Question

我正在尝试将数据库中位置的距离添加到名为distance的数组中。似乎我的数组在完成它的循环之前被清空和/或循环的索引没有在每个循环完成之前重新分配'x'的值。你能看出我做错了什么吗？我是否需要某处的回调功能？

<?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(

哇，这很难读！

它看起来像你标记为的大括号：

//end for length of data loop

实际上是关闭支柱：

if(origin && destination){

大括号直接位于：

之后

console.log(distances);

是data.length循环的结束括号。

我认为您要做的是移动console.log(distances)

到你的.done（）回调结束之前的那一行：

        }//end for length of data loop

    }
    console.log(distances);

});//end done function
