Recent Questions Javascript Tree View Fallback
Q: It's been couple of months since I last time asked something about tree menu. I am still evaluating the software.
I have a short question. Is it possible to use CSS instead of JavaScript to tune the look and feel of the tree menu? For example I would be interested in giving menu css java item height value in relative numbers (em or %) rather than specifying a size in pixels...
A: But actually you can use 'em' and '%' units in Javascript/DHTML Tree, forexample.
var tmenuWidth="13em";
var tmenuHeight="12em";
var tmenuWidth="35%";
var tmenuHeight="15em";
Q: Is there a way to programmatically close a hover popup via javascript?
A: You can close the popup using the following function:document.getElementById('win').hide();
Unfortunately it won't work if you use iframe as window content.
You open another page in the popup (in Iframe) so you cannot access
document.getElementById('win').hide();
element which is situated on the first page.
When you use text or object_id as window content the content of the popup will be situated
on the same page so you can access document.getElementById('win') element and hide it.
There is a workaround for Iframe.
Use text as content type and add the following code inside popup:
<a onclick="document.getElementById('win').hide();">...</a> <iframe></iframe>Q: 1) is it possible to have multiple(different) images, popup menus?
2) Can it Automatically popup instead of Left click?
Would you show me How?
3) What is: menuInd - index of the javascript menu script on a page, >= 0 ?
Could you give more explanation?
A: > 1) is it possible to have multiple(different) images, popup menus?
Yes, you can use any number of popup menus on your page.
> 2) Can it Automatically popup instead of Left click?
> Would you show me How?
You can use onMouseOver event instead of onClick or onContextMenu events in that case.
> 3) What is: menuInd - index of the javascript menu script on a page, >= 0 ?
Each menu has ID. The ID's number starts with 0.
So, when you have several data files on your page you have such ID's:
<script type="text/javascript" language="JavaScript1.2" src="menu-top.js"></script> // ID - 0 //standard menu (doesn't use popup feature)
<script type="text/javascript" language="JavaScript1.2" src="source_pop.js"></script> // ID - 1
<script type="text/javascript" language="JavaScript1.2" src="source_pop1.js"></script> // ID - 2
<script type="text/javascript" language="JavaScript1.2" src="source_pop2.js"></script> // ID - 3
<script type="text/javascript" language="JavaScript1.2" src="source_pop3.js"></script> // ID - 4
and so on.
If you want to have different Popup menus (there color, item, text,font and so on) you should create different .js files with yourparameters. And call them from your page, for example:
<script type="text/javascript" language="JavaScript1.2" src="menu-top.js"></script>
<SCRIPT language=JavaScript1.2 src="source_pop.js" type=text/javascript></SCRIPT>
<SCRIPT language=JavaScript1.2 src="source_pop1.js" type=text/javascript></SCRIPT>
<SCRIPT language=JavaScript1.2 src="source_pop2.js" type=text/javascript></SCRIPT>
<SCRIPT language=JavaScript1.2 src="source_pop3.js" type=text/javascript></SCRIPT>
If you have different item text only you can use one
<SCRIPT language=JavaScript1.2 src="source_pop.js" type=text/javascript></SCRIPT>
file. But you should delete the following code:
var menuItems = [
["Next","testlink.htm"],
["Prev","testlink.htm"],
["Close","testlink.htm"],
];
dm_init();
and move it to the html page:
<body>
...
<SCRIPT language=JavaScript1.2 src="source_pop.js" type=text/javascript></SCRIPT>
<script type="text/javascript"> //first popup menu ID - 1
var menuItems = [
["Next","testlink.htm"],
["Prev","testlink.htm"],
["Close","testlink.htm"],
];
dm_init();
</SCRIPT>
<script type="text/javascript"> //second popup menu ID - 2
var menuItems = [
["Text","testlink.htm"],
["Text1","testlink.htm"],
["Text2","testlink.htm"],
];
dm_init();
</SCRIPT>
<script type="text/javascript"> //third popup menu ID - 3
var menuItems = [
["New_Text","testlink.htm"],
["New_Text1","testlink.htm"],
["New_Text2","testlink.htm"],
];
dm_init();
</SCRIPT>
<script type="text/javascript"> //fourth popup menu ID - 4
var menuItems = [
["New","testlink.htm"],
["New","testlink.htm"],
["New","testlink.htm"],
];
dm_init();
</SCRIPT>
<img src="testimage.gif" width=200 onClick="return dm_popup(1, 1000, event);" style="cursor: hand;">
<img src="testimage.gif" width=200 onClick="return dm_popup(2, 1000, event);" style="cursor: hand;">
<img src="testimage.gif" width=200 onClick="return dm_popup(3, 1000, event);" style="cursor: hand;">
<img src="testimage.gif" width=200 onClick="return dm_popup(4, 1000, event);" style="cursor: hand;">
</body>
Q: Hi, I am testing your menu system for my company and would like to know how to keep the menu in the centre of the page like <centre></centre>.
I know how to do it without a floating menu but cannot work out how to do this with it floating.
A: When you use floatable menu you can't use relative menu position.
So, if you use
var absolutePos = 0;
and to center the menu you use <p> or <div> with the center alignment your menu won't float.
To center your floatable menu you should set absolute coordinates.
