推荐答案

您可以将值发送到表单中的隐藏输入并提交.

You can send value to hidden input in the form and submit it.

function MyReason(){
    var reason = prompt("Reason");
    document.getElementById("reason").value = reason;
    document.getElementById("form").submit();
}

<form id="form">
    <input type="hidden" id="reason" />
</form>
