Is it possible to make a link with 'target' attribute run script on another page?
*Update: Ultimately I've decided that accomplishing exactly what I want here isn't possible due to the issues it poses to security. Kalle's answer below gives a solution that is closest to what I want to accomplish. In order to solve my problem I've created scripts on both pages and will use a sort of push notification that is routed through the server in order for them to communicate. Thanks for the help!! *
I have two pages. Both windows a开发者_JAVA技巧lready exist independently. Page two has a function declared in JS.
I would like to be able to call the function in window two by clicking a link in window one.
Page 1:
<html>
<head>
<title>This is a title!</title>
</head>
<body style="background: lightblue">
<a href="#" target="my_target" onClick="clicked()">Click Me!</a>
</body>
Page 2:
<html>
<head>
<META HTTP-EQUIV="Window-target" CONTENT="my_target" />
<title>This is a title!</title>
<script type=text/javascript>
function clicked() {
alert('test');
}
</script>
</head>
<body style="background: lightblue">
</body>
Since it is on the same domain you can get this to work but would have to change the way you were doing it a little.
First off you would have to open it in a popup using this syntax rather than a new tab:
newwindow=window.open(url,'name','height=200,width=150');and then you could simply call newwindow.clicked() after the popup is called.
update
just did a quick test and this will open it in a new tab. (sorry its been a while since I used the open function.
newwindow=window.open(url,'name');Just noticed also that you should wait for the popup to load. So in my Example it would look a little something like this (with jQuery):
var newwindow = window.open('http://www.tylerbiscoe.com/vb/new.html');
$(newwindow).load(function(){
newwindow.clicked();
});Ok, brand new answer. I hope this is what you were thinking. This is however, when you open page 2 from page 1.. So basically, page 1 would know who page 2 is..

Page 1
<html>
<head>
<title>Page 1</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<style>
.ajaxlink {color: blue; cursor: pointer; border-bottom: 1px dotted blue;}
</style>
</head>
<body>
<span id="open_page_2" class="ajaxlink">Open new window</span>
<br>
<br>
<a href="#" target="my_target">Click Me!</a>
<script>
$('#open_page_2').click(function(){
child = window.open('test2.php','page_2','width=600,height=600');
});
$('a[target=my_target]').click(function () {
child.SecondPageFunction();
return false;
});
</script>
</body>
</html>
Page 2
<html>
<head>
<title>Page 2</title>
</head>
<body>
<h1>Your seeing page 2!</h1>
<script>
function SecondPageFunction () {
alert('Second page action got triggered!');
}
</script>
</body>
</html>
The script must be a part of the page you're opening in the new window. You're absolutely correct about it being a security flaw if it was elsewise allowed.
You could add some query string argument that could be picked up onload by javascript in the page you are opening and call your function if the query string arg is present.
