我想在地图上有一个默认标记来指示地址,而用户可以将用户标记拖到他们认为正确的位置。 (适用于某些地图修正情况......)
<script type="text/javascript"><!--
var geocoder;
var map;
var point;
function mapLoad() {
geocoder = new google.maps.Geocoder();
var myOptions = {
zoom: 16,
mapTypeControl: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map"), myOptions);
var address = "LS2 2RD"; //default postcode
geocoder.geocode( { 'address':address,region:"UK",language:"en"}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
point=results[0].geometry.location;
map.setCenter(point);
var defaultMarker = new google.maps.Marker({map: map, position: point}); //default marker
var marker = new google.maps.Marker({
map: map,
position: point,
draggable: true
}); //The marker for users to drag
var DefaultContent ='<h4>Default Location</h4><h6>You can drag it to anywhere you think it is right or confirm here is the right place</h6><div class="confirm"><input type="button" value="This location is correct"></div>'
var DefaultInfo = new google.maps.InfoWindow({content: DefaultContent,maxWidth:200});
DefaultInfo.open(map,marker); //default infowindow
var TargetContent='<h4>New Location</h4><h6>Are you sure here is the right place?</h6><div class="confirm"><input type="button" value="Yes, I confirm" />'+
'<input type="button" value="Cancel" onclick="clsMark()" /></div>'; //here cancel button is not working
var infobox = new google.maps.InfoWindow({content: TargetContent}); //after drag ended, the new infowindow
google.maps.event.addListener(marker, 'drag', function(){
DefaultInfo.close();
});
google.maps.event.addListener(marker, 'dragend', function() {
infobox.open(map, marker);
});
function clsMark(){if (infobox != null) {infobox.close();}//if user cancel, clear the infowindow, and put the marker back to default position
marker.setPosition(point);}
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
问题是我无法在infowindow中使用这些按钮。我无法使用以下命令将click事件绑定到按钮:
google.maps.event.addListener(buttonID, 'click', function(){...}
如果我在按钮上添加onclick,我会得到函数未定义的错误,就像上面的代码一样,在这种情况下它表示“clsMark未定义”。
所以我完全不知道如何在infowindow中使用按钮。请帮帮我...
答案 0 :(得分:1)
你声明clsMark()函数里面传递给geocoder.geocode()的匿名函数,这就是为什么它在全局范围内不可用(onclick处理程序正在寻找它)。
尝试在 geocoder.geocode调用之前移动函数clsMark(),使其对onclick处理程序可见。
至于你尝试使用'addListener(buttonID,..',请注意addListener不能使用ID,你必须提供'object'作为第一个参数,所以这只能使用谷歌地图对象。
