从文本中提取日期

Question

我使用此代码无需时间从文本中提取日期。是否有任何方法可以在没有时间的情况下提取日期，反之亦然？

$(document).on("change", "#select_date", function() {
  const at = $('#select_date :selected').text()
  //2016-03-26 15:22:02 
  const attend_date = at.substring(0,10)
});

Answer 1

您可以按空格split()日期并选择第一部分：

$(document).on("change", "#select_date", function() {
  const at = $('#select_date :selected').text()
  const attend_date = at.split(' ')[0]
})

Answer 2

$(document).on("change", "#select_date", function() {
  const at = $('#select_date :selected').text()

  //extract date
  const attend_date = at.split(' ')[0]
  //extract time
  const attend_time = at.split(' ')[1]
})
