我正在使用jQuery UI datepicker,我希望在日期旁边的日期单元格中显示其他文本。这是理想的行为:
不幸的是,使用.text()
和.html()
函数操作日期单元会破坏日期选择器功能。请参阅以下演示并尝试使用datepicker。请注意,当您选择日期时(i)自定义文本消失了(ii)更改月份会破坏日历并让您登录“未定义的NaN”月份:

有解决方案吗?

好吧,你可以修补jQuery UI并冒险破坏新版本的代码,或者你可以使用文档化的回调将自定义data-*
属性添加到datepicker并使用CSS pseudo elements显示它们:
$(function() {
$("#datepicker").datepicker({
beforeShow: addCustomInformation,
//---^----------- if closed by default (when you're using <input>)
beforeShowDay: function(date) {
return [true, date.getDay() === 5 || date.getDay() === 6 ? "weekend" : "weekday"];
},
onChangeMonthYear: addCustomInformation,
onSelect: addCustomInformation
});
addCustomInformation(); // if open by default (when you're using <div>)
});
function addCustomInformation() {
setTimeout(function() {
$(".ui-datepicker-calendar td").filter(function() {
var date = $(this).text();
return /\d/.test(date);
}).find("a").attr('data-custom', 110); // Add custom data here
}, 0)
}
&#13;
.ui-datepicker .weekend .ui-state-default {
background: #FEA;
}
.ui-datepicker-calendar td a[data-custom] {
position: relative;
padding-bottom: 10px;
}
.ui-datepicker-calendar td a[data-custom]::after {
/*STYLE THE CUSTOME DATA HERE*/
content: '$' attr(data-custom);
display: block;
font-size: small;
}
&#13;
<script src="//code.jquery.com/jquery-1.9.1.min.js"></script>
<link href="//code.jquery.com/ui/1.9.2/themes/smoothness/jquery-ui.css" rel="stylesheet" />
<script src="//code.jquery.com/ui/1.9.2/jquery-ui.min.js"></script>
<input id="datepicker">
&#13;
这是一个更新的JSFiddle
附注:我不确定您的演示中哪个功能已经破坏,但由于此解决方案使用了文档化的回调和CSS,我相信它在未来打破任何东西的可能性都小于猴子补丁< / p>

由于jQuery UI数据采集器非常单一,因此很难干净地增强。
我会使用猴子修补其内部函数之一,即_generateHTML
。
$.datepicker._generateHTML = (function () {
var realGenerateHtml = $.datepicker._generateHTML;
return function (instance) {
var html = realGenerateHtml.apply(this, arguments), $temp;
if ( instance.input.is(".datepicker-price") ) {
$temp = $("<table></table>").append(html);
$temp.find(".ui-datepicker-calendar td a").each(function () {
var yy = $(this).parent().data("year"),
mm = $(this).parent().data("month"),
dd = +$(this).text();
$(this).append("<br><small class='price'>$100</small>");
});
html = $temp[0].innerHTML;
}
return html;
};
})();
$(function() {
$("#datepicker").datepicker();
});
&#13;
.ui-datepicker .weekend .ui-state-default {
background: #FEA;
}
.price {
color: blue;
}
&#13;
<link href="https://code.jquery.com/ui/1.9.2/themes/smoothness/jquery-ui.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.9.2/jquery-ui.min.js"></script>
<div id="datepicker" class="datepicker-price"></div>

基于the accepted answer有一个更简单的解决方案:
beforeShowDay
功能允许我们为每个日期设置“标题”属性。我们可以使用CSS伪元素显示属性。
$(function() {
var dayrates = [100, 150, 150, 150, 150, 250, 250];
$("#datepicker").datepicker({
beforeShowDay: function(date) {
var selectable = true;
var classname = "";
var title = "\u20AC" + dayrates[date.getDay()];
return [selectable, classname, title];
}
});
});
@import url("https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/blitzer/jquery-ui.min.css");
.ui-datepicker td span,
.ui-datepicker td a {
padding-bottom: 1em;
}
.ui-datepicker td[title]::after {
content: attr(title);
display: block;
position: relative;
font-size: .8em;
height: 1.25em;
margin-top: -1.25em;
text-align: right;
padding-right: .25em;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<div id="datepicker"></div>

将此代码添加到您的JS ...
$('#DatePicker').datepicker({
changeMonth: true,
changeYear: true,
minDate: 0,
onSelect: function (date, dp) {
updateDatePickerCells();
},
onChangeMonthYear: function(month, year, dp) {
updateDatePickerCells();
},
beforeShow: function(elem, dp) {
updateDatePickerCells();
}});
updateDatePickerCells();
function updateDatePickerCells(dp) {
setTimeout(function () {
var cellContents = {1: '20', 15: '60', 28: '$99.99'};
$('.ui-datepicker td > *').each(function (idx, elem) {
var value = '$125';//cellContents[idx + 1] || 0;
var className = 'datepicker-content-' + CryptoJS.MD5(value).toString();
if(value == 0)
addCSSRule('.ui-datepicker td a.' + className + ':after {content: "\\a0";}'); //
else
addCSSRule('.ui-datepicker td a.' + className + ':after {content: "' + value + '";}');
$(this).addClass(className);
});
}, 0);
}
var dynamicCSSRules = [];
function addCSSRule(rule) {
if ($.inArray(rule, dynamicCSSRules) == -1) {
$('head').append('<style>' + rule + '</style>');
dynamicCSSRules.push(rule);
}
}
