摘要:JavaScript实现弹出子窗口并传值给父窗口
新建父窗口页面: 加入以下脚本
[url=http://www.w3.org/1999/xhtml]http://www.w3.org/1999/xhtml[/url]" > <head runat="server">     <title>First</title> </head> <script type="text/javascript"> function ShowDialog(Url) {       var  iWidth=560; //模态窗口宽度       var  iHeight=300;//模态窗口高度       var  iTop=(window.screen.height-iHeight-100)/2;       var  iLeft=(window.screen.width-iWidth)/2;       var returnValue=window.showModalDialog(Url, "newwindow", "dialogHeight:"+iHeight+"px; dialogWidth:"+iWidth+"px; toolbar:no; menubar:no; scrollbars:no; resizable:no; location:no; status:no;left:200px;top:100px;");       document.getElementById("TextBox1").innerText=returnValue; } </script> <body>     <form id="form1" runat="server">          <input id="Button1" type="button" value="button" onclick="ShowDialog('./second.aspx')" />          <div><asp:TextBox ID="TextBox1" runat="server" Width="67px"></asp:TextBox></div>      </form> </body> </html>
创建second.html页面:
[url=http://www.w3.org/1999/xhtml]http://www.w3.org/1999/xhtml[/url]" > <head runat="server">     <title>second</title>     <!--<base target="_self" ></base>--> </head> <script language="javascript">     function closeDiag()     {         window.opener=null;         window.close();     }      function OK()     {         var Value=document.getElementsByName("myRadio");         for(var i=0;i<Value.length;i++)         {             if(Value[i].checked)             {                  window.returnValue = Value[i].value;                 window.close();             }             else             {                 document.getElementById("Lab_Info").innerText="没有选中项,请选择!";             }         }          }  </script> <body>     <form id="form1" runat="server">     <div>           <asp:DataGrid ID="dgSjygl" runat="server" AllowPaging="True" AutoGenerateColumns="False"                         BackColor="White" Font-Size="9pt" PageSize="5" Width="100%" Height="127px" OnItemDataBound="dgSjygl_ItemDataBound">                         <PagerStyle Mode="NumericPages" />                         <AlternatingItemStyle BackColor="Gainsboro" />                         <ItemStyle BackColor="#EEEEEE" ForeColor="Black" HorizontalAlign="Center" />                         <Columns>                             <asp:TemplateColumn>                                             <HeaderTemplate>                                     <label>选择</label>                                 </HeaderTemplate>                                 <ItemTemplate>                                                                        <input type="radio" id="myRadio" name="myRadio"  value='<%# DataBinder.Eval(Container.DataItem, "id") %>'>                                 </ItemTemplate>                                 <HeaderStyle Font-Bold="True" HorizontalAlign="Center" Width="60px" />                                 <ItemStyle HorizontalAlign="Center" />                             </asp:TemplateColumn>                             <asp:BoundColumn DataField="ID" HeaderText="编号">                                 <HeaderStyle Font-Bold="True"  Width="75px" HorizontalAlign="Center"/>                             </asp:BoundColumn>                             <asp:BoundColumn DataField="MC" HeaderText="名称">                                 <HeaderStyle Font-Bold="True"  Width="90px" HorizontalAlign="Center"/>                                 <ItemStyle HorizontalAlign="Center" />                             </asp:BoundColumn>                             <asp:BoundColumn DataField="BT" HeaderText="标题">                                 <HeaderStyle Font-Bold="True" HorizontalAlign="Center"/>                             </asp:BoundColumn>                         </Columns>                         <HeaderStyle BackColor="#7481BA" ForeColor="Yellow" Font-Bold="False" Font-Italic="False" Font-Overline="False" Font-Strikeout="False" Font-Underline="False" Font-Size="Small" />                     </asp:DataGrid>     </div>     <div>           <input id="Btn_OK" type="button" onclick="OK()" value="确 定"/>           <input id="Btn_Cancel" type="button" onclick="clickDiag()"  value="取 消" />      </div>            </form> </body> </html>
以上就是本人实现这个简单功能的全部内容了,感觉应该还有更便捷的方法,有知道的小伙伴还请留言说明下。
