How can I strip the first 7-8 characters of a text entry off of the response?

You could remove it with JavaScript in the addOnPageSubmit function on the question where you collect it. For example:
Qualtrics.SurveyEngine.addOnPageSubmit(function() {
var input = jQuery("#"+this.questionId+" .InputText");
input.val(input.val().replace(/^https?:\\/\\//i,""));
});

I'll test that out! It would be a great help. Since you made that look so easy, is there a way to replace http:// also? Since they may use either?

That didn't work...possibly because I didn't replace something in your code with a value I was supposed to? Here's what I put in the question's JS section.

Qualtrics.SurveyEngine.addOnload(function()
{
jQuery("#"+this.question+" .InputText").replace(/^https?:\\/\\//i,"");
});

Was I supposed to replace "#" with a value? Or "InputText"?

https://www.qualtrics.com/community/discussion/comment/29544#Comment_29544Sorry, the original code I posted had a mistake. I've corrected it in the original post above. Use as-is (don't change anything) - it works for http:// or https://
Add to the addPageOnSubmit() function - NOT addOnload().

I really appreciate your help...but, there is no "addPageOnSubmit() function. This is what I see. The first three are there by default. I tried adding the fourth...
Qualtrics.SurveyEngine.addOnload(function()
{
});
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*/
});
Qualtrics.SurveyEngine.addOnPageSubmit(function()
var input = jQuery("#"+this.questionId+" .InputText");
input.val(input.val().replace(/^https?:\\/\\//i,""));

I get an invalid token or Var

https://www.qualtrics.com/community/discussion/comment/29547#Comment_29547It is addOnPageSubmit(). I updated the original post above with the whole thing.

TomG I owe you a lunch! Thanks, that did the trick. And for anyone following along, I removed all of the default JS in the Question and replaced it with Tom's code:

Qualtrics.SurveyEngine.addOnPageSubmit(function() {
var input = jQuery("#"+this.questionId+" .InputText");
input.val(input.val().replace(/^https?:\\/\\//i,""));
});
I tested with https://, http://, and finally with neither and it worked like a charm! Thanks again. I'm going to post in another thread where someone was trying to find an answer.
