登录谷歌不提供回调

Question

我已经实现一个简单的页面包含一个简单的谷歌登录按钮，像这样：

<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，选择我的谷歌帐户，但没有发生...... 没有“警报”触发

Answer 1

你有onSignInFailure语法错误，应该是：在开发者工具控制台

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