基础用法

<template>
  <div id="container1" style="width: 100%; height: 500px; position: relative">
    <div style="position: absolute; top: 0px; left: 0px; z-index: 1000">
      <button @click="start">开始</button>
      <button @click="end">结束</button>
    </div>
  </div>
</template>
<script>
import { transform } from "ol/proj";

import * as utilsol from "@gis-js/utilsol"
export default {

      map: null,
      animation: null,
    };
  },
  mounted() {
    var center = [37.41, 8.82];

    this.map = new Map({

      view: new View({
