Hotkey On Keypress

smithygotlost · #1 (**permalink**) 06-21-09, 08:42 PM

Heya Guys

Ive got a scrip that on a given key press uses location.href ='URL' this is great for the way we used to do things, now we made everything java so rather than going to a url i need it to run a javascript function, However after hours of trying i have no idea

i need it to do this

Code:

if (x==key1) location.href='<?echo "charmove($map_link_up,$hex_up)"; ?>';

the full script is below

Code:

<script language="javascript">
var key1="119";
var x='';
function handler(e)
{
  if (document.all) {
  var evnt = window.event;
  x=evnt.keyCode;
}
else
x=e.charCode;
if (x==key1) location.href='<?echo "charmove($map_link_up,$hex_up)"; ?>';
}
if (!document.all){
window.captureEvents(Event.KEYPRESS);
window.onkeypress=handler;
}
else
{
document.onkeypress = handler;
}
 </script>

Any help will be greatly welcomed

Thanks
Mike

You didn't specify what javascript function you wanted to run or what the function is supposed to do.

Getting your script to run a function instead of the command location.href='url' is rather easy.

But I see that you are originally loading the location.href from a PHP function.
So I am a little confused as to what it is you are trying to accomplish.

But no matter, here is how you run a javascript function instead of a command.

Example:

HTML Code:

<html>
<head>
<script language="javascript">
function init_keyboard_events()
{
 if(document.all){document.onkeypress = handler;}
 else{window.onkeypress = handler;}
 }
 
function handler(e)
{
 var x = document.all ? window.event.keyCode : e.charCode;
 if(x == 119){do_something();}
 }
 
function do_something()
{
 alert("Doing something.");
 }
</script>
</head>
<body onload="init_keyboard_events();">
</body>
</html>

sorry sorry sorry my bad

the function it needs to run is

Code:

<script language="javascript">
<!--

var state = 'none';

function showhide(layer_ref) {

if (state == 'block') {
state = 'none';
stopkeys(false);
}
else {
state = 'block';
stopkeys(true);
}
if (document.all) { //IS IE 4 or 5 (or 6 beta)
eval( "document.all." + layer_ref + ".style.display = state");
}
if (document.layers) { //IS NETSCAPE 4 or below
document.layers[layer_ref].display = state;
}
if (document.getElementById &&!document.all) {
hza = document.getElementById(layer_ref);
hza.style.display = state;
}
}
//-->
var xmlhttp

function charmove(roomid,hex)
{
moveplayer(roomid,hex);
createworld();
getmobs(roomid);
}
var mobsoff = false;
function mobtoggle() {
if (mobsoff == false) {
  mobsoff = true;
    document.getElementById("getmobs").innerHTML = "";
} else {
  mobsoff = false;
}
}
function getmobs(roomid) {
  if (mobsoff == true) {} else {
	send_url = "getmobs.php?roomid="+roomid;
	mobsrequester = createRequester();
	mobsrequester.onreadystatechange = function(){
		if(mobsrequester.readyState == 4 && mobsrequester.status == 200){
			document.getElementById("getmobs").innerHTML = mobsrequester.responseText;
		}
	}

	mobsrequester.open("GET", send_url);

	if(OS == 'IE'){
		mobsrequester.send();
	}
	else{
		mobsrequester.send(null);
	}
  }
}
function createworld() {
	send_url = "new_createworld.php";
	requester = createRequester();
	requester.onreadystatechange = function(){
		if(requester.readyState == 4 && requester.status == 200){
			document.getElementById("createworld").innerHTML = requester.responseText;
		}
	}

	requester.open("GET", send_url);

	if(OS == 'IE'){
		requester.send();
	}
	else{
		requester.send(null);
	}
}
function moveplayer(roomid,hex) {
	send_url = "moveplayer.php?roomid="+roomid+"&hex="+hex;
	moverequester = createRequester();
	moverequester.open("GET", send_url);

	if(OS == 'IE'){
		moverequester.send();
	}
	else{
		moverequester.send(null);
	}
}
</script>

i need it to run

Code:

charmove($map_link_up,'$hex_up')

every time the w is pressed however your script allows me to get the alert just not run this function, any ideas

Thanks
Mike
