jquery - 从多个li中选择同一个孩子

问题描述

我已经从 ul 和 li 列表中构建了表格。我现在想通过更改所有行内 li 的类来切换 li“单元格”的类，但来自多个 div 的同一个子项，以便给出高亮行的样式。

  1. 单击 li 孩子更改所有列表中相同 li 孩子的班级
  2. 在所有列表中的 li 孩子的悬停上更改同一 li 孩子的班级

影响在单击和悬停时突出显示“行”。

为清楚起见，请参阅下面的基本大纲。

我的代码

$("#cell").hover(function() {
  (".cd-features-list li").addClass("cellHover");
});

$("#cell").click(function() {
  (".cd-features-list li").addClass("cellClick");
});
    .cellHover {
  background: #888;
  ) .cellClick {
    background: #111;
    )

解决方案

在这里使用这个 jsfiddle

$( ".cd-features-list > li" ).hover(
  function() { 
  var u=$(this).parent('ul');
   $(u).addClass("cellHover");
  }, function() {
   var u=$(this).parent('ul');
   $(u).removeClass("cellHover");
   
  }
);

$( ".cd-features-list li" ).click(function() { 
 var u=$(this).parent('ul');
   $(u).addClass("cellClick");
  }
);
 .cellHover {
  background-color: #666666;
  }
  .cellClick {
    background: #111;
    }
