如何使用javascript从DataList EditItem模板获取文本框ID？

Question

我正在尝试添加谷歌地图自动填充，但我没有找到文本框ID。 我在datallist edititem模板中有文本框控件。在datalist之外，它工作得很完美，但是从datalist edititem模板获取Textbox id。

        

          google.maps.event.addDomListener（窗口，＆＃39;加载＆＃39;，函数（）{

        var places = new google.maps.places.Autocomplete(document.getElementById("<%= txtAddress.ClientID %>"));
        google.maps.event.addListener(places, 'place_changed', function () {
            var place = places.getPlace();
            var address = place.formatted_address;
            var latitude = place.geometry.location.A;
            var longitude = place.geometry.location.F;
            //var mesg = "Address: " + address;
            //mesg += "\nLatitude: " + latitude;
            //mesg += "\nLongitude: " + longitude;
            //alert(mesg);
        });
    });
</script>
