JQuery Datepicker - 垂直居中日期

Question

我目前正在为 jquery datepicker 设置样式，但我正在努力将日期位置垂直居中。

这是我目前得到的： https://jsfiddle.net/L4vrkpmc/1/

由于日期选择器使用的是我尝试过的表

.ui-datepicker-calendar td{
  vertical-align:center;
}

但它不会工作。有人知道如何垂直居中日期吗？

感谢您的帮助:)

Answer 1

如果“a”标签中不包含任何子标签，则不能垂直对齐文本。我使用 jQuery 在“a”标签下用<span> 包裹了文本。这是代码：

$(".ui-datepicker td").each(function(){
    var dateText = $(this).find("a").text();
    $(this).find("a").html("<span>"+dateText+"</span>");
});

还有一些简单的 CSS 更改：

.ui-datepicker td a{
    display: table;
    position: relative;
    height: 100%;
    width: 100%;
}
.ui-datepicker td a span{
    display: table-cell;
    text-align:center;
    vertical-align: middle;
}

您可以使用仅使用 CSS 来实现此目的，只需将数字的 line-height 设置为与正方形的相同高度：

.ui-state-default {
    height: 45px;
    line-height: 45px;
    padding: 0;
}
