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
<html xmlns="http://www.w3.org/1999/xhtml" >
<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：
<html xmlns="http://www.w3.org/1999/xhtml" >
<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。
