Answer №1

const updatedURL = previousURL.replace(/&adidiii\=.+[&$]/, "&adidiii=" + encodeURIComponent(**SomeOtherFormField**) + "&")

If you only need to extract a parameter from the URL, use this method:

function extractURLParam(URL, parameter)
{
    const match = URL.match(new RegExp("[\?&]" + parameter + "=([^&]+)"));
    return match[1] ? decodeURIComponent(match[1]) : null;
}
