[OpenLayers-Users] Draw a point and assign a dynamic label to it

[Kris Geusebroek]

Hi Kristian,

You have to do something like this (this function is called in the
onChange of a textbox)

function changeDescription(val) {
	if (popupFeature) {
		popupFeature.attributes.OMSCHRIJVING = val;
		if ((!popupFeature.state || popupFeature.state ==
OpenLayers.State.UNKNOWN)) {
			popupFeature.state = OpenLayers.State.UPDATE;
		}
	}
}

Popupfeature is the feature that is currently modified
OMSCHRIJVING is an attribute (column in the database)

This way you're label can be rendered with the Style of the layer
automatically and stored in the db

Cheers kris

Subject: [OpenLayers-Users] Draw a point and assign a dynamic label to
it


Hi list

In my map I have added a vector layer and a drawFeature control.
The drawFeature is set to draw points, and works without problems.

Now, I would like to assign a text-label to the point's style.
The text in the label should be defined by the user (through a prompt()
or
other alternatives).

So I was thinking about settings this value in the "featureAdded" event
of
the drawFeature control, but I can't quite figure out how to do this.
When I try to do it like this...
var point = new OpenLayers.Control.DrawFeature(
  vectorLayer,
  OpenLayers.Handler.Point,
  {
    type: OpenLayers.Control.TYPE_TOOL,
    featureAdded: function(event) {
      event.style.label = 'test';
      redliningLayer.drawFeature(event);
    }
  }
);
... I just get an error message:
event.style is null
So if anyone has an idea of how to do this, it would be appreciated :)
