There are limitations to the styles that can be - * associated with a row (such as you can't assign a border--well 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 - * dragHandle - * This is the name of a class that you assign to one or more cells in each row that is draggable. If you - * specify this class, then you are responsible for setting cursor: move in the CSS and only these cells - * will have the drag behaviour. If you do not specify a dragHandle, then you get the old behaviour where - * the whole row is draggable. - * - * 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. - * - * Other methods: - * - * $("...").tableDnDUpdate() - * Will update all the matching tables, that is it will reapply the mousedown method to the rows (or handle cells). - * This is useful if you have updated the table rows using Ajax and you want to make the table draggable again. - * The table maintains the original configuration (so you don't have to specify it again). - * - * $("...").tableDnDSerialize() - * Will serialize and return the serialized string as above, but for each of the matching tables--so it can be - * called from anywhere and isn't dependent on the currentTable being set up correctly before calling - * - * Known problems: - * - Auto-scoll has some problems with IE7 (it scrolls even when it shouldn't), work-around: set scrollAmount to 0 - * - * Version 0.2: 2008-02-20 First public version - * Version 0.3: 2008-02-07 Added onDragStart option - * Made the scroll amount configurable (default is 5 as before) - * Version 0.4: 2008-03-15 Changed the noDrag/noDrop attributes to nodrag/nodrop classes - * Added onAllowDrop to control dropping - * Fixed a bug which meant that you couldn't set the scroll amount in both directions - * Added serialize method - * Version 0.5: 2008-05-16 Changed so that if you specify a dragHandle class it doesn't make the whole row - * draggable - * Improved the serialize method to use a default (and settable) regular expression. - * Added tableDnDupate() and tableDnDSerialize() to be called when you are outside the table - */ -jQuery.tableDnD = { - /** Keep hold of the current table being dragged */ - currentTable : null, - /** Keep hold of the current drag object if any */ - dragObject: null, - /** The current mouse offset */ - mouseOffset: null, - /** Remember the old value of Y so that we don't do too much processing */ - oldY: 0, - - /** Actually build the structure */ - build: function(options) { - // Set up the defaults if any - - this.each(function() { - // This is bound to each matching table, set up the defaults and override with user options - this.tableDnDConfig = jQuery.extend({ - onDragStyle: null, - onDropStyle: null, - // Add in the default class for whileDragging - onDragClass: "tDnD_whileDrag", - onDrop: null, - onDragStart: null, - scrollAmount: 5, - serializeRegexp: /[^\-]*$/, // The regular expression to use to trim row IDs - serializeParamName: null, // If you want to specify another parameter name instead of the table ID - dragHandle: null // If you give the name of a class here, then only Cells with this class will be draggable - }, options || {}); - // Now make the rows draggable - jQuery.tableDnD.makeDraggable(this); - }); - - // Now we need to capture the mouse up and mouse move event - // We can use bind so that we don't interfere with other event handlers - jQuery(document) - .bind('mousemove', jQuery.tableDnD.mousemove) - .bind('mouseup', jQuery.tableDnD.mouseup); - - // Don't break the chain - return this; - }, - - /** This function makes all the rows on the table draggable apart from those marked as "NoDrag" */ - makeDraggable: function(table) { - var config = table.tableDnDConfig; - if (table.tableDnDConfig.dragHandle) { - // We only need to add the event to the specified cells - var cells = jQuery("td."+table.tableDnDConfig.dragHandle, table); - cells.each(function() { - // The cell is bound to "this" - jQuery(this).mousedown(function(ev) { - jQuery.tableDnD.dragObject = this.parentNode; - jQuery.tableDnD.currentTable = table; - jQuery.tableDnD.mouseOffset = jQuery.tableDnD.getMouseOffset(this, ev); - if (config.onDragStart) { - // Call the onDrop method if there is one - config.onDragStart(table, this); - } - return false; - }); - }) - } else { - // For backwards compatibility, we add the event to the whole row - var rows = jQuery("tr", table); // get all the rows as a wrapped set - rows.each(function() { - // Iterate through each row, the row is bound to "this" - var row = jQuery(this); - if (!
