如果单击事件侦听器创建了标记，则Google Maps拖动和拖动事件侦听器将不起作用
提问于 2012-07-09 15:08:38
这只是一个新手在尝试学习时，我遇到了一个问题，当我尝试使用单击事件创建标记时，拖动和拖动事件侦听器将不起作用。而在默认情况下创建时，它们可以正常工作。
这是我到目前为止所尝试过的。

var map;
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var myOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng);
});
}
function placeMarker(location) {
var marker = new google.maps.Marker({
position: location,
draggable:true,
map: map
});
map.setCenter(location);
}尝试像这样创建标记。
