ADF: Partially restricting user entry in the ADF input text - using Java Script

Here is an example. Let us assume the input text contains the following text. "You can edit the content inside { this }". In this, users should be able to edit only the content inside { }. I.e Only "this" should be editable.

To achieve this, we can use a java script method, that tracks the cursor position and ignore the user edits if the cursor position is not between the curly braces. After which, the method would be used in the client listener for the input text.
