刷新页面后单选按钮可以为空吗

Question

我的表单中有两个单选按钮。现在我发现，在某些浏览器（firefox 和 google chrome）中，如果您刷新表单，在刷新之前选择了单选按钮，然后在刷新后仍选择单选按钮。我想知道有没有办法通过使用 javascript 代码来说明当页面重新加载或刷新时不应该选择单选按钮，或者这一切都取决于浏览器？

以下是javascript中单选按钮的代码：

    var btnRadioO = document.getElementsByName("weightChoice");               
                    var isbtnRadioChecked = false;

      for(i=0; i < btnRadioO.length; i++){
                        if(btnRadioO[i].checked){
                            isbtnRadioChecked = true;
                        }
                    }

                    if(!isbtnRadioChecked) {
                       errRadioMsgO.innerHTML = "Please Select whether you want to include a Total Weight for your Session or Not";
                    tblWeightO.style.display = "none";
                       isDataValid = false;
                    }else if(btnRadioO[0].checked==true && weightO.value == 0){
                         errRadioMsgO.innerHTML = "";
                         errWeightMsgO.innerHTML = "You are including Weight so it Must be More Than 0";
                         isDataValid = false;
                         }else if(btnRadioO[1].checked==true){
                    errRadioMsgO.innerHTML = "";
                     errWeightMsgO.innerHTML = "";
                    tblWeightO.style.display = "none";
                         }else{
                             errRadioMsgO.innerHTML = "";


  errWeightMsgO.innerHTML = "";
                     }

HTML代码：

<table>
            <tr>
            <th>6: Provide a Total Weight for your Session</th>
            <td><input type="radio" name="weightChoice" value="yes" onClick="getWeight()"/> Yes</td>
            <td><input type="radio" name="weightChoice" value="No" onClick="getWeight()"/> No</td>
            </tr>
            </table>

可能是浏览器缓存页面。尝试在两个单选按钮上设置checked=false 开始。如果这不起作用，请查看页面缓存选项。
