我在 JavaScript 中创建 JSON 数组时遇到问题。我的源代码如下所示：

数组1：

aOrderInformations[0]         = BestellNummer;
aOrderInformations[1]         = Lieferant;
aOrderInformations[2]         = Bestellgrund;
aOrderInformations[3]         = Besteller;
aOrderInformations[4]         = Mitarbeiter;
aOrderInformations[5]         = Standort;
aOrderInformations[6]         = Gesellschaft;
aOrderInformations[7]         = Bestelldatum;
aOrderInformations[8]         = Begruendung;
aOrderInformations[9]         = Lieferanschrift;
aOrderInformations[10]        = Rechnungsanschrift;

aOrderInformations = new Array(aOrderInformations);

array2 来自带有 ajax 的服务器（这里是 PHP）：

$sQuery = "
    SELECT SQL_CALC_FOUND_ROWS ".str_replace(" , ", " ", implode(", ", $aColumns))."
    FROM   $sTable
    WHERE BestellID = '".$bestellid."'
    ORDER BY $sIndexColumn DESC
";

$rResult = mysql_query( $sQuery, $gaSql['link'] ) or die(mysql_error());

while ($data = mysql_fetch_array($rResult)) 
{ 
    $aPositions[] = $data; 
}  
echo json_encode( $aPositions );

array2（这里是 Javascript）：

success: function(data) {
    aPositions = data;

当我单独调试两个数组时，它将以正确的语法显示。但是当我尝试按如下方式将其发送到 php 时，它不会合并数组并仅显示一个数组：

{
  "0": {
    "0": "292",
    "1": "1",
    "2": "Microsoft",
    "3": "Maus",
    "4": "33355520",
    "5": "MISCO Germany Inc.",
    "6": "510014",
    "7": "1",
    "8": "22.02",
    "9": "22.02",
    "PostenID": "292",
    "ProduktID": "1",
    "Hersteller": "Microsoft",
    "Beschreibung": "Maus",
    "Produktnummer": "33355520",
    "Lieferant": "MISCO Germany Inc.",
    "Artikelnummer": "510014",
    "Menge": "1",
    "PreisNettoEinzeln": "22.02",
    "PreisNettoGesamt": "22.02"
  }
}

将组合数组发送到 php 的代码如下：

var postData = $.extend({}, aOrderInformations, aPositions);
var postData = JSON.stringify(postData);
if(!ajaxload2) {
    alert(postData);
    ajaxload2 = true;   
    $.ajax({
        type : 'POST',
        url : 'share/content/helper/writeorderdata.php',
        cache: false,
        dataType : 'json',
        data: {postData:postData},
        success: function() {
                        ajaxload2 = false;
        }
    });
}
