jquery - Google map 标记不在中心

Question

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;" />

Answer 1

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；)
