CodeLifter.com - Accent JavaScript Browser 1.0 Kit

JavaScript web-based browsers are an interesting idea, and they've been built by a number
of sites. However, do be aware that they have a number of shortcomings. For instance,
capturing pages that themselves contain frame-buster scripts (like our own -- see the
index) is not possible, and standard links that subsequently use target="_top" will
co-opt the frameset used in the javascript browser.

Nonetheless, this overall approach has a great deal to recommend it, and the scripts
we show here are excellent samples for studying techniques and solid springboards for
going further with your own ideas.

IMPORTANT

Remember that Alt-F4 will close any fullscreen window.
Sites that use frame-busters or _top link targets may become trapped
in the fullscreen window, and must be closed with Alt-F4.

PLEASE NOTE

Though this site and all of our other sites
[ www.CodeBrain.com www.CodeBelly.com www.BrainCode.com ]
do not use frame-buster scripts, most links on them do contain target="_top"
-- so these are not good choices for testing the demo.

Also, before you ask, as many will, it is not possible to launch a fullscreen window
like the JavaScript browser independently. It must be launched from an opener page.

There is also no way to eliminate or avoid the dialogue request in
Windows Internet Explorer if you attempt to self.close( ) the launching page after
starting the fullscreen popup that contains the JavaScript browser.

THE SCRIPTS

The Accent JavaScript Browser consists of five html pages, one css file,
and one background graphic image (shown at the bottom).
All should be placed together in the same directory.

document.Address.Entry.value = Now;
}else{
document.Address.Entry.value = 'http://';
}
}

var whereTo;
var parsing;
function goThere(){
whereTo = '';
whereTo = document.Address.Entry.value;
parsing = whereTo.substring(0,7);
parsing = parsing.toLowerCase();
if (parsing != 'http://') whereTo="http://"+whereTo;
if (whereTo.length>12){
    parent.Content.location.href = whereTo;
    document.Address.Entry.value = whereTo;
    document.Address.action = 'navigation.html'+'?'+whereTo;    
}
