在jQuery UI datepicker中显示日期旁边的其他文本 [英] Display additional text alongside dates in jQuery UI datepicker

问题描述

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：

I am using jQuery UI datepicker and I want to display additional text inside date cells next to the date. This is the desired behavior:

不幸的是，操纵日期使用 .text（）和 .html（）函数的单元格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（ii）更改月份会破坏日历并让您登录未定义的NaN月份：

Unfortunately, manipulating date cells using .text() and .html() functions breaks the datepicker functionality. See following demo and try to use the datepicker. Notice that when you select a date (i) the custom text is gone (ii) changing months destroys the calendar and lands you on "undefined NaN" month:

有吗一个解决方案？

推荐答案

那么，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回调将自定义数据 - * 属性添加到datepicker并使用 CSS伪元素：

Well, you can monkey-patch jQuery UI and risk breaking the code with newer versions or you can use documented callbacks to add custom data-* attributes to datepicker and display them using CSS pseudo elements:

$(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)
}

.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;
}

<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">

Side注意：我不确定你的演示中有哪些功能被破坏，但由于这个解决方案使用了文档化的回调和CSS，我相信它不太可能在将来破坏任何东西而不是猴子修补

Side note: I'm not sure which functionality is broke in your demo, but since this solution is using documented callbacks and CSS, I believe it's less likely to break anything in future than monkey patching
