在页面刷新时保留单选按钮选择 [英] Retain Radio Button selection on page refresh

问题描述

我有一个包含2个选项的下拉列表。从下拉列表中选择第一个选项我显示一个DIV，它有两个类别供用户回答。这些是要选择的单选按钮。

但是从下拉列表中选择第二个选项后，DIV区域被隐藏。

再次，我从下拉列表中选择第一个选项。

这样做我从选择默认值时单选按钮中丢失了用户选择的值。如何将其保留给用户选择？我正在使用已检查属性。

仍然无效。

以下是代码段。

Hi,
I have a a dropdown list with 2 options. Selecting first option from dropdown I display a DIV which has two categories for user to answer.These are radio buttons to be selected.
However after selecting second option from the drop down list,the DIV area is hidden.
Again I select the first option from the drop down list.
Doing this I am losing the user selected values from radio buttons as they get selected to default. How can I retain them to user selected? I am using the "checked" attribute.
Still doesn't work.
Following is the code snippet.

<TABLE id="Mytable"><TBODY>
<TR>
<TD>
<INPUT type=radio id="firstone" name="first" onclick="" VALUE="1" <%=("1".equals(Mytable)?"CHECKED":"")%>></TD>
<INPUT type=radio id="secondone" name="second" onclick="" VALUE="2" <%=("2".equals(Mytable)?"CHECKED":"")%>></TD>
</TR>
</TBODY>
</TABLE>
