<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');
    }

这

不起作用，因为我错过了之后的开头和右侧大括号

（var j = 0; j

<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)

    }
