如何在每次 XML 调用服务器后更新 html 表而不刷新页面？

Question

我有一个加载了 50 行的 mySQL 表。每行都有处理信用卡所需的信息。当用户点击处理信用卡时，查询表格并使用 html 显示页面上的每一行。一旦数据显示在页面上，脚本将开始处理通过商家帐户的每一行，并将相应的行变为红色表示拒绝或绿色表示批准，而无需在每次交易后刷新页面。我认为我需要使用 AJAX 或 jQuery 来实现这一点，但我不确定我是否朝着正确的方向前进。这是处理交易的脚本：

<?php
$request = new GatewayRequest();
$response = new GatewayResponse();
$service = new GatewayService();


$request->Set(GatewayRequest::MERCHANT_ID(), "111111111111111");
$request->Set(GatewayRequest::MERCHANT_PASSWORD(), "xxxxxxxxxxxx");


$time = time();
$request->Set(GatewayRequest::MERCHANT_CUSTOMER_ID(), $time . '.PHPTest');
$request->Set(GatewayRequest::MERCHANT_INVOICE_ID(), $time . '.SaleTest');



$request->Set(GatewayRequest::AMOUNT(), "9.99");
$request->Set(GatewayRequest::CARDNO(), "4111111111111111");
$request->Set(GatewayRequest::EXPIRE_MONTH(), "02");
$request->Set(GatewayRequest::EXPIRE_YEAR(), "2010");
$request->Set(GatewayRequest::CVV2(), "999");


$request->Set(GatewayRequest::CUSTOMER_FIRSTNAME(), "Joe");
$request->Set(GatewayRequest::CUSTOMER_LASTNAME(), "PHPTester");
$request->Set(GatewayRequest::EMAIL(), "phptest@fakedomain.com");
$request->Set(GatewayRequest::IPADDRESS(), $_SERVER['REMOTE_ADDR']);


$request->Set(GatewayRequest::BILLING_ADDRESS(), "123 Main St");
$request->Set(GatewayRequest::BILLING_CITY(), "Las Vegas");
$request->Set(GatewayRequest::BILLING_STATE(), "NV");
$request->Set(GatewayRequest::BILLING_ZIPCODE(), "89141");
$request->Set(GatewayRequest::BILLING_COUNTRY(), "US");




$request->Set(GatewayRequest::SCRUB(), "IGNORE");
$request->Set(GatewayRequest::CVV2_CHECK(), "IGNORE");
$request->Set(GatewayRequest::AVS_CHECK(), "IGNORE");

$service->SetTestMode(TRUE);

if ($service->PerformPurchase($request, $response)) {
  print "Purchase succeeded\n";
  print "Response Code: " .
    $response->Get(GatewayResponse::RESPONSE_CODE()) . "\n";
  print "Reasone Code: " .
    $response->Get(GatewayResponse::REASON_CODE()) . "\n";
  print "Auth No: " . $response->Get(GatewayResponse::AUTH_NO()) . "\n";
  print "AVS: " . $response->Get(GatewayResponse::AVS_RESPONSE()) . "\n";
  print "CVV2: " . $response->Get(GatewayResponse::CVV2_CODE()) . "\n";
  print "GUID: " . $response->Get(GatewayResponse::TRANSACT_ID()) . "\n";
  print "Account: " .
    $response->Get(GatewayResponse::MERCHANT_ACCOUNT()) . "\n";
  print "Scrub: " .
    $response->Get(GatewayResponse::SCRUB_RESULTS()) . "\n";
} else {
  print "Purchase failed\n";
  print "GUID: " . $response->Get(GatewayResponse::TRANSACT_ID()) . "\n";
  print "Response Code: " .
    $response->Get(GatewayResponse::RESPONSE_CODE()) . "\n";
  print "Reasone Code: " .
    $response->Get(GatewayResponse::REASON_CODE()) . "\n";
  print "Exception: " .
    $response->Get(GatewayResponse::EXCEPTION()) . "\n";
  print "Scrub: " .
    $response->Get(GatewayResponse::SCRUB_RESULTS()) . "\n";
}

?>

这种类型的代码是否可以在不重写的情况下与 AJAX 或 jQuery 一起使用？任何帮助将不胜感激。

任何东西都可以在不被重写的情况下工作，但是你已经为自己设置了很多麻烦。通过将所有这些打印语句格式化为一个数组并对其进行 JSON 编码，您可能会获得更好的运气（并节省大量时间）。显然 javascript 喜欢 JSON。
