使用Google Maps API －添加线和实现线的单击事件,( 'clickable' GPolyline & GPolygon option)...-优快云博客

本文介绍了如何在Google Maps API中使用GPolylineOptions和GPolygonOptions设置'clickable'选项来控制多边形是否可点击，并提供了一个示例演示不同设置下的行为表现。

We've added a 'clickable' option to GPolylineOptions and
GPolygonOptions (not yet in the reference). The option is designed to
perform just as the 'clickable' option for GMarker, and thus defaults
to true. You can make your polygons not clickable by setting it to
false.

Here's a demo that compares clickable/event listener/non clickable
behavior across polys and markers:

Please let me know if you have any problems with the new option.

我的代码:
function addPolyline(latlon)
{
    var points = [];
    for(i=0;i<latlon.length-1;i++)
    {
        var simpleValue = latlon[i].split(",");
        var tmp = new String(simpleValue);
        var strlatlon = tmp.split(";");
        points.push(new GLatLng(strlatlon[1],strlatlon[0]));
    }
    var polyline = new GPolyline(points, "#FF0000", 3,1,{clickable: true});
    map.setCenter(points[0],16);

    //add Polyline
    GEvent.addListener(map, "click", function(overlay, latlng)
    {
        window.alert("You clicked the map at latlng: " + latlng + " and on overlay: " + overlay);
    });
    createPoly(points, true, true, true);
}

function createPoly(latlng, addListener, makePolyline, isClickable)
{
var polyLatLngs = latlng;

    if (makePolyline)
    {
        var poly = new GPolyline(polyLatLngs, '#0000ff',5, .7, {clickable: isClickable});
    }else
    {
        var poly = new GPolygon(polyLatLngs, '#0000ff', 1, 1.0, '#ff0000', .5, {clickable: isClickable});
     }
      map.addOverlay(poly);
}
