关于页面取值的问题

JScript code

<%    Calendar cal = Calendar.getInstance();    cal.add(Calendar.DATE, -1);    SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd");    String newTime = sf.format(cal.getTime());%><form id="taizhytk" name="taizhytk" method="post" class="checkout" action=""><div>        <table>            <tr>                <td>                    查询时间：                    <input id="begintime" name="begintime" type="text" onclick="WebCalendar.start(this, 'yyyy-MM-dd')"                           value="<%=newTime %>" maxlength="20" style="width:80px" readonly/>                    <input type="button" name="to_select" id="to_select" value="查  询"/>                </td>            </tr>        </table>    </div>    <div>        <tr>            <th nowrap="nowrap" colspan="7" width="90%" background="<c:url value="/images/head.gif"/>">                <font color="bule" style="font-size: 13pt" >[color=#FF0000]日期[/color]                </font></th>        </tr>    </div><form>

我想在红色的日期处显示上面bdgintime的值.怎么处理呢,

[解决办法]

JScript code

<script type="text/javascript">function setDateValue(){var dateHtml = '[color=#FF0000]'+ document.getElementById('begintime').value+'[/color]';document.getElementByTagName('font').get(0).innerHtml = dateHtml;}<input type="button" name="to_select" id="to_select" value="查 询" onclick="setDateValue();" />
