我正在使用谷歌地图 - 方向和地理编码。页面加载时,地理编码会放置标记。当用户点击提交按钮时,是否可以删除此标记?我之前问过,有人建议使用:
marker.setMap(空);
但我不太确定在哪里放置那段代码
以下是代码:
var address = document.getElementById("address").textContent.replace(/\n/g, " ");
geocoder.geocode( { 'address': address},
function(results, status)
{
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
}
else
{
alert("Geocode was not successful for the following reason: " + status);
}
});
var from = document.getElementById("from").value;
var to = document.getElementById("to").value;
var request = {
origin: from,
destination: to,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
document.getElementById("map").style.width = "70%";
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
提前致谢
答案 0 :(得分:1)
提交按钮在哪里?
<input type="Submit" value="Submit" onclick="marker.setMap(null);" />
这假设marker.setMap(null);
当然有用。
