我在将变体下拉列表转换为支持 woocommerce 的网站的单选按钮时遇到问题。我已经尝试找到答案here https://stackoverflow.com/questions/11819604/dropdown-converted-to-radio-buttons-no-longer-triggering-specific-function但我似乎无法使这个解决方案发挥作用。我还尝试编辑variable.php 文件中的代码。
到目前为止，最成功的是第二种方法，编辑variable.php代码并将标签更改为标签。问题是单击单选按钮时不会触发自然的 jQuery 事件。
如果你们中有人知道一种更简单的方法将下拉列表转换为单选按钮，或者简单地触发 jQuery 事件，我们将不胜感激。
我可以得到的相关代码：
<?php $loop = 0; foreach ( $attributes as $name => $options ) : $loop++; ?>
<tr>
<td class="label"><label for="<?php echo sanitize_title($name); ?>"><?php echo $woocommerce->attribute_label($name); ?></label></td>
<td class="value"><select id="<?php echo esc_attr( sanitize_title($name) ); ?>" name="attribute_<?php echo sanitize_title($name); ?>">
<option value=""><?php echo __('Choose an option', 'woocommerce') ?>…</option>
<?php
if ( is_array( $options ) ) {
if ( empty( $_POST ) )
$selected_value = ( isset( $selected_attributes[ sanitize_title( $name ) ] ) ) ? $selected_attributes[ sanitize_title( $name ) ] : '';
else
$selected_value = isset( $_POST[ 'attribute_' . sanitize_title( $name ) ] ) ? $_POST[ 'attribute_' . sanitize_title( $name ) ] : '';
// Get terms if this is a taxonomy - ordered
if ( taxonomy_exists( sanitize_title( $name ) ) ) {
$terms = get_terms( sanitize_title($name), array('menu_order' => 'ASC') );
foreach ( $terms as $term ) {
if ( ! in_array( $term->slug, $options ) ) continue;
echo '<option value="' . $term->slug . '" ' . selected( $selected_value, $term->slug ) . '>' . apply_filters( 'woocommerce_variation_option_name', $term->name ) . '</option>';
}
} else {
foreach ( $options as $option )
echo '<option value="' . $option . '" ' . selected( $selected_value, $option ) . '>' . apply_filters( 'woocommerce_variation_option_name', $option ) . '</option>';
}
}
?>
相关 JavaScript。我将“选择”元素更改为“输入：无线电”，但它仍然不起作用。
