户以mm / dd / yyyy的形式输入日期。它可以是任何日期,但必须选择它。我想要做的是计算自输入日期以来经过的年数,月数和天数。我已经达到了可以选择日期的程度,但除此之外,我很难过。这就是我所拥有的:

            <input type="date" id="dateSelected" />

          <label for "timeElapsed"> Time Elapsed: </label>

          </form>

如果我没记错的话,你的方式是将日期转换为毫秒,并从该数字转换,但我不太确定如何做到这一点用户输入的数据。有人可以帮忙吗?
