PrimeFaces' oncomplete attribute in JSF <h:commandButton>

Question

I didn't find an oncomplete attribute available in some tags in PrimeFaces within a standard JSF <h:commandButton>.

How can I get oncomplete-like functionality while using <h:commandButton>?

Answer 1

Since primefaces oncomplete is equivalent to plain JSF success event (for more details take a look at this answer comments , you should use the success event in the following way:

Inline solution

<h:commandButton id="someId" action="#{myBean.myAction}">
    <f:ajax onevent="function(data) { if (data.status === 'success') { alert('complete'); }"
        render="whatevet"></f:ajax>
</h:commandButton>

Another cleaner solution would be to use js function

<h:commandButton id="someId" action="#{myBean.myAction}">
    <f:ajax onevent="myJsFunction"
        render="whatevet"></f:ajax>
</h:commandButton>

In your js file add

function myJsFunction(data) {
    if (data.status === 'success') {
         alert('complete');
    }
}

In case you are looking for a way to detect the completion of non ajax submit you can adopt the following idea from here Detecting the File Download Dialog In the Browser

The easiest solution would be to use

$(document).ready(function () {
// check if some condition is meet and do something...
});
