I am trying to do the rule based styling in openlayers 3, here is my code:
<!DOCTYPE html>
<html>
<head>
<title>CONFIG</title>
<script src="https://code.jquery.com/jquery-1.11.2.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="http://openlayers.org/en/v3.8.2/css/ol.css" type="text/css">
<script src="http://openlayers.org/en/v3.8.2/build/ol.js"></script>
</head>
<body>
<div class="container-fluid">
<div class="row-fluid">
<div class="span12">
<div id="map" class="map"></div>
</div>
</div>
<script>
var layerStyle = {
default: {
style: new ol.style.Style({
stroke: new ol.style.Stroke({
color: 'rgba(0, 0, 0, 1.0)',
width: 0.5
}),
fill: new ol.style.Fill({
color: 'rgba(0, 255, 0, 0.5)'
})
})
},
filter: [{
type: "AND",
rules: [{
type: "==",
property: "CODE",
value: "16"
}, {
type: "==",
property: "NAME",
value: "CHIKMAGALUR"
}],
symbolizers: {
style: new ol.style.Style({
stroke: new ol.style.Stroke({
color: 'rgba(0, 255, 0, 0.5)',
width: 0.5
}),
fill: new ol.style.Fill({
color: 'red'
})
})
}
} ]
};
var geojson_layer = new ol.layer.Vector({
source: new ol.source.Vector({
url: 'file.geojson',
format: new ol.format.GeoJSON()
}),
});
var vectorLayer = new ol.source.Vector({
features: (new ol.format.GeoJSON()).readFeatures(geojsonObject)
});
if ('CODE'=='16' && 'NAME'=='CHIKMAGALUR') {
style: symbolizers;
}
var map = new ol.Map({
layers: [
new ol.layer.Tile({
source: new ol.source.OSM()
}),
vectorLayer,
],
target: 'map',
controls: ol.control.defaults({
attributionOptions: /** @type {olx.control.AttributionOptions} */ ({
collapsible: false
})
}),
view: new ol.View({
center: [0, 0],
zoom: 5
})
});
</script>
</body>
</html>
I am trying trying to get the style from symbolizer, but I am getting error. Like openlayer2 I used the filters for AND operation but I stucked. Can someone help me on this??

In OL3 vector layers have a style attribute that can be a Style object, an array of Style objects or a function that returns a Style object or an array of Style objects. You probably want to use a style function for what you are trying to do.
See the following example for how this can be done:
