一，从子窗口传值到父窗口

父窗口html

{
        var ret=window.showModalDialog("IssueApp.aspx");//ret传回的值
        if(ret=='undefined')
        {
            return ;
        }
        if(ret=='')
        {
            return ;
        }
        if(ret==null)
        {
            return ;
        }
       //ret=ikeli3,李科威
        var a=ret.substring(0, ret.indexOf(",", 0));
        var b=ret.substring(ret.indexOf(",", 0) 1);

        document.getElementById(t).value =a  //txtApp1.text=a
        document.getElementById(t1).value =b //txtEngName.text=b
}
</Script>

父窗口调用，控件一定是HTML控件

<input ID="btnApp1" type="Button" value=" showModalDialog使用总结_sed

." language="javascript" onclick="btnApp1_onclick('txtApp1','txtEngName1')" />

父窗口web里面取控件的值

Dim strApp1 As String = Request("txtApp1").Trim '需要设置HTML 控件name="txtApp1"
Dim strEngName1 As String = Request("txtEngName1").Trim

子窗口（跳出的窗口）html回传值

<head runat="server">
    <title>Untitled Page</title>
    <base target="_self"></base>    //这个很有用，刷新后还保持原来的页面大小
    <script type="text/javascript" language="javascript">

      function DbClickEvent(d)
        {
            var ret="";
          //window.alert("事件类型: DoubleClidk  作用对象: " d);
            ret=d;
            returnValue=ret;
            window.close();
        }
    </script>
</head>

子窗口web里面赋值

'通过点击GridView行取得赋值数据
Protected Sub gdvQemployee_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gdvQemployee.RowDataBound
        '首先判断是否是数据行
        If e.Row.RowType = DataControlRowType.DataRow Then
            '当鼠标停留时更改背景色
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'")
            '当鼠标移开时还原背景色
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'")
            Dim str1 As String = e.Row.Cells(1).Text
            Dim str2 As String = e.Row.Cells(0).Text
            Dim str3 As String = "" & str1 & "," & str2 & ""
            e.Row.Attributes.Add("OnDblClick", "DbClickEvent('" & str3 & "')")  '双击行触发事件
        End If
    End Sub

二.从父窗口传值到子窗口

父窗口html，变量传值

Code
<script type="text/javascript" language=javascript>
function ShowWindow(SNO)
{
var ret=window.showModalDialog("PEJudge.aspx?SNO="+SNO,"","dialogHeight: 700px; dialogWidth: 680px; dialogTop: 200px; dialogLeft: 100px; edge: Raised; center: Yes; help: Yes; resizable: Yes; status: Yes;")
}
</script>

传两个参数的。

'传两个参数
<script type="text/javascript" language="javascript">
function ShowWindow(SNO,PN)
{
var sret=window.showModalDialog("QAJudge.aspx?SNO="+SNO+"&PN="+PN,"","dialogHeight: 560px; dialogWidth: 680px; dialogTop: 130px; dialogLeft: 100px; edge: Raised; center: Yes; help: Yes; resizable: Yes; status: Yes;scroll:no;")
}
</script>

父窗口html 调用

'这是GridView模板里面的调用
<ItemTemplate>
<input id="btnJudge" type="button" value="Judge" onclick="ShowWindow('<%#DataBinder.Eval(Container.DataItem,"SNO") %>')" />
</ItemTemplate>

子窗口web得到父窗口传过的值

Dim strIssueNo As String = Request.QueryString("SNO").ToString

三.关闭子窗口刷新父窗口

父窗口

'父窗口
<script type="text/javascript" language=javascript>
function ShowWindow(SNO)
{

var sret=window.showModalDialog("LabJudge.aspx?SNO="+SNO,"","dialogHeight: 700px; dialogWidth: 680px; dialogTop: 100px; dialogLeft: 100px; edge: Raised; center: Yes; help: Yes; resizable: Yes; status: Yes;")

  if(sret == "refresh")
  {
    window.location.reload();
  }

}
</script>

用上面的方式多次刷新会出现错误“新整理网页，必须重新传送资讯”用以下代替，就会解决此问题
