Javascript 单击按钮时弹出的MailChimp错误

我试图将mailchimp中的弹出式表单添加到我的网站，但我不断收到此错误，尽管我从他们的网站复制粘贴了它

Uncaught TypeError: window.dojoRequire is not a function
    at showMailingPopUp (index.html:39)
    at HTMLInputElement.onclick (index.html:116)

这是我的密码：

<script type="text/javascript" src="http://downloads.mailchimp.com/js/signup-forms/popup/unique-methods/embed.js" data-dojo-config="usePlainJson: true, isDebug: false"></script>
<script>
function showMailingPopUp() {
document.cookie = "MCEvilPopupClosed=; expires=Thu, 01 Jan 1970 00:00:00 UTC";
window.dojoRequire(["mojo/signup-forms/Loader"], function(L) { L.start({"baseUrl":"mc.us4.list-manage.com","uuid":"fd5cf79a3e9cee3f451200e01","lid":"ce87ac273d","uniqueMethods":true}) })
};

    </script>
<input type="button" class="subscribe-button" id="open-popup" onClick="showMailingPopUp()" value="Subscribe">

函数showMailingPopUp（）{
document.cookie=“mcevipopupclosed=；expires=Thu，1970年1月1日00:00:00 UTC”；
window.dojoRequire（[“mojo/signup forms/Loader”]，函数（L）{L.start（{“baseUrl”：“mc.us4.list manage.com”，“uuid”：“fd5cf79a3e9cee3f451200e01”，“lid”：“ce87ac273d”，“uniqueMethods”：true}）
};
