<%if%><%else%>问题..
小弟我对下面的代码有点问题,为什么 <%if%> <%else%> 语句可以控制 <%%> 外面的空间是否显示啊.哪位高人给讲讲解下原理是怎么回事?小弟一直认为 <%%> 里面的东西对外面的代码没影响.向大虾们学习了。.
<%if(true)%>
<%{%>
<asp:TextBox   id= "Textbox2 "   style= "Z-INDEX:   101;   LEFT:   240px;   POSITION:   absolute;   TOP:   88px "   runat= "server "> </asp:TextBox>
<asp:Button   id= "Button2 "   style= "Z-INDEX:   102;   LEFT:   256px;   POSITION:   absolute;   TOP:   128px "   runat= "server "   Text= "Button "> </asp:Button>
<SELECT   style= "Z-INDEX:   103;   LEFT:   272px;   WIDTH:   176px;   POSITION:   absolute;   TOP:   184px ">
<OPTION   selected> </OPTION>
</SELECT>
<%}%>
<%else%>
<%{%>
<asp:TextBox   id= "Textbox3 "   style= "Z-INDEX:   101;   LEFT:   240px;   POSITION:   absolute;   TOP:   88px "   runat= "server "> </asp:TextBox>
<SELECT   style= "Z-INDEX:   103;   LEFT:   272px;   WIDTH:   176px;   POSITION:   absolute;   TOP:   184px ">
<OPTION   selected> </OPTION>
</SELECT>
<%}%>

不要被表面现象蒙蔽，
经编译器解析后，会将页面所有的 <% %> 内有连编成一体
