<input type="button" name="abc" value=" Copy 2 Clipboard" onclick="window.top.value=this.value;" />
-
<a href="test.html" target="_blank">Open a new window!!!!</a>
-
<input type="text" name="abc1" value="" onclick="this.value=typeof window.top.value!='undefined'?window.top.value:'';"/>
-
Now i m opening the same page at a different window.
There if i click on the text box then i m getting the undefined value of top.value
Why it's happening?
can't i get the [b]top.value[b] from any children window of that top window?
Where i am wrong?

Now it's working as i expected!
:-)
What is this window.top.value?
Never heard about this.
Not sure what you were trying to do. window.top usually refers to the top frame. If you wanted to set a value, you could have set a global variable.

See what i am trying to do i want to save a value some where and i want to make available this value to any children window of that window.
So i thought it's better to save in top window's reference.
Anyway i can also save in that window's reference.
Anyway by this experiment i came to know the actual reality of top. :-)

Yes, window.test_value would have been enough. Then from the child windows, window.opener.test_value should give you the value you need.

Yeah that also be fine. :-)
Thanks Acoder!
No problem. You're welcome :)
No problem. You're welcome :)
Thanks again!!
Sorry Acoder I forgot to mention one thing that in my case there is no way rather than using top.
Actually i want to save the value from a window which can be at any frame of the main window. And the child window may be from another frame of the main window.
So here is only option is top.
Debasis Jana.
In that case, you could use window.top.test_value or top.opener.top.test_value (for frame in a popup window).

Yeah that's what i m using top ..and i already found the solution.
i am using this function to find out that value. -
function getTopVal(){
-
var tmp = window;
-
while(tmp.opener){
-
tmp = tmp.opener;
-
}
-
alert(tmp.top.value);
-
}
-
Anyway, Thanks for your help!
Yeah, I did see that, but I would avoid "value" because it can be confusing.

Ohh...!!!
That's what you were saying.....test_value.
lolz!
