Google地图标记不在中心位置

问题描述

我正在实施Google Map API,并使用jQuery对话框显示地图。地图显示正常,但标记位置不在中心,所以请引导我。



我如何制作标记位置和地图中心?

地图代码:

  var myCenter = new google.maps.LatLng('@ Model.Latitude','@Model.Longitude ); 

函数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 =googleMapstyle =width:1000px; height:500px>< / div> 
< img src =map.jpgalt =设置位置id =btnLocationstyle =cursor:pointer; height:35px; width:35px; />


解决方案

请尝试以下操作:

1)在函数<$ c $外定义 map marker c> initialize ,我们稍后会调用它们来放置地图中心

  var myCenter = new google.maps.LatLng('@ Model.Latitude','@ Model.Longitude'); 

//定义您的地图和标记
var map = null,marker = null;

函数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)将对话框的打开事件修改为打开对话框时强制地图中心:

  $(#googleMap)。dialog({
autoOpen:false,
height:600,
width:1000,
resizeStop:function(event,ui){
google.maps.event.trigger(googleMap, '调整大小')
},
// OPEN EVENT MODIFIED!
open:function(event,ui){
google.maps.event.trigger(googleMap,'resize' );

//强制地图中心
map.setCenter(marker.getPosition());
},
});

请尝试让我知道这是否有效;)


I am implementing Google Map API and I show the map in jQuery Dialog Box. The Map is showing fine but the marker position in not in center, SO please guide me.

How can I make the marker position and map in center?

Code for the map:

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);
}

Code opening the dialog box:

$("#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;" />
解决方案

Try the following:

1) Define map and marker outside the function initialize, we'll call these later to center the map

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) Modify the "open" event of the dialog box to force the map center when opening the dialog box:

$("#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());
    },
});

Have a try and let me know if this works ;)
