我正在尝试连接到Braintree支付系统，并使用以下代码获取客户端令牌ID:
<script src="https://js.braintreegateway.com/js/braintree-2.29.0.min.js"></script>
<script>
clientToken = <?php echo(Braintree_ClientToken::generate()); ?>;
alert(clientToken);
braintree.setup(clientToken, "dropin", {
container: "payment-form"
});
</script>
但是代码无法获取客户端令牌。请帮我解决这个问题
这将帮助您获得客户端令牌:
<script src="https://js.braintreegateway.com/v2/braintree.js"></script>
<?php
$clientToken = Braintree_ClientToken::generate(); // generate token
?>
<script>
clientToken = "<?php echo $clientToken;?>";
alert(clientToken);
braintree.setup(clientToken, "dropin", {
container: "payment-form"
});
</script>
你需要在javascript中为clientToken使用引号
