[libreoffice online] insert text in document programmatically

tdias · January 17, 2019, 12:34pm

Hello!
I Want to write a string in the document programmatically when the user click in a button or menu. (like custom fields in libreoffice)

I tried with JS and cannot find a solution because of the data rendering in images by Libreoffice online.

Anyone know if it’s possible and how can I do that?
Thanks

There is an example how to do that with PostMessage.
Please take an eye to the following url.

github.com

LibreOffice/online/blob/master/loleaflet/html/framed.doc.html

<!DOCTYPE html>

<!-- Proof of concept of running loleaflet.html in an iframe. Also
     shows how to, from outside the iframe, invoke Python scripting in
     the underlying LibreOffice instance that manipulates the document
     being edited.

     This demonstrates using the Python InsertText.py and Capitalise.py
     scripts from javascript across iframes.
-->

<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Online Editor</title>

    <script>

      function post(msg) {
        window.frames[0].postMessage(JSON.stringify(msg), '*');

In this url, there is a method called “insertText” that may be be very usefull.
