.Ajax 中是否有 If 来前置或附加？

 $.ajax({  
    type: "GET",  
    url: "../pgs/authenticate.php", 
    data: "FirstName="+ sFirstName +"&SurName="+ sSurname +"&NextOKin=" + sNOK ,  
    success: function(html){$("#Ajax_response").prepend(html);}    
        });

我只想在身份验证失败时“前置”，否则只是：

  success: function(html){$("#Ajax_response").html(html);}

这可能吗？

        });

I only want to "prepend" IF the authentication fails else just:

  success: function(html){$("#Ajax_response").html(html);}

Is this possible?

在 PHP 脚本中，您可以执行以下操作：

// on this part you decide based on your checks if it's true (or false)
// and what to return as content e.g. based on your authentication checks
$Success = true;
$Content = 'Some HTML';

$Response = array('Success' => $Success, 'Content' => $Content);
echo json_encode($Response);

在 JS 中：

success: function(result)
{
   // if true
   if (result.Success)
      $("#Ajax_response").html(result.Content);
   // false (FAIL)
   else
      $("#Ajax_response").prepend(result.Content);          
}

我希望这能给您一个想法。

}

I hope that gives you an idea.

if (html.match("/Failed/"))
{
$("#Ajax_response").prepend(html);
}

这会在 Ajax 响应 html 中查找单词 Failed，如果找到则执行操作。显然，您知道失败响应将包含什么以及您需要查找什么字符串。

if (html.match("/Failed/"))
{
$("#Ajax_response").prepend(html);
}

This looks for the word Failed in the Ajax response html and does the action if found. Obviously you know what the failure response will contain and what string you need to be looking for.
