Question

我有一个使用Jquery和Ajax提交到PHP脚本的表单。 PHP脚本返回一些XML。由于某种原因，Ajax成功函数没有触发，错误的是。

有人能看到我出错的地方吗？

我的Jquery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.');
            }
        });
    });

我的PHP脚本如下：

$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>";
}

Jquery期待从您的查询返回xml响应。您需要发送xml标头。尝试在xml header ("content-type: text/xml");之前添加并查看是否有效

Answer 2

AJAX不能在不同的域中使用，为此，请查看JSON。

这就是我使用它的方式：

JQuery方面：

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方：

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

Ajax调用不起作用
