Question

我有这个表格，我想用地址，用户的地理位置自动填写地址，城市，州和邮政编码输入字段，我是javascript区域的菜鸟，我真的需要帮助。

这是我的代码，我需要帮助创建填充字段的javascript。

<form name="catcustomcontentform11679" onsubmit="return checkWholeForm11679(this)" enctype="multipart/form-data" method="post" action="/CustomContentProcess.aspx?CCID=24718&amp;OID={module_oid}&amp;OTYPE={module_otype}">

您可以尝试这样做:(您可能希望为用户提供输入该地址的选项。对于这样的情况，例如，订购时不在家，有朋友家，工作等等。不想用实际的纬度和经度填写那里的地址，而是像这个例子所显示的那样帮助缩小范围。

var placeSearch, autocomplete;
var componentForm = {
  route: 'long_name',
  locality: 'long_name',
  administrative_area_level_1: 'short_name',
  postal_code: 'short_name'
};

function initialize() {
  // Create the autocomplete object, restricting the search
  // to geographical location types.
  autocomplete = new google.maps.places.Autocomplete(
    /** @type {HTMLInputElement} */
    (document.getElementById('autocomplete')), {
      types: ['geocode']
    });
  // When the user selects an address from the dropdown,
  // populate the address fields in the form.
  google.maps.event.addListener(autocomplete, 'place_changed', function() {
    fillInAddress();
  });
}

// [START region_fillform]
function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();

  for (var component in componentForm) {
    document.getElementById(component).value = '';
    document.getElementById(component).disabled = false;
  }

  // Get each component of the address from the place details
  // and fill the corresponding field on the form.
  for (var i = 0; i < place.address_components.length; i++) {
    var addressType = place.address_components[i].types[0];
    if (componentForm[addressType]) {
      var val = place.address_components[i][componentForm[addressType]];
      document.getElementById(addressType).value = val;

Answer 2

您可能会发现，根据用户提供的纬度/经度稍微命中或遗漏，为用户填充地址行。

在具有GPS装置的设备上，位置应该非常准确，但有时可能会错过建筑物编号。没有GPS的设备有时会给出一个大概的位置，有时可能相当远。

这可能会给您的用户带来一些摩擦，必须编辑或删除您预先填充的文字。

另外还要考虑当有些人使用他们的移动设备时，他们可能会远离家乡，因此它会使用当前位置的信息填充字段，而不是他们想要使用的地址。

如果您想加快输入地址的速度，使用邮政编码来解决查询服务可能是更好的选择。
