AW: [OpenLayers-Users] pick an attribute from a wms layer when I draw a point in another vector layer

[Arnd Wippermann]

Hi,
 
register featureadded for your vector layer:
 
 
yourLayer.events.register("featureadded", yourLayer, function (e){

    comunePickFunc(e) 
/*
    var lon = e.feature.geometry.x;
    var lat = e.feature.geometry.y;
    var w   = 5*map.resolution;
    BBOX = (lon-w) + "," + (lat-w) + "," + (lon+w) + "," + (lat+w);
 
window.open("someServer&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&QUE
RY_LAYERS=[layers]&LAYERS=[layers]&BBOX=" + BBOX +
"&SRS=EPSG:31466&X=50&Y=50&WIDTH=100&HEIGHT=100&FORMAT=image/png&INFO_FORMAT
=text/html&FEATURE_COUNT=1&STYLES=");
*/
});

Arnd

Betreff: [OpenLayers-Users] pick an attribute from a wms layer when I draw a
point in another vector layer


Hi all,
I've a function "A"[0] for picking an attribute from a wms layer, the value
is passed to a form.
I've another function "B"[1] for draw and save a point in a postgis table
(via geoserver), this function is triggered when I click the form "save"
button.
Function A works fine except when I want to insert a new point.
I want the function A to be triggered when drawing a point on the map...but
I don't know how!
Some suggestion?

thanks a lot
