Hi,
That should it be.
function findcoords (event) {
var vertices = event.feature.geometry.getVertices();
alert('ID:' + vertices);
}

Betreff: Re: [OpenLayers-Users] Trying to draw a box on a map, and get the
coordinates back.
i am not sure i explained what i was looking for correctly. here is an
example.
vectors.events.register('featureadded', vectors, findcoords); function
findcoords (feature) {
var vertices = feature.geometry.getVertices();
document.getElementById('output').value = 'ID:' + vertices; }
the event does actually trigger, however, feature.geometry.getVertices()
does not work.
i am using geojson to display other polygons on the map, and would like the
variable vertices to get the coordinates of the polygon vertices so that i
can add a new polygon to the map and save the coordinates in a database.
