"null" and "" are not the same thing in JavaScript.
How about something like
function twoTheSame(one, two, three)
{
if(((one == two) && (one != null) && (one != "undefined") && (one != ""))
||
((one == three) && (one != null) && (one != "undefined") && (one != ""))
||
((two == three) && (two != null) && (two != "undefined") && (two !=
""))) {
return true;
} else {
return false;
}
}
function popup( pageToLoad, winName, width, height)
{
if (twoTheSame(document.updatefav.myselectbox.value,
document.updatefav.myselectbox1.value,
document.updatefav.myselectbox1.value)) {
xposition=200; yposition=300; width=250; height=90
args = "width=" + width + "," + "height=" + height + "," +
"location=0," + "menubar=0," + "resizable=1," + "scrollbars=0," +
"status=0," + "titlebar=0," + "toolbar=0," + "hotkeys=0," + "screenx=" +
xposition + "," + "screeny=" + yposition + "," + "left=" + xposition + ","
+
"top=" + yposition;
window.open( "processed.htm","popup_win",args );
return false;
} else {
return true;
}
}

Subject: Javascript on selectboxes
I have this script that is called when a form is submitted. It is supposed
to display a popup window if two of the three selectboxes are the same. It
works good except that if the first box is selected and the other two are
null or empty then the popup appears. Same thing happens with the second
box selected and the first and third null or emtpy, and the same with the
third box. Otherwise it works great with two boxes selected that might be
the same. Any ideas on where I have gone wrong with this one?
TIA,
cami
