Ajax Framework RemoteCommand

RemoteCommand provides a simple way to execute backing bean methods with javascript.

Sometimes you need to add a dynamic callback for when the remote command completes. Each remote command, when called, returns a promise-like object you can use for that purposes. Try opening a dev console and run the function "runRemoteCommand". See below for the code.

SERVER API TAG VDL

remoteCommand.xhtml
RemoteCommandView.java


<div class="card">
    <h:form>
        <p:remoteCommand name="rc" update="msgs" action="#{remoteCommandView.execute}"/>

        <p:remoteCommand name="rc2" update="msgs" action="#{remoteCommandView.execute}"
                         oncomplete="PF('msgsWidget').renderMessage({severity: 'info', summary: 'Data Received', detail: args.serverTime})"/>

        <h5>Basic</h5>
        <p>Execute a simple remote command by calling a javascript function.</p>
        <p:commandButton type="button" value="Send" icon="pi pi-refresh" onclick="rc()"/>

        <h5>Parameters</h5>
        <p>Passing parameters to the remote method as a javascript object.</p>
        <p:commandButton type="button" value="Send" icon="pi pi-refresh"
                onclick="rc([{name: 'param1', value: 'foo'}, {name: 'param2', value: 'bar'}])"/>

        <h5>Receive Values Back</h5>
        <p>Receiving values form the server as a serialized json object.</p>
        <p:commandButton type="button" value="Send" icon="pi pi-refresh" onclick="rc2()"/>

        <script>
            function runRemoteCommand(param1, param2) {
                var promise = rc([{name: 'param1', value: param1}, {name: 'param2', value: param2}]);
                promise.then(function (responseData) {
                    var serverTime = responseData.jqXHR.pfArgs.serverTime;
                    console.log("Request successful, returned server time is", serverTime);
                }).catch(function (error) {
                    console.error("Request failed", error);
                });
            }
        </script>
