设置jQuery Datepicker的最小/最大日期

Question

I am having trouble understanding how to set the min/max Date of the jquery Datepicker. When I check the docs , i see that the dateformat is expected in new Date(2009, 1 - 1, 26) . What does the 1-1 mean? When I chec w3c schools for js dateformats, I cannot find this one.

So I tried

$("#datepicker").datepicker({
    changeMonth: true,
    changeYear: true,
    dateFormat: 'yyyy-mm',
    minDate: new Date(2001-01),
    maxDate: '+15Y'
});

But that leaves me with completely random results... It starts 2006 and ends 2026.

Here is fiddle http://jsfiddle.net/ANF2y/58/

Answer 1

In JavaScript month is calculated from 0 to 11. So while creating a new Date use current month - 1 .

1 - 1 equates to 0 . So that is a valid month ( 0 - January ).

In your case set minDate as below.

$("#datepicker").datepicker({
  changeMonth: true,
  changeYear: true,
  minDate: new Date(2001, 0, 1),
  maxDate: '+15Y',
  dateFormat: 'yyyy-mm'
});

that is because the jquery date picker only shows 15 items at a time, there is no max date set so you can go as far in the future as you want. When it is set to 2001 you see 2006 in the dropdown as it is limited to 15 items. Select 2006 and then you'll see 2001 in the dropdown. Is your question can I show more items in the year dropdown list?

Answer 2

I'm not going to go into minDate or maxDate as that has been well covered. But in addition to that, what you are looking for is yearRange will set the number of visible items in the year dropdown of the jquery date picker.

The documentation states:

The range of years displayed in the year drop-down: either relative to today's year ("-nn:+nn"), relative to the currently selected year ("c-nn:c+nn"), absolute ("nnnn:nnnn"), or combinations of these formats ("nnnn:-nn"). Note that this option only affects what appears in the drop-down.
