我希望仅使用JavaScript将表单数据显示到新标签页。这不是我的任务。怎么做到这一点？
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<script language="JavaScript">
function showInput() {
var message_entered = document.getElementById("user_input").value;
document.getElementById('display').innerHTML = message_entered;
}
</script>
</head>
<body>
<form>
<label><b>Enter a Message</b></label>
<input type="text" name="message" id="user_input">
</form>
<input type="submit" onclick="showInput();"><br />
<label>Your input: </label>
<p><span id='display'></span> </p>
</body>
</html>
