F1 key to go to a link

[Sue]

Hi,

I'm new to javascript and what I want to do is when user press F1 key,
it will show the help page. Can anyone show me the javascript code.
The link of the help page is help/work/Default_CSH.htm#messageBar
Thanks.

Seems you are new to this NG to, as this was discussed some time ago.

It is impossible with clientside javascript on a browser.

It already does show the help page ... of the browser. And that is good so.

You don't need any code for that, let alone "javascript" code.

The link of the help page is help/work/Default_CSH.htm#messageBar

Include an <a ... accesskey="h">Help</help> or something like that instead.
Users don't take kindly on their browser being broken by authors who think
they know better.

It isn't a good idea, but this works in most browsers:

this.onload = function() {
var doc = this.document;
if (!doc) { return; }
doc.onhelp = function() { window.open('help/work/
Default_CSH.htm#messageBar'); return false; };
doc.onkeydown = function(e) { if (e && e.which == 112)
{ window.open('help/work/Default_CSH.htm#messageBar'); return
false; } };
doc = null;
};

Normally onkeyup would be the appropriate event, but to prevent the
browser's help window from opening, you have to use onkeydown (or
onhelp for IE.) Opera will navigate to its help page in any event,
just as it will always show its default context menu.
