一个范例


【上部分文件：head.aspx】




<s cript runat=server>

void click1 (object a,EventArgs b)

{ label1.Text=text1.Text;

label2.Text=text2.Text;}

</s cript>



<h1> The Softzz 's New page </h1>

<p> 2004-11-15 </p>

Name: <asp:textbox id= "text1 " runat= "server "/>

&nbsp;&nbsp;

Pass: <asp:textbox id= "text2 " runat= "server "

textmode= "password "/>

&nbsp;&nbsp;

<asp:button id= "button1 " runat= "server "

Text= "ClickMe " onClick= "click1 "/>

<HR width= "80% " SIZE= "1 ">




【上部分文件：end.a】




<s cript runat=server>

void click2 (object a,EventArgs b)

{ label1.Text=text3.Text;

label2.Text=text4.Text;

}

</s cript>



<HR width= "80% " SIZE= "1 ">
