xAnimation
Using xAnimation is easy. Create an xAnimation object and call one of the animation methods. You can then use the pause/resume methods. The other methods and properties are documented here to help you write your own animation methods. xAnimation provides an animation "engine" which supports unlimited axes of animation, multiple acceleration types and an onEnd handler. The onEnd handler can return true to cause the animation to repeat. It supports a bounce-back feature. Acceleration is implemented as an array of functions so it is easy to add custom acceleration types.

xParaEq
Parametric Equation Animation. X(t) and Y(t) are expressions that generate the x and y coordinates during the slide. These expressions are evaluated with the javascript eval() function. Within the expression you may use any valid sub-expression that eval allows and that is in scope. For example, you may call methods of the Math object such as Math.sin(), Math.cos(), and Math.tan(). You may also reference any global variables or functions. One variable that is within scope for your expression is the parameter t. That is, t is the argument to the equations you provide. At each iteration, the variable t increments by .008 (default value). The Time argument to parametricEquation() specifies the total time for the slide in milliseconds. If the value is zero, the slide will not timeout. You can stop any slide, at any time, by this assignment: element.stop = true;. The values from your expressions are plotted on a coordinate system with it's origin at the center of the sliding element's container. The coordinates are then translated by the element's container's scrollLeft and scrollTop values. So the animation will remain visible if the user scrolls or resizes the element's container.

The border is included, as well as the padding, in the calculations. When returning the existing height, xHeight returns offsetHeight, which is the sum of the border, padding and style.height values. When setting a new height, xHeight finds the current border and padding values of the element and then subtracts those from the height you have specified before assigning the result to style.height.

xResizeTo

xWidth
Return and optionally set the element's width. It attempts to return and/or set the equivalent of offsetWidth. xWidth provides, effectively, a read/write version of offsetWidth. The border is included, as well as the padding, in the calculations. When returning the existing width, xWidth returns offsetWidth, which is the sum of the border, padding and style.width values. When setting a new width, xWidth finds the current border and padding values of the element and then subtracts those from the width you have specified before assigning the result to style.width.

xTableColDisplay
Set the display of a table column.

xTableCursor
Mouseover highlight on rows and cells.

xTableCursor2
Mouseover highlight on rows and cells. Click to select a cell.

xTableHeaderFixed
xTableHeaderFixed is an unobtrusive table enhancement. It makes a copy of a table's THEAD section. While the table is visible in its container the THEAD copy will be fixed to the top of the container, so you can scroll up and down in a long table and the header will always be visible. The container can be a window or a scrollable element. The position and size of the THEAD copy will be adjusted when the window is resized. The THEAD copy is clipped to its container's inner width. You only need to instantiate one xTableHeaderFixed object for each group of tables that have the same styling - and so those tables should have a common className, which you pass to the constructor. You must assign all of the table's styles relative to this className so that the THEAD copy will be styled just like it. It takes the widths of all THs (not TDs) in the THEAD and assigns them to the corresponding THs in the THEAD copy. When instantiating, you do not have to keep a reference to the object - it keeps a reference to itself, but if you plan on calling the 'init' or 'paint' methods later then you'll need to keep a reference to the object.

xTableIterate
Iterates thru all rows and cols of a table and calls fnCallback for each.

xTableRowDisplay
Sets the display of a table row.

xTableSync
Assign a function to handle events which occur on either table and access corresponding TDs.

xBar
Bar-Graph Object

xCalendar
xCalendar is a popup date-picker. It restricts selection to a range of Dates. Days outside the range are greyed-out. Only days in-range have a mouseover effect and can be selected. If you don't set a range it will default to the current year. When the user selects a date, a date string will be assigned to the input element you specify with the 'setInput' method. When the calendar is shown, it is positioned just to the right of this element. While displayed, the user can cancel the calendar by pressing ESCape or clicking anywhere outside the calendar. If you call xCalendar's 'show' method from a click listener then you should call xStopPropagation to prevent xCalendar from being canceled immediately.

xCollapsible
Creates a collapsible list from nested ULs or nested DIVs. A UL/DIV is a "target" - it will have its display toggled when its "trigger" is clicked (except for the outermost UL/DIV). For ULs the trigger is the UL's previous sibling element. For DIVs the trigger is also the DIV's previous sibling element, but it must be a heading element (H1, H2, etc.).

xDialog
Provides a dialog box framework.

xFenster
xFenster takes an existing DIV or IFRAME element and dynamically encloses it in a draggable, resizeable "window" (fenster). If the DIV or IFRAME does not exist xFenster will create it. The constructor takes a single object as an argument. The properties of this object are documented below in the "Parameters" section.

xMenu1
xMenu1 Object Prototype

xMenu1A
xMenu1A Object Prototype. A variation on xMenu1. The menu slides down and up.

xMenu1B
xMenu1B Object Prototype. A variation on xMenu1A. The menu requires a click to close and opening one closes any others that were open.

xMenu5

xMenu6
A UL-based menu with unlimited levels and many other features.

xModalDialog
A simple modal dialog box object.

xPersistentDisplay
xPersistentDisplay provides persistent display or non-display of elements with specific CSS class names.

xPopup
A DHTML alternative to popup windows.

xSelect
Accessible Categories and Sub-Categories. xSelect is another experiment in unobtrusive DHTML. xSelect implements categories and sub-categories as two SELECT controls where the contents of the second control dynamically change depending on the selection in the main control. In your HTML create a SELECT element (which I'll call s0) which contains OPTGROUP elements. Within each OPTGROUP are any number of OPTION elements. Given the id of s0, xSelect creates two SELECT elements: The 'main category' SELECT (s1) contains an OPTION for each OPTGROUP in s0. The 'sub-category' SELECT (s2) is dynamically filled with OPTGROUP OPTIONs depending on which category is selected in s1. s1 and s2 are dynamically created and appended to the same form which contains s0. s0 is hidden, s1 is positioned where s0 was, and s2 is positioned below or to the right of s1. If the browser doesn't support the objects required by xSelect, or if the user has javascript disabled, then the user will get the original SELECT which contains all main categories (as OPTGROUPs) and all sub-categories (as OPTIONs within each OPTGROUP).

xSplitter
This object is a nestable, dual-pane splitter. It can be horizontal or vertical. Each xSplitter has two panes. Pane1 is the left (or top) pane, and pane2 is the right (or bottom) pane. An xSplitter can be nested inside any pane of any other xSplitter. xSplitter makes no assumptions about classnames or id strings - the only requirement is that the xSplitter DIV contain 3 child DIVs in this order: pane1, pane2, and dragBar.

xTabPanelGroup
Downgradeable, accessible, tabbed panels.

xTextArea
A wrapper around an html textarea allowing manipulation of its contents using normal javascript string methods.
