tabel 选中行变色和取当前选中行值等问题

　　先把代码贴出来

　　　　

　　$("#tableId tbody tr").mousedown(function () {
        $('#tableId  tr').each(function () {
            $(this).css("background-color", "");
        });
        $(this).css("background-color", "#98D8F5");
    });

    //详细页面按钮
    $("#Detail_Button").click(function () {
        var baseinfoMngno = "";
        $('#tableId tr').each(function () {
            if ($(this).css("background-color") != $("th").css("background-color")) {
                baseinfoMngno = $(this).find("td").eq(0).text();
                return false;
            }
        });
        if (baseinfoMngno == null || baseinfoMngno == undefined || baseinfoMngno == "") {
            alert("请选择一样数据");
        } else {
            window.location.href = "ContentsMngTblOperate.aspx?type='detail'&baseinfoMngno=" + baseinfoMngno;
        }
    })

　　<table ).ToString()%></td>
                            </tr>
                            </ItemTemplate>
                        </asp:Repeater>
                    </tbody>
                </table>

　　上面这段代码应该很容易理解吧
