javascript - Google Place Autocomplete Address API 强制 HTML Autocomplete = Off

Question

我们有一个标准的地址表格(街道 1、街道 2、城市、州、邮政编码、国家/地区)。

当我在 Street 1 添加 Google Places Autocomplete API 的代码时，它会在加载页面时自动将输入字段的自动完成更改为关闭，这使得 HTML/浏览器自动填充在 Street 1 上不起作用。

<input autocomplete="address-line1" type = "text" name = "shipping_address_1" id = "shipping_address_1"   class="ct-required form-control" tabindex=7>

关于如何纠正这个问题的任何想法；为什么 Google Place Autcomplete API 会将字段更改为 autocomplete='off'？

我曾尝试将 Google javascript 变量“autocomplete”修改为“autocomp”，认为它与此有关，但结果仍然相同。

      var placeSearch, autocomp;
  var componentForm = {
    shipping_address_1: 'short_name',
    shipping_address_2: 'long_name',
    shipping_city: 'long_name',
    shipping_state: 'short_name',
    shipping_country: 'long_name',
    shipping_zip: 'short_name'
  };



  function initAutocomplete() {
    // Create the autocomplete object, restricting the search to geographical
    // location types.
    autocomp = new google.maps.places.Autocomplete(
        /** @type {!HTMLInputElement} */(document.getElementById('shipping_address_1')),
        {
            types: ['geocode'],
            componentRestrictions: {country: "us"}
        });

    // When the user selects an address from the dropdown, populate the address
    // fields in the form.
    autocomp.addListener('place_changed', fillInAddress);
  }

  function fillInAddress() {
    // Get the place details from the autocomplete object.
    var place = autocomp.getPlace();
    //debug autofillinplaes
    console.log(place);


    for (var component in componentForm) {
      document.getElementById(component).value = '';
      document.getElementById(component).disabled = false;
    }

if (place.address_components) {
    // Get each component of the address from the place details
    // and fill the corresponding field on the form.

    var components_by_type = {};

    for (var i = 0; i < place.address_components.length; i++) {
      var addressType = place.address_components[i].types[0];
      var c = place.address_components[i];
      components_by_type[c.types[0]] = c;

    }
     var streetnumb = components_by_type['street_number'].short_name;

          var address1 = streetnumb+" "+components_by_type['route'].long_name;
            document.getElementById('shipping_address_1').value = address1;

         var locality = components_by_type['locality'].long_name;     
        document.getElementById('shipping_city').value = locality;

         var administrative_area_level_1 = components_by_type['administrative_area_level_1'].short_name;      
        document.getElementById('shipping_state').value = administrative_area_level_1;

          var country = components_by_type['country'].short_name;             
        document.getElementById('shipping_country').value = country;

          var postal_code = components_by_type['postal_code'].short_name;         
        document.getElementById('shipping_zip').value = postal_code;
... [DO ADDRESS VALIDATION, UPDATE INPUT FIELDS] ...}

Answer 1

autocomp = new google.maps.places.Autocomplete(
document.getElementById('shipping_address_1')),
        {
            types: ['geocode'],
            componentRestrictions: {country: "us"}
        });

通过编写上面的代码，您告诉 GMaps 这是您需要预测地点的字段。它有点像地点的搜索栏，任何类型的搜索栏都不会自动完成。如果它由浏览器自动填充，那将没有任何意义。

如果您希望采用这种方式，请使用 WebService API，发送 HTTP 请求并用其响应填充字段。

来自文档，对以加利福尼亚州旧金山为中心的区域内包含字符串“Amoeba”的企业的请求:https://maps.googleapis.com/maps/api/place/autocomplete/xml?input=Amoeba&types=establishment&location=37.76999,-122.44696&strictbounds&key=YOUR_API_KEY使用查询参数 input=Paris&types=geocode 对上述 URL 的 GET 请求将提供包含预测的 JSON 对象。

               "offset" : 0
            }
         ],
    ... more results
    ]
