javascript - 我如何找到该标签的子项？ (HTML+JS)

Question

如何让JS找到“money”类的 child ？我对其进行了编码，以便在单击时它会找到单选按钮。单击后，它将返回该单选按钮和 id。但我还需要找到“金钱”类。

HTML:

<div class="col-sm-4 col-md-2">
  <input name="STORAGE" type="radio" id="STORAGE2">
  <label class="radio" for="STORAGE2">
    <center>
      <img src="../images/Parts/Western_Digital_Caviar_Blue_320GB.png" class="comp-img"><br><br>
      <p>500GB Western Digital WD5000AAKX 3.5" 7200RPM HDD</p>
      <p class="money">+$55</p> <!--THIS IS THE CLASS I AM TRYING TO GET-->
    </center>
  </label>
</div>

JS:

$(function(){
  var cpu = "";

  //Controling radio buttons
  $('radio').on('click'), function(){
    var clickedID = $(this).attr("id");
    if (clickedID.substring(1,3) == "CPU") {
      if (cpu == "") {
        cpu = clickedID;

      } else {

      }
    }
  }
});

Answer 1

如果标签的 for 属性是 radio ID 的值，那么您可以这样做

var el = $('label[for='+clickedID +']').find('.money');
