嗨,我有 facebook 登录代码,我想在后面的代码上使用 javascript 变量值。我可以通过将它们保存在隐藏字段中来使用,但没有按钮单击,因此页面不是回发。
这是我的代码:
<script>
// Load the SDK Asynchronously
(function (d) {
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) { return; }
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
} (document));
// Init the SDK upon load
window.fbAsyncInit = function () {
FB.init({
appId: '550050651719081', // App ID
channelUrl: '//' + window.location.hostname + '/channel', // Path to your Channel File
status: true, // check login status
cookie: true, // enable cookies to allow the server to access the session
xfbml: true // parse XFBML
});
// listen for and handle auth.statusChange events
FB.Event.subscribe('auth.statusChange', function (response) {
if (response.authResponse) {
// user has auth'd your app and is logged into Facebook
var uid = "http://graph.facebook.com/" + response.authResponse.userID + "/picture";
FB.api('/me', function (me) {
**document.getElementById('auth-displayname').innerHTML = me.name;
document.getElementById('Email').innerHTML = me.email;
document.getElementById('profileImg').src = uid;**
})
}
});
}
</script>
<h1>
Facebook Login Authentication Example</h1>
<div id="auth-status">
<div id="auth-loggedout">
<div class="fb-login-button" autologoutlink="true" scope="email,user_checkins">Login with Facebook</div>
</div>
<div id="auth-loggedin" style="display: none">
Name: <b><span id="auth-displayname"></span></b>(<a href="#" id="auth-logoutlink">logout</a>)<br />
Email: <b><span id="Email"></span></b><br />
Profile Image: <img id="profileImg" />
</div>
</div>
代码工作正常,但我也想在后面的代码上获取名称、电子邮件和 uid。
