插入标记后如何清除Google Maps SearchBox?

问题描述

我正在尝试创建Google Maps版本,并希望在地图中插入标记后清理SearchBox

示例:我在地图上的意大利上放置了一个标记,但名称“意大利”仍保留在SearchBox中。为此,我需要手动清除搜索栏。

我的代码是:

function initAutocomplete() {
    const map = new google.maps.Map(document.getElementById("map"),{
      center: {
        lat: -15,lng: -55
      },zoom: 5,mapTypeId: "roadmap"
    }); // Create the search Box and link it to the UI element.

    const input = document.getElementById("pac-input");
    const searchBox = new google.maps.places.SearchBox(input);
    map.controls[google.maps.ControlPosition.TOP_LEFT].push(input); 

    // Bias the SearchBox results towards current map's viewport.

    map.addListener("bounds_changed",() => {
      searchBox.setBounds(map.getBounds());
    });
    let markers = []; 

    // Listen for the event fired when the user selects a prediction and retrieve
    // more details for that place.

    searchBox.addListener("places_changed",() => {
      const places = searchBox.getPlaces();

      if (places.length == 0) {
        return;
      } 

    // For each place,get the icon,name and location.

      const bounds = new google.maps.LatLngBounds();
      places.forEach(place => {
        if (!place.geometry) {
          console.log("Returned place contains no geometry");
          return;
        }

       const icon = {
       url: place.icon,size: new google.maps.Size(100,100),origin: new google.maps.Point(0,0),anchor: new google.maps.Point(17,34),scaledSize: new google.maps.Size(25,25)
       };

      // Create a marker for each place.

        markers.push(
          new google.maps.Marker({
            map,icon,title: place.name,position: place.geometry.location
          })
        );

        if (place.geometry.viewport) {
          // Only geocodes have viewport.
          bounds.union(place.geometry.viewport);
        } else {
          bounds.extend(place.geometry.location);
        }
      });
      map.fitBounds(bounds);
    });
  }

有人可以帮助我吗?
