如何从一系列数据属性的元素中更改css？

我想将数据日期“2018-04-03”中的表格颜色设置为数据日期“2018-04-06”。有没有办法用jquery定义这个数据属性范围。现在我只知道如何为每一行单独着色：

jQuery(document).ready(function() {
  jQuery(".main-table").clone(true).appendTo('#table-scroll').addClass('clone');
});


 $("td[data-row='2'][data-date='2018-04-03']").css({ "background":"lightblue", "border-right-color":"lightblue" })
 $("td[data-row='2'][data-date='2018-04-04']").css({ "background":"lightblue", "border-right-color":"lightblue" })
$("td[data-row='2'][data-date='2018-04-05']").css({ "background":"lightblue", "border-right-color":"lightblue" })
$("td[data-row='2'][data-date='2018-04-06']").css({ "background":"lightblue" })
.table-scroll {
  position: relative;
  margin: auto;
  overflow: hidden;
}

.table-wrap {
  width: 100%;
  overflow: auto;
}

.table-scroll table {
  width: 100%;
  margin: auto;
  border-collapse: separate;
  border-spacing: 0;
}

.table-scroll th,
.table-scroll td {
  padding: 5px 10px;
  white-space: nowrap;
  vertical-align: top;
}

.clone {
  position: absolute;
  top: 0;
  left: 0;
  pointer-events: none;
}

.clone th,
.clone td {
  visibility: hidden
}

.clone td,
.clone th {
  border-color: transparent
}

.clone tbody th {
  visibility: visible;
}

.clone .fixed-side {
  visibility: visible;
  background-color: #fff;
  font-weight: normal;
  border: none;
  border-right: 2px solid #f4f4f4;
}

.clone thead,
.clone tfoot {
  background: transparent;
}

.gantt-h {
  font-weight: normal;
  color: #b0b0b0;
  border-right: 2px solid #f4f4f4;
}

.last {
  border-right: 2px solid #f4f4f4;
}

.gantt td {
  border-right: 2px solid #f4f4f4;
}

for循环将帮助您完成此操作。

var dates = ['2018-04-03','2018-04-04','2018-04-05','2018-04-06'];
for(var i=0; i<dates.length; i++){
$("td[data-date='"+dates[i]+"']").css({ "background":"lightblue" })
}

答案 1 :(得分：1)

至少，您可以将它们组合成一个选择器：

$("td[data-row='2'][data-date='2018-04-03'],td[data-row='2'][data-date='2018-04-04']")
    .css({ "background":"lightblue", "border-right-color":"lightblue" })

然后可以使用.filter()

缩小 
$("td[data-row='2']").filter("[data-date='2018-04-03'],[data-date='2018-04-04']")
    .css({ "background":"lightblue", "border-right-color":"lightblue" })

鉴于范围不会被修复，你可以使用循环构建选择器（以创建一个巨大的选择器字符串），或者你可以遍历这些值，例如：

var cells = $("td[data-row='2']");

var start = new Date("2018-05-28");
var end = new Date("2018-06-02");
var newend = end.setDate(end.getDate()+1);
var end = new Date(newend);
while(start < end){
    var datadate = start.toISOString().split('.')[0]+"Z";

    cells.filter("[data-date='" + datadate + "']").css({ "background":"lightblue", "border-right-color":"lightblue" })

    var newDate = start.setDate(start.getDate() + 1);
    start = new Date(newDate);
}

（循环来源：Javascript - get array of dates between 2 dates）

最后一个选择是应用＆＃39;比较＆＃39;在过滤器中，类似：

var start = new Date("2018-05-28");
var end = new Date("2018-06-02");

$("td[data-row='2']").filter(function() {
    var thisdate = $(this).data("date");
    return (thisdate > start && thisdate <= end);
}).css({"background":"lightblue", "border-right-color":"lightblue"})

顺便说一句，你最好不要直接使用类而不是直接设置css属性。
