结帐时根据状态代码显示消息

Question

我尝试在选择某些州作为计费州时触发短信。我显示了该消息，但它只会显示一种状态。当我尝试将其他人添加到“var stateCode”中时，我没有运气。这是我到目前为止所拥有的。我应该如何添加其他状态来触发消息显示？

//Sales Tax Warning Script
add_action( 'woocommerce_checkout_before_order_review', 'show_prop_message' );

function show_prop_message() {
echo '<div class="prop65-warning woocommerce-warning" style="display:none;"><p 
style="font-size:9pt; padding:10px 10px; border:1px solid #d1d18e; background- 
color:#ffffb8;"><img src="https://emartmedia.com/images/bw6pt.png" /><strong>

}

// Second Step
// Show or hide warning message based on billing and shipping state
// First trigger is fired on billing state selection in case the "Ship to a 
different address" checkbox is unselected
// Second trigger is fired if the "Ship to a different address" checkbox is ticked
// Initally the "display:none" hides the warning message by default

add_action( 'woocommerce_after_checkout_form', 'show_warning_message' );
function show_warning_message(){  
      ?> 

 <script>
    jQuery(document).ready(function($){

        // Set the shipping state 2 char code (This selection will fire the warning message display)
        // Fires secondary if shipping state is set to California
    var stateCode = 'WI';


        $('select#billing_state').change(function(){

            selectedState = $('select#billing_state').val();

            if( selectedState == stateCode ){
                $('.prop65-warning').show();
            }
            else {
                $('.prop65-warning').hide();
            }
        });

    }); 
    </script>
    <script>

     jQuery(document).ready(function($){ 

        // Set the billing state 2 char code (This selection will fire the warning message display)
        // Fires initially if billing state is California
        var stateCode = 'WI';


        $('select#billing_state').change(function(){

            selectedState = $('select#billing_state').val();

            if( selectedState == stateCode ){
                $('.prop65-warning').show();
            }
            else {
                $('.prop65-warning').hide()

Answer 1

我建议将状态添加到数组中，然后使用

includes()

方法来查看该值是否与其中一个状态匹配。它看起来像这样：

var stateCode = ['WI', 'NY', 'FL', 'CA'];

$('select#billing_state').change(function(){
    selectedState = $('select#billing_state').val();
    if( stateCode.includes(selectedState) ){
        $('.prop65-warning').show();
    }
    else {
        $('.prop65-warning').hide();
    }
});

Answer 2

你让这个代码工作了吗？我尝试在我的functions.php 中使用它，但它导致了一个严重错误。基本上需要相同的功能（根据运输状态显示消息）
