Question

我的目标是能够在点击时突出显示单元格，并在再次单击时取消突出显示。

每行只能突出显示一个单元格。

以下是我尝试过的代码，这里是fiddle。

感谢。

HTML：

<div class="hws-css-filter" >
  <div class="hws-css-filter-tr">
    <div class="hws-css-filter-td"></div>
    <div class="hws-css-filter-td"></div>
    <div class="hws-css-filter-td"></div>
  </div>
  <div class="hws-css-filter-tr">
    <div class="hws-css-filter-td"></div>
    <div class="hws-css-filter-td"></div>
    <div class="hws-css-filter-td"></div>
  </div>
</div>

的jQuery

$('.hws-css-filter-td').click(function () {
    var theTable = $(this).closest('.hws-css-filter-tr');
    $(theTable).each(function () {
        $(this).css("background-color", "");
    });
    $(this).css("background-color", "blue");
});

首先删除所有兄弟姐妹的背景颜色，如下所示。

＆＃13;

$('.hws-css-filter-td').click(function() {
  $(this).siblings().css("background-color", "");
  $(this).css("background-color", "blue");
});

＆＃13;

.hws-css-filter {
  display: table;
  margin: auto;
  vertical-align: middle;
}

.hws-css-filter-tr {
  display: table-row;
  padding: 0;
  margin: 0;
}

.hws-css-filter-td {
  display: table-cell;
  border: 1px solid #000;
  width: 15px;
  height: 15px;
  line-height: 15px;
  text-align: center;
  vertical-align: middle;
  padding: 0;
  margin: 0;
  font-family: monospace;
  font-size: 10px;
  text-transform: uppercase;
  cursor: pointer;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="hws-css-filter">
  <div class="hws-css-filter-tr">

更新：选择未选中。

＆＃13;

$('.hws-css-filter-td').click(function() {
  $(this).siblings().removeClass('selected');
  $(this).toggleClass('selected');
});

＆＃13;

.hws-css-filter {
  display: table;
  margin: auto;
  vertical-align: middle;
}

.hws-css-filter-tr {
  display: table-row;
  padding: 0;
  margin: 0;
}

.hws-css-filter-td {
  display: table-cell;
  border: 1px solid #000;
  width: 15px;
  height: 15px;
  line-height: 15px;
  text-align: center;
  vertical-align: middle;
  padding: 0;
  margin: 0;
  font-family: monospace;
  font-size: 10px;
  text-transform: uppercase;
  cursor: pointer;
}

.selected {
  background-color: blue;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Answer 2

为了更好地管理单元格格式，请为突出显示的单元格创建新样式

.cell_highlight{
    background-color: blue;
}

并设置jQuery事件：

$('.hws-css-filter-td').click(function () {
    $(this).siblings().removeClass("cell_highlight"); 
    $(this).addClass("cell_highlight");
});

Answer 3

这将满足您的所有要求：

点击
如果再次点击则取消突出显示
每行只允许一个突出显示的单元格

$('.hws-css-filter-td').on('click', function() {
  var $this = $(this);
  
  if ($this.hasClass('blue-highlight')) {
    $this.removeClass('blue-highlight');
  } else {
    $this.addClass('blue-highlight');
    $this.siblings().removeClass('blue-highlight');
  }
});

.hws-css-filter-td {
  border: solid 1px #000;
  height: 25px;
  width: 25px;
  float: left;
}

.hws-css-filter-tr {
  clear: left;
}

.blue-highlight {
  background-color: blue;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="hws-css-filter" >
  <div class="hws-css-filter-tr">
    <div class="hws-css-filter-td"></div>
    <div class="hws-css-filter-td"></div>
    <div class="hws-css-filter-td"></div>
  </div>
  <div class="hws-css-filter-tr">
    <div class="hws-css-filter-td"></div>
    <div class="hws-css-filter-td"></div>
    <div class="hws-css-filter-td"></div>
  </div>
</div>

Answer 4

基于Figor的答案，但也切换突出显示的单元格 https://jsfiddle.net/dwsL9z63/5/

   $('.hws-css-filter-td').click(function () {
      if($(this).hasClass("cell_highlight")){
        $(this).removeClass("cell_highlight");
      }
      else{
         $(this).addClass("cell_highlight");
      }

      $(this).siblings().removeClass("cell_highlight");

   });

每行只突出显示一个单元格
