JScript code


//同步坐标
        function synchronizationCoordinate() {
            var url = "http://maps.google.com/maps/api/geocode/json?address=" + encodeURIComponent($('#<%= txtAddress.ClientID %>').val()) + "&sensor=false" + "&randomNum=" + Math.random();
            $.ajax({
                url: url,
                dataType: 'json',
                success: function(data) {
                    if (data.status == 'OK') {
//经度
                        $('#<%= txtLongitude.ClientID %>').val(data.results[0].geometry.location.lng);
//纬度
                        $('#<%= txtLatitude.ClientID %>').val(data.results[0].geometry.location.lat);
                    }
