javascript - Opcheckout 未检测到复选框

Question

我正在构建一个电子商务软件并​​卡在付款结帐页面上。我决定使用 OP Checkout，称为 Magento Checkout，并包含所有必需的 JS 文件。问题是当我单击“继续”按钮时，它没有检测到勾选了哪个复选框。当我调试到警报消息时，我发现这行代码需要捕获用户交互。

if ($('login:guest') && $('login:guest').checked) {

HTML 代码:

<div class="col-md-6">
  <h3>Checkout as a Guest or Register</h3>
  <div class="space10"></div>
  <p>Register with us for future convenience:</p>
  <div class="cbox">
    <input name="checkout_method" id="login:guest" value="guest" class="radio" type="radio"><span for="login:guest">Checkout as Guest</span><br>
    <div class="space10"></div>
    <input name="checkout_method" id="login:register" value="register" class="radio" type="radio"><span for="login:register">Register</span>
  </div>
  <div class="space20"></div>
  <h4>Register and save time!</h4>
  <div class="space10"></div>
  <p>Register with us for future convenience:</p>
  <ul class="ul">
    <li><i class="fa fa-check"></i> Fast and easy check out</li>
    <li><i class="fa fa-check"></i> Easy access to your order history and status</li>
  </ul>
  <div class="space10"></div>

  <button id="onepage-guest-register-button" type="button" class="button btn-black" onclick="checkout.setMethod();"><span><span>Continue</span></span></button>
</div>

上面的代码没有捕捉到结果。

Answer 1

对 id 选择器使用 # 并转义 : from id (Read Selector docs) 就像，

if ($('#login\\:guest').is(':checked')) { //escape : by using \\

另一种使用方式是，

$('[id="login:guest"]').is(':checked');

片段，

$(function() {
  $('#btnCheck').on('click', function() {
    alert($('#login\\:guest').is(':checked') + ',' + $('[id="login:register"]').is(':checked'));
  });
});

<div class="cbox">
  <input name="checkout_method" id="login:guest" value="guest" class="radio" type="radio"><span for="login:guest">Checkout as Guest</span><br>
  <div class="space10"></div>
  <input name="checkout_method" id="login:register" value="register" class="radio" type="radio"><span for="login:register">Register</span>
  <button id="btnCheck">Check</button>
</div>
