[OpenLayers-Users] Display WFS-Points as markers

[Arnd Wippermann]

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
});

Arnd

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)

Andy
