如何从（init）JSON函数调用（ko.observableArray）？

Question

Well the title is confusing so I'll give you my code to understand my problem

in knockout tutorials they use functions instead of JSON I mean like this:

data = [
  {
    id: 1,
    name: 'somehing'
  },{
    id: 2,
    name: 'somehing else'
  },
]

here is my problem

var ViewModel = function () {
    var self = this;
    self.dataList = ko.observableArray(data);
    console.log(ViewModel.dataList);
};

while on other websites and most of tutorials and projects in github uses JSON

var ViewModel = {
     dataList : ko.observableArray(data),
     init: function() {
      console.log(ViewModel.dataList);
      }
};

this line

     dataList : ko.observableArray(data),

when I try to call dataList it return this

function d(){if(0<arguments.length)return d.Wa(c,arguments[0])&&(d.X(),c=arguments[0],d.W()),this;a.k.Ob(d);return c}

and If I try to get its value console will tell me that dataList is not defined

but if I pass data directly to dataList like this (Which is not observableArray anymore) it will give me the full objects values in console

     dataList : dataList,

the return value in console

[Object, Object]

how can I call the ko.observableArray from init function?

I want to follow the tutorials on the web like this one but my issue is the same.

Actually it's not only ko.observableArray arrays also I cannot call ko.observable objects

Your code doesn't call ViewModel.dataList , it just accesses it, which gives you the function (remember observables are functions). To call it, add () :

console.log(ViewModel.dataList());
