How to save current Vim structural configuration across sessions?

How to save current Vim structural configuration across sessions?

pBy 'structural configuration' I mean the current open buffers, tabs,
windows, and their positions./p pBy 'across sessions' means that I want to
be able to type code:save/code, have it save to code~/.vimsconf/code, and
have typing code:load/code actually load those buffers and set up the
windows and tabs as they were before, for example./p pIs there maybe built
in functionality for that? Or maybe a plugin?/p pI'm using openSUSE 12.3/p

Using jQuery to switch to a tab with a validation error

Using jQuery to switch to a tab with a validation error

I'm trying to get jQuery to switch to a tab if it finds an error on it.
Right now it will find an error but won't go to the tab with the error.
This is the code I currently have
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('#Form').validate({
ignore: ".ignore",
invalidHandler: function(){
jQuery("#tabs").tabs("select", jQuery("#Form
.input-validation-error").closest(".tab-pane").get(0).id);
}
});
});
jQuery('.Submit').click(function(evt) {
evt.preventDefault();
jQuery('#Form').submit()
});
</script>
Thanks for any responses

Finding rules for two functions

Finding rules for two functions

What are rules for $\alpha(\Delta x, \Delta y) , \beta(\Delta x, \Delta
y)$ functions so that $f(x,y)=\mathrm{e}^{xy}$ to be differentiable on
$\mathbb{R}^2$ by the following definition?
$\textbf{DEFINITION}$: Suppose that for every point $(a+\Delta x, b+\Delta
y)$ in a deleted neighborhood of $(a,b)$ we can write: $f(a+\Delta x,
b+\Delta y)-f(a,b)=A\Delta x+\Delta y +\alpha(\Delta x, \Delta y)\Delta
x+\beta(\Delta x, \Delta y)\Delta y$ where $A,B$ are constant, and
$\alpha(\Delta x, \Delta y) , \beta(\Delta x, \Delta y)$ are functions of
$\Delta x, \Delta y$ such that $\displaystyle\lim_{(\Delta x, \Delta y)\to
(0,0)}\alpha(\Delta x, \Delta y) =\lim_{(\Delta x, \Delta y)\to
(0,0)}\beta(\Delta x, \Delta y) =0 $, then $f$ is said to be
$\underline{differentiable}$ at $(a,b)$.
$\textbf{Remark}$: We should be find $A,B$ , and functions $\alpha(\Delta
x, \Delta y) , \beta(\Delta x, \Delta y)$ at any point $(a, b)$ . Of
course I know that $A=\dfrac{\partial f}{\partial x}(a,b) \ , \
B=\dfrac{\partial f}{\partial y}(a,b)$ . But What are $\alpha(\Delta x,
\Delta y) , \beta(\Delta x, \Delta y)$ functions, exactly?

jQuery Nested Sortable in Codeigniter

jQuery Nested Sortable in Codeigniter

I have adapted the nested sortable plugin to codeigniter, its updating the
order records in the database, but while i'm getting the all pages, its
not ordering in user interface, just ordering according to id there. I
have a get function in MY_Model, which is doing well, and ordering
everything else in the other pages, but only this one is lacking.
Order Controllers :
public function order ()
{
$this->data['sortable'] = TRUE;
$this->data['subview'] = 'admin/page/order';
$this->load->view('admin/_layout_main', $this->data);
}
public function order_ajax ()
{
// Save order from ajax call
if (isset($_POST['sortable'])) {
$this->page_m->save_order($_POST['sortable']);
}
// Fetch all pages
$this->data['pages'] = $this->page_m->get_nested();
// Load view
$this->load->view('admin/page/order_ajax', $this->data);
}
Order Model Functions:
public function save_order ($pages)
{
if (count($pages)) {
foreach ($pages as $order => $page) {
if ($page['item_id'] != '') {
$data = array('parent_id' => (int) $page['parent_id'],
'order' => $order);
$this->db->set($data)->where($this->_primary_key,
$page['item_id'])->update($this->_table_name);
}
}
}
}
public function get_nested ()
{
$pages = $this->db->get('pages')->result_array();
$array = array();
foreach ($pages as $page) {
if (! $page['parent_id']) {
$array[$page['id']] = $page;
}
else {
$array[$page['parent_id']]['children'][] = $page;
}
}
return $array;
}
Order Pages View :
<section>
<h2>Order Pages</h2>
<p class="alert alert-info">Hit the save, after you are done</p>
<div id="orderResult"></div>
<input type="button" id="save" value="Save" class="btn btn-primary" />
</section>
<script>
$(function() {
$.post('<?php echo site_url('admin/page/order_ajax'); ?>', {},
function(data){
$('#orderResult').html(data);
});
$('#save').click(function(){
oSortable = $('.sortable').nestedSortable('toArray');
$('#orderResult').slideUp(function(){
$.post('<?php echo site_url('admin/page/order_ajax'); ?>', {
sortable: oSortable }, function(data){
$('#orderResult').html(data);
$('#orderResult').slideDown();
});
});
});
});
</script>
Order Ajax View :
echo get_ol($pages);
function get_ol ($pages, $child = FALSE)
{
$str = '';
if (count($pages)) {
$str .= $child == FALSE ? '<ol class="sortable">' : '<ol>';
foreach ($pages as $page) {
#dump($item);
$str .= '<li id="list_' . $page['id'] .'">';
$str .= '<div>' . $page['title'] .'</div>';
// Do we have any children?
if (isset($page['children']) && count($page['children'])) {
$str .= get_ol($page['children'], TRUE);
}
$str .= '</li>' . PHP_EOL;
}
$str .= '</ol>' . PHP_EOL;
}
return $str;
}
?>
<script>
$(document).ready(function(){
$('.sortable').nestedSortable({
handle: 'div',
items: 'li',
toleranceElement: '> div',
maxLevels: 2
});
});
</script>
Thanks
