Question

我创建了flightPath，但我不能使用它。我写功能控制台'123'，但不是吗......我怎么能使用flightPath？

const mapOptions = {
    //mapOption
};
const map = new google.maps.Map(document.getElementById('map'), mapOptions);

let flightPath = {};

function createPoint(e) {
  //createPoint
}

function createLineBetweenPoints() {
  const flightPathOptions = {
    //option
    map: map
  };
  flightPath = new google.maps.Polyline(flightPathOptions);
}

function createRoutes(e) {
  createPoint(e);
  createLineBetweenPoints(e);
}

map.addListener('click', createRoutes);

google.maps.event.addListener(flightPath, 'click', function() {
    console.log(123);// don't work
});

您正在尝试将Google地图事件监听器添加到空对象{}，但这不起作用。一旦存在，您需要将其添加到google.maps.Polyline。

function createLineBetweenPoints() {
  const flightPathOptions = {
    //option
    map: map,
  };
  flightPath = new google.maps.Polyline(flightPathOptions);
  google.maps.event.addListener(flightPath, 'click', function() {
    console.log(123);
  });
}

实时创建和删除flightPath
