Is it possible find a node backwards instead of forwards.
I would like to do (remember find_reverse does not exist)
I'm using jsTree-0.9.9a. As a test this is the code i'm using to display the ID
oncreate: function(NODE, REF_NODE, TYPE, TREE_OBJ, RB)
{
if (TYPE === "inside") {
parent_id = $(REF_NODE).attr('id');
alert(parent_id)
}}
This works fine when the parent has no child nodes, however, when a child node exists nothing is returned.
why I cannot access json data by using a variable as a node name. I'm trying to grab a random quote from a .json file and display it in a div. When I access a node in the object by node name I can access the node data. However, when I try to use a variable in place of the node name (because I want to grab a random node) I get an object undefined error.
JSON object:
{
"quote1" : {"quote" : "hello, world."},
"quote2" : {"quote" : "goodbye, world."},
"quote3" : {"quote" : "out of this world."}

I am writing a programmatically control the focus (basically what I want is to transform "tab" to "enter")... why do I want such a non standard thing? Customer request... and since he is paying, I have to implement it.
Now, currently I solved the problem by finding the next element with a greater "tabIndex" value, but that forces me to configure tabIndex values for everything in my form... and that is specially problematic because some of my UIs are generated dynamically with information in the database...
So, what I want, is to find the next ":input" element traversing the DOM tree in the same way the focus moves when pressing the "tab" key... that should be something like "find the next sibling that is ":input"... if none found, go to parent node, got to sibling of parent node, look in there... if none found, and this parent has no next sibling, go to the parent of the parent and repeat operation recursively..
is there (somewhere) a jQuery plugin (or method) that already does this? Or do I need to write it?

i'm trying check the value for a node that is loaded with ajax, and to check it every certain time (3 seconds). I've come this far, but don't know where to go from here:

How to handle error in .find() if nothing found in XML nodes
What I mean is: I request for XML file :
$.ajax({
type:"GET",
url:"myXmlFileOnServer.xml",
dataType: "xml",
[Code].....
so nothing happens at all (after request is done (NO problem with request) - 200 OK )
I've got a semantic XML document, for which I'm using $.get successfully to extract <title> and description> nodes. The <link> node does not work, however. It returns blank. Strange, since I can see in Firebug that $(this) has 4 children, and link is in there.

within a function for an onchange-handler ($(...).change(function(e) {...) i tried something like:
$(":parent input[name^=subsequentProperty]", this);
this does not work, but:
$("input[name^=subsequentProperty]", this.parentNode);
does work.
I want to remove the class-attribute of all <a>-tags in this table-tr:
In addOrder, I want to use removeClass("back_blue_3").removeClass("back_blue_2") of all <a> in this tr.
I tryed this:
But this causes just an error.
How I have to handle it?
Suppose I have <div id="outter"element. In side the div, I have
other <divand <imgelements. I used the following code
insideElementsList = outterDiv.childNodes;
for (var i = 0; i < list.length; i ++){
insideElementList[i] ...
}
In the loop, how can I know the current element is a <divor a <img>?
What I am coding now is a piece of a much larger project that I am, for the moment, developing on my own. This code, relatively useless on its own, is essentially practice or proof -of-concept. Much of it will probably be used in the larger project. If at times, it seems that I am using a cannon to kill a fly, this is why.
Additionally, I do not claim credit for all the code here. Some of it is copied from other sources. I have studied it, understood it , then modified it appropriately, making it my own.
However, the code is broken. I have tested it on Internet Explorer 9.0.??? and Firefox 4.0.1. It breaks in both browsers. I have previously tested it in Chrome, but not recently. On IE I have used the built in debugger, and I have been using Firebug in Firefox. I have also used the debugger at [URL] quite frequently. JSLINT returns some 'Bad Type' errors regarding 12 lines in the html body, each having the structure: <td><input /></td>. I can find no explanation for the 'Bad Type' errors. Otherwise, according to JSLINT, the code is fine.
The predecessor to this code worked fine. I had been using inline event handlers (onblur and oninput) that called the doMath function when one enters data into the table. The values are then averaged and summed. All this is extremely basic. The problem began when I removed the inline event handlers and began to use window.onload (I believe I am using document.onload now, but the problem has not changed.)
I have adopted Douglas Crockford's 'walkTheDom' recursive function to find all tags with a particular class name. I would like to assign every element in the array returned by this function an event handler.
This is the problem: This script simply cannot find the body node of the DOM ( and, seemingly, none of its child nodes either). Initially I tried 'document.body', which failed. I then began with 'this' (essentially 'document') and tried walking the DOM to get to it ('body') eventually. This, too, failed. I tried array index notation to refer to it(I forget the specific syntax), and most recently, I've given it ('body') an id and referred to it directly using 'document.getElementById()'. These most recent attempts also failed.
After hours of figuratively bashing my head against the wall looking at code and probably even more time doing research online, I am extremely frustrated. As often seems to be the case, my problem is probably simple
I have included most of the code, even though it is a little long. This way you may easily copy the code and reproduce the problem yourself. I do not often post to forums, and, more relevant, I have no idea where the error may be located.
Potential problem areas are in RED.

So it will produce a sub-menu with other jQuery that I worked out. So, what I am trying to figure out is when you click on "Project 003" I want JavaScript (or jQuery) to find what menu-item it belongs to, so in this case "#mi". I know I have to go 2 parents up (li, li), but I can't figure out how to get back down into the anchor to use the .attrib('href') function.
