我在这里看到了很多这样的问题，但似乎没有一个能解决我的问题。我有一个通过查询填充的多维（嵌套）数组。我希望通过 AJAX jQuery 发送最终数组：
(function() {
var orderDetails = [];
orderDetails['retailer'] = [];
orderDetails['order'] = [];
db.transaction(function(qry){
qry.executeSql("SELECT * FROM retailers WHERE pending = '1' ", [], function(tx, results){
len = results.rows.length; //if rows.length, means retailer is pending so add details to array. If no length, means retailer exists
for (var i=0; i<len; i++){
console.log('start '+i+' loop in retailers qry');
orderDetails['retailer'][i] = [];
orderDetails['retailer'][i]['localID'] = results.rows.item(i).ID;
orderDetails['retailer'][i]['retailerName'] = results.rows.item(i).retailerName;
orderDetails['retailer'][i]['address'] = results.rows.item(i).address;
orderDetails['retailer'][i]['postcode'] = results.rows.item(i).postcode;
console.log('finish '+i+' loop in retailers qry');
}
}, function(err){console.log(err)})
}
这就是我填充数组的方式，这里是 AJAX 请求：
function(){
console.log('start orders qry success callback');
//alert(orderDetails['retailer'][0]['localID']);
var st = JSON.stringify(orderDetails['retailer']);
console.log(st);
$.ajax({//send retailer to server, bring back the ID of the retailer as it is on the server so we can insert it into the order
type: "POST",
cache: false,
//async: false,
url: "https://www.......processOrder.php",
data: { orderType: 'saved', orderDetails: st},
dataType: "json",
success: function(result){
}
})
});
当我在 ajax 请求之前记录上面的内容时，它会返回[[],[],[],[],[],[],[],[],[],[],[]]，所以我知道某些东西正在工作，我只是认为对象的全部内容将在服务器端可见。
此外，我将整个内容包装在一个匿名函数中，因为我认为这有助于数组变量范围。
