Question

这是我的Jquery代码

function kirimgambar(chatboxtitle) {

    var file = jQuery( ".pilih" ).val();
    if(file==""){ 
    jQuery("#chatboxtextarea").focus();
    }else {
    jQuery("#loading")
    .ajaxStart(function(){
        jQuery(this).show();
    })
    .ajaxComplete(function(){
        jQuery(this).hide();
    });

    jQuery.ajaxFileUpload
    (
        {
            url:'http://localhost:8080/diobatin/application/views/chat/chat.php?action=kirimfile',
            secureuri:false,
            fileElementId:'fileToUpload',
            dataType: 'json',
            data:{name:'logan', id:'id', chatboxtitle:chatboxtitle},
            success: function (data, status)
            {
                if(typeof(data.error) != 'undefined')
                {
                    if(data.error != '')
                    {
                        alert(data.error);
                    }else
                    {
                        alert(data.msg);
                    }
                }
            },
            error: function (data, status, e)
            {
                alert(e); //This ouput is "syntax error unexpected token <"
            }
        }
    )
    chatHeartbeatTime = minChatHeartbeat;
    chatHeartbeatCount = 1;
    return false;   
    }

}

在chat.php中

    function kirimfile() {
    $error = "";
    $msg = "";
    $fileElementName = 'fileToUpload';
    if(!empty($_FILES[$fileElementName]['error']))
    {
        $error = 'No file was uploaded..';
    }elseif(empty($_FILES['fileToUpload']['tmp_name']) || $_FILES['fileToUpload']['tmp_name'] == 'none')
    {
        $error = 'No file was uploaded..';
    }else 
    {
            $upload_path = "./asset/";
            if (!is_dir($upload_path)) {
                mkdir($upload_path);
            } 

             $file = $_FILES['fileToUpload']['name'];
             $tmp  = $_FILES['fileToUpload']['tmp_name'];
                // jika $file ada dan tidak kosong
                if ((isset($file)) && ($file != "")) { 
                    // handle apabila sudah ada file sama yang terupload, maka akan dibuat copynya
                    $uploadfile = (file_exists($upload_path.$file)) ? $upload_path." copy of ".$file : $upload_path.$file;
                    move_uploaded_file($tmp, $uploadfile);
                    if (chmod($uploadfile, 0775)) {
                        $from = $_SESSION['username'];
                        $to = $_POST['chatboxtitle'];
                        $message =  $_SESSION['username'];
                        $messagesan = sanitize($message);

    if (!isset($_SESSION['chatHistory'][$_POST['to']])) {
        $_SESSION['chatHistory'][$_POST['to']] = '';
    }

    $_SESSION['chatHistory'][$_POST['to']] .= <<<EOD
                       {
            "s": "1",
            "f": "{$to}",
            "m": "{$messagesan}"
       },
EOD;
    unset($_SESSION['tsChatBoxes'][$_POST['to']]);          

                        }
            }
    }
    echo '<meta http-equiv="Content-type" content="text/html; charset=UTF-8">';
    echo "{\n";
    echo                "error: '" . $error . "',\n";
    echo                "msg: '" . $msg . "'\n";
    echo "}";
}

alern上的此输出返回语法错误意外令牌＆lt; chrome 但是在 mozilla firefox 错误报告是 未声明框架文档的字符编码。如果在没有文档框架的情况下查看，该文档可能会显示不同。

<meta http-equiv="Content-type" content="text/html; charset=UTF-8">和\n不是JSON。

替换

echo '<meta http-equiv="Content-type" content="text/html; charset=UTF-8">';
echo "{\n";
echo                "error: '" . $error . "',\n";
echo                "msg: '" . $msg . "'\n";
echo "}";

使用

$arr = array(
            'error' => $error,
            'msg'   => $msg
        ); 

echo json_encode($arr);

如何修复语法错误意外令牌＆lt; ，在jQuery.ajaxFileUpload上
