javascript - knockout.js observable array binding -


this code

<div data-bind="foreach: baselist"> <div>     <span data-bind="text: basename"></span>     <div data-bind="foreach: subitems">        <span data-bind="text: subitemname"></span>          <a href="#" data-bind="click: $parent.removecard">del</a>     </div>      </div>  <button data-bind="click:addchild">add</button>

this viewmodel

    var simplelistmodel2 = function(baselist) {       this.baselist= ko.observablearray(baselist);      this.addchild = function(list) {        alert(list.basename());     }.bind(this);      self.removecard = function (cardlist) {                 this.cardlists.remove(cardlist);      }; };

this data passing viewmodel. how can include baselist in data? cant find baselist

var initialdata = [{     { basename: "danny", subitems: [         { subitemname: "mobile"},         { subitemname: "home"}]     },     { basename: "sensei", subitems: [         { subitemname: "mobile"},         { subitemname: "home"}]     }];

from html provided, can see structure this.

baselist -> {(basename), (subitems -> subitemname)}

so seems need pass data viewmodel during initialization. , remove parenthesis alert(list.basename); here because not observable object.

var simplelistmodel2 = function(baselist) {    this.baselist = ko.observablearray(baselist);    this.addchild = function(list) {      alert(list.basename);    }.bind(this);  };    var initialdata = [  { basename: "danny", subitems: [    { subitemname: "mobile"},    { subitemname: "home"}]  },  { basename: "sensei", subitems: [    { subitemname: "mobile"},    { subitemname: "home"}]  }];     ko.applybindings(new simplelistmodel2(initialdata));

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
