用於在 Google 地圖上產生多個停止方向的 Vue.js 實現

Question

我編寫了這部分程式碼來在Google地圖上顯示方向 但目前我只有開始和結束位置 我想要有更多的站點並讓路線盡可能好 如何輸入多個停靠點？ 到目前為止我就是這麼做的

<table>
        <tr>
          <th>Start</th>
          <th><GmapAutocomplete @place_changed="setPlace" /></th>
          <th style="width: 50%;"><button class="btn" @click="addMarker(0)">Add</button></th>
        </tr>
        <tr>
          <th>End</th>
          <th><GmapAutocomplete @place_changed="setPlace" /></th>
          <th style="width: 50%;"><button class="btn" @click="addMarker(1)">Add</button></th>
        </tr>
      </table>

方向組件

import { MapElementFactory } from "vue2-google-maps";
export default MapElementFactory({
  name: "directionsRenderer",
  ctr() {
    return window.google.maps.DirectionsRenderer;
  },
  events: [],
  mappedProps: {},
  props: {
    origin: { type: [Object, Array] },
    destination: { type: [Object, Array] },
    travelMode: { type: String },
  },
  afterCreate(directionsRenderer) {
    console.log(1)
    let directionsService = new window.google.maps.DirectionsService();
    this.$watch(
      () => [this.origin, this.destination, this.travelMode],
      () => {
        let { origin, destination, travelMode } = this;
        if (!origin || !destination || !travelMode) return;
        directionsService.route(
          {
            origin,
            destination,
            travelMode,
          },
          (response, status) => {
            if (status !== "OK") return;
            // eslint-disable-next-line no-debugger
            //debugger
            directionsRenderer.setDirections(response);
          }
        );
      }
    );
  },
});

<DirectionsRenderer
        travelMode="DRIVING"
        :origin="startLocation"
        :destination="endLocation"
      />

還有我的功能

setPlace(place) {
      this.currentPlace = place;
    },
    addMarker(index) {
      const marker = {
        lat: this.currentPlace.geometry.location.lat(),
        lng: this.currentPlace.geometry.location.lng(),
      };
      if (index === 0) this.startLocation = marker;
      if (index === 1) this.endLocation = marker;
      this.center = marker;
      console.log(this.startLocation, this.endLocation)
    },

所以到目前為止我一切都很好%E

我以前遇到過這個問題，這會對您有所幫助：

首先，您需要將 waypoints 和 optimizeWaypoints 鍵新增至 DirectionsRenderer.js 檔案中的 directionsService.route 之後，您需要將此鍵綁定到專案中的 DirectionsRenderer 元件，並且需要在元件檔案中建立一個名為 waypnt 的數組，並將所有 Destination 點和 ##
