转 JavaScript传值及.Net传值方式总结
一,JavaScript传值,主要用到opener.document……
例如:Trans_aa.htm,Trans_bb.htm
<html>
<head>
<script language="JavaScript" type="text/JavaScript">
<!--

var neww;
function azxfds(axzfds,axcfds,acxfds)
{neww=window.open(axzfds,axcfds,acxfds);
neww.window.focus();
}
//-->
</script>
<title></title>
</head>
<body>
<form>
<input type="text" id="aa"><input type="button" onclick="javascript:azxfds('http://localhost/JavaScript/Trans_bb.htm','Yaldex','width=400,height=300')" value="调出bb.html">
</form>
</body>
</html>
<html>
<head>
<title></title>
</head>
<body>
<script language="javascript" type="text/javascript">
function Valid()
{
var Strbb=document.getElementById("bb").value;
opener.document.getElementById("aa").value=Strbb;
}
</script>
<form>
<input type="text" id="bb"> <input type="button" value="确定" onclick="javascript:Valid();window.close();">
</form>
</body>
</html>
二,.Net传值方式主要有以下几种
1,url传值,如:
CheckPwd.aspx?user=uservalue&pwd=pwdvalue
2,Session传值
如:Session("role")="Administrator"
3,Viewstate("role")="Administrator" ,用法和Session大致相同
4,Context传值
如:页面1.aspx有一个TextBox1.Text,一个Button1,一个function test()
Context.Items.Add("value",TextBox1.Text)
Server.Transfer("2.aspx",True) '如果为FALSE,2.aspx将取不到1.aspx中的值
在页面2.aspx中,提取需要的值
Dim str as string=Context.Items("value").tostring
或 str=Request.From("TextBox1")
但是:str=Request.QeuryString("TextBox1")取不到值,想一想为什么???
还可以调用1.aspx的属性和方法:
Dim 11 as i=Ctype(Context.Handle,1)
11.test()
