php - 过多的 DOM 元素货币符号

Question

当我运行 pagespeed insight 时，这个 <span class="woocommerce-Price-currencySymbol">导致 Dom 元素过多。我尝试了以下方法但无济于事。许多人遇到过这些问题，但没有人有解决方案。

---

add_filter('woocommerce_currency_symbol', 'change_existing_currency_symbol', 10, 2);

function change_existing_currency_symbol( $currency_symbol, $currency ) {
     switch( $currency ) {
          case 'AUD': $currency_symbol = 'AUD'; break;
     }
     return $currency_symbol;
}


include_once __DIR__ . '/theme-includes/theme-functions.php';

还有这个

add_filter( 'formatted_woocommerce_price', 'span_custom_prc', 10, 5 );

function span_custom_prc( $number_format, $price, $decimals, $decimal_separator, $thousand_separator)
{
    return "<span class='woocommerce-Price-amount amount'>".$number_format."&nbsp;</span>";
}

在您的事件主题 functions.php 中使用以下代码片段。

使用 WooCommerce 6 测试正常

add_filter('wc_price', 'custom_wc_price', 10, 5);

/**
 * Filters the string of price markup.
 *
 * @param string       $return            Price HTML markup.
 * @param string       $price             Formatted price.
 * @param array        $args              Pass on the args.
 * @param float        $unformatted_price Price as float to allow plugins custom formatting. Since 3.2.0.
 * @param float|string $original_price    Original price as float, or empty string. Since 5.0.0.

function custom_wc_price($return, $price, $args, $unformatted_price, $original_price) {
    $args = apply_filters(
            'wc_price_args',
            wp_parse_args(
                    $args,
                    array(
                        'ex_tax_label' => false,
                        'currency' => '',
                        'decimal_separator' => wc_get_price_decimal_separator(),
                        'thousand_separator' => wc_get_price_thousand_separator(),
                        'decimals' => wc_get_price_decimals(),

                    )
            )
    );

    $original_price = $price;

    // Convert to float to avoid issues on PHP 8.
    $price = (float) $price;

    if (apply_filters('woocommerce_price_trim_zeros', false) && $args['decimals'] > 0) {
