我用这个选择显示柜台
<section class="shipping-calculator-form-shortcode" >
<p class="form-row form-row-wide" id="calc_shipping_country_field">
<label >Shipping options to</label>
<select onchange="myFunctionShipping(this)" name="calc_shipping_country" id="calc_shipping_country" class="ss-woo-shipping-calculator" rel="ss-woo-shipping-calculator">
<option value="1"><?php _e( 'Select a country…', 'woocommerce' ); ?></option>
<?php
foreach ( WC()->countries->get_shipping_countries() as $key => $value )
echo '<option value="' . esc_attr( $key ) . '"' . selected( WC()->customer->get_shipping_country(), esc_attr( $key ), false ) . '>' . esc_html( $value ) . '</option>';
?>
</select>
</p>
<span id="ss-woo-shipping-calculator-loading" style="display:none"><img src='<?php echo plugins_url( '/default.gif', __FILE__ ) ?>' /></span>
</p>
<?php wp_nonce_field( 'woocommerce-cart' ); ?>
<div id="ss-woo-shipping-result">
</div>
</section>
然后通过javascript代码检索它的运输选项
<script type="text/javascript">
var $s = jQuery.noConflict();
function myFunctionShipping(item) {
$s(document).ready(function($) {
$("select").change(function(){
var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>";
var country = item.value;
$("#ss-woo-shipping-calculator-loading").show();
var data = {'action': 'ss_woo_shipping_calculator','country': country};
$.post("<?php echo get_home_url(); ?>", data, function(response) {
$("#ss-woo-shipping-calculator-loading").hide();
response = JSON.parse(response);
if(response.result == 1){
$("#ss-woo-shipping-result").html(response.message);
}else{
$("#ss-woo-shipping-result").html("");
}
return false;
});
return false;});
});
}
问题是: - 如果任何其他选择控件也发生更改,它也会触发它仅在更改选择两次后触发(页面加载后)
