warning on leaving intranet 2

[Rydel]

I am designing an Intranet for a company and I would like to have an automatic warning dialog whenever there is a link outside of our intranet (

http://ourIntranet/someFile.asp)

to an outside resource (

http://www.someServer.com/someFile.htm)

and user clicks on it. Of course, I can create "onclick" handler for all links, but this is too cumbersome and difficult to maintain. tt would be much better if there was a generic way to issue this warning "once and for all". All Intranet users have IE5.0 or IE5.5 (what a blessing! ) Any help greatly appreciated! ---

What you want is a DHTML behavior (

http://msdn.microsoft.com/workshop/author/behaviors/overview.asp)

that uses AttachEvent (

http://msdn.microsoft.com/workshop/author/dhtml/reference/methods/attachEvent.asp)

to attach an onclick event handler to every hyperlink in the document automatically and can perform a short check on the Event.srcElement.href (

http://msdn.microsoft.com/workshop/author/dhtml/reference/properties/href_1.asp)

property, and if the property doesn't meet the criteria for an intranet page, you activate a popup with the onbeforeunload event, which can send any warning you want to the user before the browser navigates to the next page. Check out

http://msdn.microsoft.com/workshop/author/dhtml/reference/events/onbeforeunload.asp

(Enough links for ya?) This can all be done from a single external file, with the extension .htc, which is referenced from a style declaration at the top of the page. Once you get the hang of it, DHTML behaviors can be a useful programming tool for IE-specific intranets.
