谷歌登录不提供回调

Question

我实现了一个包含简单谷歌登录按钮的简单页面，如下所示：

 <meta name="google-signin-client_id" content="xyz.apps.googleusercontent.com">
 <script src="https://apis.google.com/js/platform.js" async defer></script>
 <script>
     function onSignInFailure() {
         alert('no work!');
     }

     function onSignIn(googleUser) {
         alert('it work!');
     }
 </script>

 <div class="g-signin2" data-onsuccess="onSignIn" data-onfailure="onSignInFailure" data-theme="dark"></div>

但是当我点击按钮时，我选择了我的谷歌帐户，但没有任何事情发生...... 没有触发“警报”

Answer 1

onSignInFailure中存在语法错误，应该是：

 function onSignInFailure() {
     alert("doesn't work!"); 
 }
