Question

在下面的代码中，我使用jQuery调用来阻止回复到aspx页面，即调用Google地图以获取客户指示。当我使用回车键而不是＆＃34; Directions＆＃34;按钮。页面刷新。我已经包含了一些jQuery，它应该将按键功能与按钮本身联系起来，但它仍然会导致回发。

我的问题是，我可以通过将按键功能绑定到该按钮来阻止回复此代码吗？

编辑1：我仍然需要允许用户按下回车键来执行搜索路线。

jQuery的：

<script>
        var directionDisplay;
        var directionsService = new google.maps.DirectionsService();

        function initialize() {
            directionsDisplay = new google.maps.DirectionsRenderer();
            var mapOptions = {
                zoom: 10,
                mapTypeId: google.maps.MapTypeId.ROADMAP,
                center: new google.maps.LatLng(31.320574, -85.70925),
            };
            var map = new google.maps.Map(document.getElementById('map-canvas'),
                mapOptions);
            directionsDisplay.setMap(map);
            directionsDisplay.setPanel(document.getElementById('directions-panel'));

            var control = document.getElementById('control');
            control.style.display = 'block';
            map.controls[google.maps.ControlPosition.TOP].push(control);

            var image = '../images/flag.png';
            var marker = new google.maps.Marker({
                position: new google.maps.LatLng(31.239661, -85.499698),
                map: map,
                icon: image
            });
        }

        function calcRoute() {
            var start = document.getElementById('txtAddress1').value;
            var end = "business location";
            var request = {
                origin: start,
                destination: end,
                travelMode: google.maps.DirectionsTravelMode.DRIVING
            };
            directionsService.route(request, function (response, status) {
                if (status == google.maps.DirectionsStatus.OK) {
                    directionsDisplay.setDirections(response);
                }
            });




            document.getElementById('map-canvas').style.display = 'inline-block';
        }
 $(document).ready(function () {
            $("form input").keypress(function (e) {
                if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) {
                    $('input[type=button] .NavButton').click();
                    return true;
                }
            });
        });
        google.maps.event.addDomListener(window, 'load', initialize);
    </script>

通过指定键功能输入密钥javascript来阻止回发
