Requirement: Extract text out of rich text editor control text on a Dynamics 365 CE Record form.

Here is the script for this example (written on change event):

function onChange(executionContext)
{

var formContext = executionContext.getFormContext();
formContext.getAttribute("new_plaintextwithhtml").setValue(formContext.getAttribute("new_htmlrichtext").getValue());
formContext.getAttribute("new_texteditorcontrol").setValue(convertToPlain(formContext.getAttribute("new_htmlrichtext").getValue()));


}

function convertToPlain(html){

    // Create a new div element
    var tempDivElement = document.createElement("div");
    
    // Set the HTML content with the given value
    tempDivElement.innerHTML = html;
    
    // Retrieve the text property of the element 
    return tempDivElement.textContent || tempDivElement.innerText || "";
}

Hope it helps!
