value = ""问题
<input   type   = "text "   name   =   "textname "   value   =   " "> <br>

里面value   =   " "里面放变量是什么格式的呢?

String   str   =   " "


比如   value   =   "+str "         可以吗?

------解决方案--------------------
<%
String str = "12312 ";
%>

<input type = "text " name = "textname " value = <%=str%> > <br>

一个是jsp
1个是html
