谁能告诉我为什么回调不适用于下面给出的类似按钮代码?据我所知,该代码是 JavaScript 中设置的标准。初始化第一个按钮,然后异步加载API,并提供回调函数。
<div id="fb-root"></div>
<script>
window.fbAsyncInit=function(){
FB.init({
appId:'',//App ID
status:false,// check login status
cookie:true,// enable cookies to allow the server to access the session
xfbml:true// parse XFBML
});
// Additional initialization code here
FB.Event.subscribe('edge.create', function(response) {
//alert("user_id1:<?php echo $user_id1; ?>, user_id2:<?php echo $user_id2; ?>");
/*var data={
action:"ap_buttons_give_points",
author_id:<?php echo $author_id; ?>,
post_id:<?php echo $post_id; ?>,
type:"like"
}
jQuery.post("<?php echo $ajax_url; ?>",data,function(resp){
});*/
alert('You just liked the page!');
});
FB.Event.subscribe('edge.remove', function(response) {
/*var data={
action:"ap_buttons_take_points",
author_id:<?php echo $author_id; ?>,
post_id:<?php echo $post_id; ?>,
type:"like"
}
jQuery.post("<?php echo $ajax_url; ?>",data,function(resp){
//alert("fb remove:"+resp);
});*/
alert('You just unliked the page!');
});
};
// 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));
</script>
