我正在尝试在我的网站上实施谷歌+登录按钮！使用HTML，我不知道为什么按钮本身不起作用。我遵循这些指示： https://developers.google.com/+/web/signin/add-button
这是我到目前为止（我最初找到登录和注销按钮的代码，但决定只使用google + API）
我将这段代码放在哪里？
function signinCallback(authResult) {
if (authResult['status']['signed_in']) {
// Update the app to reflect a signed in user
// Hide the sign-in button now that the user is authorized, for example:
document.getElementById('signinButton').setAttribute('style', 'display: none');
} else {
// Update the app to reflect a signed out user
// Possible error values:
// "user_signed_out" - User is signed-out
// "access_denied" - User denied access to your app
// "immediate_failed" - Could not automatically log in the user
console.log('Sign-in state: ' + authResult['error']);
}
}
我错过了一个onclicklistener或者其他什么？谢谢!!!

我在我的localhost中工作了。 请确保您已按照该链接中的正确步骤。 特别是第一步。
完成第一步后，您必须注意两个重要细节：
现在，如果您运行特定的客户ID生产网址，这段代码可以正常工作（请注意在下面的代码中添加正确的客户ID）

我看到的控制台中的错误是：
回调函数名为＆＃34; signinCallback＆＃34;找不到
您没有使用此处的功能：数据回调=＆＃34; signinCallback＆＃34; 在你的文档中，它就在那里：
function signinCallback(authResult) {
if (authResult['status']['signed_in']) {
// Update the app to reflect a signed in user
// Hide the sign-in button now that the user is authorized, for example:
document.getElementById('signinButton').setAttribute('style', 'display: none');
} else {
// Update the app to reflect a signed out user
// Possible error values:
// "user_signed_out" - User is signed-out
// "access_denied" - User denied access to your app
// "immediate_failed" - Could not automatically log in the user
console.log('Sign-in state: ' + authResult['error']);
}
}
