You might want to look at  JavaScript HTML DOM Events  for a general overview of events   http   www w3schools com jsref dom obj event asp  PrimeFaces is built on jQuery  so here s jQuery s  Events  documentation   http   api jquery com category events   http   api jquery com category events form-events   http   api jquery com category events keyboard-events   http   api jquery com category events mouse-events   http   api jquery com category events browser-events   Below  I ve listed some of the more common events  with comments about where they can be used  taken from jQuery documentation    Mouse Events   Any HTML element can receive these events    click  dblclick  mousedown  mousemove  mouseover  mouseout  mouseup  Keyboard Events   These events can be attached to any element  but the event is only sent to the element that has the focus  Focusable elements can vary between browsers  but form elements can always get focus so are reasonable candidates for these event types    keydown  keypress  keyup  Form Events  blur  In recent browsers  the domain of the event has been extended to include all element types    change  This event is limited to  lt input gt  elements   lt textarea gt  boxes and  lt select gt  elements    focus  This event is implicitly applicable to a limited set of elements  such as form elements   lt input gt    lt select gt   etc   and links   lt a href gt    In recent browser versions  the event can be extended to include all element types by explicitly setting the element s tabindex property  An element can gain focus via keyboard commands  such as the Tab key  or by mouse clicks on the element    select  This event is limited to  lt input type  text  gt  fields and  lt textarea gt  boxes    submit  It can only be attached to  lt form gt  elements

You can search for  quot Ajax Behavior Events quot  in PrimeFaces User s Guide  and you will find plenty of them for all supported components  That s also what PrimeFaces lead Optimus Prime suggest to do in this related question at the PrimeFaces forum  lt p ajax gt  event list  There is no onblur event  that s the HTML attribute name  but there is a blur event  It s just without the  quot on quot  prefix like as the HTML attribute name  You can also look at all  quot on  quot  attributes of the tag documentation of the component in question to see which are all available  e g   lt p inputText gt

Unfortunatelly  Ajax events are poorly documented and I haven t found any comprehensive list  For example  User Guide v  3 5 lists itemChange event for p autoComplete  but forgets to mention change event   If you want to find out which events are supported    Download and unpack primefaces source jar Find the JavaScript file  where your component is defined  for example  most form components such as SelectOneMenu are defined in forms js  Search for this cfg behaviors references   For example  this section is responsible for launching toggleSelect event in SelectCheckboxMenu component   fireToggleSelectEvent  function checked        if this cfg behaviors            var toggleSelectBehavior   this cfg behaviors  toggleSelect             if toggleSelectBehavior                var ext                     params    name  this id     checked   value  checked                                    toggleSelectBehavior call this  null  ext

As the list of possible events is not tied to p ajax itself but to the component it is used with  you ll have to ask the component for which ajax events it supports   There are multiple ways to determine the ajax events for a given component   1  Ask the component in xhtml   You can output the list directly in xhtml by binding that component to a request scoped variable and printing the eventNames property    lt p autoComplete binding    ac   gt  lt  p autoComplete gt   lt h outputText value    ac eventNames     gt    This outputs   blur  change  valueChange  click  dblclick  focus  keydown  keypress  keyup   mousedown  mousemove  mouseout  mouseover  mouseup  select  itemSelect   itemUnselect  query  moreText  clear    2  Ask the component in java code   Figure out the component implementation class and invoke its  implementation of javax faces component UIComponentBase getEventNames   method   import javax faces component UIComponentBase   public class SomeTest        public static void main String   args            dumpEvents new org primefaces component inputtext InputText             dumpEvents new org primefaces component autocomplete AutoComplete             dumpEvents new org primefaces component datatable DataTable                private static void dumpEvents UIComponentBase comp            System out println                  comp      n tdefaultEvent      comp getDefaultEventName        n tEvents      comp getEventNames                This outputs   org primefaces component inputtext InputText 239963d8      defaultEvent  valueChange      Events   blur  change  valueChange  click  dblclick  focus  keydown  keypress  keyup  mousedown  mousemove  mouseout  mouseover  mouseup  select  org primefaces component autocomplete AutoComplete 72d818d1      defaultEvent  valueChange      Events   blur  change  valueChange  click  dblclick  focus  keydown  keypress  keyup  mousedown  mousemove  mouseout  mouseover  mouseup  select  itemSelect  itemUnselect  query  moreText  clear  org primefaces component datatable DataTable 614ddd49      defaultEvent  null      Events   rowUnselect  colReorder  tap  rowEditInit  toggleSelect  cellEditInit  sort  rowToggle  cellEdit  rowSelectRadio  filter  cellEditCancel  rowSelect  contextMenu  taphold  rowReorder  colResize  rowUnselectCheckbox  rowDblselect  rowEdit  page  rowEditCancel  virtualScroll  rowSelectCheckbox    3   rtfm   -   Best option is to look into the documentation of the particular component in use as hopefully provided by the component developers  not limited to PrimeFaces btw   p ajax can be attached to any component providing ajax behaviors    The advantage over previous suggestions is that the documentation not only provides the event names  but also enhanced description of the event potentially enriched with an event type class that can be caught by a listener   For example the org primefaces event SelectEvent in case of    lt p ajax event  itemSelect  listener    anyBean onItemSelect    gt    and listener method signature public void onItemSelect SelectEvent  provides additional event contextual data   Where there is no explicit list of ajax events on a compoment in the PrimeFaces documentation  the list of on  javascript callbacks can be used as events by removing the  on  and using the remainder as an event name  The other answers in this question provides help on these plain  dom events too
