问题描述
我正在使用Trent Richardson的jQuery UI Timepicker.我知道插件已被修改以覆盖$ .datepicker._selectDate,以便选择器在选择日期时将保持打开状态.太好了.
I am using Trent Richardson's jQuery UI Timepicker. I know the plugin has been modified to override $.datepicker._selectDate so that the picker will stay open when a date is selected. That's great.
但是,我被要求在双击日期时关闭选择器.其他所有内容都保持不变,包括一个用于在完成后关闭选择器的按钮,等等,只是他们希望双击也能正常工作.
However, I have been asked to have the picker close when double-clicking a date. Everything else remains the same, including a button for closing the picker when done, etc., only they want the double-click to work as well.
我试图以多种方式将双击事件绑定到日历日期(主要是$('.ui-datepicker-calendar a').bind('dblclick', function () {/*do something*/});)
的变体-实际上,我也试图绑定其他事件-似乎没有任何效果.针对如何通过双击关闭DateTimePicker 的建议没有喜悦.
I have attempted to bind the double-click event to calendar dates in several ways (mostly variations of $('.ui-datepicker-calendar a').bind('dblclick', function () {/*do something*/});)
-- indeed, I have attempted to bind other events as well -- and nothing seems to work. I have tried the suggestions posted for How to close DateTimePicker with a double click with no joy.
这甚至有可能吗?我是否需要修改onSelect函数以区分单击和双击? (并且,当event.type
未定义时如何?)我是否绑定到错误的元素? (我尝试在$('.ui-datepicker-calendar a')
,$('#ui-datepicker-div')
,$('#ui-datepicker-div .ui-datepicker-calendar a')
以及许多其他变体上进行绑定.)
Is this even possible? Do I need to modify the onSelect function to distinguish between a click and a double-click? (And how, when event.type
is undefined?) Am I binding to the wrong element? (I've attempted binds on $('.ui-datepicker-calendar a')
, $('#ui-datepicker-div')
, $('#ui-datepicker-div .ui-datepicker-calendar a')
, and numerous other variations.)
为了完整起见,这是我的代码:
For the sake of completeness, here's my code:
$('#date-range-from, #date-range-to').datetimepicker({
changeYear: true,
changeMonth: true,
controlType: 'select',
dateFormat: 'M dd, yy ',
minDate: 'Jan 01, 2010 ',
maxDate: 'Dec 31, xxxx '.replace('xxxx', new Date().getFullYear() + 1),
showAnim: '',
showMinute: false,
showOtherMonths: true,
showTime: false
}).on('change', function () {
var t = $(this),
date = t.val().slice(0, 12),
fromto = t.attr('id').replace('date-range-', ''),
time = t.val().slice(-5);
dashboardOpts.dateRange[fromto].date = date;
dashboardOpts.dateRange[fromto].time = time;
}).mousedown(function () {
$('#ui-datepicker-div').toggle();
$(this).blur();
});
$('#ui-datepicker-div .ui-datepicker-calendar a').bind('dblclick', function () {
console.log('I just want to see if this event can be bound!');
});
在此先感谢您的帮助!
为了澄清起见,通过"... ... c5>的变化",我的意思是我尝试了.live('dblclick', ...)
(即使我知道它已被弃用),$(element).on('dblclick', ...)
和$(document).on('dblclick', element, ...)
For clarification, by "variations of ... .bind('dblclick', ...)
" I meant that I tried .live('dblclick', ...)
(even though I know it's deprecated) and $(element).on('dblclick', ...)
and $(document).on('dblclick', element, ...)
.
即使我不认为这是传播问题,我也尝试了.stopPropagation()
和.stopImmediatePropagation()
.
I have also attempted to .stopPropagation()
and .stopImmediatePropagation()
even though I do not believe this is a propagation issue.
我相信datetimepicker插件的代码中有某些东西在劫持日历中的事件.不幸的是,我还没有找到它.非常感谢任何见识!
I believe there is something in the datetimepicker plugin's code that is hijacking events in the calendar. Unfortunately, I have not yet been able to find it. Any insight is much appreciated!
推荐答案
在datetimepicker的源代码中,您可以看到作者在选择日期后使用hack来禁用关闭.他自称是不好的hack.
In datetimepicker's source, you can see author use an hack to disable closing when a date is selected. He calls it himself a bad hack.
无论如何,这是一种解决方法,可以在双击日期时关闭日期选择器.我使用onSelect
函数回调:
Anyway, here is a workaround to able datepicker be closed when you double click on a date.I use onSelect
function callback:
$('#mydatepicker').datetimepicker({
onSelect: function (e, t) {
if (!t.clicks) t.clicks = 0;
if (++t.clicks === 2) {
t.inline = false;
t.clicks = 0;
}
setTimeout(function () {
t.clicks = 0
}, 500);
}
});
因此,在某种程度上,我使用超时来模拟dblclick行为.我将其设置为500ms,但是如果您希望dblclick或多或少敏感,就可以使用它.
So, in some way, i simulate dblclick behaviour using a timeout. I set it to 500ms but just play with this if you wish your dblclick to be more or less sensitive.
更新
@JaredKnipp似乎在切换月份时将焦点设置为输入(无效???),我没有足够的时间来详细检查它,对不起.作为一个简单的解决方法,您可以尝试按照以下代码段,将其添加到endDateTextBox onClose回调中:
@JaredKnipp It appears that focus is set to input when month is switched (unvalid???), i don't have enough time to check it in detail, i'm sorry. As a simple workaround, you could try following snippet, add it to endDateTextBox onClose callback:
var focusHandlers = $._data(endDateTextBox[0], "events").focus;
$._data(endDateTextBox[0], "events").focus = {};
endDateTextBox.one('focusin.datetimepicker mouseenter.datetimepicker', function () {
setTimeout(function () {
$._data(endDateTextBox[0], "events").focus = focusHandlers;
endDateTextBox.blur();
}, 0);
$(this).off('focusin.datetimepicker mouseenter.datetimepicker');
});
请注意,如果您使用的是1.8之前的jq版本,则必须使用$.data()
而不是$._data()
希望对您有所帮助...
Note that if you are using jq version prior to 1.8, you have to use $.data()
not $._data()
Hope it helps...
