FW: [fusion-users] I dont know how zoom a point in fusion

[Paul Deschamps]

forgot to include the list :)

You can use parseFloat() js function as well. ;)

function zoomToExtents(minx,miny,maxx,maxy) {
    var a = [];
    a[0] = parseFloat(minx);
    a[1] = parseFloat(miny);
    a[2] = parseFloat(maxx);
    a[3] = parseFloat(maxy);

    var mapWidget = Fusion.getMapById('mapArea');
    var maps = mapWidget.getAllMaps();
    var map = maps[0];

    map.mapWidget.setExtents(new OpenLayers.Bounds(a[0], a[1], a[2],
a[3]));
}

Cheers
