Hi Ads,<div><br></div><div>It kinda depends what parameters you want in there. The "featureAdded" handler is going to be a generic one, so it will have to get a lot of its information about the feature and so-on at its own runtime. However, what you probably want to do is use a closure:</div>
<div><br><div>var control = new OpenLayers.Control.DrawFeature(<br> someLayer, OpenLayers.Handler.Point, {<br> featureAdded: this.createFeatureAddedHandler(param1, param2)<br> });<br><br>...<br><br></div><div>function: createFeatureAddedHandler(param1, param2) {<br>
return function(feature) {<br>// In here you have access perpetually to the param1 and param2</div><div>// that were passed in when the handler was created.</div><div>}</div><div>}</div><div><br></div><div>If you'd like further information, the Wikipedia article has some good examples, despite the obtuse introduction: <a href="http://en.wikipedia.org/wiki/Closure_(computer_science)">http://en.wikipedia.org/wiki/Closure_(computer_science)</a></div>

Hi all,<br>
<br>
Is there a way I could add additional parameters to event listeners? Please<br>
refer to this example:<br>
<br>
var control = new OpenLayers.Control.DrawFeature(<br>
someLayer, OpenLayers.Handler.Point, {<br>
featureAdded: someFunction<br>
});<br>
<br>
...<br>
<br>
function: someFunction(feature, param2) {<br>
...<br>
}<br>
<br>
In the abovementioned example, how can I get the featureAdded event to<br>
insert additional parameters to the "someFunction" method?<br>
<br>
Thanks!!!<br>
<br>
