如果单选按钮检查更改父div（li）背景 - javascript [英] If radio button checked change parent div (li) background - javascript

问题描述

我有单选按钮里面的li元素，
我想改变li（父div）一旦选中单选按钮的背景颜色。我成功地通过CSS设置悬停在李，但它看起来像：checked不工作在父div。
这是我的html + css代码：

I have radio button inside li element, I would like to change the background color of the li (the parent div) once the radio button checked. I succeeded to set hover on the li by CSS, but it seems like the :checked not works on parent div. This is my html + css code:

.job-manager-term-checklist { 
    margin: 1em 0 0;
    padding: 0;
    list-style: none;
    overflow: hidden;
  }

.job-manager-term-checklist li {
    border: 1px solid #ccc;
    overflow: auto;
    padding: 5px;
    margin-left: 5px;
    border-radius: 5px;
    background-color: #ebf1f9;
    width: 20%;
  }

.job-manager-term-checklist li:hover { 
  background-color: #4e83ca;
  color: #fff;
  }

<div class="field required-field">
  <ul class="job-manager-term-checklist job-manager-term-checklist-job_category">
    <li id="job_listing_category-72" class="popular-category"><label class="selectit"><input value="72" type="radio" name="tax_input[job_listing_category][]" id="in-job_listing_category-72">1</label></li>
    <li id="job_listing_category-73"><label class="selectit"><input value="73" type="radio" name="tax_input[job_listing_category][]" id="in-job_listing_category-73">2</label></li>
    <li id="job_listing_category-75"><label class="selectit"><input value="75" type="radio" name="tax_input[job_listing_category][]" id="in-job_listing_category-75">3</label></li>
    <li id="job_listing_category-76"><label class="selectit"><input value="76" type="radio" name="tax_input[job_listing_category][]" id="in-job_listing_category-76">4</label></li>
    <li id="job_listing_category-80"><label class="selectit"><input value="80" type="radio" name="tax_input[job_listing_category][]" id="in-job_listing_category-80">5</label></li>
    <li id="job_listing_category-86"><label class="selectit"><input value="86" type="radio" name="tax_input[job_listing_category][]" id="in-job_listing_category-86">6</label></li>
    <li id="job_listing_category-98"><label class="selectit"><input value="98" type="radio" name="tax_input[job_listing_category][]" id="in-job_listing_category-98">7</label></li>
  </ul>
</div>

推荐答案

这应该可以：

function updateHighlightRadio() {
  var selected = this.parentNode.parentNode.parentNode.getElementsByClassName("selected")[0];
  if (selected) selected.className = selected.className.replace(" selected", "");
  this.parentNode.parentNode.className += " selected";
}

function updateHighlightCheckbox() {
  var selected = this.parentNode.parentNode;
  if (!this.checked)
    selected.className = selected.className.replace(" selected", "");
  else
    this.parentNode.parentNode.className += " selected";
}

window.onload = function () {
  var radios = document.querySelectorAll("input[type=radio]");
  for (var i = 0; i < radios.length; ++i) {
    radios[i].onchange = updateHighlightRadio;
  }

  var checkboxes = document.querySelectorAll("input[type=checkbox]");
  for (var i = 0; i < checkboxes.length; ++i) {
    checkboxes[i].onchange = updateHighlightCheckbox;
  }
}

.job-manager-term-checklist {
  margin: 1em 0 0;
  padding: 0;
  list-style: none;
  overflow: hidden;
}
.job-manager-term-checklist li {
  border: 1px solid #ccc;
  overflow: auto;
  padding: 5px;
  margin-left: 5px;
  border-radius: 5px;
  background-color: #ebf1f9;
  width: 20%;
}
.job-manager-term-checklist li:hover {
  background-color: #4e83ca;
  color: #fff;
}
.job-manager-term-checklist .selected {
  background-color: #a2156b;
  color: #fff;
}
