我正在使用google maps api。我希望有兩個鼠標事件可以一次觸發。以下是代碼片段。多個鼠標事件不會觸發
function initialize() {
var myLatlng = new google.maps.LatLng(37.4419, -122.1419);
var myOptions = {
zoom: 13,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var polyOptions = {
strokeColor: '#000000',
strokeOpacity: 1.0,
strokeWeight: 3 }
poly = new google.maps.Polyline(polyOptions);
poly.setMap(map);
// Add a listener for the click event
google.maps.event.addListener(map, 'click', addLatLng);
}
function addLatLng(event) {
var path = poly.getPath();
if(!draw)
{
path.push(event.latLng);
path.push(event.latLng);
draw = true;
// Add a new marker at the new plotted point on the polyline.
var marker = new google.maps.Marker({
position: event.latLng,
title: '#' + path.getLength(),
map: map });
google.maps.event.addListener(map, 'mousemove', moveTrackLine);
}
else
{
path.push(event.latLng);
var marker = new google.maps.Marker({
position: event.latLng,
title: '#' + path.getLength(),
map: map });
draw = false;
}
}
function moveTrackLine(event) {
var path = poly.getPath();
// replace the old point with a new one to update the track
path.pop();
path.push(event.latLng);
}
當我第一次在地圖上點擊地圖時點擊地圖。然後,當鼠標移動時,我看到多段線更新並正確地跟隨我的光標。接下來,如果我點擊地圖,我看不到放置在地圖上的標記,也不會進入addLatLng函數。預先感謝您的幫助和時間。 -tim
