PayPal：在多个选项框之间切换？

Question

我一直在阅读有关如何使用 PayPal 表单的信息。我创建了一个表单来使用选项，但我希望能够根据他们选择选项 A 还是选项 B 在两个下拉框之间切换...

（我发现的唯一一个远程接近的问题是——Creating Multiple Select Option Box in Paypal Shopping Cart——我不明白。）

下面是一些示例代码：

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top" data-abide>
    <input type="hidden" name="cmd" value="_xclick">
    <input type="hidden" name="business" value="matt.roberts.33@gmail.com">
    <input type="hidden" name="bn" value="MRobertsDesign_BuyNow_WPS_CA">
    <input type='hidden' name='lc' value='CA'>
    <input type="hidden" name="currency_code" value="CAD">
    <input type="hidden" name="no_shipping" value="0">
    <input type="hidden" name="no_note" value="1">
    <input type="hidden" name="return" value="http://mrobertsdesign.ca/design/payments/completed/">
    <input type="hidden" name="cancel_return" value="http://mrobertsdesign.ca/design/payments/cancelled/">
    <input type="hidden" name="item_number" value="service-plan">

    <input type="text" placeholder="What is your name?" id="pack_name" name="os1" maxlength="100">

    <select id="pack_type" name="item_name">
        <option value="">Choose a plan:</option>
        <option value="Basic">Basic - Starting at $90</option>
        <option value="Advanced">Advanced - Starting at $190</option>
    </select> 

    <!-- Options A (Basic) -->
    <select id="pack_time" name="os0">
        <option value="">Choose your hours:</option>
        <option value="2hrs">2 Hours - $90.00</option>
        <option value="3hrs">3 Hours - $180.00</option>
        <option value="4hrs">4 Hours - $228.00</option>
    </select> 
    <input type="hidden" name="option_select0" value="2hrs">
       <input type="hidden" name="option_amount0" value="90.00">
    <input type="hidden" name="option_select1" value="3hrs">
       <input type="hidden" name="option_amount1" value="180.00">
    <input type="hidden" name="option_select2" value="4hrs">
       <input type="hidden" name="option_amount2" value="228.00">

    <!-- Options B (Advanced) -->
    <select id="pack_time" name="os0">
        <option value="">Choose your hours:</option>
        <option value="2hrs">2 Hours - $190.00</option>
        <option value="3hrs">3 Hours - $240.00</option>
        <option value="4hrs">4 Hours - $328.00</option>
    </select> 
    <input type="hidden" name="option_select0" value="2hrs">
       <input type="hidden" name="option_amount0" value="190.00">
    <input type="hidden" name="option_select1" value="3hrs">
       <input type="hidden" name="option_amount1" value="240.00">
    <input type="hidden" name="option_select2" value="4hrs">
       <input type="hidden" name="option_amount2" value="328.00">

    <input type="hidden" name="on1" value="Client">
    <input type="hidden" name="on0" value="Hours">
    <input type="submit" name="submit" class="button radius payments-buy" value="Buy Now">
</form>

这个想法是当有人选择基本或高级时：

    <select id="pack_type" name="item_name">
        <option value="">Choose a plan:</option>
        <option value="Basic">Basic - Starting at $90</option>
        <option value="Advanced">Advanced - Starting at $190</option>
    </select> 

它将下拉选项分别更改为 A 或 B。

现在我不知道该怎么做，有人有什么想法吗？我不确定您是否理解我在做什么，但如果您需要更多说明，请询问我，我不确定我还能说什么。

我更了解 PHP，所以我明白了……当有人单击该下拉框并选择基本或高级时，它需要触发一个 jQuery 脚本，该脚本将首先检查单击的内容然后循环遍历数组中的值并填充表单。就是不知道怎么弄，有人想试试吗？

为了举例，我非常想获得这个 psuedo-php 代码的 JS/jQuery 版本：

<select id="pack_type" name="item_name">
    <option value="">Choose a plan:</option>
    <option value="Basic">Basic - Starting at $90</option>
    <option value="Advanced">Advanced - Starting at $190</option>
</select> 

<?php
    // I know this doesn't work but for the sake of example
    if (select.pack_type option.basic.selected) {
        var $pack_type = 'basic';
    } elseif (select.pack_type option.advanced.selected) {
        var $pack_type = 'advanced';
    } else {
        var $pack_type = NULL;
    }

    // Basic
    $plan['basic'][] = array(
        'hours' => '2 Hours', 
        'price' => '90.00',
    );
    $plan['basic'][] = array(
        'hours' => '3 Hours', 
        'price' => '120.00',
    );
    $plan['basic'][] = array(
        'hours' => '4 Hours', 
        'price' => '250.00',
    );

    // Advanced
    $plan['advanced'][] = array(
        'hours' => '2 Hours', 
        'price' => '190.00',
    );
    $plan['advanced'][] = array(
        'hours' => '3 Hours', 
        'price' => '220.00',
    );
    $plan['advanced'][] = array(
        'hours' => '4 Hours', 
        'price' => '350.00',
    );

    // Other variables
    $i = 0;

    if ($pack_type == 'basic') {
        // Echo basic
        echo '<select id="pack_time" name="os1"><option value="">Choose your hours:</option>';
            foreach ($plan['basic'] as $prices) {
                echo '<option value="' . $prices['hours'] . '">' . $prices['hours'] . ' - $' . $prices['price'] . '</option>';
            }
        echo '</select>';
        foreach ($plan['basic'] as $prices) {
            echo '<input type="hidden" name="option_select' . $i++ . '" value="' . $prices['hours'] . '"><input type="hidden" name="option_amount' . $i++ . '" value="' . $prices['price'] . '">';
        }
    } elseif ($pack_type == 'advanced') {
        // Echo advanced
        echo '<select id="pack_time" name="os1"><option value="">Choose your hours:</option>';
            foreach ($plan['advanced'] as $prices) {
                echo '<option value="' . $prices['hours'] . '">' . $prices['hours'] . ' - $' . $prices['price'] . '</option>';
            }
        echo '</select>';
        foreach ($plan['advanced'] as $prices) {
            echo '<input type="hidden" name="option_select' . $i++ . '" value="' . $prices['hours'] . '"><input type="hidden" name="option_amount' . $i++ . '" value="' . $prices['price'] . '">';
        }
    } else {
        // Echo nothing
        echo '<select id="pack_time" name="os1"><option value="">Choose your hours:</option></select>';
    }
?>

Answer 1

Paypal 让您可以选择不同价格的产品下拉菜单。

1. 登录贝宝。
2. 转到个人资料选择“我的销售工具”
3. 点击“管理我的付款按钮”旁边的更新
4. 创建一个新按钮
5. 勾选“添加带有价格/选项的下拉菜单”复选框
6. 您将看到如下图所示的屏幕。

添加：这是一个 jsfiddle，它可能会帮助您实现目标。一个下拉菜单，将在选择时显示和隐藏单独的按钮。

jQuery

    $('select.div-toggler').change(function(){
    var target = $(this).data('target');
    $(target).children().addClass('hide');
    var show = $("option:selected", this).data('show');
    $(show).removeClass('hide');
});
