我想將文本添加到線串中。基本上,街道名稱在Google地圖中顯示的方式基本相同。所以如果我放大或移動地圖,文本仍然顯示在線上。mapbox如何添加標籤到線串?
我是否需要添加某種具有相同座標的新圖層?
這是一個jsfiddle開始。
<body>
<div id='map'></div>

mapboxgl.accessToken = 'pk.eyJ1Ijoib2tpZWJ1YmJhIiwiYSI6ImNpdHZscGs3ajAwNXYyb284bW4ydWUzbGsifQ.1PoNrSP0F65WolWgqKhV4g';
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v9',

});
map.on('load', function() {
map.addSource("route", {

});
map.addLayer({
