我一直在尝试找到一种方法来设置放针以将焦点放在地图的中心，或者让地图进行调整以将放针的焦点集中在地图的中心。从下图可以看到，下降针显示在屏幕的左上角。以下是我当前正在处理的代码片段。

我目前正在使用leaftlet.js提供交互式地图

enter image description here 

$(document).ready(function() {

    var map = L.map('mapid').setView([14.5906216, 120.9799696], 12);

    L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
        attribution: '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'
    }).addTo(map);

    let geocoder = new L.Control.Geocoder.Nominatim();
    var location = $('.location').text();

    geocoder.geocode(location, function(results) {    
        var latLng = new L.LatLng(results[0].center.lat, results[0].center.lng);
        var marker = new L.Marker (latLng);
  

        var geocodeLocation = Object.values(latLng);
        // console.log(geocodeLocation);

        L.marker(geocodeLocation).addTo(map)
        .bindPopup('A pretty CSS3 popup.<br> Easily customizable.')
        .openPopup()



    });
})
