asp.net 的框架问题 使多个页面在同一个页面中显示

框架页

<iframe src="left.aspx" scrolling="no" name="left" style=" height: 900px; width:150px;" ></iframe>

  <iframe src="newsList.aspx" scrolling="yes" name="main"  style="height: 900px; width:550px" id="IFRAME1" onclick="return IFRAME1_onclick()" ></iframe>

 

 

 

left页面代码

        <table style="height: 100px">
            <tr>
                <td style="width: 100px; height: 12px; text-align: center; background-color: #ccccff;">
                 
                <a href="newsList.aspx" target="main" > 信息修改</a>&nbsp;<br />
                   
                    <br />
                  <a href="alterpwd.aspx" target="main" ></a>  
                    <br />
                </td>
            </tr>
            <tr>
                <td style="width: 100px; height: 23px; text-align: center; background-color: #ccccff;">
                    <span style="color: #0000ff; text-decoration: underline"> <a href="addNews.aspx" target="main" >添加信息</a><br />
                        <br />
                    </span>
                    <br />
                </td>
            </tr>
            <tr>
               <td style="width: 100px; height: 23px; text-align: center; background-color: #ccccff;">
                    <span style="color: #0000ff; text-decoration: underline; background-color: #ccccff;"> <a href="alterpwd.aspx" target="main" >修改密码</a><br />
                        <br />
                        <br />
                    </span></td>
            </tr>
           
        </table>

本例中main是重点，当然可以换成其他的名称，
