Leaflet 小叶合并皱缩

我已经在我的网站上整合了传单。但是，如果我将贴图设置为折叠，则贴图不会完全可见

var mymap=L.map（'mapid'）.setView（[33.841954,10.995487]，11）；
const mainLayer=L.Tillelayer（'https://api.mapbox.com/styles/v1/{id}/tiles/{z}/{x}/{y}？access_token={accessToken}'，{attribute:'Map data©；contributors，images}'，maxZoom:18，enter:[33.841954,10.995487]，id:'mapbox/streets-v11'，tileSize:512，zoomofset:-1，accessToken:'accessToken}）；
mainLayer.addTo（mymap）；

展开视图后需要调用

map.invalidateSize（）

  var mymap = L.map('mapid').setView([33.841954, 10.995487], 11);
  const mainLayer = L.tileLayer('https://api.mapbox.com/styles/v1/{id}/tiles/{z}/{x}/{y}? access_token={accessToken}', { attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors, Imagery © <a href="https://www.mapbox.com/">Mapbox</a>', maxZoom: 18, enter: [33.841954, 10.995487], id: 'mapbox/streets-v11', tileSize: 512, zoomOffset: -1, accessToken: 'AccessToken'});
  mainLayer.addTo(mymap);
