您好我正在使用谷歌地图和algolia,我有一个索引' locations'与' lat'和' lng'。
我正在获取用户位置和观看位置,我也在显示基于lng和lat的数据库中的标记但是我想为它添加一点:
所以我已经关注了这个链接:
https://www.algolia.com/doc/guides/geo-search/geo-search-overview/
并提出:

和js:
$(document).ready(function() {
var map;
function initializeMap(){
map = new google.maps.Map(document.getElementById('map_canvas'), {
zoom: 19,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
}
function locError(error) {
// the current position could not be located
alert("The current position could not be found!");
}
function setCurrentPosition(position) {
currentPositionMarker = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(
position.coords.latitude,
position.coords.longitude

title: "Current Position"
});
map.panTo(new google.maps.LatLng(
position.coords.latitude,
position.coords.longitude
));
}
var latitude = position.coords.latitude;
var longitude = position.coords.longitude;
console.log(latitude);
console.log(longitude);
function displayAndWatch(position) {
// set current position
setCurrentPosition(position);
// watch position
watchCurrentPosition(position);
console.log(position);
}
function watchCurrentPosition(position) {
var positionTimer = navigator.geolocation.watchPosition(
function (position) {
setMarkerPosition(

function setMarkerPosition(marker, position) {
marker.setPosition(

}
function initLocationProcedure() {
initializeMap();
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(displayAndWatch, locError);
}else{

}
}
$(document).ready(function() {

});
var APPLICATION_ID = '75RQSC1OHE';
var SEARCH_ONLY_API_KEY = 'f2f1e9bba4d7390fc61523a04685cf12';
var INDEX_NAME = 'locations';
var PARAMS = { hitsPerPage: 100 };
// Client + Helper initialization
var algolia = algoliasearch(APPLICATION_ID, SEARCH_ONLY_API_KEY);
var algoliaHelper = algoliasearchHelper(algolia, INDEX_NAME, PARAMS);
// Map initialization
var markers = [];
//alert("heelo");
var fitMapToMarkersAutomatically = true;
algoliaHelper.on('result', function(content) {
renderHits(content);
var i;
// Add the markers to the map
for (i = 0; i < content.hits.length; ++i) {
var hit = content.hits[i];
console.log(hit)
var marker = new google.maps.Marker({
position: {lat: hit.longitude, lng: hit.latitude},
map: map,
title: hit.slug
});
markers.push(marker);
}
// Automatically fit the map zoom and position to see the markers
if (fitMapToMarkersAutomatically) {
var mapBounds = new google.maps.LatLngBounds();
for (i = 0; i < markers.length; i++) {
mapBounds.extend(markers[i].getPosition());
}
map.fitBounds(mapBounds);
}
});
function renderHits(content) {
$('#container').html(JSON.stringify(content, null, 2));
}
algoliaHelper.setQueryParameter('aroundRadius', 5000).search(); // 5km Radius
});
然而,这方面的问题很少,我不知道如何解决:
答案 0 :(得分:3)
我无法帮助你解决这些问题,因为它主要是关于如何使用GMap JS lib而我没有经验。然而,其他东西吸引了我的眼睛:
var marker = new google.maps.Marker({
position: {lat: hit.longitude, lng: hit.latitude},
map: map,
title: hit.slug
});
您应该将坐标放在_geoloc
字段中,以便能够使用地理搜索功能。它看起来像这样:
_geoloc: {
lat: 40.639751,
lng: -73.778925
}
