我想创建一个HTML申请表，并通过电子邮件发送给申请人。每个人都必须下载文件，单独填写并发送给我。
是否可以嵌入保存按钮并永久覆盖更改？我所能找到的只是将更改保存在本地(或作为一个单独的文件(，这不是我想要的。这里有一个我可以在w3schools上找到的简单表格：
<form action="/action_page.php">
<label for="fname">First name:</label><br>
<input type="text" id="fname" name="fname" value="John"><br>
<label for="lname">Last name:</label><br>
<input type="text" id="lname" name="lname" value="Doe"><br><br>
<input type="submit" value="Save">
</form>
我找到了这段代码。我所要做的就是将输出更改为html，并按照我想要的方式进行样式设置。虽然它将更改保存为一个新文件，但没关系。我找不到其他任何东西：
<!DOCTYPE html>
<html>
<head>
<title>Save form Data in a Text File using JavaScript</title>
<style>

box-sizing: border-box;
}
div {
padding: 10px;
