我在我的应用上使用'flatpickr'作为日期时间选择器。此日期选择器允许选择多个日期,但在阅读文档后,我找不到任何方法来限制所选日期的最大数量。
Jquery的:
function doSelect(text) {
return $(".infobox th").filter(function() {
return $(this).text() === text;
});
}
countryLinks = doSelect("Location").siblings('td')
.find('a').map(function(i, el) {return el.href}).get(); // .attr('href');
// we can pass this function to `.forEach()` or `.map()`
function countryList(string) {
let pattern = new RegExp('^.+\/wiki\/'); // adjust `RegExp`
// string = countryLinks;
countryListLinks = string.replace(pattern, '');
console.log(countryListLinks);
}
// the second condition is `false` given HTML at Question
if (doSelect('Location').length > 0 /* && doSelect('Date').length > 0 */) {
countryLinks.forEach(countryList);
};
这里当选择了3个日期时,控制台输出“你已经达到了你的极限”,我想也许我可以在发生这种情况时禁用所有日期(除了之前选择的日期)。
Flatpickr有一个<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="infobox">
<tr>
<th style="padding-right:1em">Location</th>
<td>
<span class="location">Lower reaches of the <a href="/wiki/Geum_River" title="Geum River">Geum River</a>, <a href="/wiki/Korea" title="Korea">Korea</a></span>
</td>
</tr>
</table>
和$('#gig_date_multi').flatpickr({
"mode": "multiple",
"locale": "<%= I18n.locale %>",
minDate: new Date(),
enableTime: true,
time_24hr: true,
minuteIncrement: 15,
onChange: function(selectedDates, dateStr, instance) {
var array = selectedDates;
if (array.length >= 3) {
console.log("YOU HAVE REACHED YOUR LIMIT")
} else {
console.log("YOU CAN STILL SELECT MORE DATES")
}
var newHTML = [];
$.each(array, function(index, value) {
var formatted = moment(value).format("HH:mm - dddd Do MMMM YYYY");
newHTML.push('<span>' + formatted + '</span>');
});
$(".multi-dates").html(newHTML.join(""));
}
});
函数,但我不确定如何将它集成到代码中...我是一个jquery初学者。
文档显示了这两种方法;
disable
和
enable

您可以使用:
set(option, value):将配置选项设置为值,重新绘制日历并更新当前视图(如有必要)
为了禁用除3个所选日期以外的所有日期,您可以写:
instance.set('enable', selectedDates);
并且,为了重置你可以:
instance.set('enable', []);
另一种方法可以基于Enabling dates by a function:
instance.set('enable', [function(date) {
if (selectedDates.length >= 3) {
var currDateStr = FlatpickrInstance.prototype.formatDate(date, "d/m/Y")
var x = selectedDatesStr.indexOf(currDateStr);
return x != -1;
} else {
return true;
}
}]);
摘录:
$('#gig_date_multi').flatpickr({
"mode": "multiple",
"locale": 'en',
minDate: new Date(),
enableTime: true,
time_24hr: true,
minuteIncrement: 15,
onChange: function(selectedDates, dateStr, instance) {
var selectedDatesStr = selectedDates.reduce(function(acc, ele) {
var str = FlatpickrInstance.prototype.formatDate(ele, "d/m/Y");
acc = (acc == '') ? str : acc + ';' + str;
return acc;
}, '');
instance.set('enable', [function(date) {
if (selectedDates.length >= 3) {
var currDateStr = FlatpickrInstance.prototype.formatDate(date, "d/m/Y")
var x = selectedDatesStr.indexOf(currDateStr);
return x != -1;
} else {
return true;
}
}]);
}
});

附带说明,如果有人想在 Flatpickr 中禁用过去日期和时间 选择,请像这样使用 Date().getTime()
:
$("input.picker-datetime").flatpickr({
enableTime: true,
dateFormat: "Y-m-d H:i",
time_24hr: true,
minDate: new Date().getTime()
});
