Javascript 检查gridview上的所有单选列表单选按钮是否已选中

我已经设计了一个表单的审查，同时保存此表单，我必须检查是否所有单选列表单选按钮已被选中，我也写了javascript，但它没有给欲望的输出，所以请帮助我

<script type="text/javascript">
    var validateradios = function () {

        var icount = 0;
        var grid = document.getElementById('<%=gvQuestion.ClientID %>');
        alert(grid.rows.length);
        for (var i = 1; i < grid.rows.length; i++) {
            var row = grid.rows[i];
            var targetcell = row.cells[2];
            var inputs = targetcell.getElementsByTagName("input");
            alert(inputs.length);
            for (var j = 0; j < inputs.length; j++)

                if (inputs[0].checked) {
                    icount++; break;
                }


        }

        if (icount == (grid.rows.length - 1))
            alert(' all rows checked');
        else
            alert('some rows need to be checked');

    }
</script>

var validateradios=函数（）{
var-icount=0；
var grid=document.getElementById（“”）；
警报（网格、行、长度）；
对于（var i=1；i

这不起作用，因为我错过了打开和关闭花括号的时间

（var j=0；j

var validateradios=函数（）{
var-icount=0；
var grid=document.getElementById（“”）；
警报（网格、行、长度）；
对于（var i=1；i

您反对为此使用服务器端代码吗？

<script type="text/javascript">
    var validateradios = function () {
        var icount = 0;
        var grid = document.getElementById('<%=gvQuestion.ClientID %>');
        alert(grid.rows.length);
        for (var i = 1; i < grid.rows.length; i++) {
            var row = grid.rows[i];
            var targetcell = row.cells[2];
            var inputs = targetcell.getElementsByTagName("input");
            for (var j = 0; j < inputs.length; j++) {
                if (inputs[j].checked) {
                    icount++; break;  
                }
            }
        }
        alert(icount)
        if (icount == (grid.rows.length - 1))
            alert(' all rows checked');
        else
            alert('some rows need to be checked');
    }
</script>
