Javascript 如何向需要客户信息的WooCommerce感谢页面添加自定义JS代码

如何将此第三方脚本添加到需要填充某些客户数据的Woocommerce感谢页面：

<script type="text/javascript">
lr(function(){
    var customerEmail = '{customer_email}';
    if (customerEmail.includes("@")) {
        REFERSION.box.show({
            loc : 'https://www.refersion.com/channels/post_purchase/v2',
            code : '2bf89afa29',
            customer_first_name : encodeURIComponent('{customer_first_name}'),
            customer_last_name : encodeURIComponent('{customer_last_name}'),
            customer_email : encodeURIComponent('{customer_email}')
        });
    }
});
function lr(e){var t=document.createElement("script");t.type="text/javascript";if(t.readyState){t.onreadystatechange=function(){if(t.readyState=="loaded"||t.readyState=="complete"){t.onreadystatechange=null;e()}}}else{t.onload=function(){e()}}t.src="https://www.refersion.com/channels/post_purchase/v2/js";document.body.appendChild(t)}
</script>

lr（函数（）{
var customerEmail='{customer_email}'；
if（CustomerMail.includes（“@”））{
reference.box.show({
loc:'https://www.refersion.com/channels/post_purchase/v2',
代码：“2bf89afa29”，
customer\u first\u name:encodeURIComponent（“{customer\u first\u name}”），
customer_last_name:encodeURIComponent（“{customer_last_name}”），
客户电子邮件：encodeURIComponent（“{customer\u email}”）
});
}
});
函数lr（e）{var t=document.createElement（“脚本”）；t.type=“text/javascript”；if（t.readyState）{t.onreadystatechange=function（）{if（t.readyState==“loaded”| t.readyState==“complete”）{t.onreadystatechange=null；e（）}}}else{t.onload=function（）{e（）}t.src='https://www.refersion.com/channels/post_purchase/v2/js“document.body.appendChild（t）}”

添加动作（“感谢之前的woocommerce”，“感谢之前的woocommerce”，10，1）；
感谢之前的功能（$order\u id）{
$order=wc\u get\u order（$order\u id）；
回声“
lr（函数（）{
var customerEmail='{$order->get_billing_email（）}'；
if（customerEmail.includes（'@'））{
reference.box.show({
loc:'https://www.refersion.com/channels/post_purchase/v2',
代码：“2bf89afa29”，
customer_first_name:encodeURIComponent（“{$order->get_billing_first_name（）”），
customer_last_name:encodeURIComponent（“{$order->get_billing_last_name（）”），
客户电子邮件：encodeURIComponent（“{$order->get\u billing\u email（）}”）
});
}
});
函数lr（e）{var t=document.createElement（'script'）；t.type='text/javascript'；if（t.readyState）{t.onreadystatechange=function（）{if（t.readyState=='loaded'.| t.readyState=='complete'）{t.onreadystatechange=null；e（）}}否则{t.onload=function（）{e（）}t.src='https://www.refersion.com/channels/post_purchase/v2/js'；document.body.appendChild（t）}
";
}

正是你要找的

add_action('woocommerce_before_thankyou', 'woocommerce_before_thankyou', 10 , 1);

function woocommerce_before_thankyou( $order_id ) {

            $order = wc_get_order( $order_id );
            echo "
<script type='text/javascript'>
lr(function(){
    var customerEmail = '{$order->get_billing_email()}';
    if (customerEmail.includes('@')) {
        REFERSION.box.show({
            loc : 'https://www.refersion.com/channels/post_purchase/v2',
            code : '2bf89afa29',
            customer_first_name : encodeURIComponent('{$order->get_billing_first_name()}'),
            customer_last_name : encodeURIComponent('{$order->get_billing_last_name()}'),
            customer_email : encodeURIComponent('{$order->get_billing_email()}')
        });
    }
});
function lr(e){var t=document.createElement('script');t.type='text/javascript';if(t.readyState){t.onreadystatechange=function(){if(t.readyState=='loaded'||t.readyState=='complete'){t.onreadystatechange=null;e()}}}else{t.onload=function(){e()}}t.src='https://www.refersion.com/channels/post_purchase/v2/js';document.body.appendChild(t)}
</script>
";
        }
