正在緩存AJAX響應

Question

我再次發佈與上一個類似的問題，但這次我的問題不同。作爲所述代碼如下：

$.ajax({ 
      type:"POST", 
      url: 'sample.php', 
      data:"data="+data, 
      success: function(server_response) { 
      $('.functions').ajaxComplete(function(event, request){ 

       if(server_response == 0) 
       { 
          var message = 'An email with instructions to reset password has been sent to your email address. Please check it.'; 
       } 
       else if(server_response == 1) 
       { 
          var message = 'Email address was not found in our database. Please enter a valid email address'; 
       } 
       else 
       { 
          var message = 'Some problem occured while sending you an email. Please try again.';          
       } 
    alert(message); 

    }); 

的問題是每當我傳遞一個AJAX請求接收到的服務器響應是正確的，但如果上面的代碼而不頁多次執行刷新多個對話框在堆疊收到訂購。就像如果我的第一個響應是0，那麼會收到消息「一封帶有重置指令的電子郵件」。但是，如果我再次發送請求而不刷新頁面，並且這是我的（如果我的頁面響應爲1），則會生成2個對話框，並顯示消息「在我們的數據庫中找不到電子郵件地址」。在上面和下面的前一個。這樣的堆棧繼續生成，直到我刷新頁面。我嘗試了所有的東西，例如將緩存設置爲false和所有東西，但都是徒勞的。請幫忙。

Answer 1

POST請求永遠不會被緩存。

嘗試$。員額代替

$.post('sample.php', {"data="+data}, function(server_response) { 
     if(server_response == 0) 
     { 
       var message = 'An email with instructions to reset password has been sent to your email address. Please check it.'; 
     } 
     else if(server_response == 1) 
     { 
      var message = 'Email address was not found in our database. Please enter a valid email address'; 
     } 
     else 
     { 
      var message = 'Some problem occured while sending you an email. Please try again.';          
     } 
});

在jQuery的AJAX選項替代通cache: false類似如下：

$.ajax({ 
      type:"POST", 
      cache: false, 
      url: 'sample.php', 
      data:"data="+data, 
      success: function(server_response) { 
      $('.functions').ajaxComplete(function(event, request){ 

       if(server_response == 0) 
       { 
          var message = 'An email with instructions to reset password has been sent to your email address. Please check it.'; 
       } 
       else if(server_response == 1) 
       { 
          var message = 'Email address was not found in our database. Please enter a valid email address'; 
       } 
       else 
       { 
          var message = 'Some problem occured while sending you an email. Please try again.';          
       } 
    alert(message); 

    });

2種方式爲您提供：

$.ajaxSetup({ 
    cache: false, 
}); 

OR

$.ajax({ 
      type:"POST", 
      cache: false, 
      url: 'sample.php', 
      data:"data="+data, 
      success: function(server_response) { 
      $('.functions').ajaxComplete(function(event, request){ 

       if(server_response == 0) 
       { 
          var message = 'An email with instructions to reset password has been sent to your email address. Please check it.'; 
       } 
       else if(server_response == 1) 
       { 
          var message = 'Email address was not found in our database. Please enter a valid email address'; 
       } 
       else 
       { 
          var message = 'Some problem occured while sending you an email. Please try again.';          
       } 
    alert(message); 

    });

我在通過iOS設備查看網站時遇到了這個問題。它在某種程度上壓平了

cache: false 

設置。所以，我有嘗試和真正的黑客固定它：

var d = new Date(); 
$.ajax({ 
    url : "blah.php?"+d.getTime(), 
    cache: false, 
    ... 

我希望這可以幫助其他人面臨着同樣的問題。
