Hi Thomas,

It's not perfect (as it doesn't stop non-js resubmits) but how about a bit of javascript..:

change contourformContactForm to match the id of your form (use the browser inspector tools if you're not sure). Add a class to your css for .disabled to grey out the button.

$(document).ready(function () {

    var formSubmitted = false;

    $('#contour_form_ContactForm').submit(function (event) {
        $('#contour_form_ContactForm input').addClass("disabled");
        if (formSubmitted) {
            event.preventDefault ? event.preventDefault() : event.returnValue = false
            console.log("no double submits");
        }
        formSubmitted = true; // stop double submits
    });
});

Hi Thomas,
I needed to resolve the same problem with multiple Contour form submissions and achieved good results with the solution provide by Steve Morgan.
Ultimately, I found adjusting the properties of the submit button directly worked well.
$('input[type="submit"]').prop('disabled', true); $('input[type="submit"]').prop('value', 'Processing');

is working on a reply...
