我正在实现 Google Map API,并在 jQuery 对话框中显示 map 。 map 显示正常,但标记位置不在中心,所以请指导我。
如何使标记位置和 map 居中?
map 代码:
var myCenter = new google.maps.LatLng('@Model.Latitude', '@Model.Longitude');
function initialize() {
var mapProp = {
center: myCenter,
zoom: 15, mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
var marker = new google.maps.Marker({
position: myCenter,
draggable: false,
animation: google.maps.Animation.DROP,
});
marker.setMap(map);
}
打开对话框的代码:
$("#googleMap").dialog({
autoOpen: false,
height: 600,
width: 1000,
resizeStop: function (event, ui) {
google.maps.event.trigger(googleMap, 'resize')
}, open: function (event, ui) {
google.maps.event.trigger(googleMap, 'resize'); },
});
$("#btnLocation").click(function () {
$("#googleMap").dialog("open");
});
HTML:
<div id="googleMap" style="width: 1000px; height: 500px"></div>
<img src="map.jpg" alt="Set Location" id="btnLocation" style="cursor: pointer; height: 35px; width: 35px;" />
最佳答案
尝试以下操作:
1) 定义 map
和marker
函数外 initialize
,我们稍后将调用它们来使 map 居中
var myCenter = new google.maps.LatLng('@Model.Latitude', '@Model.Longitude');
// DEFINE YOUR MAP AND MARKER
var map = null, marker = null;
function initialize() {
var mapProp = {
center: myCenter,
zoom: 15, mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
marker = new google.maps.Marker({
position: myCenter,
draggable: false,
animation: google.maps.Animation.DROP,
});
marker.setMap(map);
}
2)修改对话框的“打开”事件,打开对话框时强制显示 map 中心:
$("#googleMap").dialog({
autoOpen: false,
height: 600,
width: 1000,
resizeStop: function (event, ui) {
google.maps.event.trigger(googleMap, 'resize')
},
// OPEN EVENT MODIFIED !
open: function (event, ui) {
google.maps.event.trigger(googleMap, 'resize');
// Force the center of the map
map.setCenter(marker.getPosition());
},
});
尝试一下,让我知道这是否有效;)
