Answer 1

I made a simple example for you here
Basically, it creates a div over your jstree's one so that it is disabled from user interactions.
I guess you can make it visually better, but i think this gives you the idea.
I also checked that there is no strigth way to disable a jstree, even if it could be usefull.
Maybe you'd want to ask the dev in google group...
HTML Code:
<button id="disable">Disable</button>
<button id="enable">Enable</button>
<div id="jstree-wrapper">
<div id="demo" style="height:100px;">
<ul>
<li id="node_1_id">
<a>Root node 1</a>
<ul>
<li id="child_node_1_id">
<a>Child node 1</a>
</li>
<li id="child_node_2_id">
<a>Child node 2</a>
</li>
</ul>
</li>
</ul>
<ul>
<li><a>Team A's Projects</a>
<ul>
<li><a>Iteration 1</a>
<ul>
<li><a>Story A</a></li>
<li><a>Story B</a></li>
<li><a>Story C</a></li>
</ul>
</li>
<li><a>Iteration 2</a>
<ul>
<li><a>Story D</a></li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
<div id="disabler"></div>
</div>​
CSS code:
#jstree-wrapper {
position: relative;
}
#disabler {
position: absolute;
top: 0px;
left: 0px;
background-color: black;
opacity: 0.5;
}​
JS Code:
$(document).ready(function() {
$("#demo").jstree();
$("#disable").on("click", function() {
$("#disabler").css("width", $("#demo").width());
$("#disabler").css("height", $("#demo").height());
});
$("#enable").on("click", function() {
$("#disabler").css("width", "0px");
$("#disabler").css("height", "0px");
});
});

Here's a very good example I didn't find done so simple and good anywhere else. In this example you can simulate the 'disabled' attribute only by adding CSS style as I entered in the code snippet. It disables by using the CSS "visible:hidden", and adds a translucent mask to cover the whole div area and disable anything inside it. You can choose to comment out the 'Visibility:hidden' to be able to see the elements behind the mask, but then they will be tabable, if you don't mind them hidden then uncomment that style.
function disable(elementId, enabling) {
el = document.getElementById(elementId);
if (enabling) {
el.classList.remove("masked");
} else
{
el.classList.add("masked");
}
}
.masked {
position: relative;
pointer-events: none;
display: inline-block;
//visibility:hidden; /* Uncomment this for complete disabling */
}
.masked::before {
position: absolute;
width: 100%;
height: 100%;
top: 0px;
left: 0px;
visibility: visible;
opacity: 0.2;
background-color: black;
content: "";
}
<button onclick="alert('Now, click \'OK\' then \'Tab\' key to focus next button.\nThen click \'Enter\' to activate it.');">Test</button>
<div id="div1" style="display:inline-block" class="masked">
<button onclick="alert('Sample button was clicked.')">Maskakable</button>
<button onclick="alert('Sample button was clicked.')">Maskakable</button><br/>
<br/>
<button onclick="alert('Sample button was clicked.')">Maskakable</button>
<button onclick="alert('Sample button was clicked.')">Maskakable</button>
</div>
<button>Dummy</button>
<br/>
<br/>
<br/>
<button id="enableBtn" onclick="disable('div1',true);disable('enableBtn',false);disable('disableBtn',true);">Enable</button>
<button id="disableBtn" onclick="disable('div1',false);disable('enableBtn',true);disable('disableBtn',false);" class="masked">Disable</button>
