I use this function to set mine. I add a form variable with a reference to this function. Use a unique class on the rich text field and pass that along with the text you'd like to the function.

function setMyRichTextField(FieldClass, RichText) {
    "use strict";
    NWF$("." + FieldClass).innerhtml(RichText);
}

Hey Jeremiah thanks for your reply.

Here is what I did to reproduce your solution:

• I inserted a Multi Line Textbox with enhanced rich text enabled
• I inserted your function as Custom JavaScript under Form Settings
• I called the function via Form variable like this: setMyRichTextField("MyField", "<p>Test</p>")

When I run it I get the error "Uncaught TypeError: NWF$(...).innerhtml is not a function" and if you search for that error they tell you that you should use" .innerhtml = RichText. This doesn't produce an error but is also not working.

Do you use a normal Rich Text field or a Multi Line Textbox in your solution? 

Thanks

Jan

I am struggling with this. did you find any solution?

Hey Shahad yes we figured it out! 

The accepted solution didn't work for me in Nintex 2016 4.2.1, but I was able to get it working with the code below.

var ntxCtrl = NWF$('#' + ClientIDJavacriptVariable);


NWF$('#' + ntxCtrl.attr("id") + "_inplacerte").html("Test Content Here");

I can confirm this works.
