You can style your features by attributes
see
http://openlayers.org/dev/examples/styles-context.html
// create the layer styleMap by giving the default style a context
var colors = ["red", "green", "blue"];
var context = {
getColor: function(feature) {
var region = parseInt((feature.geometry.x + 180) / 120);
return colors[region];
},
getSize: function(feature) {
return feature.attributes["type"] / map.getResolution() * ..703125;
}
};
var template = {
pointRadius: "${getSize}", // using context.getSize(feature)
fillColor: "${getColor}" // using context.getColor(feature)
};
var style = new OpenLayers.Style(template, {context: context});
var layer2 = new OpenLayers.Layer.Vector('Points', {
styleMap: new OpenLayers.StyleMap(style),
renderers: renderer
});

Betreff: Re: [OpenLayers-Users] Display WFS-Points as markers
Uh! That looks very promising!
Thanks again Arnd!
Now im wondering if there is a feature like "getElementsByTagName" (found in
an example for GeoRSS)?
That would allow for a dynamic construction for the features (e.g tooltip or
externalGraphic)
Regards,
Andy
