Google reCAPTCHA data-callback not working
提问by roshambo
I have built a email newsletter signup form which posts into mailchimp from my website. I have Google reCAPTCHA added to the form and have a data-callback to enable the submit button as it is initially disabled. This was working fine in all browsers last night and did tests with success & signed off on it..and went home. I got in this morning and found the subscribe button will not enable / data-callback does not work? Strange..
我已经建立了一个电子邮件通讯注册表格，可以从我的网站发布到 mailchimp。我在表单中添加了 Google reCAPTCHA，并有一个数据回调来启用提交按钮，因为它最初被禁用。昨晚在所有浏览器中都运行良好，并成功进行了测试并签署了它......然后回家了。我今天早上起来，发现订阅按钮无法启用/数据回调不起作用？奇怪的..

Change your script to...
将您的脚本更改为...
<script type="text/javascript">
function recaptcha_callback(){
alert("callback working");
$('.button').prop("disabled", false);
}
</script>
By placing your function inside the document.readyevent, it is not in the global scope and therefore unreachable by the captcha control.
通过将您的函数放在document.ready事件中，它不在全局范围内，因此验证码控件无法访问。
