推荐答案
尝试一下
更改
<div class="fb-login-button" onlogin="javascript:CallAfterLogin();" size="medium" scope="<?php echo $fbPermissions; ?>">Connect With Facebook</div>
到
<div class="fb-login-button" onlogin="return CallAfterLogin();" size="medium" scope="<?php echo $fbPermissions; ?>">Connect With Facebook</div>
function CallAfterLogin(){
//alert("2");
FB.login(function(response) {
if (response.status === "connected")
{
LodingAnimate(); //Animate login
FB.api('/me', function(data) {
if(data.email == null)
{
//Facbeook user email is empty, you can check something like this.
alert("You must allow us to access your email id!");
ResetAnimate();
}else{
AjaxResponse();
}
});
}
return true;
});
}
