<h2 class="first">Building trees from HTML markup or from previous definitions.</h2>
|
|
|
|
<p>In this brief example for the <a href="http://developer.yahoo.com/yui/treeview/">TreeView Control</a>,
|
|
we begin with a <code><div></code> containing a set of nested unordered lists <code><ul></code>
|
|
providing the basic tree structure</p>
|
|
|
|
<textarea name="code" class="JScript" cols="60" rows="1"><div id="markup">
|
|
<ul>
|
|
<li>List 0
|
|
<ul>
|
|
<li>List 0-0
|
|
<ul>
|
|
<li>item 0-0-0</li>
|
|
<li>item 0-0-1</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
</li>
|
|
<li>item 0-1
|
|
<ul>
|
|
<li><a target="_new" href="HTTP://developer.yahoo.com/yui" title="go to YUI Home Page">YUI</a>
|
|
<ul>
|
|
<li>item 0-1-0</li>
|
|
<li>item 0-1-1</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
</div></textarea>
|
|
|
|
<p>We create a new TreeView and render it. The TreeView will read the existing HTML and build the nodes from it.</p>
|
|
|
|
<textarea name="code" class="JScript" cols="60" rows="1">tree1 = new YAHOO.widget.TreeView("markup");
|
|
tree1.render();</textarea>
|
|
|
|
<p>Once we have a tree, we can read its definition, preserve it somehow and then build an identical tree from it.
|
|
In the second part we are building a couple of trees, one identical to the full tree
|
|
and another one from just a branch of it</p>
|
|
|
|
<textarea name="code" class="JScript" cols="60" rows="1">tree2 = new YAHOO.widget.TreeView("treeDiv2", tree1.getTreeDefinition());
|
|
tree2.render();
|
|
|
|
var branch = tree1.getRoot().children[1];
|
|
tree3 = new YAHOO.widget.TreeView("treeDiv3", branch.getNodeDefinition());
|
|
tree3.render();
|
|
</textarea>
|
|
<p>For <code>tree2</code> we have used the full tree definition from the first tree.
|
|
For <code>tree3</code> we have first located a branch, for this sample, the second branch from the root
|
|
and used its definition for the tree</p>
|
|
|
|
<p>Finally, in the last tree, we used an object literal to define the full tree.</p>
|
|
|
|
|
|
<textarea name="code" class="JScript" cols="60" rows="1">(new YAHOO.widget.TreeView("treeDiv4",[
|
|
'Label 0',
|
|
{type:'Text', label:'text label 1', title:'this is the tooltip for text label 1'},
|
|
{type:'Text', label:'branch 1', title:'there should be children here', expanded:true, children:[
|
|
'Label 1-0'
|
|
]},
|
|
{type:'Text',label:'YAHOO',title:'this should be an href', href:'http://www.yahoo.com', target:'somewhere new'},
|
|
{type:'HTML',html:'<a href="developer.yahoo.com/yui">YUI</a>'},
|
|
{type:'MenuNode',label:'branch 3',title:'this is a menu node', expanded:false, children:[
|
|
'Label 3-0',
|
|
'Label 3-1'
|
|
]}
|
|
])).render();
|
|
</textarea>
|
|
|
|
<p>Here we provide as a second argument to the constructor an array where each item can be either an
|
|
object literal or a simple string, such as <code>'Label 0'</code>,
|
|
which will be converted to a simple TextNode.</p>
|
|
<p>The items in the array can also be objects containing more detailed definitions for each node.
|
|
All require a <code>type</code> property using either a short-name such as <code>'Text'</code> or <code>'HTML'</code> (case-insensitive)
|
|
or the object name of the node type like <code>'MenuNode'</code>, which will be resolved to YAHOO.widget.MenuNode.</p>
|
|
<p>Object definitions allow precise control over the tree since any public property of each node can be specified,
|
|
for example, some nodes start expanded while others collapsed. We cannot have such expressiveness from plain HTML markup.</p>
|
|
<p>We have defined a couple of external links. In the first one, labeled <code>YAHOO</code>, the link has the
|
|
generic style of the rest of the nodes in the tree. In the second one, labeled <code>YUI</code>, we have used an HTMLNode
|
|
instead of a TextNode so TreeView copies that string into the node without adding further classNames so it gets a different look.</p>
|
|
<p>The last node, being a MenuNode, forces other branches to collapse when expanded. The other node with children, being a plain node
|
|
doesn't mind if other nodes remain expanded.</p>
|
|
<p>Nodes may contain a <code>children</code> property containing further node definitions.</p> </div>
