Question

我正在尝试实施谷歌地图Jquery版本，即GMAP3

我从以下c＃代码

调用脚本

修改

void drawMap(List<beatWithCurrentStatus> mapList, bool IsMap)
{       
    ScriptManager.RegisterStartupScript(this, this.GetType(), "functiona", "designMap(" + ConvertToJSON(mapList) + ");", true);
}

以下是我的脚本

function designMap(JSONData) {
var ll = [];
var address = [];

for (var i = 0; i < JSONData.length; i++) {
    //        ll[i] = '{latLng:\'[' + data[i].lastlatitude + ',' + data[i].lastlongitude + ']\',data:\'' + data[i].lastaddress + '\'}';
    ll[i] = { latLng: [JSONData[i].lastlatitude, JSONData[i].lastlongitude], data: JSONData[i].lastaddress };
}
alert(ll);
$('#mapDiv').gmap3({
    map:
{
    options: {
        center: [JSONData[5].latitude, JSONData[5].longitude],
        zoom: 7,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        mapTypeControl: true,
        mapTypeControlOptions: {
            style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
        },
        navigationControl: true,
        scrollwheel: true,
        streetViewControl: true
    }

},
    marker: {
        values: ll,
        options: {
            draggable: false
        }
    }

});
}

编辑：这是我从ConvertToJSON（mapList）函数

获得的JSON

EDIT2：

string ConvertToJSON(List<beatWithCurrentStatus> receivePoints)
{
    JavaScriptSerializer jss1 = new JavaScriptSerializer();
    return jss1.Serialize(receivePoints);
}

我应该如何传递地图中的标记???请帮忙..！我已经尝试了所有方法，但没有一个工作。但是，如果我对值进行硬编码，它会显示在地图上。

请帮助.. :(

Answer 1

ll的项目不是对象，您创建字符串（无法像对象一样访问）请改用：
```
ll[i] = {latLng:[JSONData[i].lat,JSONData[i].lng],data:JSONData[i].address};
```
将ll直接传递给标记的values-property，而不是作为数组的项目（ll已经是数组）

    marker: {
        values: ll,
        options: {
            draggable: false
        }
    }

这些是2个必需的修改，当它仍然无法工作时，你必须至少发布JSONData

从后面的代码在地图上显示标记
