open new window

[Andy]

Hi,

I have this code in the head of the page:

script language="JavaScript" type="text/JavaScript">
<!--

function goTo(targ,selObj,restore){ //v3.0
eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
if (restore) selObj.selectedIndex=0;
}
//-->
</script>

and this bit in the body section:

<form name="form1" method="post" action="">
<select name="select" onChange="goTo('self',this,0)">

Simple put I want the new page to open in a new window, I assumed that
changing the 'self' bit to 'blank' would work but all I get are JavaScript
undefined error messages.

Does anybody have any other ideas as to what I could try ?

Thanks

Yikes. Bad use of eval. You will probably never need to use eval, as
there are better alternatives.

Just use:
function goTo(tObj,selObj,restore) {
tObj.location=selObj.options[selObj.selectedIndex].value;
...
and
<form name="form1" method="post" action="">
<select name="select" onChange="goTo('self',this,0)">
onchange="goTo(self,this,false);"

This code is only built to open in existing windows.
Does anybody have any other ideas as to what I could try ?

function goToNew(winName,selObj,restore) {
var win = window.open(selObj.options[selObj.selectedIndex],winName);
if (restore) {selObj.selectedIndex=0;}
return win;
}

called as, e.g.:
onchange="goToNew('_blank',this,false);"

Why are you using eval()? I don't see why you can't just make targ an
object reference and then write:

targ.location.href = selObj.options[ selObj.selectedIndex ].value;

Notice that there is no need to convert the value property to a string.
The form control values are *always* returned as strings.
if (restore) selObj.selectedIndex=0;
}

Remove this delimiter along with the first.

To work with the changes above, change the call to

goTo(self,this,false)

I changed the last argument to false because it makes more sense to pass
booleans when evaluating booleans.

That's because "self" is an object reference to the current window
(equivalent to window.self or window), whereas "blank" isn't defined at
all.

A call to window.open(), perhaps?

Two things to note:

1) Don't perform navigation actions on the "change" event.
2) Avoid new windows completely, if possible.

If I use my mouse wheel to change the value, the event will fire every
time even though I probably haven't chosen a destination yet. Similarly,
if I make a mistake when choosing a value, I will not get an opportunity
(unless I'm very quick) to correct it. Use a button instead.
