带有扩展element的全屏控件

发布于 2022-11-30 23:36:03 字数 3433 浏览 0 评论 0 收藏 0

本示例演示带有明确选项参数的全屏控件。

点击右上角全屏控制按钮地图进入全屏模式（不包括右侧面板）。再点击一次，关闭全屏模式。

如果地图上没有全屏按钮，那么说明你的浏览器不支持全屏 API

main.js

import 'ol/ol.css';
import Map from 'ol/Map';
import OSM from 'ol/source/OSM';
import TileLayer from 'ol/layer/Tile';
import View from 'ol/View';
import {FullScreen, defaults as defaultControls} from 'ol/control';

const view = new View({
  center: [-9101767, 2822912],
  zoom: 14,
});

const map = new Map({
  controls: defaultControls().extend([
    new FullScreen({
      source: 'fullscreen',
    }),
  ]),
  layers: [
    new TileLayer({
      source: new OSM(),
    }),
  ],
  target: 'map',
  view: view,
});
