Javascript / Client Side Development :: "about:blank" oepns new browser window


	"about:blank" oepns new browser window "about:blank" oepns new browser window I am writing a webpage that will run on other machines that I may or may not know about. My page is framed where frame1 controls the content of frame2. What I have found is that if the page in Frame2 fails to load and I get an error page. when I detect an error page I want to set frame2.location.href = "about:blank" and then write a temp error page until the server becomes available again. The problem is that the security on some systems causes the "about:blank" to open a new browser window. I don't want a new window. Is there anyway to detect that the system is opening up a new window as opposed to the existing frame ? Can my script test for the security setting on another frame, to see if the security is 'restricted' no matter where the security was set, either in the declaration of the frame or the security tab of IE ?

No. You can't test for security settings. Think about what you are asking though. A user has a particular Security Setting and you are asking how to circumvent that Setting. Think about it. Then, instead of using about:blank use a blank file that you can cache so it is available if the server is down. -- Randy Chance Favors The Prepared Mind comp.lang.javascript FAQ - http://jibbering.com/faq/index.html Javascript Best Practices - http://www.JavascriptToolbox.com/bestpractices/ On May 22, 10:36 pm, Randy Webb <HikksNotAtH@aol.com> wrote: - Hide quoted text - > sid said the following on 5/22/2007 2:54 PM: > > "about:blank" oepns new browser window > > I am writing a webpage that will run on other machines that I may or > > may not know about.

Is there any way that I can force this ? I am simply setting the href the that equal to that of the empty frame. Main.location.href = "empty.htm" when I detect an error. Is there a better way to do it ? Thanks Eli.

How do you detect if the other frame failed to load, anyway? Another question, if you get an error screen, at least in firefox, that frame can't be easily set an address - window.top.other_frame.location is inaccessible...

" set in the frame tag. then check the contents, either its blank "" or the script can read something from the page "Action Cancelled". if the frame loaded from a foreign domain you can not read the location.href, but you can set it.
