我在使用Facebook社交插件时遇到问题。我的网站中的“赞和评论”框仅在刷新浏览器后出现。有谁知道为什么会这样，我该如何解决？我正在使用Meteor构建我的网站，只有在用户登录后才能访问放置社交插件的页面。非常感谢！ :)
测试网站为www.sgeasyaidtest.meteor.com，社交插件位于计划器页面下。
这是我放置在标记下的FB登录和社交插件的脚本：
<body>
{{#if currentUser}}
<!--FB login-->
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '1027408483945691',
xfbml : true,
version : 'v2.4'
});
};
(function(d, s, id){
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
<div
class="fb-like"
data-share="true"
data-width="450"
data-show-faces="true">
</div>
<script>
// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === 'connected') {
// Logged into your app and Facebook.
testAPI();
} else if (response.status === 'not_authorized') {
// The person is logged into Facebook, but not your app.
document.getElementById('status').innerHTML = 'Please log ' +
'into this app.';
} else {
// The person is not logged into Facebook, so we're not sure if
// they are logged into this app or not.
document.getElementById('status').innerHTML = 'Please log ' +
'into Facebook.';
}
}
// This function is called when someone finishes with the Login
// Button. See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function() {
FB.init({
appId : '692361547558190',
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v2.2' // use version 2.2
});
// Now that we've initialized the JavaScript SDK, we call
// FB.getLoginStatus(). This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide. They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.
//
// These three cases are handled in the callback function.
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
};
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
// Here we run a very simple test of the Graph API after login is
// successful. See statusChangeCallback() for when this call is made.
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Successful login for: ' + response.name);
document.getElementById('status').innerHTML =
'Thanks for logging in, ' + response.name + '!';
});
}
</script>
</div>
<!--FB 'like' -->
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.4&appId=1027408483945691";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
<!-- FB comment plugins -->
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.4&appId=1027408483945691";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
这是我放置在页面中希望社交插件出现的代码。
<!-- 'like & share' plugin -->
<div class="fb-like" data-href="http://www.facebook.com/sgeasyaid" data-layout="button" data-action="like" data-show-faces="true" data-share="true"></div>
<!-- "comment" plugins -->
<div class="fb-comments" data-href="https://www.facebook.com/sgeasyaid" data-width="500" data-numposts="2"></div>
最佳答案
不要在HTML正文中包含<script>标记。 Meteor使用复杂的模板系统，由于Meteor的反应性，该系统可能会修改DOM。
因此，您应该将外部脚本放入模板事件中，例如Template.myTemplate.onRendered函数。但是，我建议您使用biasport:facebook-sdk，它打包了Facebook SDK。
您可以在Meteor应用程序中包括社交插件，如下所示：
运行meteor add biasport:facebook-sdk安装提到的软件包。
初始化SDK：
if(Meteor.isClient) {
window.fbAsyncInit = function() {
FB.init({
appId: 'your-app-id', // Specify your app id here
status: true,
xfbml: true,
version: 'v2.1' // Specify your version here
});
};
}
在您的Meteor模板中包括所需的社交插件，例如：
<template name="facebookLikeButton">
<div class="fb-like" data-href="http://www.facebook.com/sgeasyaid" data-layout="standard" data-action="like"
data-show-faces="true" data-share="true"></div>
</template>
您也可以将built-in template helpers用于社交插件。
