那么，我有这个代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Enter Details</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<form>
<label>Student's Name</label>
<input type="text" placeholder="Enter student's name">
<br><br>
<label>Roll No.</label>
<input type="text" placeholder="Enter student's Roll No.">
<br><br>
<label>Class</label>
<input type="text" placeholder="Enter student's class">
<br><br>
<label>Enter marks for English</label>
<input type="text" placeholder="Marks for English goes here...">
<br><br>
<label>Enter marks for Maths</label>
<input type="text" placeholder="Marks for Maths goes here...">
<br><br>
<label>Enter marks for Science</label>
<input type="text" placeholder="Marks for Science goes here...">
<br><br>
<button>Get your marksheet</button>
</form>
</body>
</html>
假设我给了所有输入一个类或id来标识它们。我做另一个html文件，使表，我希望表的值是相同的输入之一。因此，从技术上讲，我如何在另一个HTML文件中使用一个HTML文件的类和id ?
基本上，当用户提交表单并将其打包到JS对象并将其放入localStorage中时，您希望获得所有输入值。在other.html文件中，检索JS对象并按您想要的方式使用它。
