I use openlayers 2 in my project.
I draw 3 types of features on the map after drawing is complete I need to trigger function named featureDrawed.
Her is my code:
drawControl = {
point: new OpenLayers.Control.DrawFeature(new OpenLayers.Layer.Vector("Point Layer"), OpenLayers.Handler.Point } }),
line: new OpenLayers.Control.DrawFeature(new OpenLayers.Layer.Vector("Line Layer"), OpenLayers.Handler.Path),
polygon: new OpenLayers.Control.DrawFeature(new OpenLayers.Layer.Vector("Polygon Layer"), OpenLayers.Handler.Polygon)
}
for (var key in drawControl) {
control = drawControl[key];
controls.push(control);
}
Here is the html where user select the feature to draw:
<div data-role="popup" id="popupShapes" data-theme="none" style="z-index:999">
<div data-role="collapsibleset" data-theme="b" data-content-theme="a" style="margin:0; width:250px;">
<div data-role="listview" data-inset="false">
<ul data-role="listview">
<li>
<input type="radio" name="type" value="point" id="pointToggle" />
<label for="pointToggle">draw point</label>
</li>
<li>
<input type="radio" name="type" value="line" id="lineToggle" />
<label for="lineToggle">draw line</label>
</li>
<li>
<input type="radio" name="type" value="polygon" id="polygonToggle" />
<label for="polygonToggle">draw polygon</label>
</li>
</ul>
</div>
</div>
</div>
And here is event that fired after user select the shape to be drawn.
$("#popupShapes ul li input").click(function () {
var val = $(this).val();
for (key in drawControl) {
var control = drawControl[key];
if (val == key) {
control.activate();
} else {
control.deactivate();
}
}
});
The code is works fine. But the problem is that I can't create event that fired after feature is draw on the map.
Declare the function to be called on draw end:
var onDrawEnd = function(e) {
console.log('feature added', e.feature);
//your logic
};
Register a listener for each control:
for (var key in drawControl) {
control = drawControl[key];
control.events.register('featureadded', null, onDrawEnd);
controls.push(control);
}
