标签: javascript asp.net sorting gridview

有没有办法使用JavaScript将行添加到gridview?现在我将GridView的onclick方法设置为sortTrGrid(gridviewname),sortTrGrid方法的结构如下所示。我可以按照正确的顺序获取表中的行,但网页上没有任何变化。

    function sortTrGrid(sender) {
        var table = document.getElementById(sender.id);
        var rows = new Array(table.rows);

        for (var i = 0; i < table.rows; i++) {
            rows[i] = table.rows[i];
        }

        for (var i = table.rows; i > 0; i--) {
            table.deleteRow(document.getElementById(i));
            table.rows[i] = rows[i];
        }

    }//end GridSort

假设您的页面包含数据源中的所有行(无分页),并且您希望在客户端上订购GridView行以提高性能(无需访问服务器),您可以执行以下操作:

(此代码允许在单击GridView标题时对数字和文本进行排序并按升序和降序排序)

绑定GridView

<asp:LinqDataSource runat="server" ID="lds" 
    ContextTypeName="WebForms_1.DataAccess.PubsDataContext"
    TableName="jobs"
    EntityTypeName="WebForms_1.DataAccess.jobs">
</asp:LinqDataSource>
<asp:GridView runat="server" ID="gv" DataSourceID="lds" DataKeyNames="job_id">

</asp:GridView>

jQuery代码

<script type="text/javascript">
    $(function () {
        var $gv = $("table[id$=gv]");
        var $headers = $("th", $gv);
        var $rows = $("> tbody > tr:not(:has(table, th))", $gv);

        $rows.addClass("grid-rows");
        $headers.addClass("grid-headers");

        $headers.toggle(function (e) {
            sortGrid($(this), 0);
        }, function (e) {
            sortGrid($(this), 1);
        });

        function sortGrid(row, direction) {
            var colIndex = $(row).parent().children().index($(row));
            var $rowsArray = $.makeArray($rows);
            var $sortedArray = $rowsArray.sort(function (o, n) {
                var $currentCell = $("td:nth-child(" + (colIndex + 1) + ")", $(o));
                var $nextCell = $("td:nth-child(" + (colIndex + 1) + ")", $(n));
                var currentValue = parseFloat($currentCell.text()) ? parseFloat($currentCell.text()) : $currentCell.text();
                var nextValue = parseFloat($nextCell.text()) ? parseFloat($nextCell.text()) : $nextCell.text();

                if (direction == 0) {
                    return currentValue < nextValue ? -1 : 1;
                }
                else {
                    return currentValue > nextValue ? -1 : 1;
                }
            });

            $("> tbody > tr:not(:has(table, th))", $gv).remove();
            $("tbody", $gv).append($sortedArray);
        }
    });
</script>
