Any link drop down menu

**Unsigned** · 08-26-2005, 03:22 PM

Does anybody know how i would apply a drop down menu from an image flip.
Thanks,

The same way you would for a regular image. There are many ways to do image rollovers (if that is what you are talking about). If the code for the flip or rollover is something like:

Code:

<img src="some1.jpg" onmouseover="flip(this.src, 'some2.jpg')" onmouseout="flip(this.src, 'some1.jpg')">

You can just add the code for the drop down:

Code:

<img src="some1.jpg" onmouseover="flip(this.src, 'some2.jpg');dropdownmenu(this, event, menu1, '150px')" onmouseout="flip(this.src, 'some1.jpg');delayhidemenu()">

As long as the two scripts do not conflict, it will be fine.

Thanks very much for replying, but i'm being a bit thick. I'm using this script for the image flip:

<HEAD>
<script language="JavaScript">
{
ar=new Image();
ar.src="ar.gif";
aron=new Image();
aron.src="aron.gif";

jo=new Image();
jo.src="jo.gif";
joon=new Image();
joon.src="joon.gif";

}

function imageChange(imageID,imageName)
{
document.images[imageID].src=eval(imageName+".src");
}
</script>
</HEAD>

<BODY>
<a href="artists.html" onMouseOver="imageChange('ar','aron')" onMouseOut="imageChange('ar','ar')"><img src="ar.gif" border="0" name="ar"></a>
<a href="join.html" onMouseOver="imageChange('jo','joon')" onMouseOut="imageChange('jo','jo')"><img src="jo.gif" border="0" name="jo"></a>
</BODY>

and this script for the drop menu:

<HEAD>
<style type="text/css">

#dropmenudiv{
position:absolute;
border:1px solid black;
border-bottom-width: 0;
font:normal 12px Verdana;
line-height:18px;
z-index:100;
}

#dropmenudiv a{
width: 100%;
display: block;
text-indent: 3px;
border-bottom: 1px solid black;
padding: 1px 0;
text-decoration: none;
font-weight: bold;
}

#dropmenudiv a:hover{ /*hover background color*/
background-color: yellow;
}

</style>

<script type="text/javascript">

Can i get them to work together?
Thanks.

Either add in the drop down code to the mouse events as shown in my example or create new ones for the image tag:

HTML Code:

<a href="artists.html" onMouseOver="imageChange('ar','aron');dropdownmenu(this, event, menu1, '150px')" onMouseOut="imageChange('ar','ar');delayhidemenu()"><img src="ar.gif" border="0" name="ar"></a>

or:

HTML Code:

<a href="artists.html" onMouseOver="imageChange('ar','aron')" onMouseOut="imageChange('ar','ar')"><img src="ar.gif" onmouseover="dropdownmenu(this, event, menu1, '150px')" onmouseout="delayhidemenu()" border="0" name="ar"></a>

Whichever works best for you.

Brilliant! Thanks very much, that's working fine now.

**Unsigned** · 08-27-2005, 08:38 PM

Sorry, it's me again. The script works fine but i have got a page with alot of tables and ever since i installed the script if i use the back button to that page one of the tables gets larger each time. I can't give you a link to the page as i'm workning offline, but just wondered if you know why this could be.
Thanks again.

**jscheuer1** · 08-28-2005, 12:03 AM

Very hard to tell without seeing it in action. There is a good chance that it is not the script. Take the script off and double check.

**Unsigned** · 08-29-2005, 12:24 AM

Do you know how to change the text colours seperate from the rest of the page as it automatically goes to the text colour i have set in the body.
Thanks again.

**jscheuer1** · 08-29-2005, 02:49 AM

Here is where that is controlled:

Code:

<style type="text/css">

#dropmenudiv{
position:absolute;
border:1px solid black;
border-bottom-width: 0;
font:normal 12px Verdana;
line-height:18px;
z-index:100;
}

#dropmenudiv a{
width: 100%;
display: block;
text-indent: 3px;
border-bottom: 1px solid black;
padding: 1px 0;
text-decoration: none;
font-weight: bold;
}

#dropmenudiv a:hover{ /*hover background color*/
background-color: yellow;
}

</style>

Using valid css style you can add colors to the drop down division. See Blooberry for details or use your favorite css style resource.

I want to let the menu appear to the left and to the right, a bit like this

image (mouseover: menu appears at the left side of the image)
image2 (mouseover: menu appears at the right side of the image)
and so on

does this work, and if its possible, can you help me?^^°
