Ajax調用不起作用

我有一個表單提交給JQuery和Ajax的PHP腳本。 PHP腳本返回一些XML。出於某種原因，Ajax成功函數不會觸發，而錯誤的是。Ajax調用不起作用

任何人都可以看到我要去哪裏錯了嗎？

我jQuery是如下

$('#submit-excuse').submit(function (event) { 
     event.preventDefault(); 
     ws_url = 'http://jacamo.epiphanydev2.co.uk/content/inc/excuse-submit.php?excuse='+$('input#excuse').val(); 
     $.ajax({ 
      type: 'GET', 
      url: ws_url, 
      dataType: "xml", 
      beforeSend: function() { 
       $('p#response').text('Sending.'); 
      }, 
      success: function(xmlIn) { 
       results = xmlIn.getElementsByTagName("ReportID"); 
      }, 
      error: function() { 
       $('p#response').text('Error.'); 
      } 
     }); 
    });

而且我的PHP腳本如下：

$excuse = $_GET['excuse']; 

$badwords = array (
    'one', 
    'two', 
    'three', 
    'four', 
    'five' 
); 

if ($excuse == '') { 
    $error = 'enter something'; 
} else {     
    foreach ($badwords as $word) { 
     $pos = strpos($excuse, $word); 
     if($pos !== false) { 
      $passed = false; 
     } 
    } 

    if ($passed !== false) { 
     $username = 'xxxxx'; 
     $password = 'xxxxx'; 

     $message = $excuse; 
     $url = 'http://twitter.com/statuses/update.xml'; 

     $curl_handle = curl_init(); 
     curl_setopt($curl_handle, CURLOPT_URL, "$url"); 
     curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2); 
     curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1); 
     curl_setopt($curl_handle, CURLOPT_POST, 1); 
     curl_setopt($curl_handle, CURLOPT_POSTFIELDS, "status=$message"); 
     curl_setopt($curl_handle, CURLOPT_USERPWD, "$username:$password"); 
     $buffer = curl_exec($curl_handle); 
     curl_close($curl_handle); 

     $passed = 'yes'; 
    } 

    echo "<?xml version='1.0' encoding='UTF-8'?>\n"; 
    echo "\t<result>\n"; 
    echo "\t\t<passed>" . $passed . "</passed>\n"; 
    echo "\t</result>"; 
}

感謝

什麼錯誤，你得到什麼？ – justkt 2010-04-26 13:35:48

'錯誤'功能有三個參數。將它們添加到你的函數，然後輸出它們。請參閱http://api.jquery.com/jQuery.ajax/ – 2010-04-26 13:41:26

jQuery是從您的查詢期望的XML響應回來。你需要發送XML頭。嘗試之前添加您的xml header ("content-type: text/xml");，看看是否可行

完美，對其進行排序。謝謝！ – Probocop 2010-04-26 14:11:42

AJAX不能用於跨域，爲此，請查看JSON。

這是我如何使用它：

jQuery的一面：

var server = ‘http://www.yoursite.com/path/to/map/’; 
var name = ‘Peter’; 
var lastname = ‘Marcoen’; 
$.getJSON(server+’getData.php?callback=?’,{name:name,lastname:lastname}, function(data) { 
alert(data); //Do your thing 
});

PHP端：

$name = $_REQUEST['name']; 
$lastname = $_REQUEST['lastname']; 
$return = ‘Hello ‘ . $name . ‘ ‘ . $lastname; 
echo $_GET['callback'] . ‘(’ . json_encode($return) . ‘)’;
