How do you get the HTML contents of a widget into the c.data object?

[mikeszafranski]

One of my team-mates created a very nice HTML report widget in Service Portal.       Now the client would like to save a PDF copy of the report.   I know we can render HTML fields as PDF but how do you get the HTML contents of a widget back to the server side for further processing and attaching to a record?

Thanks for the advice.     I'be been playing around with html2canvas with nor progress.

Answer my own question:

In the HTML:

we tag the div with an ID

<div id = "preview">

We also add a button:

    <button type="submit" ng-click="c.canvas()" class="btn btn-primary">Canvas</button>

In the client script a function that is called by the button:

c.canvas = function preview(){

  c.data.myHTML = document.getElementById('preview').innerHTML;

  c.server.update();

  }
