这章内容比较简单,直接上页面代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Recipe6.aspx.cs" Inherits="Recipe6" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Recipe6</title> <script src="Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { $("#<%=chkSelectAll.ClientID %>").click(function () { // 很简单,一行代码搞定 $("#<%=chkList.ClientID %> input[type=checkbox]").attr("checked", $("#<%=chkSelectAll.ClientID %>").is(":checked")); }); }); </script> </head> <body> <form id="form1" runat="server"> <div align="left"> <p> 实现全选或全取消操作</p> <fieldset style="width: 400px; height: 150px;"> <asp:CheckBox ID="chkSelectAll" runat="server" Text="全选" /> <hr /> <asp:CheckBoxList ID="chkList" runat="server"> <asp:ListItem Value="1" Text="C#"></asp:ListItem> <asp:ListItem Value="2" Text="Java"></asp:ListItem> <asp:ListItem Value="3" Text="C++"></asp:ListItem> <asp:ListItem Value="4" Text="JavaScript"></asp:ListItem> </asp:CheckBoxList> </fieldset> </div> </form> </body> </html>
