我正在尝试将我的数据库中位置的距离添加到一个名为距离的数组中。似乎我的数组在完成循环之前被清空了和/或循环的索引在每次循环完成之前没有重新分配“x”的值。你能看到我做错了什么吗？我需要某个地方的回调函数吗？

<?php if (isset($customer_id)) {?>
                        customer_id = <?=$customer_id?>;
                    <?php }?>

                    //var distances = new Array();

                        $j.ajax({
                            type: "POST",
                            url: "/ajax_calls/originDestinationAddress.php",
                            data: { 'vendorID': <?=$vendorId?>, 'customerID': customer_id}
                            }).done(function(data) {
                                var data= JSON.parse(data);     
                                var destination = data[0].destination;
                                console.log ('destination is ' + destination);

                                var distances = [];
                                for(var x=0; x<data.length; x++){
                                console.log('the array of distances for vendor with id ' + <?=$vendorId?>);
                                    var origin = data[x].origination;
                                    console.log('origin is ' + origin);

                                    if(origin && destination){
                                        var service = new google.maps.DistanceMatrixService();
                                          service.getDistanceMatrix(
                                            {
                                              origins: [origin],
                                              destinations: [destination],

                                                        var pieces = miles.split(" ");

                                                            console.log('currently adding ' + pieces[0] + ' to distances array with key ' + x);

哇，好难读啊！

它看起来像您标记为的花括号：

//end for length of data loop

实际上是结束括号：

if(origin && destination){

花括号直接位于：

console.log(distances);

是 data.length 循环的右括号。

我想你想做的是移动 console.log(distances)

到 .done() 回调结束之前的行，如下所示：

        }//end for length of data loop

    }
    console.log(distances);

});//end done function
