backbone.js - Marionette Layout: trigger event on child view -


i have layout view, itemview inside it. have event in item view triggers save function. inside save function trigger event layout captures.

so in code below, in onclicksave modelsavesuccess i'd trigger function in parent layout, have tried this.methodinparent() doesnt work

childview

define(["marionette", "underscore", "text!app/templates/client/form.html", "app/models/client"], function(marionette, _, template, model) {   "use strict"   return backbone.marionette.itemview.extend({     events: {       "submit #saveclient": "onclicksave"     },     onclicksave: function(ev) {       ev.preventdefault()       return this.model.save({}, {         success: function() {           console.log('success - trigger ')         },         error: function(request, error) {           console.log(error.responsetext)         }       })     }   }) })

a way without introducing heavy coupling use marionette's event aggregator in linked exemple if use backbone.marionette.application.

// in view ... success: function() {     app.vent.trigger('myview:modelsaved'); } ...  // in layout initialize() ... app.vent.on('myview:modelsaved', function(){    console.log('model saved in itemview'); }); ...

if don't use backbone.marionette.application can create own backbone.wreqr.eventaggregator.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
