<tr><th height="150">时间th>
<td><input type="text" name="shijian" id="datetime">td>tr>

<div id="datetime">
    <script>
        setInterval("document.getElementById('datetime').innerHTML=new Date().toLocaleString();", 1000);
    script>
div>


<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title></title>
    <link rel="stylesheet" href="">
</head>
<body>
    <tr><th height="150">时间</th>
<td><input type="text" name="shijian" id="datetime"></td></tr>
 
<div id="datetime">
    <script>
        setInterval("document.getElementById('datetime').value=new Date().toLocaleString();", 1000);
    </script>
</div>
</body>
</html>

获取 input 然后给 value设置 一下

<script>
    setInterval("document.getElementById('datetime').value=new Date().toLocaleString();", 1000);
</script>



<tr><th height="150">时间</th>
<td><input type="text" name="shijian" id="datetime"></td></tr>
 
<div>
    <script>
        setInterval("document.getElementById('datetime').innerHTML=new Date().toLocaleString();", 1000);
    </script>
</div>
