Question

enter code hereif ( vm.TaskLocation.length !=0)
        {
           alert("haii");
             var place = vm.TaskLocation;
            document.getElementById('latitudeId').value =place.geometry.location.lat();
            document.getElementById('longitudeId').value =place.geometry.location.lng();
            marker.setPosition(place.geometry.location);
            marker.setVisible(true);

        }

位置在vm.TaskLocation中，文本框在编辑部分填充此位置但标记位置未更改

我得到了答案

geocoder = new google.maps.Geocoder();
    var taskLocation = document.getElementById("taskLocation");
    //function in case of edit task.set map according to location in text box
    if(taskLocation  != 0)
    {
        var loc=[];
        // next line creates asynchronous request
        geocoder.geocode( { 'address': vm.TaskLocation}, function(results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                loc[0]=results[0].geometry.location.lat();
                loc[1]=results[0].geometry.location.lng();
                var mapOptions = {
                    center: new google.maps.LatLng(loc[0], loc[1]),
                    zoom: 15
                };
                map = new google.maps.Map(document.getElementById('map'),
                              mapOptions);
                marker = new google.maps.Marker({
                    position: new google.maps.LatLng(loc[0], loc[1]),
                    map: map,
                });
                document.getElementById('latitudeId').value =loc[0];
                document.getElementById('longitudeId').value =loc[1];
            } 
        }else {
                alert("Geocode was not successful for the following reason: " + status);
            }

如何在不使用自动完成或标记事件的情况下将位置加载到文本框中时在谷歌地图中设置标记位置？
