Solve : changing from page with keys? |
|
Answer» Hi there. Does SOMEBODY knows, how I go to another SITE, by pressing an arrow of the keyboard. I would like to have that if I press the arrow that points to the left -on your keyboard!- (I can't say it correct in English, so forgive me) that it goes to another page (example: page.html). Actually it is a sort of unvisible link, but you can use it, if you press that key. Does anybody knows how to do this? Usually Alt+Left goes back through your browser history and Alt+Right goes forward. Left scrolls left in a wide page, and right scrolls right. I do not think you can easily override these settings in your browser, unless you use something like AutoHotKey which is free and enables you to reprogram your entire keyboard in a very sophisticated way. I actually didn't meant that, because for that you should visited all the other pages first, (even in right orther). I woulded like to have a way, that you can use these keys, if it is the first time you visit the siteIt would not generally be desireable for a web page to have the ability to reprogram the way a user's keyboard works. There is one possibility though: you could use javascript to poll for keypress events, and respond accordingly. That's beyond what I normally do with javascript though, so unless someone else here can help you, you may be better off heading over to a dedicated javascript programmers' forum.This one covers most angles, and avoids explicit messings about with character codes. - Always use quotes, even with numbers, and always use upper-case letters. Code: [Select]document.onkeypress = FUNCTION(e) { switch( String.fromCharCode( (e||event).keyCode ).toUpperCase() ) { case "A": alert("A") // or whatever.. break; case "5": alert("5") break; } }First off all, a thanx for this script. Second, do you know how I let the browser go to another page (and not showing a message like a) if i press the RIGHT ARROW? thanx Blackberry Instead of alert("a"); try window.location="http://www.whatever.com/"; Don't know how to trap right and left cursors keys though. Jude?For some reason, the arrow keys don't fire the onkeypress event. They do fire the onkeydown event though - so that's the first change. I have USED the easy approach above (turning the keycode into a character) because it's easier to see what's going on, and to add new cases. I thought this would have to change with the arrows, but it seems that the keycodes they produce do actually correspond to characters. I have put these characters into a map so it's easier to deal with. Then everything else is the same as before. Code: [Select]document.onkeydown= function(e) { var arrowChars = {up:"&",right:"'",down:"(",left:"%"}; switch( String.fromCharCode( (e||event).keyCode ).toUpperCase() ) { case arrowChars.right: alert("right"); // location.href = "blah.htm"; break; case arrowChars.left: alert("left"); // location.href = "doodah.htm"; break; } } |
