Question

我点击按钮后尝试在谷歌地图中插入标记。实际上我已将参数传递给addmarker（）函数。仍然没有显示标记。我提供了我的源代码。

function initialize() {
    var myLatlng = new google.maps.LatLng(23.684994000000000000,           90.356330999999950000);
    var mapOptions = {
        zoom: 4,
        center: myLatlng
    }
    var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
}

function addmarker(Clientlatitude, Clientlongitude) {
    var latilongi = new google.maps.LatLng(Clientlatitude, Clientlongitude);
    var marker = new google.maps.Marker({
        position: latilongi,
        map: this
    });
}

google.maps.event.addDomListener(window, 'load', initialize);

<input id="btnMarkerInseart" type="button" value="Insert" onclick='<%# "addmarker(" +Eval("latitude") + ", " +Eval("longitude") + ");" %>' />

你应该在初始化函数之外声明你的map变量，然后在创建标记时在你的addmarker函数中引用它，如下所示：

var map;

function initialize() {
    var myLatlng = new google.maps.LatLng(23.684994000000000000,           90.356330999999950000);
    var mapOptions = {
        zoom: 4,
        center: myLatlng
    }
    map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
}

function addmarker(Clientlatitude, Clientlongitude) {
    var latilongi = new google.maps.LatLng(Clientlatitude, Clientlongitude);
    var marker = new google.maps.Marker({
        position: latilongi,
        map: map
    });
}
