Question

我想在下面的示例代码中输入mytable1的Time值，并在mytable2中反映-7小时。考虑到时间范围是00:00 - 23:59也是关键。

<table width=600px id="mytable1">
    <tr>
        <td>GMT</td>
        <td>Monday</td>
        <td>Tuesday</td>
        <td>Wednesday</td>
        <td>Thursday</td>
        <td>Friday</td>
    </tr>
    <tr>
        <td>Person A</td>
        <td>09:00 - 17.30</td>
        <td>17:00 - 01.30</td>
        <td>09:00 - 17.30</td>
        <td>17:00 - 01.30</td>
        <td>09:00 - 17.30</td>
    </tr>
    <tr>
        <td>Person B</td>
        <td>09:00 - 17.30</td>
        <td>17:00 - 01.30</td>
        <td>09:00 - 17.30</td>
        <td>17:00 - 01.30</td>
        <td>09:00 - 17.30</td>
    </tr>
</table>
<br />
<table width=600px id="mytable2">
    <tr>
        <td>GMT-7</td>
        <td>Monday</td>
        <td>Tuesday</td>
        <td>Wednesday</td>
        <td>Thursday</td>
        <td>Friday</td>
    </tr>
    <tr>
        <td>Person A</td>
        <td>09:00 - 17.30</td>
        <td>17:00 - 01.30</td>
        <td>09:00 - 17.30</td>
        <td>17:00 - 01.30</td>
        <td>09:00 - 17.30</td>
    </tr>
    <tr>
        <td>Person B</td>
        <td>09:00 - 17.30</td>
        <td>17:00 - 01.30</td>
        <td>09:00 - 17.30</td>
        <td>17:00 - 01.30</td>
        <td>09:00 - 17.30</td>
    </tr>
</table>
<br />

 var a = document.getElementById(val.id).value-7;
 document.getElementById("to").value=a;alert(a);

<body>
<input type="text" name ="dat" id="fu" onChange="cd(this)"/>
<input type="text" name ="dat" id="to"/>

Possibly this can help you. Substitute all your table values accordingly
