Hi All

I a new to javascript. I am using the below javascript for expand
collpase menu. When user clicks to expand the menu, -image appears and
when clicks to collapse the menu,+ image appears. I want to use the
sme script for mouse hover. How can I.

<script type="text/javascript">
document.getElementById('personal_details').style. display='none';
document.getElementById('income_details').style.di splay='none';
document.getElementById('return_details').style.di splay='none';
document.getElementById('filing_details').style.di splay='none';

function switchMenu(id)
{
obj=document.getElementById(id);
col=document.getElementById("x" + id);

if (obj.style.display=='none')
{
obj.style.display='block';
col.innerHTML="<img src='/it_media/v4/n/images/minus2.gif'/>";
}

else
{
obj.style.display='none';
col.innerHTML="<img src='/it_media/v4/n/images/plus2.gif'/>";

}
}

</script>

Just a quick remark: The spaces in the above code.... are they an
artifact when you copied/pasted the code?
If not, start fixing them first (and keep an eye on your errorconsole to
spot syntax mistakes right away).

The code is like this:


<script type="text/javascript">
document.getElementById('personal_details').style. display='none';
document.getElementById('income_details').style.di splay='none';
document.getElementById('return_details').style.di splay='none';
document.getElementById('filing_details').style.di splay='none';
function switchMenu(id)
{
obj=document.getElementById(id);
col=document.getElementById("x" + id);
if (obj.style.display=='none')
{
obj.style.display='block';
col.innerHTML="<img src='/it_media/v4/n/images/minus2.gif'/>";
}
else
{
obj.style.display='none';
col.innerHTML="<img src='/it_media/v4/n/images/plus2.gif'/>";
}
}
</script>

Sorry, the code is like as below. The spaces came while copy/pasting
it.

<script type="text/javascript">
document.getElementById('personal_details').style.display='none';
document.getElementById('income_details').style.display='none';
document.getElementById('return_details').style.display='none';
document.getElementById('filing_details').style.display='none';

function switchMenu(id)
{
obj=document.getElementById(id);
col=document.getElementById("x" + id);

if (obj.style.display=='none')
{
obj.style.display='block';
col.innerHTML="<img src='/it_media/v4/n/images/minus2.gif'/>";

}

else
{
obj.style.display='none';
col.innerHTML="<img src='/it_media/v4/n/images/plus2.gif'/>";

}
}

Erm......

Did you read my message?
Remove the spaces AND keep an eye on your errorconsole.

To spell it out:
WRONG:
document.getElementById('personal_details').style. display='none';

RIGHT:
document.getElementById('personal_details').style.display='none';
(mind the missing space after style.)

The other 3 lines also have a space.
I leave that as an exercise for you to find them...

Well, it is hard to tell how this code is called.
Where and how is switchMenu() called?
What is the id passed to switchMenu()?

How does the HTML look?

Try to post a minimal example that *doesn't work* as you expected,
including your HTML, and relevant CSS definitions (if any).

Also: try to do it yourself first by looking at the errorconsole.
I advise you to use Firefox for this: tools -> Error Console.
All errors will appear there.

Hi Sam

I have used your first method. But it keeps on expanding and
collapsing the menu till the mouse is over the image.What I need is
the menu should expand when the mouse is over the + image and it
should collapse when the mouse is taken off the image. But the menu
keeps on collapsing and expanding once the mouse is over the +
image.It does not stops for the user to click on the menu item.

This isn't true. The line that you have labelled "WRONG" is fine
(syntactically). javascript is very tolerant of white space in its
source code, allowing any number of space characters, carriage
returns, etc., to appear in almost any context. The above, for
example, could be written as:-

document
..
getElementById
(
'personal_details'
)
..
style
..
display
=
'none'
;

- and still be syntactically correct javascript source code. Obviously
there is a question of the wisdom of doing anything like that as the
result was a significant drop in the readability of the code. And in
your "WRONG" example the inconsistency of having an arbitrary space
character after just one of the dot operators is not adding to the
readability of the result.
The other 3 lines also have a space.
I leave that as an exercise for you to find them...

And the additional space characters in those three lines will result
in syntax errors and so should be looked at.

Thanks Richard,

As you may have guessed I wasn't aware of that.
I stand corrected.

To be honest: I dislike the fact that JavaScript is so tollerant.

Let me explain my problem in detail.I have a three level menu like
this:

[+]level 1
[+]level 11
[+]level 12
[-]level 13
level 131
level 132
level 133
[+]level 2

and so on.

I want to make the above menu using html and javascript and I dont
know javascript at all.I found the below javascript for expand/
collapse menu on net.

<script type="text/javascript">
document.getElementById('level_1').style.display='none';
document.getElementById('level_2').style.display='none';
document.getElementById('level_3').style.display='none';
document.getElementById('level_4').style.display='none';

function switchMenu(id)
{
obj=document.getElementById(id);
col=document.getElementById("x" + id);
if (obj.style.display=='none')
{
obj.style.display='block';
col.innerHTML="<img src='/it_media/v4/n/images/minus2.gif'/>";

}
else
{
obj.style.display='none';
col.innerHTML="<img src='/it_media/v4/n/images/plus2.gif'/>";

}
}
</script>

While using this script i found that when user clicks on level 1 [+]
image, the menu collapses, but what I want is the menu should collpase
on onmouseover and expand on onmouseout.


and my HTML code is like this:

<div class="menu" onmouseover="switchMenu('level_1');"
onmouseout="switchMenu('level_1');">
<div id="xlevel_1">
<img src='/it_media/v4/n/images/plus2.gif'/>
level 1
</div>
<div id="level_1">
<div id="xlevel_11">
<img src='/it_media/v4/n/images/plus2.gif'/>
level 11
</div>
<div id="level_11">
<ul>
<li class="item">
<a href="url" title=" ">level 111</
a>
</li>
<li class="item">
<a href="url" title=" ">level 112</a>
</li>
</ul>
</div>
</div>

Ok

now i have changed the javascript function switchMenu into two
functions which are as follows:

<script type="text/javascript">
document.getElementById
('personal_details').style.display='block';
document.getElementById
('income_details').style.display='block';
document.getElementById
('return_details').style.display='block';
document.getElementById
('filing_details').style.display='block';
document.getElementById
('aboutyou').style.display='block';
document.getElementById
('otherdetail').style.display='block';
document.getElementById
('income').style.display='block';
document.getElementById
('deductions').style.display='block';
document.getElementById
('relief').style.display='block';
document.getElementById
('taxes').style.display='block';
document.getElementById

</script>

But the problem now is when I bring mouseout from first level the menu
collpases and i am not able to select the secondlevel menu. i.e
after taking mouse away from level 1, I am not able to select level 11
as leve 1 collapses.

Please read my earlier post before answering the query.

where is your html code
we don't know how you try to use the script(s)
Not understood,
if the menu is hidden when you leave the [-] image
how do you expect the user could click one of the links ?
But the menu
keeps on collapsing and expanding once the mouse is over the +
image.It does not stops for the user to click on the menu item.
mouseover and out to put(drag) in the IMG ?

Let me explain my problem in detail.I have a three level menu like
this:

[+]level 1
     [+]level 11
     [+]level 12
     [-]level 13
          level 131
          level 132
          level 133
[+]level 2

and so on.

I want to make the above menu using html and javascript and I dont
know javascript at all.I found the below javascript for expand/
collapse menu on net.

<script type="text/javascript">
document.getElementById('level_1').style.display='none';
document.getElementById('level_2').style.display='none';
document.getElementById('level_3').style.display='none';
document.getElementById('level_4').style.display='none';

function switchMenu(id)
{
obj=document.getElementById(id);
col=document.getElementById("x" + id);
if (obj.style.display=='none')
{
obj.style.display='block';
col.innerHTML="<img src='/it_media/v4/n/images/minus2.gif'/>";

}

else
{
obj.style.display='none';
col.innerHTML="<img src='/it_media/v4/n/images/plus2.gif'/>";

}
}

</script>

While using this script i found that when user clicks on level 1 [+]
image, the menu collapses, but what I want is the menu should collpase
on onmouseover and expand on onmouseout.

and my HTML code is like this:

<div class="menu" onmouseover="switchMenu('level_1');"
onmouseout="switchMenu('level_1');">
   <div id="xlevel_1">
      <img src='/it_media/v4/n/images/plus2.gif'/>
      level 1
   </div>
   <div id="level_1">
             <div id="xlevel_11">
               <img src='/it_media/v4/n/images/plus2.gif'/>
                 level 11
            </div>
           <div id="level_11">
           <ul>
                <li class="item">
                    <a href="url" title=" ">level111</
a>
               </li>
               <li class="item">
                    <a href="url" title=" ">level112</a>
                </li>
            </ul>
         </div>
     </div>
