多个Google自动填充和地方搜索问题

Question

我需要一些有关Google Maps API以及使用自动填充和地址完成的帮助.

这是我目前的代码:

JS

function fillInAddress(show) {
                    console.log(show);
                    var place = autocomplete.getPlace();
                    for (var i = 0; i < place.address_components.length; i++){
                        var base = place.address_components[i].types[0];
                        if(base === "postal_code"){
                            console.log(place.address_components[i].long_name);
                        }
                    }
                }

function initialize(out) {
            autocomplete = new google.maps.places.Autocomplete(
                    (document.getElementById(out)),
                    {types: ['geocode']});
            google.maps.event.addListener(autocomplete, 'place_changed', function () {
                fillInAddress(out);
            });
        }
        initialize("from");
        initialize("to");

HTML

<input type="text" id="from" class="location">
<input type="text" id="to" class="location">
<input id="fromPc" type="text">
<input id="toPc" type="text">

地点下拉列表工作正常,允许您输入,然后将提出建议.

但是当我点击from输入中的一个建议时,我在控制台中收到此错误.

Uncaught TypeError: Cannot read property 'address_components' of undefined

但是,当我在"输入"框中执行此操作时,它可以正常工作并返回邮政编码.

如果我然后返回第一个输入"from"然后再次输入地址,它会返回一个邮政编码,但它会从第二个输入"to"返回邮政编码.

有谁知道如何解决这个问题.

我提前感谢您的帮助!

你正在覆盖autocomplete里面的(全局)变量initialize.

将变量置于局部内部initialize并将其作为参数传递给fillInAddress

function fillInAddress(show,ac) {

                    var place = ac.getPlace();
                    for (var i = 0; i < place.address_components.length; i++){
                        var base = place.address_components[i].types[0];
                        if(base === "postal_code"){
                            document.getElementById(show+'Pc').value
                              = place.address_components[i].long_name;
                              return;
                        }
                    }
                }

function initialize(out) {
           var  autocomplete = new google.maps.places.Autocomplete(
                    (document.getElementById(out)),
                    {types: ['geocode']});

            google.maps.event.addListener(autocomplete, 'place_changed', 
               function () {
                document.getElementById(out+'Pc').value='';
                fillInAddress(out,autocomplete);
            });
        }
initialize("from");
initialize("to");
