问题
I want to link to a url and after the destination page opens, pop up a window over it. I've seen some examples of this but don't know how to code it. I'm a .NET developer but perhaps this needs javascript? Anyone know how to do it?
Page 1
Link 2 Page 2 ---> Page 2 opens... Popup opens over Page 2.
Thanks.
回答1:
Approach #1:
In Page 2:
<script>
if (document.referrer === "URL of Page 1 goes here")
{
window.open("URL of popup goes here", "_blank");
}
</script>
Thus the popup will only appear if you arrived at Page 2 via a link from Page 1.
Approach #2 (if you cannot modify Page 2):
In Page 1:
<script>
function page2popup()
{
window.open("URL of popup goes here", "_blank");
}
</script>
<a href="URL of Page 2 goes here" onclick="page2popup();">Page 2</a>
回答2:
if you are doing this in html, then
page1.html
<html>
<head>
</head>
<body>
<a href="page2.html">click to go to page to page2</a>
</body>
</html>
page2.html
<html>
<head>
<script type="text/javascript">
function popup(){
//alert("this is page 2");
window.open("http://www.geekzgarage.com");
}
</script>
</head>
<body onload="popup()">
this is page 2 and popup window is opened as provided in the link given..
</body>
</html>
