一，从子窗口传值到父窗口
父窗口html
<script type="text/javascript" language="javascript"">
var fHeaderPkey="";
function btnApp1_onclick(t,t1)
{
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
." language="javascript" onclick="btnApp1_onclick('txtApp1','txtEngName1')" />
父窗口web里面取控件的值
Dim strEngName1 As String = Request("txtEngName1").Trim
子窗口（跳出的窗口）html回传值
<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
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
传两个参数的。
<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
<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
三.关闭子窗口刷新父窗口
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
function ShowWindowBJ(cmd,SNO)
{
eval(cmd);
var retB=window.showModalDialog("BatchJudge.aspx?SNO="+SNO,"","dialogHeight:500px; dialogWidth:600px; dialogTop:60px; dialogLeft: 100px; edge: Raised; center: Yes; help:no; resizable: Yes; status: Yes;scroll:no")
if(retB== "refresh")
{
// window.location.reload();
//刷新出现错误“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。
window.location.href=window.location.href;
}
}
</script>
子窗口
<script type="text/javascript" language=javascript>
function closed()
{
window.returnValue = "refresh";
window.close();
}
</script>
</head>
<body onunload="closed()">
四.子窗口的刷新。打开子窗口，关掉重新打开子窗口不刷新子窗口解决，是因为url相同，url加变量值让其打开不同
与上次。
function ShowWindow(SNO,PN)
{
var num=Math.random();
var sret=window.showModalDialog("PEJudge.aspx?SNO="+SNO+"&PN="+PN+"&num="+num,"","dialogHeight: 655px; dialogWidth: 759px; dialogTop: 60px; dialogLeft: 100px; edge: Raised; center: Yes; help:no; resizable: Yes; status: Yes;scroll:no")
if(sret == "refresh")
{
window.location.href=window.location.href;
}
}
</Script>
