单击复选框有时会切换其他复选框

Question

所以我得到了5 ╦═════════════════════╦═════════════════════════╗ ║ Falsy ║ Truthy ║ ╠═════════════════════╬═════════════════════════╣ ║ 0 ║ Non-0 ║ ║ @() ║ @(1) ║ ║ @(0) ║ @(0, 1) ║ ║ [string]::Empty ║ Non-empty string ║ ║ $false ║ $true ║ ║ 0-backed enum value ║ Any non-0 enum value ║ ║ $null ║ Any non-$null reference ║ ╚═════════════════════╩═════════════════════════╝ 。所有下面一个。它们是使用checkbox和svg制作的。当我单击每个复选框的标签时，它会切换正确的复选框，但是当我单击复选框的图像时，有时它会切换不正确的复选框！

.cbx {
  margin: auto;

  -webkit-user-select: none;
  user-select: none;
  cursor: pointer;

.cbx span {
  display: inline-block;

.cbx span:first-child:before {

  width: 100%;
  height: 100%;
  background: #506EEC;
  display: block;
  transform: scale(0);
  opacity: 1;
  border-radius: 50%;
}
.cbx span:last-child {
  padding-left: 8px;
}
.cbx:hover span:first-child {
  border-color: #506EEC;
}

.inp-cbx:checked + .cbx span:first-child {
  background: #506EEC;
  border-color: #506EEC;
  animation: wave 0.4s ease;
}
.inp-cbx:checked + .cbx span:first-child svg {
  stroke-dashoffset: 0;
}
.inp-cbx:checked + .cbx span:first-child:before {
  transform: scale(3.5);
  opacity: 0;
  transition: all 0.6s ease;
}

@keyframes wave {
  50% {
    transform: scale(0.9);
  }
}

选择复选框1、2、3、4。然后单击复选框3取消选中它。复选框4变为未选中状态。再次单击复选框3时，将其取消选中。

Answer 1

因为transform：在选中时scale（3.5）会扩大其大小并覆盖其他复选框，这就是为什么。

.inp-cbx:checked + .cbx span:first-child:before {
  transform: scale(1); // set scale to it's actual size instead of 3.5
  opacity: 0;
  transition: all 0.6s ease;
}

  -webkit-user-select: none;

Answer 2

将指针事件都不添加到跨度似乎是可行的解决方法

.cbx span {
  pointer-events: none;
}

Answer 3

您可以使用值标签。

<input id="1" value="test" ../>
<input id="3" value="test" ../>

Answer 4

将变换属性值更改为1.5

.inp-cbx:checked + .cbx span:first-child:before {
   transform: scale(1.5);
   opacity: 0;
   transition: all 0.6s ease;
}

Answer 5

将pointer-events: none;添加到.cbx span:first-child:before样式中。导致问题的是动画。

在.cbx span:first-child:before中，我们将content:""从scale(0)和opacity:1分别缩放到scale(3.5)和opacity:0。因此，实际上我们只是以不透明的方式隐藏该对象，这意味着该对象将在那里并且可以单击。这就是为什么我们需要在pointer-events:none样式中添加.cbx span:first-child:before。

要对其进行测试，只需选中第4个复选框并以.inp-cbx:checked + .cbx span:first-child:before样式进行检查。将不透明度从0更改为opacity:1。您将看到类似下面的内容。

在上图中，您可以看到第四个复选框的span:before覆盖了第三个复选框。它是可点击的。这就是为什么当您单击第三个复选框时，它实际上会单击第四个复选框。

请参见下面的代码段。
