問題描述

我使用下面的代碼返回上一頁，但它不起作用.即使我在頁面上單擊確定"，警報框仍會彈出.實際上有 3 頁包含此 Windows 頁面代碼.第一頁是用戶需要填寫的表格名稱redeem_newcust.asp，操作應該是將所有數據保存到名為redeem_newcustDB.asp的數據庫中.在redeem_newcustDB.asp 頁面中有一個代碼可以選擇兌換類型的選項，然后此頁面將指向redeem_newprocess.asp 頁面的操作，其中包含如下代碼.表示當用戶點擊不等于生日禮包 - PDV RM50"的兌換類型時，它應該返回到上一頁，即頁面redeem_newcustDB.asp.有可能回到上一頁..?b 是否需要帶來所有的價值?請幫忙，謝謝

推薦答案

使用:window.history.back() 代替 .go();

或使用:

window.alert("Please choose Type of Redemption");
setTimeout(function(){
  window.history.go(-1);
},500);
