Permitting only letters, no spaces, in a text field | XM Community
Skip to main content

Hi all,
I've been trying everything I can to make this work and can't figure it out. I'm trying to correct the trailing space that iPhones create when responders autocomplete a text field. (e.g. I want "ABCD" not "ABCD ")
The solution that looks most promising is to use custom validation for the field and I thought I had it correct with "^[A-Za-z]$" but unfortunately, that won't permit anything to be accepted. Can you point out what I'm doing wrong?
Thanks for any and all help,
JMag

However, this will only confuse your respondents, as they won't be able to see the trailing space. This JS should do it for you:
Qualtrics.SurveyEngine.addOnReady(function () {
    let prolems_created_by_apple = this.questionContainer.querySelectorAll(".InputText");
    document.querySelector("#NextButton").onclick = function () {
        prolems_created_by_apple.forEach((bad_thing_done_by_iphone) => {
            bad_thing_done_by_iphone.value = bad_thing_done_by_iphone.value.trim();
        });
    };
});
