这是一个粗略的草图，您需要根据需要对其进行修改。
<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");
var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");
var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");
f.appendChild(i);
f.appendChild(s);
//and some more input elements here
//and dont forget to add a submit button
document.getElementsByTagName('body')[0].appendChild(f);
</script>
