AJAX沒有通過javascript呼應

Question

好吧，所以我想讓PHP將用戶數據保存到XML中，然後將用戶轉發到主頁上..但是當JavaScript運行時，它不會在最後抓取回顯腳本以及header（）;

的PHP我願重申

echo "<b>Congratulations registration was Successful.<br /> Your Customer ID is: $id4</b>"; 
      echo "<br/>"; 
      echo "redirected automatically in 7 seconds"; 
      header("Refresh:7; buyonline.htm", true, 303); 
      $doc->save("data/customer.xml"); 
     } 

以及JavaScript函數

var firstname = document.getElementById("firstName").value; 
      var lastname = document.getElementById("lastName").value; 
      var email = document.getElementById("email").value; 
      var password = document.getElementById("password").value; 
      var password2 = document.getElementById("password2").value; 
      var number = document.getElementById("pNumber").value; 
      var type = ""; 
      var input = document.getElementsByTagName("input"); 
       xHRObject.open("GET", "testregristation.php?firstName=" + firstname + "&lastName=" + lastname + "&email=" + email + "&password="+password+"&pNumber="+number, true); 
       xHRObject.onreadystatechange = function() { 
        if (xHRObject.readyState == 4 && xHRObject.status == 200) 
        { 
         document.getElementById('information').innerHTML = xHRObject.responseText; 
        } 
       xHRObject.send(null); 

顯然，這些都是小片段，但我不明白爲什麼它不會發送到屏幕的響應它顯示了響應在「螢火蟲」..我的PHP也做了電子郵件檢查，以確保它沒有被使用，並且完美的回聲。

我還沒有真正測試過你的代碼，以確保我要說的是100％正確。 我從來沒有試圖在ajax響應中以這種方式使用標題。 但是，我想如果你想重定向用戶只是使用JavaScript的。

PHP：

echo "<b>Congratulations registration was Successful.<br /> Your Customer ID is: $id4</b>"; 
echo "<br/>"; 
echo "redirected automatically in 7 seconds"; 
$doc->save("data/customer.xml"); 

的Javascript：

if (xHRObject.readyState == 4 && xHRObject.status == 200) 
{ 
    document.getElementById('information').innerHTML = xHRObject.responseText; 
    setTimeout(function() 
    { 
     window.location.pathname = "/buyonline.htm"; 
    }, 7000 /* 7 seconds */); 
} 

編輯： 現在，因爲你使用JavaScript重定向的頁面，你也可以倒計時秒：

PHP：

echo "<b>Congratulations registration was Successful.<br /> Your Customer ID is: $id4</b>"; 
echo "<br/>"; 
echo "redirected automatically in <span id="redirect-countdown">7 seconds</span>"; 
$doc->save("data/customer.xml"); 

的Javascript：

if (xHRObject.readyState == 4 && xHRObject.status == 200) 
{ 
    document.getElementById('information').innerHTML = xHRObject.responseText; 

    var countdown = document.getElementById("redirect-countdown"); 

    var count = 8; 
    var interval = setInterval(function() 
    { 
     count--; 

     countdown.innerText = count + " second" + (count > 1 ? "s" : ""); 

     if(count <= 0) 
     { 
      clearInterval(interval); // Kill the interval timer 
      window.location.pathname = "/buyonline.htm"; // Redirect to that page 
     } 

    }, 1000); 
}
