Window Openning detection

[abakar]

I was wondering if there was a way to detect if the current browser
openned a new window. For example, I have a link like <a
href=&quot;

http://www....&quot;

target=&quot;_blank&quot;>text</a>

And I would like to know if a window was openned using this like (the
_blank target opens a new window, but I do not think it has a name) I
would like to be able to detect this without editing the <a> tag with
something like onClick, but just be able to detect if the window is open
(or was openned) using a if statement without having to alter the HTML
code itself.

Thak you

Name the new window, then use:

windowName.closed

This returns false if the window is open, so you may want to invert it, sometimes seting things false gives problems.

if(!windowName.closed){do whatever cause the window is open}

Also, I guess the windowName returns true if it exists &quot;Alright whatever man, I'll hook up the hair, but I aint touchin the ring...Cause I'm still a pla--yer&quot;

how would you name it using the code above? can you name a window that you open using target=_blank? adam@aauser.com

I think that you can't escape from using the onClick event. Here is how you can do it without editing the <a> tag.

<script language=&quot;JavaScript&quot;>
function checkLinks(){
for (var i=0; i<document.links.length; i++)
if (document.links.target==&quot;_blank&quot
document.links.onclick = newWinAlert;
}

function newWinAlert(event){
// do what you like;

}

document.onload=checkLinks;
</script>

WARNING: I didn't test it but it should work with both IE and NN.

I tried to use the following code with a onLoad=&quot;checkLinks()&quot; in the body tag, but it seems the window.document.links.onClick = newWinAlert; executes even if the click on the link is not done (it executes on page load...) anything else I could do...or did I do anything wrong?


<script language=&quot;JavaScript&quot;>

function checkLinks(){

for (var i = 0; i < document.links.length; i++)
{
if (document.links.target == &quot;_blank&quot
{
window.document.links.onClick = newWinAlert;
}
}
}

function newWinAlert()
{
alert(&quot;It worked&quot;
}

</script>

I think you want to open the window properly, rather than using the _blank atrget idea.

<a href=&quot;javascriptpen('page.html','windowName','attributes')&quot;>Link</a>

This gives you absolute control over the new window.

luciddream -As far as I can see, there is no way to reference a window created by &quot;target=_blank&quot;, unless there is some child array somewhere, but I can't find it right now!

- Check out the FAQ which gives all the attributes, for a new window (width, height etc.) &quot;Alright whatever man, I'll hook up the hair, but I aint touchin the ring...Cause I'm still a pla--yer&quot;

Abakar,
You missed the index when reffering to the links collection, so your code points to the collection and not to a member of it.

You also should set a return value for the newWinAlert() - if it returns &quot;true&quot; the new window is opened, else it is canceled. So I replaced your function &quot;alert(...)&quot; with &quot;confirm(...)&quot; just to demonstrate this.

bellow is the corrected code, I tested it in IE 5.5 and NN 4.7 and it worked:

<script language=&quot;JavaScript&quot;>

function checkLinks(){

for (var i = 0; i < document.links.length; i++)
{
if (document.links.target == &quot;_blank&quot
{
window.document.links.onclick = newWinAlert;
}
}
}

function newWinAlert()
{
return confirm (&quot;Do you want a new window?&quot;
}

</script>

sorry Abakar, I had to turn-off the &quot;Process TGML&quot; option of the message or it takes for itallic formating. I just noticed that you probably had the same problem.

Here is the code one more time (may be the only real problem that you had is the char case in &quot;onClick&quot; correct is &quot;onclick&quot; and it is case sensitive ). This time I include the whole code that I used for testing:


<head>

<script language=&quot;JavaScript&quot;>
function checkLinks(){

for (var i = 0; i < document.links.length; i++)
{
if (document.links.target == &quot;_blank&quot
{

window.document.links.onclick = newWinAlert;
}
}
}

function newWinAlert()
{
return confirm (&quot;Do you want a new window?&quot;
}
</script>
</head>

<body onload=&quot;checkLinks();&quot;>
<a href=&quot;&quot; target=&quot;_blank&quot;>This is the test link;</a>
</body>
</html>
