Access denied in javascript when try to see contents of page in javascript opened window

[admyc]

Hello

I am trying to write some javascript that will open a new web-page in
a new window and then be able to determine if the web-page that has
been opened contains certain text.

I am opening the new window with:
newpage = window.open("http://www.somewebaddress.com/
index.html","newpage","width=400,height=200,left=400,top=300,resizable=1,status=1,scrollbars=1");

I am then trying to see if it contains certain text by using:
if(newpage.document.getElementsByTagName('body')[0].innerHTML = =
"text") alert("contains the text");

However this line seems to produce an error that says "Access denied".

Does anyone know why this is or another way of achieving my goal?

Thanks

AM

It is absolutly forbiden to acces to contain of another domain ... !

So your browser doesn't allow you to parse the page displayed in your
popup because probably this page comes from another domain.

Test with a file comming from your own site
to see if your script is right.

I am opening the new window with:
newpage = window.open("http://www.somewebaddress.com/
index.html","newpage","width=400,height=200,left=400,top=300,resizable=1,status=1,scrollbars=1");

I am then trying to see if it contains certain text by using:
if(newpage.document.getElementsByTagName('body')[0].innerHTML ==
"text") alert("contains the text");

However this line seems to produce an error that says "Access denied".

Acces denied to the other site's contain .... !

`newpage' should be declared with `var'. The window name (second argument)
should be distinguishable in order not to reuse windows from other sites.
As for the third argument, omit "left=...,", "top=...,", and all `=1'.

I am then trying to see if it contains certain text by using:
if(newpage.document.getElementsByTagName('body')[0].innerHTML = =
"text") alert("contains the text");

However this line seems to produce an error that says "Access denied".
