For that, the <p:remoteCommand> component is intented. Basically, it allows you to let PrimeFaces generate a JS function reference with the desired function name which in turn invokes the desired backing bean action method.

E.g.:

<h:form>
    <p:remoteCommand name="functionName" action="#{bean.submit}" />
</h:form>

Which is then to be invoked as:

<script>
    functionName();
</script>

You can use a JS object as argument in order to pass request parameters:

<script>
    functionName({ paramName: "paramValue" });
</script>

Which is then available in action method as:

String paramName = externalContext.getRequestParameterMap().get("paramName"); // Contains "paramValue".
