facebook付款對話框僅顯示信用點數，當我點擊購買信用而不是它應該轉到下一個對話框，它應該問我付款選項，它只是說您的購買成功。不知道我在做什麼嘗試了一切，但它不工作。facebook付款對話框不顯示本地貨幣對話框
這裏是我的javascript函數
function buy_tokens(p){
FB.init({appId: "myappid", status: true, cookie: true});
var obj = {
method: 'pay',
action: 'buy_item',
order_info: {'item_id': 'tokens', 'price':p},
dev_purchase_params: {'oscif': true}
};
//FB.ui(obj, js_callback);
FB.ui(obj, function(paydata) {
// response back
});
}
