Ik denk dat het voor ons makkelijker is als we de hele source zien. Dus ook die van alle externe javascripts.

Alle functionaliteit zit in dat .js-bestandjes. Wat daarin staat is interessant, de rest niet.

aha sorry dat wist ik niet in dit bestand heb ik helemaal niets aan gepast. :

code:

 // Arrays for nodes and icons
 var nodes      = new Array();;
 var openNodes  = new Array();
 var icons      = new Array(6);

// Loads all icons that are used in the tree
function preloadIcons() {
    icons[0] = new Image();
    icons[0].src = "img/plus.gif";
    icons[1] = new Image();
    icons[1].src = "img/plusbottom.gif";
    icons[2] = new Image();
    icons[2].src = "img/minus.gif";
    icons[3] = new Image();
    icons[3].src = "img/minusbottom.gif";

    icons[4].src = "img/folder.gif";
    icons[5] = new Image();
    icons[5].src = "img/folderopen.gif";
}
// Create the tree
function createTree(arrName, startNode, openNode) {
    nodes = arrName;
    if (nodes.length > 0) {

Zie deze regel:

code:

document.write("<a href=\"" + nodeValues[3] + "\" onmouseover=\"window.status='" + nodeValues[2] + "';return true;\" onmouseout=\"window.status=' ';return true;\">[img]\"img/folderopen.gif\"[/img]" + nodeValues[2] + "</a><br />");

Daar gaan we nu een target aan toevoegen (hoofdframe was het toch?):

code:

document.write("<a target=\"hoofdframe\" href=\"" + nodeValues[3] + "\" onmouseover=\"window.status='" + nodeValues[2] + "';return true;\" onmouseout=\"window.status=' ';return true;\">[img]\"img/folderopen.gif\"[/img]" + nodeValues[2] + "</a><br />");

Evenzo bij dit stukje code:

code:

1 2	// Start link document.write("<a href=\"" + nodeValues[3] + "\" onmouseover=\"window.status='" + nodeValues[2] + "';return true;\" onmouseout=\"window.status=' ';return true;\">");

Dat wordt dus dit:

code:

1
2

// Start link
document.write("<a target=\"hoofdframe\" href=\"" + nodeValues[3] + "\" onmouseover=\"window.status='" + nodeValues[2] + "';return true;\" onmouseout=\"window.status=' ';return true;\">");

Have fun.
