# POSTMESSAGE

#### Syntax

**POSTMESSAGE**(*message*)

* *message* - the text message which should be sent to the browser page - ***Value type**: text*

#### Remark

* The message is sent to the browser page after the current formula evaluation has been completed.
* The parent page should have a windows.addEventListener function to receive this message (see example below).

#### Example

Add this script tag to your parent page to receive the message which has been sent by the POSTMESSAGE function:

```
<script >
      function handleMessage(event) {
      // Log the received message
      console.log('Received message:', event.data);
    }
    window.addEventListener('message', handleMessage);
</script>

```

Instead of the console.log function you could add any custom code to process *message* in the expected way.
