Is there a way to tap into the default JSF ajax(JS) event queuing system in order to execute events sequentially?
I am attempting to align my JS events with this queue. Is there a global variable that can facilitate this synchronization?

If you're looking to add event listeners on JSF ajax requests, you can utilize <f:ajax onevent>
along with jsf.ajax.addOnEvent
. By doing so, you can run JavaScript code before sending the ajax request, after receiving the response, and/or once the HTML DOM is updated. This approach could potentially meet your specific requirements.
Here's an example of how the event listener function can be structured:
function someAjaxEventListener(data) {
var status = data.status;
switch(status) {
case "begin":
// Executed just before the ajax request is sent.
break;
case "complete":
// Triggered immediately after receiving the ajax response.
break;
case "success":
// Activated right after the HTML DOM is updated.
break;
}
}
You can then associate this function with a specific <f:ajax>
tag like so:
<f:ajax ... onevent="someAjaxEventListener" />
To apply the event listener globally across all <f:ajax>
components in the view, you can use the following method:
<h:outputScript>jsf.ajax.addOnEvent(someAjaxEventListener);</h:outputScript>
(For better organization, consider placing this code in a separate JS file loaded using <h:outputScript name>
)
