Block Copy Paste in a text entry box

For this I guess you are using text entry form type question with two fields.
Paste the below code in the JS of this question:
jQuery("#"+this.questionId+" .InputText:eq(1)").on("cut copy paste",function(e) {
   e.preventDefault();
  });

Thanks. I must be doing something wrong. I know nothing about Java Script. This is what I see when I go to the JS portion for the field. Do I replace the entire thing with your line of code? Or?

Qualtrics.SurveyEngine.addOnload(function()
{
 /*Place your JavaScript here to run when the page loads*/
});
Qualtrics.SurveyEngine.addOnReady(function()
{
 /*Place your JavaScript here to run when the page is fully displayed*/
});
Qualtrics.SurveyEngine.addOnUnload(function()
{
 /*Place your JavaScript here to run when the page is unloaded*/
});

It will be under onReady function as shown below:

This is what I have. Upon testing in preview mode and through a link, I can still copy/paste. I tried putting it in the JS for each of the two questions thinking that might work, but it didn't.

Which question type are you using?

The custom validation is Matches RegEx to make it so that the user can only enter seven numerical digits.

Works perfectly. Thanks
