地点详情紧凑元素(预览版)和地点详情元素(实验性)是用于呈现地点详情的 HTML 元素:
-
PlaceDetailsCompactElement
(预览版)旨在占用最少的空间,并显示一组简洁的地点信息,包括名称、地址、评分等。它还可以包含一张照片。 -
完整尺寸的
PlaceDetailsElement
(实验性)支持更多内容元素,包括网站、电话号码、编辑摘要、评价等,还可以包含多张照片。
地点详情紧凑元素(预览版)
PlaceDetailsCompactElement
会使用最少的空间呈现所选地点的详细信息。这在以下场景中可能很有用:在信息窗口中突出显示地图上的位置;在社交媒体体验中(例如在聊天中分享位置)提供建议;作为选择当前位置的建议;或在媒体文章中引用 Google 地图上的位置。PlaceDetailsCompactElement
可以显示名称、地址、评分、类型、价格、无障碍图标、营业状态和一张照片。
如需将该元素添加到地图,请在 HTML 页面上的 gmp-map
元素中添加 gmp-place-details-compact
元素,并使用 orientation
属性设置其屏幕方向。
在以下示例中,gmp-place-details-compact
嵌套在 gmp-map
元素中,orientation
设置为 horizontal
。其他属性 truncation-preferred
会截断某些内容,使其适合在一行中显示,而不是换行。
<gmp-map center="47.75972, -122.25094" zoom="19" map-id="DEMO_MAP_ID"> <gmp-place-details-compact orientation = "horizontal" truncation-preferred slot="control-block-start-inline-center" > <gmp-place-details-place-request place = "ChIJC8HakaIRkFQRiOgkgdHmqkk"></gmp-place-details-place-request> <gmp-place-content-config> <gmp-place-media lightbox-preferred></gmp-place-media> <gmp-place-rating></gmp-place-rating> <gmp-place-type></gmp-place-type>\ <gmp-place-price></gmp-place-price> <gmp-place-accessible-entrance-icon></gmp-place-accessible-entrance-icon> <gmp-place-open-now-status></gmp-place-open-now-status> <gmp-place-attribution light-scheme-color="gray" dark-scheme-color="white"></gmp-place-attribution> </gmp-place-content-config> </gmp-place-details-compact> <gmp-advanced-marker></gmp-advanced-marker> </gmp-map>
gmp-place-details-compact
元素包含一个子元素 gmp-place-details-place-request
,用于选择地点。这可以是地点对象、地点 ID,也可以是地点的资源名称(格式为“places/{place_id}”):
<gmp-place-details-place-request place = "ChIJC8HakaIRkFQRiOgkgdHmqkk"></gmp-place-details-place-request>
您可以使用嵌套的 gmp-place-content-config
元素选择和配置地点详情,从而控制 gmp-place-details-compact
元素显示的特定地点内容。gmp-place-content-config
元素本身包含多个子内容元素,每个元素都会选择要显示的相应地点详情:PlaceAddressElement
选择地点的地址,PlacePriceElement
选择地点的价格水平等。子元素的顺序无关紧要,因为所选详情始终以固定的预定义顺序呈现。
其中部分元素可以使用内容专用属性进行进一步配置:
-
gmp-place-media
元素用于显示单张照片,并包含一个lightbox-preferred
属性,该属性会在用户点击时在灯箱中打开照片。默认情况下,相册灯箱功能处于停用状态。 -
gmp-place-attribution
元素用于显示照片的来源。light-scheme-color
和dark-scheme-color
属性用于设置浅色和深色模式下的提供方说明文本的颜色。

地点详情元素(实验性)
完整尺寸的
PlaceDetailsElement
支持更多内容元素,包括完整的营业时间、网站、电话号码、编辑摘要、类型专用亮点、评价、代码和功能列表。
-
configureFromPlace
方法会根据地点 ID 或Place
对象呈现地点详情元素。 -
configureFromLocation
方法会根据纬度和经度坐标渲染地点详情元素。
本部分中的示例会在用户点击地图时呈现“地点详情”元素。如需在地图上添加地点详情,请向 HTML 页面添加 gmp-place-details
元素。分别使用 size
和 slot
属性设置其大小和位置。在以下示例中,它嵌套在 gmp-map
元素中,其中 size
设置为 x-large
,slot
设置为 control-inline-start-block-start
。
<gmp-map center="47.759737, -122.250632" zoom="16" map-id="DEMO_MAP_ID"> <div class="widget-container" slot="control-inline-start-block-start"> <gmp-place-details size="x-large"></gmp-place-details> </div> <gmp-advanced-marker></gmp-advanced-marker> </gmp-map>
querySelector
用于选择要与之互动的每个网页元素:
const map = document.querySelector('gmp-map'); const placeDetails = document.querySelector('gmp-place-details'); const marker = document.querySelector('gmp-advanced-marker');
以下代码段中的事件处理脚本会根据用户点击地图的位置呈现地点详情元素:
// Add an event listener to handle map clicks. map.innerMap.addListener('click', async (event) => { marker.position = null; event.stop(); if (event.placeId) { // Fire when the user clicks a POI. await placeDetails.configureFromPlace({ id: event.placeId }); } else { // Fire when the user clicks the map (not on a POI). await placeDetails.configureFromLocation(event.latLng); } // Get the offset center. let adjustedCenter = offsetLatLngRight(placeDetails.place.location, -0.005); // Show the marker at the selected place. marker.position = placeDetails.place.location; marker.style.display = 'block'; map.innerMap.panTo(adjustedCenter); }); }
