Go directly to desired page, in JavaScript

B

Bert Visscher

Hello everyone,

I would like to let visitors of my website be able to go directly to a
desired page, by using a URL like www.example.com?progname. I thought I
could do this as follows:

<html>
<frameset rows="88,*">
<frame name="head" noresize src="head.htm" />
<frameset cols="152,*">
<frame name="menu" noresize src="menu.htm" />
<script language="JavaScript">
prog = location.search
prog = prog.substr(1)
prog = prog.split("&")
if (prog=="progname") { document.write ("<frame name='body' noresize
src='progpage.htm' />") }
else if (prog==...
....
else { document.write ('<frame name="body" noresize src="mainpage.htm"
/>') }
</script>
</frameset>
</frameset>
</html>

I see that the above code doesn't produce a page for the body, but I can't
see why? Could anybody please tell me what I'm overlooking?

TIA and regards, Bert Visscher.

Dag Evertjan,

The way I interpret your reply, the following code should work:

<html>
<frameset rows="88,*">
<frame name="kop" noresize src="kop.htm" />
<frameset cols="152,*">
<frame name="menu" noresize src="menu.htm" />
<script language="JavaScript">
prog = location.search
prog = prog.substr(1)
prog = prog.split("&")
if (prog[0]=="gezondheidslijn") { document.write ("<frame name='body'
src='pi-gezondheidslijn.htm' />") }
else { document.write ("<frame name='body' src='hoofdpagina.htm' />") }
</script>
</frameset>
</frameset>
</html>

I'm afraid it doesn't. Just like before, I see the top and left frame
appear, but there's no body.

TIA and regards, Bert V.

Dag Bert,

prog is not a string but an array.
If the calling url was:

http://mySite.nl/test.html?x=progname&y=blah

if (prog[0] == "x=progname") {
Click to expand...

This
= if (prog[0]=="gezondheidslijn") =
would require zoiets als:
http://mySite.nl/test.html?gezondheidslijn&y=blah
This cannot be the output of a <form>

Do you get javascript errors ?

Please start debugging by inserting a handful of alert()s:

<frame name='body'
<script type="text/JavaScript"> // the 'language=' is depriciated
var prog = location.search
alert(prog) // is there a & in the string ???
prog = prog.substr(1)
alert(prog) // do you see the same without the '?' ?
prog = prog.split("&")
alert(prog[0]) // do you see 'gezondheidslijn' ?
if (prog[0]=="gezondheidslijn"){
alert('ja') // 'if' is given true
document.write("src='pi-gezondheidslijn.htm'")
}
else {
alert('nee') // false
document.write("src='hoofdpagina.htm'")
}
</script>
/>

Are the two links correct ?

Hoi Evertjan,

I flipped a couple of quotes, and ended up with the following complete code:

<html>
<frameset rows="88,*">
<frame name="kop" noresize src="kop.htm" />
<frameset cols="152,*">
<frame name="menu" noresize src="menu.htm" />
<frame name="body"
<script type="text/JavaScript">
var prog = location.search
alert(prog) // is there a & in the string ???
prog = prog.substr(1)
alert(prog) // do you see the same without the '?' ?
prog = prog.split("&")
alert(prog[0]) // do you see 'gezondheidslijn' ?
if (prog[0]=="gezondheidslijn")
{
alert("ja") // 'if' is given true
document.write('src="pi-gezondheidslijn.htm"')
}
else
{
alert("nee") // false
document.write('src="hoofdpagina.htm"')
}
</script>
/>
</frameset>
</frameset>
</html>

I think we're getting closer:
This time around, regardless of whether I add "?gezondheidslijn", I get a
body...but it stays blank. And, as if that's not curious enough, I'm not
getting any of the alerts.

Oh, I nearly forgot to write that I'm not getting any error messages.

TIA and regards, Bert V.

Tja, Bert, dan wordt de hele script niet uitgevoerd in een frame
declaratie!!!

Dit werkt wel:

<html>

<script type="text/JavaScript">
function kies(x){
myBody.location.href=
(location.search.substr(1).split("&")[0]==
"gezondheidslijn")
?"pi-gezondheidslijn.htm":"hoofdpagina.htm"
}
</script>

<frameset rows="88,*" onLoad="kies()">
<frame name="kop" noresize src="kop.htm" />
<frameset cols="152,*">
<frame name="menu" noresize src="menu.htm" />
<frame name="myBody" />
</frameset>
</frameset>

</html>

[ik heb de code sterk verkort en de naam "body" vervangen,
omdat dat soms een "reserved word" zou kunnen zijn.]

I had a similar problem. I got it to work with iframes using the
following:

<script language="JavaScript">
page = "main.htm"; //default page
if(location.search) page = location.search.substring(1);

//insert extra logic here if want

document.write('<iframe src="' + page + '" id="myIframe"
name="myIframe" width="630" scrolling="no"
frameborder="1"></iframe>');
</script>

You could add logic in there, like:

if (page = "help") page = help.html;

I hope this helps.

Jim
