Hello,
I am not quite sure if I understood you right. You want to access
attributes of a clicked line segment? If this is your problem this code
snippet should help you:
// your style code is skipped here
// ...
//
// here I build some example features with attributes
var g1 = new OpenLayers.Geometry.LineString([new
OpenLayers.Geometry.Point(0, 0), new OpenLayers.Geometry.Point(10, 10)]);
var g2 = new OpenLayers.Geometry.LineString([new
OpenLayers.Geometry.Point(10, 10), new OpenLayers.Geometry.Point(25, 30)]);
var f1 = new OpenLayers.Feature.Vector(g1,
{firstAttrribute: 'firstValue', secondAttribute: 'secondValue'});
var f2 = new OpenLayers.Feature.Vector(g2,
{firstAttrribute: 123, secondAttribute: 456});
// from here on this is your corrected code
features = [f1, f2];
result_linea.addFeatures(features);
var options = new
OpenLayers.Control.SelectFeature(result_linea, {
hover: false,
highlightOnly: true,
clickout: true,
onSelect: function(feature){
console.log(feature);
for (var key in feature.attributes) {
// access the key and value of the clicked
line's attributes
alert(key+ ': ' + feature.attributes[key]);
}
},
selectStyle: linea_style2
});
map.addLayers([result_linea]);
map.addControl(options);
options.activate();
map.zoomToMaxExtent();
Best regards,
Chris

HI!!
i need assign data to a segmet (painted with vector class), so when i
click on it return to me the assigned data .... can you help me please?
this is my code.
var linea_style = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
linea_style.strokeWidth = 6;
linea_style.strokeColor = "#ff0000";
linea_style.strokeOpacity = 0.5;
var linea_style20 = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
linea_style.strokeWidth = 7;
linea_style.strokeColor = "blue";
linea_style.strokeOpacity = 0.5;
result_linea = new OpenLayers.Layer.Vector(
"Routing results",
{style: linea_style});
map.addLayer(result_linea);
features=[a lot of segment];
result_linea.addFeatures(features);
var options= new OpenLayers.Control.SelectFeature(result_linea, {
hover: false,
highlightOnly: true,
clickout:true,
onSelect: function(feature) {
//alert(feature);
for (var us in feature ){
//campo va tomando los nombres de
las propiedades
alert( feature[us] );
}
},
selectStyle: linea_style2
});
map.addControl(options);
options.activate();
that part I can assign the data?
