Re: [Announcement] New feature for Tapestry 5.4.2 and 5.5: easily call event handler methods from JavaScript

[abangkis]

Hi. Thanks for the awesome improvement. I want to adopt it immediately. But
I've stumbled to one problem. How do I pass a parameter to the event?

Here's the onEvent method that will be invoked

@OnEvent("updateNodes")
void updateNodes(@RequestParameter(value = "param", allowBlank = false)
String param) {
    logger.debug("On update nodes {} ", param);
}

In the old way i could call it using

$('#saveChanges').click(function () {
    var my_param = {'example param'};

    routejs.jsClickCallback(tSpec.updateOrderEventLink, tSpec.zoneId,
JSON.stringify(my_param));
});

var jsClickCallback = function(listenerURI, zoneElementId, param) {
  var listenerURIWithValue = listenerURI;

  listenerURIWithValue = appendQueryStringParameter(listenerURIWithValue,
'param', param);

  zoneManager.deferredZoneUpdate(zoneElementId, listenerURIWithValue);
};

var appendQueryStringParameter = function(url, name, value) {
  if (url.indexOf('?') < 0) {
    url += '?'
  }
  else {
    url += '&';
  }
  value = escape(value);
  url += name + '=' + value;
  return url;
}
