Answer 1

尝试使用以下内容并将其添加到 html 标记末尾之前。

<script>
var myForm = document.createElement("form");
myForm .setAttribute('method',"post");
myForm .setAttribute('action',"submit.php");

var myInput = document.createElement("input"); 
myInput .setAttribute('type',"file");
myInput .setAttribute('name',"somename");

var formSubmit = document.createElement("input"); 
formSubmit.setAttribute('type',"submit");
formSubmit.setAttribute('value',"Submit");

myForm .appendChild(myInput);
myForm .appendChild(formSubmit);

document.getElementsByTagName('body')[0].appendChild(myForm);

</script>
