/**

5
 * quatity of content entered by the user in the box.

/**
16
 * Usage:
17
 *
18
 * From JavaScript, use:
19
 *     $(<node>).TextAreaExpander(<minHeight>, <maxHeight>);
20
 *     where:
21
 *       <node> is the DOM node selector, e.g. "textarea"
22
 *       <minHeight> is the minimum textarea height in pixels (optional)
23
 *       <maxHeight> is the maximum textarea height in pixels (optional)
24
 *
25
 * Alternatively, in you HTML:
26
 *     Assign a class of "expand" to any <textarea> tag.
27
 *     e.g. <textarea name="textarea1" rows="3" cols="40" class="expand"></textarea>
28
 *
29
 *     Or assign a class of "expandMIN-MAX" to set the <textarea> minimum and maximum height.
30
 *     e.g. <textarea name="textarea1" rows="3" cols="40" class="expand50-200"></textarea>
31
 *     The textarea will use an appropriate height between 50 and 200 pixels.

/**
2
 * TableDnD plug-in for JQuery, allows you to drag and drop table rows
3
 * You can set up various options to control how the system will work
4
 * Copyright (c) Denis Howlett <denish@isocra.com>
5
 * Licensed like jQuery, see http://docs.jquery.com/License.
6
 *
7
 * Configuration options:
8
 *
9
 * onDragStyle
10
 *     This is the style that is assigned to the row during drag. There are limitations to the styles that can be
11
 *     associated with a row (such as you can't assign a border--well you can, but it won't be
12
 *     displayed). (So instead consider using onDragClass.) The CSS style to apply is specified as
13
 *     a map (as used in the jQuery css(...) function).
14
 * onDropStyle
15
 *     This is the style that is assigned to the row when it is dropped. As for onDragStyle, there are limitations
16
 *     to what you can do. Also this replaces the original style, so again consider using onDragClass which
17
 *     is simply added and then removed on drop.
18
 * onDragClass
19
 *     This class is added for the duration of the drag and then removed when the row is dropped. It is more
20
 *     flexible than using onDragStyle since it can be inherited by the row cells and other content. The default
21
 *     is class is tDnD_whileDrag. So to use the default, simply customise this CSS class in your
22
 *     stylesheet.
23
 * onDrop
24
 *     Pass a function that will be called when the row is dropped. The function takes 2 parameters: the table
25
 *     and the row that was dropped. You can work out the new order of the rows by using
26
 *     table.rows.
27
 * onDragStart
28
 *     Pass a function that will be called when the user starts dragging. The function takes 2 parameters: the
29
 *     table and the row which the user has started to drag.
30
 * onAllowDrop
31
 *     Pass a function that will be called as a row is over another row. If the function returns true, allow
32
 *     dropping on that row, otherwise not. The function takes 2 parameters: the dragged row and the row under
33
 *     the cursor. It returns a boolean: true allows the drop, false doesn't allow it.
34
 * scrollAmount
35
 *     This is the number of pixels to scroll if the user moves the mouse cursor to the top or bottom of the
36
 *     window. The page should automatically scroll up or down as appropriate (tested in IE6, IE7, Safari, FF2,
37
 *     FF3 beta
38
 * dragHandle
39
 *     This is the name of a class that you assign to one or more cells in each row that is draggable. If you
40
 *     specify this class, then you are responsible for setting cursor: move in the CSS and only these cells
41
 *     will have the drag behaviour. If you do not specify a dragHandle, then you get the old behaviour where
42
 *     the whole row is draggable.
43
 *
44
 * Other ways to control behaviour:
45
 *
46
 * Add class="nodrop" to any rows for which you don't want to allow dropping, and class="nodrag" to any rows
47
 * that you don't want to be draggable.
48
 *
49
 * Inside the onDrop method you can also call $.tableDnD.serialize() this returns a string of the form
50
 * <tableID>[]=<rowID1>&<tableID>[]=<rowID2> so that you can send this back to the server. The table must have
51
 * an ID as must all the rows.
52
 *
53
 * Other methods:
54
 *
55
 * $("...").tableDnDUpdate()
56
 * Will update all the matching tables, that is it will reapply the mousedown method to the rows (or handle cells).
57
 * This is useful if you have updated the table rows using Ajax and you want to make the table draggable again.
58
 * The table maintains the original configuration (so you don't have to specify it again).
59
 *
60
 * $("...").tableDnDSerialize()
61
 * Will serialize and return the serialized string as above, but for each of the matching tables--so it can be
62
 * called from anywhere and isn't dependent on the currentTable being set up correctly before calling
63
 *
64
 * Known problems:
65
 * - Auto-scoll has some problems with IE7  (it scrolls even when it shouldn't), work-around: set scrollAmount to 0
66
 *
67
 * Version 0.2: 2008-02-20 First public version
68
 * Version 0.3: 2008-02-07 Added onDragStart option
69
 *                         Made the scroll amount configurable (default is 5 as before)
70
 * Version 0.4: 2008-03-15 Changed the noDrag/noDrop attributes to nodrag/nodrop classes
71
 *                         Added onAllowDrop to control dropping
72
 *                         Fixed a bug which meant that you couldn't set the scroll amount in both directions
73
 *                         Added serialize method
74
 * Version 0.5: 2008-05-16 Changed so that if you specify a dragHandle class it doesn't make the whole row
75
 *                         draggable
76
 *                         Improved the serialize method to use a default (and settable) regular expression.
77
 *                         Added tableDnDupate() and tableDnDSerialize() to be called when you are outside the table
