关于forms里的Checkbox全选个人总结

今天早上写了个小程序

是要将DataList里面的CheckBoxList全选

 

不多说了，代码如下

 

 

                        <table border="1">
                            <TBODY>
                                <tr>
                                    <td><asp:CheckBox ID="AllContentCheck" Text="全选" Runat="server" onclick="checkClick();"></asp:CheckBox></td>
                                    <td>标题</td>
                                    <td>详细内容</td>
                                </tr>
                                <asp:repeater id="RepeaterBankInfo" Runat="server">
                                    <ItemTemplate>
                                        <tr>
                                            <td>
                                                <asp:CheckBox ID="BookContentCheck" Runat="server"></asp:CheckBox></td>
                                            <td>
                                                <asp:Label ID="lbTitle" Runat="server"></asp:Label></td>
                                            <td>
                                                <asp:Label ID="lbContent" Runat="server"></asp:Label></td>
                                        </tr>
                                    </ItemTemplate>
                                </asp:repeater></TBODY></table>
                    </td>

 

 

全选的Js代码如下

 

            function checkClick()
            {
                var RowCnt=<%=rowsCount%>;
                var IsChk;
                IsChk = document.all.AllContentCheck.checked;
                var i;  
                elem=window.Form1.elements;
                for(i=0;i<elem.length;i++){
                          
                    if (document.Form1.elements[i].type=="checkbox"){
                        document.Form1.elements[i].checked=IsChk;     
                }

                }
            }
        </script>
