PrimeFaces.ab function
11,378
The PrimeFaces.ab function is a shortcut function for PrimeFaces.ajax.AjaxRequest.
//ajax shortcut
ab: function(cfg, ext) {
return PrimeFaces.ajax.AjaxRequest(cfg, ext);
}
The PrimeFaces.ajax.AjaxRequest
can be asynchronous or synchronous.
The AjaxRequest uses the AjaxUtils, which handles all send, process, response, and update.
PrimeFaces.ajax.AjaxRequest = function(cfg, ext) {
cfg.ext = ext;
if(cfg.async) {
return PrimeFaces.ajax.AjaxUtils.send(cfg);
}
else {
return PrimeFaces.ajax.Queue.offer(cfg);
}
}
Passing a cfg (configuration) object to the PrimeFaces.ajax.AjaxUtils.send(cfg), this cfg object has:
- cfg.global: a boolean value used to trigger p:ajaxStatus if it's a true.
- cfg.onstart: to be called when the request is to be send.
- cfg.async: a boolean value, where if this call is asynchronous or not.
- cfg.source: can be a client id or an element defined by this keyword
- cfg.formId: if an explicit form is defined, or it would look into a parent source
- cfg.resetValues
- cfg.ignoreAutoUpdate
- cfg.fragmentId: used for the process of the components
- cfg.fragmentUpdate
- cfg.event: behaviour event, like click or change
- cfg.params: request params
- cfg.partialSubmit: if partial submit is enabled, there are components to process partially
- cfg.onerror: to be called when the request had an error status.
- cfg.onsuccess: to be called when the request had a success status.
- cfg.oncomplete: to be called when the request is completed.
Note: I came up with this explanation based on my understanding of the source code.
Also you can refer to this answer, might be helpful.

Cant seem to find documentation for PrimeFaces.ab function
PrimeFaces.ab({source:'signupForm:signupButton'}); return false;
Can anybody help me with what the code above is meant to do? It has been written against the
onclick
of a submit button.
