如何通过单击文本而不是复选框本身来选中或取消选中复选框？

<label for="checkboxId">文本内容</label>
<input type="checkbox" id="checkboxId">

<span onclick="toggleCheckbox('checkboxId')">文本内容</span>
<input type="checkbox" id="checkboxId">

<script>
function toggleCheckbox(checkboxId) {
  var checkbox = document.getElementById(checkboxId);
  checkbox.checked = !checkbox.checked;
}
</script>

<label class="custom-checkbox">
  <span>文本内容</span>
  <input type="checkbox">
</label>

<style>
.custom-checkbox {
  position: relative;
  padding-left: 25px;
  cursor: pointer;
}

.custom-checkbox input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
}

.custom-checkbox span {
  position: absolute;
  top: 0;
  left: 0;
  height: 20px;
  width: 20px;
  background-color: #eee;
}

.custom-checkbox input:checked + span {
  background-color: #2196F3;
}

.custom-checkbox span:after {
  content: "";
  position: absolute;
  display: none;
}

.custom-checkbox input:checked + span:after {
  display: block;
}

.custom-checkbox span:after {
  left: 7px;
  top: 3px;
  width: 5px;
  height: 10px;
  border: solid white;
  border-width: 0 2px 2px 0;
  transform: rotate(45deg);
}
</style>
