适用于DataGrid,DataList,Repeater中打勾全部选中的方法

举Repeater为例

 1<asp:repeater id="dlList" Runat="server">
 2<HeaderTemplate>
 3<TR>
 4<td width="26" class="Table_85_grey">
 5<input type="checkbox" id="checkDel" onclick="CheckDelBox(this)" />
 6</td>
 7</TR>
 8</HeaderTemplate>
 9<ItemTemplate>
10<TR>
11<td>
12<asp:CheckBox id="deleteCheckbox" runat="server" AutoPostBack="False"></asp:CheckBox>
13</td>
14</TR>
15</ItemTemplate>
16</asp:repeater>

加javascript

<SCRIPT language="javascript">
        function CheckDelBox(box)    
        {
                for (var i=0;i<document.Form1.elements.length;i++)
            {
                var e = document.Form1.elements[i];
                if ( (e.type=='checkbox') )
                {
                    
                        var o=e.name.lastIndexOf('deleteCheckbox');
                        
                        if(o!=-1)
                        {
                            e.checked = box.checked;
                        }
                
                }
            }
        }
        </SCRIPT>

就OK了
