一.添加父窗体JavaScript代码，“showInfo()”方法用于打 开子窗体，并获取子窗体返回结果填充到TextBox1和TextBox2
<script language="javascript" type="text/javascript">
function showInfo()
{
var retValue=window.showModalDialog
('Child.aspx','','scroll=yes;dialogWidth=50;dialogHeight=40');
document.all('<%=TextBox1.ClientID%>').value=retValue[0];
document.all('<%=TextBox2.ClientID%>').value=retValue[1];
}
</script>
二.子窗体服务器端提交数据以数组形式返回到父窗体中，例为 Button1按钮
protected void Button1_Click(object sender, EventArgs e)
{
string scode = "var arr=new Array();arr[0]='aaa';arr[1]='bbb';
window.parent.returnValue=arr;window.parent.close();";
string script = string.Format("<script language='javascript' type='text/javascript'>{0}</script>",scode);
Page.RegisterStartupScript("close",script);
}
