Lock a specific Text Field


Not applicable

I have a Text Field which gets populated with random numbers every time the form is opened.

I would like to add a button using JavaScript which will lock only that Text Field when clicked after form was rendered so that the number remain static when opening and closing the form.

I'm sure you could modify this for your purposes, but here's my solution with a checkbox instead of a button.


So, if that box is checked when the form is saved, the text field will not generate a random number when the form is opened again.


Not applicable

Add the following script on the initialize event of the textfield that should get locked.

if(this.rawValue !=  nul)

     this.access = "protected";

the previous script contains a typo and won't work.

Try this script instead.

this.access = this.isNull ? "open" : "protected";
