将字符串转换为数组中的日期对象

Question

I have a table which has a date string in the header. It is returned as part of an array but I need that date in the array to be a Date Object and not just a string.

My table is as follows

DEMO

// [[20th Jan, 33], [21st Jan, 44], [22nd Jan, 5],[23rd Jan, 17]]

I use the following JS to get this array

var arr = $.map($('#bookedTable th:not(:first)'), function(el,i) {
    return [[$(el).text(), $('#bookedTable td:eq('+i+')').text()]]
});

console.log(arr)

Question: How can I return the string dates as date objects in my array?

Answer 1

You need to ran something like this function on all your dates in array :)

function parseThisDate(date) {
  dateParts = date.split(" ");

  return new Date(dateParts[2], translateMonthToNum(dateParts[1]), dateParts[0])
}

function translateMonthToNum(monthName) {
  if (monthName == 'Jan,') return 0;
  //todo: add all months you need
}

Answer 2

You can always convert a string to date as

var myDate = new Date("2013/1/16");

You can clearly get the "2013/1/16" from the array provided the months are in numbers.
