为什么jQuery将单选按钮的值返回为"ON"？怎么改正呢？

Question

我不是绝对的新手，但不知怎么从一个小时开始我就被它抓住了。你能帮我找出我在哪里出错吗？我试图返回“选中/选择”无线电选项的值，并且它每次都返回"on“。

我的(引导) HTML代码：

<div class="form-row mb-4 p-2 text-center font-weight-bold rounded-top shadow-sm-dark no-shadow-hover bl__home_apr-choice">
    <div class="col-4 offset-2 col-md-3 offset-md-0 mb-md-0 mb-1">
      <div class="custom-control custom-radio custom-control-inline">
        <input type="radio" id="searchByProject" name="searchBy" class="custom-control-input" checked="checked">
        <label class="custom-control-label" for="searchByProject" value="Project" pointer>by Project</label>
      </div>
    </div>
    <div class="col-4 col-md-3 offset-md-0 mb-md-0 mb-1">
      <div class="custom-control custom-radio custom-control-inline">
        <input type="radio" id="searchByInvoiceID" name="searchBy" class="custom-control-input">
        <label class="custom-control-label" for="searchByInvoiceID" value="Invoice" pointer>by Invoice</label>
      </div>
    </div>
    <div class="col-4 offset-2 col-md-3 offset-md-0 mb-md-0">
      <div class="custom-control custom-radio custom-control-inline">
        <input type="radio" id="searchByStartDate" name="searchBy" class="custom-control-input">
        <label class="custom-control-label" for="searchByStartDate" value="Started" pointer>by Start Date</label>
      </div>
    </div>
    <div class="col-4 col-md-3 offset-md-0 mb-md-0">
      <div class="custom-control custom-radio custom-control-inline">
        <input type="radio" id="searchByEndDate" name="searchBy" class="custom-control-input">
        <label class="custom-control-label" for="searchByEndDate" value="Ended" pointer>by End Date</label>
      </div>
    </div>
  </div>

我就是这样使用jQuery的：

console.log($('input[name=searchBy]:checked').val()); 

任何帮助都将不胜感激。提前谢谢。

您应该在value标记中设置input，在label中进行设置。

你的收音机应该是这样的：

<input type="radio" id="searchByEndDate" name="searchBy" value="Ended" checked>
