默認的單選按鈕被選中，但下拉不能正確顯示

Question

我有一個網站，上面有一張信用卡付款表格，我用在其他非常相似的網站上。我遇到的一個問題是，當頁面加載時，信用卡付款選項會自動選中，通常會顯示信用卡的下拉列表。但是，在此站點上，直到在顯示爲已選中的單選按鈕上發生第二次單擊之前，列表纔會顯示。如果有人有任何可能導致這種情況的信息，我會非常感激！如果您將任何內容添加到購物車並查看購物車頁面，則可以在www.seed-city.com（NSFW）處看到該問題。感謝您的時間。

你可以看到這裏的問題：

http://www.seed-city.com/index.php?option=com_virtuemart &頁= shop.cart & add_id [] = 270 & qadd_270 = 10

我的代碼是：

<div class="yagendoo_vm_checkout_credit_input"> 
     <table> 
      <tr> 
       <td nowrap width="10%" align="left"><?php echo $VM_LANG->_('VM_CREDIT_CARD_TYPE'); ?>:</td> 
       <td>   
        <script language="Javascript" type="text/javascript"><!-- 
         writeDynaList('class="inputbox" name="creditcard_code" size="1"', 
         orders, originalPos, originalPos, originalOrder); 
         //--> 
        </script> 
        <?php 
         $db_cc->reset(); 
         $payment_class = $db_cc->f("payment_class"); 
         $require_cvv_code = "YES"; 
         if(file_exists(CLASSPATH."payment/$payment_class.php") && file_exists(CLASSPATH."payment/$payment_class.cfg.php")): 
          require_once(CLASSPATH."payment/$payment_class.php"); 
          require_once(CLASSPATH."payment/$payment_class.cfg.php"); 
          $_PAYMENT = new $payment_class(); 
          if(defined($_PAYMENT->payment_code.'_CHECK_CARD_CODE')):?> 
           <?php $require_cvv_code = strtoupper(constant($_PAYMENT->payment_code.'_CHECK_CARD_CODE'));?> 
          <?php endif; 
        endif;?> 
       </td> 
      </tr> 
      <tr valign="top"> 
       <td nowrap width="10%" align="left"> 
        <label for="order_payment_name"> 
         <?php echo $VM_LANG->_('PHPSHOP_CHECKOUT_CONF_PAYINFO_NAMECARD') ?>: 
        </label> 
       </td> 
       <td> 
        <input type="text" class="inputbox" id="order_payment_name" name="order_payment_name" value="<?php if(!empty($_SESSION['ccdata']['order_payment_name'])) echo $_SESSION['ccdata']['order_payment_name'] ?>" autocomplete="off" /> 
       </td> 
      </tr> 
      <tr valign="top"> 
       <td nowrap width="10%" align="left"> 
        <label for="order_payment_number"><?php echo $VM_LANG->_('PHPSHOP_CHECKOUT_CONF_PAYINFO_CCNUM') ?>:</label> 
       </td> 
       <td> 
        <input type="text" class="inputbox" id="order_payment_number" name="order_payment_number" value="<?php if(!empty($_SESSION['ccdata']['order_payment_number'])) echo $_SESSION['ccdata']['order_payment_number'] ?>" autocomplete="off" /> 

更多代碼：

 foreach($cards as $code => $name) { 

      $script .= "orders[".$i++."] = new Array('".addslashes($db_cc->f("payment_method_name"))."','$code','$name');\n"; 

     } 



     } 

     $script .= "function changeCreditCardList() { \n"; 

     $script .= "var selected_payment = null; 

    for (var i=0; i<document.adminForm.payment_method_id.length; i++) 

    if (document.adminForm.payment_method_id[i].checked) 

     selected_payment = document.adminForm.payment_method_id[i].id;\n"; 

     $script .="changeDynaList('creditcard_code',orders,selected_payment, originalPos, originalOrder);\n"; 

     $script .="}\n"; 

     $script .="//-->\n"; 

     $script .="</script>\n"; 

     $script .= '<noscript>'.ps_html::selectList('creditcard_code', key($cards), $cards).'</noscript>'; 

     return $script; 

    } 

} 

Answer 1

你有一個選擇，沒有項目：

<select class="inputbox" name="creditcard_code" size="1"> </select> 

的項目是通過腳本加載它

/*<![CDATA[*/var originalOrder = '1'; 
var originalPos = 'payment_method_id_3'; 
var orders = new Array(); // array in the format [key,value,text] 
orders[0] = new Array('payment_method_id_3','VISA','Visa'); 
orders[1] = new Array('payment_method_id_3','MC','MasterCard'); 
orders[2] = new Array('payment_method_id_3','jcb','JCB'); 
orders[3] = new Array('payment_method_id_3','australian_bc','Australian Bankcard'); 
orders[4] = new Array('payment_method_id_3','SWITCH','Maestro'); 
function changeCreditCardList() { 
var selected_payment = null; 
     for (var i=0; i<document.adminForm.payment_method_id.length; i++) 
     if (document.adminForm.payment_method_id[i].checked) 
      selected_payment = document.adminForm.payment_method_id[i].id; 
op_changeDynaList('creditcard_code',orders,selected_payment, originalPos, originalOrder); 
}/*]]>*/ 

上面我假設op_changeDynaList功能應該與陣列加載select。看起來changeCreditCardList可能是onchange處理程序。

再次，這是應該在問題中的東西。但是，我沒有看到第一次實際加載列表的位置。您可能需要在頁面加載後手動調用其中一個函數（如changeCreditCardList），而不是等待第一個事件被觸發。
