扩展输入时隐藏标题，输入最小化时显示标题

标签： javascript jquery html css material-design

我有一个示例代码，显示带有css动画的搜索查询。

我想知道，如何在展开搜索查询时隐藏“标题”类，并在搜索查询最小化时再次显示它？

以下是两种状态的示例图像（正如您可以看到“标题”可在搜索文本后面查看，我不想要）：

enter image description here

我知道在jquery中我可以像这样隐藏它（再次显示它我不知道逻辑会如何）：

$("p").hide();

但我怎么能用CSS做到这一点？

该代码片段正在运行，但它无法正常显示，但我不知道原因。

$('.opener').click(function() {
  $(this).parent('.search').toggleClass('inactive').find('input').focus();
});
.row {
  border: 1px solid red;
}

.title {
  font-size: 16px;
  font-weight: bold;
  position: absolute;
  margin: 6px 0;

.input-group {
  display: flex;

}

您可以使用siblings选择div.title。 使用display：none属性添加另一个类并切换该类

＆＃13;
＆＃13; 
$("p").hide();
$('.opener').click(function() {
  $(this).parent('.search').toggleClass('inactive').find('input').focus();
  $(this).parent('.search').siblings('div.title').toggleClass('hideTitle')
});
＆＃13; 
.row {
  border: 1px solid red;
}

.title {
  font-size: 16px;
  font-weight: bold;
  position: absolute;
  margin: 6px 0;
}

.input-group {
  display: flex;
  height: 36px;
  width: 100%;
  overflow: hidden;
  padding: 0;
  /*background-color: rgba(100, 100, 100, .1);*/
  cursor: pointer;
  /*border-radius: 2px;*/
  transition: all 0.3s cubic-bezier(0.25, 0.8, 0.25, 1);
  /*box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24);*/
}

.input-group:active,
.input-group:hover {
  /*background-color: rgba(100, 100, 100, .1);*/
}

.input-group.centered {
  margin: 0 auto;
}

.input-group .input-group-addon {
  justify-content: center;
  width: 36px;
  background: transparent;
  border: none;
  display: flex;
  text-align: center;
  transition: all 0.3s cubic-bezier(0.25, 0.8, 0.25, 1);
}

.input-group .input-group-addon i {
  height: 24px;
  width: 24px;
  align-self: center;
  color: #777;
}

.input-group input {
  font-family: "Roboto", sans-serif;
  background: transparent;
  border: none;
  box-shadow: none !important;
  font-size: 16px;
  padding: 0;
}

.inactive {
  width: 36px;
  border-radius: 18px;
  background: transparent;
  box-shadow: none;
}

.inactive .input-group-addon:not(:first-child) {
  opacity: 0;
}

.row {
  margin-top: 1em;
}
.hideTitle{
 display:none;

将标签和输入包含在一个div中，位置相对并使用siblings jquery来隐藏标题

＆＃13;
＆＃13; 
$('.opener').click(function() {
  $(this).parent('.search').toggleClass('inactive').find('input').focus();
  $(this).parent('.search').siblings('label').toggleClass('hide');
});
＆＃13; 
.row {
  border: 1px solid red;
}
.search-form {
  position:relative;
}

.search-form .title {
  font-size: 16px;
  font-weight: bold;
  position: absolute;
  margin: 6px 0;
}

.input-group {
  display: flex;
  height: 36px;
  width: 100%;
  overflow: hidden;
  padding: 0;
  /*background-color: rgba(100, 100, 100, .1);*/
  cursor: pointer;
  /*border-radius: 2px;*/
  transition: all 0.3s cubic-bezier(0.25, 0.8, 0.25, 1);
  /*box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24);*/
}

.input-group:active,
.input-group:hover {
  /*background-color: rgba(100, 100, 100, .1);*/
}

.input-group.centered {
  margin: 0 auto;
}

.input-group .input-group-addon {
  justify-content: center;
  width: 36px;
  background: transparent;
  border: none;
  display: flex;
  text-align: center;
  transition: all 0.3s cubic-bezier(0.25, 0.8, 0.25, 1);
}

.input-group .input-group-addon i {
  height: 24px;
  width: 24px;
  align-self: center;
  color: #777;
}

.input-group input {
  font-family: "Roboto", sans-serif;
  background: transparent;
  border: none;
  box-shadow: none !important;
  font-size: 16px;
  padding: 0;
}

.inactive {
  width: 36px;
  border-radius: 18px;
  background: transparent;
  box-shadow: none;
}

.inactive .input-group-addon:not(:first-child) {
  opacity: 0;
}

.row {
  margin-top: 1em;
