我使用以下代码打开一个弹出窗口并传递查询字符串的ID。
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script language="javascript" type="text/javascript">
function openwindow(divID) {
window.open("pp.html?id="+divID+"","","status=yes, location=yes, width=700, height=400");
}
</script>
</head>
<body>
<a href="#" onclick="openwindow('one')" id="one">One</a>
<br />
<a href="#" onclick="openwindow('two')" id="two">Two</a>
<br />
<a href="#" onclick="openwindow('three')" id="three">Three</a>
</body>
</html>
场景是,我需要在弹出窗口中显示DIV,其id与querystring值类似。弹出窗口代码是
<html>
<head>
<script language="javascript" type="text/javascript">
function getid() {
if (Request.QueryString("id")!=null)
var id = Request.QueryString("id");
document.getElementById(id).style.display = "block";
}
</script>
</head>
<body onload="getid();">
<div style=" overflow:hidden">
<div style="margin-left:-5px;"><input type="file" style="" /></div>
</div>
<div style="width:200px; height:200px; border:1px solid #999999; background- color:#CCCCCC; display:none" id="one">Hello! ONE</div>
<div style="width:200px; height:200px; border:1px solid #999999; background-color:#CCCCCC; display:none" id="two">Hello! TWO</div>
<div style="width:200px; height:200px; border:1px solid #999999; background-color:#CCCCCC; display:none" id="three">Hello! THREE</div>
</body>
</html>
现在,弹出窗口显示错误“请求未定义”。
请帮我解决问题。

您正在将ASP.NET服务器端语言与javascript混合使用,这当然是不可能的。试试这样:
function getid() {
<% if (Request.QueryString("id") != null) { %>
var id = '<%= Request.QueryString("id") %>';
document.getElementById(id).style.display = 'block';
<% } %>
}
如果您不使用服务器端语言,可以使用以下函数在javascript(taken from here)中读取查询字符串参数:
function gup(name)
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( window.location.href );
if( results == null ) {
return "";
} else {
return results[1];
}
}
并像这样使用:
function getid() {
var id = gup('id');
if (id != '') {
document.getElementById(id).style.display = 'block';
}
}
