Contact form, disable submit button after clicked

I downloaded a working contact form and added a few things that I needed, but now I have another problem that I do not know how to fix it.

After form is submitted, the button can still be clicked a few times and that will send more than one email to me. After form is submitted, it should disable the button.

HTML:

<button type="submit" id="form-submit" class="btn btn-success btn-lg pull-right ">Submit</button>
<div id="msgSubmit" class="h3 text-center hidden"></div>
<div class="clearfix"></div>

And here is the JavaScript code:

$("#contactForm").validator().on("submit", function (event) {
    if (event.isDefaultPrevented()) {
        // handle the invalid form...
        formError();
        submitMSG(false, "Did you fill in the form properly?");
    } else {
        // everything looks good!
        event.preventDefault();
        submitForm();
    }
});

const $contactForm=document.getElementById("contactForm");
const $submitButton=$contactForm.getElementById("form-submit");
$contactForm.addEventListener("submit",e => {
e.preventDefault();
$submitButton.setAttribute("disabled","disabled") }) //first is attribute, second is value, disabled

Javascript is simple, keep it simple.

Multiple things can be done here depending on your complete architecture. You can use jQuery's one function, although I don't recommend it, because this will mean that until you load the page the contact form can be submitted only once.

What I do is, that I would disable the button, $("#form-submit").attr("disabled","disabled"); OR $("#form-submit").addClass("inactive") and in your CSS use

#form-submit{
    pointer-events:none;
    opacity:0.6;
    /*etc etc*/
}

and when your ajax returns just do the opposite(remove the disabled attribute or class). Also, set the input, textarea values to empty string.

Disable the button on form submit, like this:

$("#contactForm").validator().on("submit", function (event) {
    if (event.isDefaultPrevented()) {
        // handle the invalid form...
        formError();
        submitMSG(false, "Did you fill in the form properly?");
    } else {
        // everything looks good!
        event.preventDefault();
        $("#form-submit").prop("disabled",true);
        submitForm();
    }
});
