如何用请求字符串传值给用模式窗口打开的aspx页面

2005-12-28 13:15 585 查看

模式窗口是一种方便的当前页面扩展的方式，但是aspx文件只能作为HTM文件的IFRAME才能用这种方式调用。同时，请求字符串也是一种方便常用的页面间传值的方法，那么怎么样使两者给合起来，就是实现如何用请求字符串传值给用模式窗口打开的aspx页面呢？
我们可以用JS脚本实现这种功能：
1.调用页面代码：
<script language="javascript">
function GetCorrelativeItemId()
{
rdl = document.getElementsByName("rdlSystem");

input = document.getElementById("txtCorrelativeItem");
sysid = "";
for(i = 0 ; i < rdl.length ; i++)
{
if(rdl[i].tagName == "INPUT")
{
if(rdl[i].checked)
{
sysid = rdl[i].value;
}
}
}

arg = window.showModalDialog("SearchItemC.htm?sysid="+sysid,window,"resizable:1;");
if(arg!=null)
{
input.value = arg;
}
}
</script>

2.打开的HTM文件的代码（SearchItemC.htm）：

function ResolveUrl()
{
var frm = window.frames[0];
frm.location = location.toString().replace("C.htm","C.aspx");
}
<HTML>
<HEAD>
<script language="javascript">
function ResolveUrl()
{
var frm = window.frames[0];
frm.location = location.toString().replace("C.htm","C.aspx");
}
</script>
</HEAD>
<BODY style="margintop:0;marginleft:0;marginright:0;marginbottom:0" onload="ResolveUrl()">
<table align="left" cellpadding="0" cellspacing="0" width="100%" height="100%" ID="Table1">
<tr>
<td valign="top" width="100%" height="100%"><iframe id="ifmain" border="0" width="100%" height="100%"></iframe></td>
</tr>
</table>
</BODY>
</HTML>
3.Aspx文件(SearchItemC.aspx)代码：
Request.QueryString["sysid"].Trim();
function GetCorrelativeItemId()
{
rdl = document.getElementsByName("rdlSystem");

input = document.getElementById("txtCorrelativeItem");
sysid = "";
for(i = 0 ; i < rdl.length ; i++)
{
if(rdl[i].tagName == "INPUT")
{
if(rdl[i].checked)
{
sysid = rdl[i].value;
}
}
}

arg = window.showModalDialog("SearchItemC.htm?sysid="+sysid,window,"resizable:1;");
if(arg!=null)
{
input.value = arg;
}
}

function GetCorrelativeItemId()
{
rdl = document.getElementsByName("rdlSystem");

input = document.getElementById("txtCorrelativeItem");
sysid = "";
for(i = 0 ; i < rdl.length ; i++)
{
if(rdl[i].tagName == "INPUT")
{
if(rdl[i].checked)
{
sysid = rdl[i].value;
}
}
}

arg = window.showModalDialog("SearchItemC.htm?sysid="+sysid,window,"resizable:1;");
if(arg!=null)
{
input.value = arg;
}
}

function GetCorrelativeItemId()
{
rdl = document.getElementsByName("rdlSystem");

input = document.getElementById("txtCorrelativeItem");
sysid = "";
for(i = 0 ; i < rdl.length ; i++)
{
if(rdl[i].tagName == "INPUT")
{
if(rdl[i].checked)
{
sysid = rdl[i].value;
}
}
}

arg = window.showModalDialog("SearchItemC.htm?sysid="+sysid,window,"resizable:1;");
if(arg!=null)
{
input.value = arg;
}
}

function GetCorrelativeItemId()
{
rdl = document.getElementsByName("rdlSystem");

input = document.getElementById("txtCorrelativeItem");
sysid = "";
for(i = 0 ; i < rdl.length ; i++)
{
if(rdl[i].tagName == "INPUT")
{
if(rdl[i].checked)
{
sysid = rdl[i].value;
}
}
}

arg = window.showModalDialog("SearchItemC.htm?sysid="+sysid,window,"resizable:1;");
if(arg!=null)
{
input.value = arg;
}
}
