怎么清除repeater中的删除二个字呢

  <asp:Repeater runat="server" ID="Repeater1" OnItemCommand="Repeater1_ItemCommand"
                                    OnItemDataBound="Repeater1_ItemDataBound">


 <td onclick="displayctrl2('WZXXMC_<%# Eval("sortindex") %>',this);" id="WZXXMC_<%# Eval("sortindex") %>">
                                                <div class="txtlabelClass" id="txtlabel_WZXXMC_<%# Eval("sortindex") %>">
                                                    <asp:Label ID='Grid_Label_WZXXMC' RowIndex='<%# Eval("sortindex") %>' runat="server"
                                                        Text='<%# Bind("WZXXMC") %>&nbsp;'></asp:Label>
                                                </div>




 <td style="text-align: center">
                                                <a href="#" onclick="clearData(<%# Eval("sortindex") %>)">
                                                    <asp:Label ID='label_Delete' Text='删除' runat="server"></asp:Label></a>
                                            </td>
