&nbsp;</I><BR>∶<I>&nbsp;我的做法：

&nbsp;<BR>谢谢!看到你的文章之前,根据soybean网友的提示(见3776)
&nbsp;<BR>我刚刚用另外一种方法达到目的(利用Javascript):
&nbsp;<BR>
&nbsp;<BR>&lt;script&nbsp;language=&quot;JavaScript&quot;&gt;
&nbsp;<BR>&lt;!--&nbsp;填写用户名进入聊天室
&nbsp;<BR>function&nbsp;GotoChat(UserName)
&nbsp;<BR>{
&nbsp;<BR>&nbsp;document.write('&lt;p&nbsp;align=&quot;center&quot;&gt;&lt;font&nbsp;color=&quot;#0000FF&quot;&nbsp;size=&quot;5&quot;&gt;&lt;strong&gt;东南&nbsp;<BR>大学办公BBS站-聊天室&lt;/strong&gt;&lt;/font&gt;&lt;/p&gt;');
&nbsp;<BR>&nbsp;document.write('&lt;center&gt;&lt;applet&nbsp;CODEBASE=&quot;chat/&quot;&nbsp;CODE=&quot;ChatClient.class&quot;&nbsp;&nbsp;<BR>NAME=&quot;Chat&quot;&nbsp;WIDTH=&quot;400&quot;&nbsp;HEIGHT=&quot;300&quot;&nbsp;HSPACE=&quot;0&quot;&nbsp;VSPACE=&quot;0&quot;&nbsp;ALIGN=&quot;middle&quot;&gt;');
&nbsp;<BR>&nbsp;<BR>&nbsp;document.write('&lt;param&nbsp;name=&quot;Host&quot;&nbsp;value=202.119.11.179&gt;');
&nbsp;<BR>&nbsp;document.write('&lt;param&nbsp;name=&quot;Port&quot;&nbsp;value=7218&quot;&gt;');
&nbsp;<BR>&nbsp;document.write('&lt;param&nbsp;name=&quot;UserName&quot;&nbsp;value='+UserName+'&gt;&lt;/applet&gt;&lt;/center&gt;'&nbsp;<BR>);
&nbsp;<BR>&nbsp;&nbsp;document.write('&lt;p&nbsp;align=&quot;center&quot;&gt;&lt;a&nbsp;href=&quot;bbsmain.htm&quot;&gt;&lt;img&nbsp;&nbsp;<BR>src=&quot;images/sonic.gif&quot;&nbsp;&nbsp;alt=&quot;返回主选单&quot;&nbsp;border=&quot;0&quot;&nbsp;width=&quot;42&quot;&nbsp;height=&quot;42&quot;&gt;返&nbsp;<BR>回主选单&lt;/a&gt;&lt;/p&gt;');
&nbsp;<BR>}
&nbsp;<BR>//&nbsp;--&nbsp;结束JavaScript&nbsp;--&gt;
&nbsp;<BR>&lt;/script&gt;
&nbsp;<BR>
&nbsp;<BR>
&nbsp;<BR>&lt;form&nbsp;method=&quot;POST&quot;&nbsp;name=&quot;FormGetName&quot;&gt;
&nbsp;<BR>&nbsp;&nbsp;&lt;div&nbsp;align=&quot;center&quot;&gt;&lt;center&gt;&lt;p&gt;&lt;font&nbsp;color=&quot;#FF00FF&quot;&gt;&lt;strong&gt;您的聊天代号：&nbsp;<BR>&lt;/strong&gt;&lt;/font&gt;&lt;input
&nbsp;<BR>&nbsp;&nbsp;type=&quot;text&quot;&nbsp;name=&quot;Name&quot;&nbsp;size=&quot;20&quot;&gt;&lt;/p&gt;

&nbsp;<BR>&nbsp;&nbsp;value=&quot;清除&quot;&nbsp;name=&quot;B2&quot;&gt;&lt;/p&gt;
