Knockout Template Binding Performance (v5)

Revision 5 of this benchmark created by jdiaz5513 on

Description

The goal is to test Knockout performance (using Native Templating) between:

  • not using a template binding
  • using a template binding with a <script> tag
  • using a template binding with a <template> tag

See: http://knockoutjs.com/documentation/template-binding.html

Setup

var ViewModel = function() {
    
        var self = this;
    
        //---Properties---
        self.birthDate = ko.observable( "July 1" );
        self.anniversaryDate = ko.observable( "July 2" );
        self.paroleDate = ko.observable( "July 3" );
    
    
        //---Behavior---
        self.changeData = function() {
    
                var now = new Date();
    
                self.birthDate( now.getTime() );
                self.anniversaryDate( now.getTime() );
                self.paroleDate( now.getTime() );
        }
    
    };
    
    
    
    
    //---ACTIVATE KO---
    var viewModel1 = new ViewModel(); 
    ko.applyBindings( viewModel1, document.getElementById(  "noTemplateBinding" ) );
    
    //---ACTIVATE KO---
    var viewModel2 = new ViewModel(); 
    ko.applyBindings( viewModel2, document.getElementById( "scriptTagBinding" ) );
    
    //---ACTIVATE KO---
    var viewModel3 = new ViewModel(); 
    ko.applyBindings( viewModel3, document.getElementById( "templateTagBinding" ) );
