I have a script which takes data from html and uses it to plot routes on a map. I'm trying to get it to take all the routes and zoom to show all of them. Here's the code:

var ombounds = new google.maps.LatLngBounds(); //bounds
    for (var r=1; $("#master-master > div").length; r++)
    {
        // Add a placemark at the start of each route
        var placemark_id = "#master-" + r + " > #placemarks-data > #placemark-0";

        var markerParameters = {};
        markerParameters.index = r-1;
        markerParameters.total = $(placemark_id + " > .total").html();
        markerParameters.mapData = $(placemark_id + " > .map").html();
        markerParameters.instructionsData = $("#master-" + r + " > #snippet").html();
        markerParameters.distanceData = $("#master-" + r + " > #distance").html();
        markerParameters.durationData = $("#master-" + r + " > #duration").html();
        markerParameters.titleData = $("#master-" + r + " > #title").html();
        markerParameters.urltitleData = $("#master-" + r + " > #url-title").html();
        markerParameters.imageData = $(placemark_id + " > .image").html();

        $.OverMap.addMarker(markerParameters);

        // Draw route
        var points = new Array();
        var pointsData = [];
        var pointsData = $('#master-' + r + ' > #route-data').html();
        if (pointsData != '')
        {
            var pointsArray = JSON.parse(pointsData);
            for (var p=0; p<pointsArray.length; p++) {
                var pt = new google.maps.LatLng(pointsArray[p][0], pointsArray[p][1]);
                points.push(pt);
                ombounds.extend(pt); //bounds
            }
            $.OverMap.drawRoute(points);

        }
        else $.OverMap.drawDirections({preserveViewport:false});
    }
    (map.getBounds()); //bounds
    map.fitBounds(ombounds); //bounds

For some reason, map.fitBounds(ombounds) does nothing. The code still plots the routes, but I can't see what the bounds related functions are doing. I've added //bounds to all the lines related to the zooming - at the moment, they have no visible affect on the code's output. Anyone know where I'm going wrong?

当preserveViewport方向服务的选项设置为 false 时，对 DirectionsRenderer 的每次调用都会缩放地图并将其置于其结果的中心。如果您希望 fitBounds 覆盖它，则需要将其设置为 true。
