Answer 1

将.eq()与.index()
一起使用

$('.uprow .menu').on('click', function() {
  $('.downrow .pipe').eq($(this).index()).css('width', '100%')
})

.leftbox {
  width: 100px;
  height: 400px;
  background-color: lightgreen;
  display: -webkit-flex;
  display: flex;
  -webkit-flex-direction: row;
  flex-direction: row;
}
.uprow {
  width: 100px;
  height: 100%;
  background-color: pink;
  display: -webkit-flex;
  display: flex;
  -webkit-flex-direction: column;
  flex-direction: column;
  -webkit-justify-content: space-around;
  justify-content: space-around;
}
.menu {
  width: 50px;
  height: 50px;
  background-color: yellow;
}
.selected {
  background-color: green;
  border: 2px solid blue;
}
.downrow {
  width: 100%;
  height: 100%;
  background-color: gray;
  display: -webkit-flex;
  display: flex;
  -webkit-flex-direction: column;
  flex-direction: column;
  -webkit-justify-content: space-around;
  justify-content: space-around;
}
.pipe {
  width: 10%;
  height: 5px;
  background-color: aqua;
}

Answer 2

您可以使用所选元素的click事件，如下所示。

在下面的示例中，单击任何元素将仅将该元素的宽度更改为100％。

＆＃13;

$(function() {
  $('.pipe').click(function() {
    /* $(this) is the clicked/selected object. */
    /* Do your required action using $(this). Below is an example */
    $(this).css('width', '100%');
  });
});

＆＃13;

.leftbox {
  width: 100px;
  height: 400px;
  background-color: lightgreen;
  display: -webkit-flex;
  display: flex;
  -webkit-flex-direction: row;
  flex-direction: row;
}
.uprow {
  width: 100px;
  height: 100%;
  background-color: pink;
  display: -webkit-flex;
  display: flex;
  -webkit-flex-direction: column;
  flex-direction: column;
  -webkit-justify-content: space-around;
  justify-content: space-around;
}
.menu {
  width: 50px;
  height: 50px;
  background-color: yellow;
}
.selected {
  background-color: green;
  border: 2px solid blue;
}
.downrow {
  width: 100%;
  height: 100%;
  background-color: gray;
  display: -webkit-flex;
  display: flex;
  -webkit-flex-direction: column;
  flex-direction: column;
  -webkit-justify-content: space-around;
  justify-content: space-around;
}
.pipe {
  width: 10%;
  height: 5px;
  background-color: aqua;
}
