Fillable PDF to Read Only, back to Fillable

[PDFNewbieCanada]

Hi Everyone, 

I am relatively new to PDF javascript and I am trying to make a PDF where you can fill it out, click a submit button which will convert it to a Read-Only before sending, but the will convert it back to the original fillable formate once the submission is completed. 

I have the javascript to convert the form into a REad-Only, but I am wondering if there is an additional javascript I can add to the following which will convert it back to the original fillable form. 

Read-Only Conversion:

for (var i = 0; i < this.numFields; i++)
{
this.getField(getNthFieldName(i)).readonly=true;
}

Just reverse the boolean state:

for (var i = 0; i < this.numFields; i++) {this.getField(getNthFieldName(i)).readonly=false;}

I don't know what it is, but my brain was not thinking that I could just reverse the coding. 
Thank you so much, JR.

Boolean properties can only have two states: true/false (or 1/0).
