单击链接名称时如何更改复选标记的颜色

标签: html css

我有以下锚标记,它们动态嵌入到<ul>标记,当用户点击单词TEST我希望复选标记将颜色更改为蓝色时,我尝试了以下但是它不起作用,是什么我做错了吗?

.checkmark{
display: inline-block;
    width: 22px;
    /* height: 22px; */
    height: 17px;
    -ms-transform: rotate(45deg);
    -webkit-transform: rotate(45deg);
    transform: rotate(45deg);
    margin-left: 50%;
    margin-bottom: 1px;
}
.checkmark:before {
    content: '';
    position: absolute;
    width: 3px;
    height: 9px;
    background-color: #ccc;
    left: 11px;
    top: 6px;
}

.checkmark {
    cursor: pointer;
}

 .checkmark:after {
        content: '';
        position: absolute;
        width: 3px;
        height: 3px;
        background-color: #ccc;
        left: 8px;
        top: 12px;
    }

input[type="checkbox"]:checked + .checkmark:before,
input[type="checkbox"]:checked + .checkmark:after {
    background-color: blue;
}
<a class="internal" data-destination="local" dataid="66027" data-nodeid="undefined" ><span><input type="checkbox" style="display:none;" id="cb66027 "></span>TEST<label for="cb66027" class="checkmark"></label></a>

<a>缠绕<input>,点击后不会切换选中的状态。您应该将<a>转换为<label>

这意味着您当前的.checkmark标签需要是另一个元素。我使用了跨度。

您还应将<input>移到其父级<span>之外,以便<input>.checkmark成为兄弟姐妹。

.checkmark {
  display: inline-block;
  width: 22px;
  /* height: 22px; */
  height: 17px;
  -ms-transform: rotate(45deg);
  -webkit-transform: rotate(45deg);
  transform: rotate(45deg);
  margin-left: 50%;
  margin-bottom: 1px;
}

.checkmark:before {
  content: '';
  position: absolute;
  width: 3px;
  height: 9px;
  background-color: #ccc;
  left: 11px;
  top: 6px;
}

.checkmark {
  cursor: pointer;
}

.checkmark:after {
  content: '';
  position: absolute;
  width: 3px;
  height: 3px;
  background-color: #ccc;
  left: 8px;
  top: 12px;
}

input[type="checkbox"]:checked+.checkmark:before,
input[type="checkbox"]:checked+.checkmark:after {
  background-color: blue;
}
&#13;
<label class="internal" data-destination="local" dataid="66027" data-nodeid="undefined">
  <input type="checkbox" style="display:none;" id="cb66027 ">
  TEST
  <span for="cb66027" class="checkmark"></span>
</label>

您使用了错误的def conditional3[U](bool: Boolean, parse: () => Rule1[U]): Rule1[Option[U]] = if (bool) rule { parse() ~> (Some(_: U)) } else rule { push(None) } 选择器...

+表示...... input+.checkmarkinput应该是相邻的元素......这不属于您的情况......

...请删除.checkmark并将spaninput置于同一级别...

...也使用.checkmark代替opacity:0display:none ...
