Question

我想检查jsp页面中选中的单选按钮中的单选按钮值

<% String gen=rs.getString("gender");session.setAttribute("gender",  gen); %>
     <input type="radio" name="gender" id="male"  value="male" />male
     <input type="radio" name="gender" id="female"    value="female" />Female
      <input type="radio" name="gender" id="other"   value="other" />

Answer 1

您可以使用el在条件

上添加checked属性

<input type="radio" name="gender" id="male" value="male" ${gen eq "male"?'checked="checked"':''}/>
<input type="radio" name="gender" id="female" value="female" ${gen eq "female"?'checked="checked"':''}/>Female
<input type="radio" name="gender" id="other" value="other" ${gen eq "other"?'checked="checked"':''}/>

Answer 2

如果此选项的值等于性别，您可以检查每个选项。如果是这样，添加checked =“checked”

例如：

<input type="radio" name="gender" id="male"  value="male" <% Response.Write( (gen == "male") ? ' checked="checked"' : '' ) %> />male
