First, replace the original code with all the following code:
<Table id = "tbList"> <tr> <td>
<Asp: DataList ID = "DataList1" runat = "server" Width = "100%"
>
<HeaderTemplate>
<Table style = "width: 100%; font-size: 10pt;" border = "0" cellpadding = "0" cellspacing = "0">
<Tr>
<Td class = "two_out_three_net1" align = "center">
<Input id = "cbxItemAll" runat = "server" name = "chkAll" onclick = "IsorNotAll (this);" type = "checkbox"/>
</Td>
<Td class = "two_out_three_net2" align = "center"> title </td>
<Td class = "two_out_three_net3" align = "center"> clicks </td>
<Td class = "two_out_three_net4" align = "center"> attributes </td>
<Td class = "two_out_three_net5" align = "center"> Status </td>
</Tr>
</Table>
</HeaderTemplate>
<ItemTemplate>
<Table style = "width: 100%; font-size: 10pt; & ...... the remaining full text>
Check whether all or not to select a checkbox
The figure is not clear, but the general principle is as follows:
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312"/>
<Title> untitled document </title>
<Script language = "javascript">
Function selected ()
{
Var allsel = document. getElementsByName ("car ");
For (var I = 0; I <allsel. length; I ++)
{
Allsel [I]. checked =! Allsel [I]. checked;
}
}
</Script>
</Head>
<Body>
<H1> select all/do not select all Select All/cancel <br/>
<Input type = "checkbox" id = "sel" name = "sel" value = "yes" onclick = "selected ()">
<Br/>
<Input type = "checkbox" id = "car" name = "car" value = "two"> aa <br/>
<Input type = "checkbox" id = "car" name = "car" value = "three"> bb <br/>
<Input type = "checkbox" id = "car" name = "car" value = "four"> cc <br/>
</Body>
