Javascript Menu not loading images

John Ortt

Hi Everyone,

I have created a Javascript menu for my site which uses frames. The first
stage loads fine but I want two drill down menus ("About Me Menu" and
"Projects Menu"). The pages load fine, but the images aren't displayed,
instead the alt text is shown. The images come up after you "Mouse Over"
them but not before......can anybody spot any errors in my code which could
be doing this please. For info, I have 4 images for each button, to take
into acount whether the button had been used and to give a mouse-over image
for each state. I have also deleted the code for items 3-5 as they are
commercially sensitive.

Thanks in Advance,

John

Ok, I've looked at what's happening and I think I have narrowed down the
problem. The main "frames.html" creates the left-hand frame with the menu
on it. The first menu loads correctly because the page is being loades from
scratch, but the second page doesn't. I can't spot a difference in the page
code (copied below for info) so I can only assume some sort of refresh is
needed.

If anybody could tell me if I'm on the right lines I'd really appreciate it,

Thanks,

John

The following code works:

<html><head onLoad="top.evalImage(1)","top.evalImage(8)">
<TITLE>Welcome to John Ortts Internet Page - Contents Menu</TITLE>
</head><body bgcolour="white">
<A target=Left
onclick="top.aboutmemenu();top.amcount()"
onmouseout="top.evalImage(1)"
onmouseover="top.evalRollon(1)">
<img src="About Me.gif" alt="About Me" width=250 height=50 border=0
name="about"></A>
<A href="top.projects()" target=Left
onclick="top.projectsmenu();top.projectcount()"
onmouseout="top.evalImage(8)"
onmouseover="top.evalRollon(8)">
<img src="Projects.gif" alt="Projects" width=250 height=50 border=0
name="projects"></A>

</body></html>
This code doesn't buit is essentially the same:

<html><head
onLoad="top.evalImage(98)","top.evalImage(2)","top .evalImage(4)">
<TITLE>Welcome to John Ortts Internet Page - About Me Menu</TITLE>
</head><body bgcolour="white">
<A target=Left
onclick="top.mainMenu();top.uponecount()"
onmouseout="top.evalImage(98)"
onmouseover="top.evalRollon(98)"
onLoad="top.evalImage(98)" return="false">
<img src=top.evalImage(98) alt="Up" width=250 height=50 border=0
name="up"></A>
<A href="mycv.html" target=Right
onclick="top.cvcount()"
onmouseout="top.evalImage(2)"
onmouseover="top.evalRollon(2)"
onLoad=top.evalImage(2) return="false">
<img src="top.evalImage(2)" alt="My CV" width=250 height=50 border=0
name="cv"></A>

</body></html>

Not when that url is on an Intranet,

(and I don't have webspace outside the company).

GeoCities.. (It's a big internet)

Alternatively, if 'the company' is serious about

Since the difference is that the images don't load,
the obvious place to focus is the "src" attributes
of the <img> tags.

In the following (non-working) code, you're trying
to assign Javascript variables as src attributes.
You can't mix Javascript and HTML like that:

<html><head
onLoad="top.evalImage(98)","top.evalImage(2)","to p.evalImage(4)">
<TITLE>Welcome to John Ortts Internet Page - About Me Menu</TITLE>
</head><body bgcolour="white">
<A target=Left
onclick="top.mainMenu();top.uponecount()"
onmouseout="top.evalImage(98)"
onmouseover="top.evalRollon(98)"
onLoad="top.evalImage(98)" return="false">
<img src=top.evalImage(98) alt="Up" width=250 height=50 border=0
name="up"></A>
<A href="mycv.html" target=Right
onclick="top.cvcount()"
onmouseout="top.evalImage(2)"
onmouseover="top.evalRollon(2)"
onLoad=top.evalImage(2) return="false">
<img src="top.evalImage(2)" alt="My CV" width=250 height=50 border=0
name="cv"></A>

</body></html>

Geocities (yahoo) offers free webspace that is mostly useless but works
great for this sort of thing.

You could cut your code about in half by using "switch"
statements in place of the "if"s. There are even better
ways to do this, that don't involve passing numeric codes.

Please get rid of the series of functions that each increment
a single global variable.

Your call to the function:
function uponecount()
{++up_1}

can be replaced by:
top.up_1++

Thanks for the info Andrew.

I didn't know there were places offering free webspace. I will try to put
it on the GeoCities website later on in the week and repost.

I will also try to include some of the tips Lee gave me to shorten the code.

The site is essentially a personnal homepage for me on the company intranet
(They have an area set aside for the employees).

It is intended to tell people what I do and how I do it and gives links to
the department.

For this reason it isn't business critical and there is no way the company
are going to release funding for me to develop it :(

But I would like to get it working if possible just to improve my knowledge
of the subject.

Thanks again,

John

That is a good idea. I wrote a page on just how
much it can help to shorten and simplify code.

The article is more focused on Java (a different
language to JS) but I feel you might find some
valuable tips in it in any case..

People who are trying to improve their knowledge
are very welcome on this group, especially if
they have displayed that they can benefit from
the advice they receive.

Continue reading the froup and you may spot the
answer to your problem, but if you simplify your
code and still do not get the problem sorted, post
it to GeoCities and make a new post on this thread
with the URL.

I am confident someone will be able to spot the error.

Thanks Andrew,

I haven't looked at the page you linked yet but I will do so tonight.

Also, I didn't fully understand Lee's post on getting rid of the "If"
statements so until I do, I have just used a tidier "if" format which I
found on "Webmonkey".

I have reposted the tidier code allong with a geocities site in the
newsgroup.

Thanks for your time once again,

John Ortt
