javascript - Knockout cloning does not work with function instances -


Actually what I read and whatever used to clone the array without any reference between me It was something like this:

var clonedArray = ko.observableArray (original array). Piece (0));

But in this it does not work: 

  var field = function (settings) {var _self = This; _self.Id = settings.Id; _self.flag = ko.observable (settings.Flag); Return _self; }; Var viewmodel = function () {var _vm = this; _vm.fields = ko.observableArray ([New field ({id: 1, flag: true}), new area ({id: 2, flag: wrong})]); _vm.fieldsCloned = ko.observableArray (_vm.fields (.) Piece (0)); Return _ VM; }; Ko.applyBindings (new viewmodel ());    
 
 
 answer  
 reference  
 < P> I had to face the same task; There is only one reason for cloning an observable array, how can I understand this, a JS object is viewable, then convert that object into an objective object. The KnockoutJS mapping plugin is required for the following functions:   
  function clone observer object (return ko.mapping.fromJS (ko.toJS (observableObject)); }

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
