JQuery Datepicker，无法手动触发onSelect事件！ [英] JQuery Datepicker, can't trigger onSelect event manually!

问题描述

我正在使用jquery的datepicker，每当从内联datepicker对象中挑选一个日期时，会从ajax调用中填充项目列表。该脚本工作完美，除了我无法触发onSelect事件填充我的初始项目列表。

I am using jquery's datepicker where a list of items is populated from an ajax call whenever a date is picked from an inline datepicker object. The script works perfect except that I can't trigger an onSelect event to populate my initial list of items.

我可以解决这个问题，只是最初使用php，但我真的很想避免这种情况。

I could get around this problem by just populating the list initially using php but I would really like to avoid this.

    $(document).ready(function(){

        //create date pickers
    $("#date_calendar").datepicker(
  { 
        changeMonth: true,
        changeYear: true,
        dateFormat: 'yy-mm-dd',
        defaultDate: $.datepicker.parseDate("y-m-d", $('#date').val()),
        onSelect: function(dateText, inst)
            {
                alert('onSelect triggered! Yay!');
                $('#date').val($.datepicker.formatDate("yy-mm-dd", $('#date_calendar').datepicker('getDate')));

                // Ajax for populating days when selected
                $.post(
                    "server_requests/show_day.php",
                        {
                        date: $('#date').val(),
                        user_id: $('#user_id').val()
                        },
                    function(data)
                    {
                        //return function
                        $('#my_day_tasks').html(data.resultTable);
                    },
                    "json"
                );
            }
    }).disableSelection();

    $("#date_calendar").trigger('onSelect');

});

推荐答案

你不能将它重构为自己的功能，您重新使用它？严格来说，datepicker选择不是真的页面加载会发生什么。你只是想做完全同样的事情，当确实选择了datepicker。

Couldn't you just refactor that to a function of its own, which you reuse? Strictly speaking, a datepicker select is not really what happens on page load. You just want to do exactly the same thing that happens when the datepicker is indeed selected.

function populateList(dateText, inst)
{
    alert('alert test');
    $('#date').val($.datepicker.formatDate("yy-mm-dd",$('#date_calendar').datepicker('getDate')));

    // Ajax for populating days when selected
    $.post("server_requests/show_day.php",
        {
            date: $('#date').val(),
            user_id: $('#user_id').val()
        },
        function(data)
        {
            //return function
            $('#my_day_tasks').html(data.resultTable);
        },
        "json"
    );
}

$(document).ready(function(){
  //create date pickers
  $("#date_calendar").datepicker(
  { 
        changeMonth: true,
        changeYear: true,
        dateFormat: 'yy-mm-dd',
        defaultDate: $.datepicker.parseDate("y-m-d", $('#date').val()),
        onSelect: populateList
  }).disableSelection();

  // i'm not bothering to pass the input params here, because you're not using them anyway
  populateList(); 

});
