jquery - 从多个 li 中选择同一个 child

Question

我已经从 ul 和 li 列表构建了表格。我现在想切换 li“单元格”的类，但来自多个 div 的同一个子项，以便通过更改所有行内 li 的类来使 highling 的样式连续。

1. 点击 li child 更改所有列表中同一个 li child 的类(class)
2. 悬停 li child 在所有列表中更改同一个 li child 的类

影响在点击和悬停时突出显示“行”。

为了清楚起见，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;
    )

Answer 1

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;
    }
