Question

我有一个jsp页面，我放置了几个单选按钮。

选择单选按钮并单击提交按钮后，它将调用一个javascript函数，该函数需要单选按钮的选定值才能对scriplet执行某些操作。

任何人都可以解决这个问题吗？

<td align="center"><input type="radio" name="radio" id="radio" value="value1"></td>
<td align="center"><input type="radio" name="radio" id="radio" value="value2"></td>
<td align="center"><input type="radio" name="radio" id="radio" value="value3"></td>

<td ><a onclick="Javascript:delete();"><span>Delete</span></a></td>

<script language="javascript" type="text/javascript">
function delete()
{
    <% String str= here i want that selected radio buttons value%>
}
</script>

<script language="javascript" type="text/javascript">
        function deleteme() {
            var values = document.getElementsByName('radio');

            for ( var i = 0, length = values.length; i < length; i++) {
                if (values[i].checked) {
                    // do whatever you want with the checked radio
                    alert(values[i].value);
                    // only one radio can be logically checked, don't check the rest
                    break;
                }
            }
        }
    </script>

    <td align="center"><input type="radio" name="radio" id="radio" value="value1">value1</td>
    <td align="center"><input type="radio" name="radio" id="radio" value="value2">value2</td>
    <td align="center"><input type="radio" name="radio" id="radio" value="value3">value3</td>

    <td><a onclick="deleteme();">Delete</a></td>

单击按钮后，我可以在scriptlet中获取所选单选按钮的值
