我正在尝试在http://s195004125.websitehome.co.uk/jobs/由于某些原因，当ios进行更改时，扇区选择框不会更新下面的列表，但当您选择其他位置时，它会更改，我已修改了扇区过滤器以包括以下部分：

<select id="sector" name="search_categories" value="<?php echo esc_attr( $categories ); ?>">>
    <option value="">-- Please Select Sector --</option>
    <option value="Building, Maintenance &amp; Construction">Building, Maintenance &amp; Construction</option>
    <option value="Care &amp; Support">Care &amp; Support</option>
    <option value="Housing">Housing</option>
    <option value="Public Sector &amp; Not for Profit">Public Sector &amp; Not for Profit</option>
    <option selected="selected" value="<?php echo $pull_sector; ?>"><?php echo $pull_sector; ?></option>
</select>

if ( $search_categories ) {
        $showing_categories = array();

        foreach ( $search_categories as $category ) {
            $category_object = get_term_by( is_numeric( $category ) ? \'id\' : \'slug\', $category, \'job_listing_category\' );

            if ( ! is_wp_error( $category_object ) ) {
                $showing_categories[] = $category_object->name;
            }
        }

        $result[\'showing\'][] = implode( \', \', $showing_categories );
    }
