Google ReCAPTCHA callback function not working
提问by Just some guy
I use Google's reCAPTCHA on my website and I'm having problems getting it to call a callback function. After a user has successfully passed the captcha I want to call a function. I use a div with these attributes to render the captcha:
我在我的网站上使用了 Google 的 reCAPTCHA，但在让它调用回调函数时遇到了问题。用户成功通过验证码后，我想调用一个函数。我使用具有这些属性的 div 来呈现验证码：
class='g-recaptcha' data-sitekey='keyhere' data-callback='alert(1);'
However, I can't get the alert(1);to trigger, nothing happens when I fill out the captcha. Everything else about the captcha works fine, I just can't get it to call the function. What could I be doing wrong?
但是，我无法alert(1);触发，当我填写验证码时没有任何反应。关于验证码的其他一切工作正常，我只是无法让它调用该函数。我可能做错了什么？

I haven't used it, so I don't know if this will help, but looking at the few examples online that I can find, it looks like data-callbackshould be a function name, not the script body:
我没有使用过，所以不知道这是否有帮助，但是查看我可以找到的几个在线示例，它看起来data-callback应该是函数名称，而不是脚本主体：
class='g-recaptcha' data-callback='doSomething'
function doSomething() { alert(1); }
