Q: I try to use the javascript menu popups to show an image; then when the mouse is over the image I dynamically generate a panel of http links. It works perfectly, but the problem is that I would like to do the same with several images (for instance 2) and different links : I'm not able to do that, whether I change the value of menuItems var or not, I display the same link values on both images (it seems menuItems is a global var and can be set only once).
Have you heard about this problem and could you give me a solution (this is a bit urgent, I have sold this solution to my customers) ?
A: See how you should call dm_popup() functions:
<img src="../../../../fileadmin/img/flag_de.gif" width="50" onMouseOver="return dm_popup(0, 2000, event);" style="cursor: pointer;">
// 0 - is ID of the first menu
....
<img src="../../../../fileadmin/img/flag_fr.gif" width="50" onMouseOver="return dm_popup(1, 2000, event);" style="cursor: pointer;">
// 1 - is ID of the second menu
// 2 - is ID of the third menu
... and so on.
Q: The only remaining problem I see is that the html popup menu appears in slightly different positions depending upon where your mouse touches the icon.
Is there a way to make the menu position absolute in respect to the icon? I have tried playing with the menu item parameters that seemed related with no success.
A: See dm_popup() function parameters:
return dm_popup(menuInd, pause, event, x, y)
menuInd - index of the menu on a page, >= 0.
pause - determines the time when the html popup menu will be hidden.
event - constant. Do not change.
x, y - optional. Set these parameters if you want the menu to appear in the specified place.
In other case the menu will be shown in the mouse position.
Q: I am having some difficulty dynamically adding items to a tree javascript and menu.
I have a menu with one "root" item. I see the use of the "+" symbol within the item name. I do not see any documentation regarding this symbol, only "|". Can you explain?
If I have one menu with this one "root" node, how would I add an subitem to this root node?
Here is my code so far, but the inserted items appear to be at the same level as the root node.
var rootItem = dtreet_ext_getItemIDByIndex ( 0,0 );
var menuItem = new Array(10);
for ( var i = 0; i < producers.length; i++ )
{
var producer = producers[ i ];
menuItem[0] = producer.name;
dtreet_ext_insertItem ( 0, 0, i + 1, menuItem );
A: See dtreet_ext_insertItem () function has the following parameters:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
Creates a new item and inserts it into a specified position.
menuInd - index of a javascript and menu on a page, >= 0.
parentItemID - ID property of an item.<, >= 0.
itemInd - index of a new item within the javascript and menu, >= 0.
itemParams - item parameters.
Notice that parentItemID is the Id property of the parent item (notindex). If you want to add top items you should set parentItemID=0.
itemInd - you should use this parameter if you want to add item in thespecific place, for example set itemInd=5 if you want to add itembefore the existing item with itemInd=5.
If you set itemInd=null the new item will be added at the end of this submenu and its index will be added automatically.
Q: Javascript menu frame Borders are present Firefox but missing in IE7, IE8, Google Chrome, Safari.
Firefox shows the borders ok.
A: You've set the following parameters in this menu:
var menuBorderColor="#FF9191 #FF7837 #E10000 #952D00 ";
var menuBorderWidth=3;
var menuBorderStyle="";
You should specify style for your border, for example:
var menuBorderStyle="solid";
See the attached example. I cannot notice such issue on Safari forWin. Write what version you're using.
