JQuery Datepicker,不能手动触发onSelect事件! [英] JQuery Datepicker, can't trigger onSelect event manually!
问题描述
我正在使用 jquery 的 datepicker,只要从内联 datepicker 对象中选择日期,就会从 ajax 调用填充项目列表.该脚本运行良好,只是我无法触发 onSelect 事件来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.
我可以通过最初使用 php 填充列表来解决这个问题,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
你不能把它重构为一个你自己的函数,你可以重用它吗?严格来说,日期选择器选择并不是真正在页面加载时发生的.您只想做与确实选择了日期选择器时完全相同的事情.
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();
});
