Hi again, there is a way that I can erase everything in the map? I have multiple markers, tracks, and drawings, but I need a button that clean all the map, i've tried to delete the markers but if i make another action with the same marker it draws the lines of the previous action.  
Just when I make a change and deploy, the map reboots.

```auto
[{"id":"5cc9f26d.ec485c","type":"inject","z":"ed175afd.1609d8","name":"","topic":"","payload":"{\"command\":{\"clear\":true}}","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":110,"y":400,"wires":[["89b9bc86.d241c"]]}]

```

Here is my flow, any help is welcome.

Taken from the nodes readme

#### To clear all markers from a layer, or an overlay from the map

```auto
msg.payload.command.clear = "name of your layer/overlay to remove";

```

Hi, thanks for the reply, I've tried it, but it does nothing, and when i put a msg.payload debug it gives "undefined"

Please let people know what version of Node, Node-RED and world-map you are using.

An example flow with test data is also useful so that other people can verify the issue.

Hi, my bad, I'm in Node-Red 0.20.5, and node-red-contrib-web-worldmap 2.0.12  
This is what I need:  
 ![Selection_022](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/f/f997eccf6acc2f76e3b8b2e05f9842ad7539f218.png)  
But i need that the second time, make another action, another route, but instead makes this:  
 ![Selection_023](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/9/93ab0c13996e72cc05c6ced27645ae3ad65b2ede.png)  
And when I inject the msg.payload.command.clear = "mylayer";  
the console gives this: TypeError: Cannot set property 'clear' of undefined  
I'm i doing it wrong?

Thanks.

According to the docs the clear command takes a layer or overlay name. I think you gave it "true" in the original flow. You also sent a payload type of "str" which I'm not sure is correct.

Without the flow that creates the map, hard to debug it.

You have additional commands such as being able to [remove the base layer](https://github.com/dceejay/RedMap#to-switch-layer-move-map-and-zoom) or [delete specific items](https://github.com/dceejay/RedMap#to-remove-base-or-overlay-layers).

So you may need to try a few more things?

I've tried remove the marker separately and removes it, but if i make the other action makes the same thing.  
I also tried the remove layer with the msg.payload in command and it does nothing, thats what i tried with str, but same result.  
And when i delete specific items, it removes it, but in the moment i inject the action of the marker, same result. The only way when it clean all the map is when i deploy the flow again, thanks anyway, i'll keep trying what the documentation says, maybe i'm ignoring something.

Well, if you can put together a small, stand-alone flow to create a map and overlay I'll happily test a couple of things as well if you like.

I'm using worldmap in dashboard with the examples I've found, in the question i'm putting my flow, i just need to clean all markers and tracks with a button and click the button of the marker again, but it doesn't reset with nothing, let me try to make a flow more simple and put it here. Thanks.

@TotallyInformation You can test with this flow, all i need is click the button that makes marker moves, clear marker and tracks, click again the button but with everything reset.

The overlays don't appear to have been set correctly:

Which may be why they don't clear?

Yup. I cleared one by passing "unknown" as the layer name,

Here is where you name one of the layers:

Your other function doesn't include the "layer" name so comes out as "unknown".

Hi,

if you send a msg.payload with just the name and deleted set true to both the track node and the map node it will delete the track and name of that point.  
eg - `msg.payload = {name:"Jason", deleted:true};`

The message to clear the whole layer in your example is `msg.payload = {command:{clear:"unkwon" }};`

So combining those gives  
`msg.payload = {name:"Jason", deleted:true, command:{clear:"unkwon" }};`

But yes - the layer delete does not delete things from the track node - or rather the track node doesn't recognise that command which would be sensible in order to remove multiple tracks in one go. So yes I have now fixed the code - version 2.0.17 on npm  
Your example with a delete button as per below
