-/** |
- * TableDnD plug-in for JQuery, allows you to drag and drop table rows |
- * You can set up various options to control how the system will work |
- * Copyright © Denis Howlett <denish@isocra.com> |
- * Licensed like jQuery, see http://docs.jquery.com/License. |
- * |
- * Configuration options: |
- * |
- * onDragStyle |
- * This is the style that is assigned to the row during drag. There are limitations to the styles that can be |
- * associated with a row (such as you can't assign a borderâwell you can, but it won't be |
- * displayed). (So instead consider using onDragClass.) The CSS style to apply is specified as |
- * a map (as used in the jQuery css(...) function). |
- * onDropStyle |
- * This is the style that is assigned to the row when it is dropped. As for onDragStyle, there are limitations |
- * to what you can do. Also this replaces the original style, so again consider using onDragClass which |
- * is simply added and then removed on drop. |
- * onDragClass |
- * This class is added for the duration of the drag and then removed when the row is dropped. It is more |
- * flexible than using onDragStyle since it can be inherited by the row cells and other content. The default |
- * is class is tDnD_whileDrag. So to use the default, simply customise this CSS class in your |
- * stylesheet. |
- * onDrop |
- * Pass a function that will be called when the row is dropped. The function takes 2 parameters: the table |
- * and the row that was dropped. You can work out the new order of the rows by using |
- * table.rows. |
- * onDragStart |
- * Pass a function that will be called when the user starts dragging. The function takes 2 parameters: the |
- * table and the row which the user has started to drag. |
- * onAllowDrop |
- * Pass a function that will be called as a row is over another row. If the function returns true, allow |
- * dropping on that row, otherwise not. The function takes 2 parameters: the dragged row and the row under |
- * the cursor. It returns a boolean: true allows the drop, false doesn't allow it. |
- * scrollAmount |
- * This is the number of pixels to scroll if the user moves the mouse cursor to the top or bottom of the |
- * window. The page should automatically scroll up or down as appropriate (tested in IE6, IE7, Safari, FF2, |
- * FF3 beta) |
- * |
- * Other ways to control behaviour: |
- * |
- * Add class="nodrop" to any rows for which you don't want to allow dropping, and class="nodrag" to any rows |
- * that you don't want to be draggable. |
- * |
- * Inside the onDrop method you can also call $.tableDnD.serialize() this returns a string of the form |
- * <tableID>[]=<rowID1>&<tableID>[]=<rowID2> so that you can send this back to the server. The table must have |
- * an ID as must all the rows. |
- * |
- * Known problems: |
- * - Auto-scoll has some problems with IE7 (it scrolls even when it shouldn't), work-around: set scrollAmount to 0 |
- * |
- * Version 0.2: 2008-02-20 First public version |
- * Version 0.3: 2008-02-07 Added onDragStart option |
- * Made the scroll amount configurable (default is 5 as before) |
- * Version 0.4: 2008-03-15 Changed the noDrag/noDrop attributes to nodrag/nodrop classes |
- * Added onAllowDrop to control dropping |
- * Fixed a bug which meant that you couldn't set the scroll amount in both directions |
- * Added serialise method |
