jquery ui datepicker back button jumps to 1899

问题:

I must be missing some setting or something, but when I use the back button the datepicker jumps to 1899 from the current year.

Has anyone else seen this and fixed it?

(You can see the different combos I've commented out.)

    $('.dialog-search,#from')
   .datepicker({
    defaultDate: 'c-1m',
    dateFormat: 'yymmdd',
    //changeMonth: true,
    changeYear: true,
    showAnim: 'fadeIn',
    duration: 200,
    //gotoCurrent: true, 
    showOtherMonths: true,
    selectOtherMonths: true,
    currentText: 'Now',
    shortYearCutoff: '+20',
    //showWeek: true,
    //firstDay: 1,
    numberOfMonths: 1,
    showButtonPanel: true,
    yearRange: 'c-200:c',
    onSelect: function(selectedDate,inst) {
     $('.dialog-search,#from').val(selectedDate);
    }
   });

I had this issue when I had multiple text inputs with the same ID, which is easy to do with MVC frameworks when you have multiple editors on page for same model class. I resolved it by explicitly specifying Id and leaving Name as is, so that model resolving works on postback.

This was caused by having multiple input fields with the same id, in my current project.

I was generating multiple forms at the front end, with the same creation method in my framework.

To avoid having to write explicit changes at the form creation level, I did the following:

//An initialisation method for datepickers
var init_datepickers = function() {
  /* Datepickers */
  $('.datepicker').datepicker({
    dateFormat: "dd/mm/yy" //(I'm in NZ)
  });
}
//Define counter ("datepicker index" aka dpi)
var dpi = 0;
//Loop datepickers
$.each($('input.datepicker'), function() {
  if(dpi > 0)
    $(this).attr("id", $(this).attr("id") + "_" + dpi); //Append the current count to the ID
  dpi++;
  //Check for last datepicker, and call init
  if(dpi == $('input.datepicker').length)
    init_datepickers();
});

This ads a number to all datepickers, other than the first one that appears on the page.

Note: This example doesn't really call for the use of ID's as selectors for scripts or styling. This will change the ID's of the inputs, and therefor, will break any styling / selection that you may have.

I experienced this issue when calling

$(...).datepicker('destroy')

before re-initializing the datepicker.

回答4:

It happens when if you have a default instance, because in jQuery plugin its configured that default date is 1899.

We have to just find out why this when this default date code fires

I have created a demo with your code in jsfiddle and I can't reproduce your problem. Can you check it at http://jsfiddle.net/w78xX/.

回答6:

I have same issue. I'm populating datepicker fields with ajax and showing them on PrettyPhoto as popup.

Here is my code.

$( "body" ).on( "focus", ".tarih", function() {
    //$('.tarih').datepicker('destroy');
    var i = 0;
    $('.tarih').each(function () {
        //$(this).attr("id",'date' + i).datepicker('destroy');
        $(this).attr("id",'date' + i).datepicker({
            dateFormat: "yy-mm-dd",
            firstDay: 1,
            minDate: new Date(2000, 1 - 1, 1)
        });
        i++;
    });
});

回答7:

Try using: format: 'mm/dd/yyyy hh:ii:ss P' The trick is to keeping your date format the same as what the back-end returns.

回答8:

I had the same issue and adding the useCurrent: false resolves it.

.datepicker({
        useCurrent: false 

    });
