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: Is it possible to add a combo box or a search field to a tree view component?
A: You can paste any html code inside item's text, for example:
["+Support", "", "icon5_t.gif", "icon5_to.gif", "", "Support Tip"],
["|Index <select style='width:120px;height:17px;font:normal 10px Tahoma,Arial;'><option>Section 1<option>Section 2<option>Section 3</select>","", "", "", "", "", "", "0"],
["|Search <input type=text style='width:80px;height:17px;font:normal 10px Tahoma,Arial;'> <input type=button value='Go'style='width:30px;height:17px;font:normal 10px Tahoma,Arial;'>", "", "", "", "", "", "", "0"],
["|Write Us", "mailto:[email protected]", ""],
["|<INPUT TYPE=checkbox CHECKED ID=chk1 onclick='choosebox1()'>Uncheck this check box for some free advice","","","",],
["<img src='img/sep.gif' width=113 height=1>"],
Q: When I maximize the screen the popup windows appear to open below taskbar.
Is there a setting to correct this so that windows always appear above the cascading navigation bar?
A: You should set the following parameter to show submenus above the top items:
var subMenuVAlign="bottom";
But notice that if there will be no enough space above the menu your submenus will be
shown under the menu.Q: I was wondering if you could help me. I have recently done a site and put a menu into the site
The basic javascript menu is on the top of the screen but it has lines through each of the menus just after the words and before the arrow on each of them. I have stretched the menu out to cover the whole of the top of the page but i need to get these lines out of the menu.
Can you please help me with this problem?
A: See images in Vista Templates have the fixed width and height (92 x 21):
var itemStyles = [
["itemWidth=92px","itemHeight=21px","itemBackColor=transparent,transparent","itemBorderWidth=0","fontStyle=normal 11pxTahoma","fontColor=#3A3A3A,#000000","itemBackImage=data-vista-2-04.files/btn_olive.gif,data-vista-2-04.files/btn_white.gif"],
];
When items text is too long you can have such effect.
You can try to use combined background for your items, for example:
var beforeItemImage = [,]; //left-side image for normal and mouse over state
var itemBackImage = [,]; //background or image for normal and mouse over state
var afterItemImage = [,]; //right-side image for normal and mouse over state
var beforeItemImageW = '';
var afterItemImageW = '';
var beforeItemImageH = '';
var afterItemImageH ='';
But you should create a small images in any Graph Editor, for example:
button_n_back.gif
button_n_left.gif
button_n_right.gif
button_o_back.gif
button_o_left.gif
button_o_right.gif
