Hi,
emailid is declared in FB.api, in this case emailid isn't visible for $.ajax({....})
Declare emailid before FB.api and just set value for this variable in FB.api

var emailid = "";
 FB.api('/me', function(userInfo) {
    console.log(userInfo.email);
    emailid = userInfo.email;
    console.log(emailid);
})
$.ajax({
    url: 'index.php?r=tryon/saveemailid',
    type:'post',
    data:{'saveemail':emailid},
    success : function(data){
        alert("success!");
    }
});

Just to add, research 'scope of variables' for more info.
