javascript - bacon.js Bus.plug: Uncaught Error: not an Observable : [object Object] -

-

i trying baconjs's tutorial. https://baconjs.github.io/tutorials.html#content/tutorials/2_ajax

but, got error @ "bus.plug"

var cart = shoppingcaret([]) var cartview = shoppingcartview(cart.contentsproperty) var newitemview = newitemview() cart.addbus.plug(newitemview.newitemstream)

error:

uncaught error: not observable : [object object] shopbundle.js:145 assertobservable shopbundle.js:2650 bus.plug

i use follows

  • baconjs@0.7.53
  • jquery@2.1.3
  • bacon-jquery-bindings@0.2.8
  • webpack 1.7.3

what doing wrong? thanks.

edit: 2015/3/25

cause newitemview.newitemstream not observable.
(newitemview.newitemstream instanceof bacon.observable returns false.)

and newitemview.newitemstream eventstream

eventstream {takeuntil: function, sampledby: function, combine: function, flatmaplatest: function, fold: function…}

isn't eventstream observable?

i have made newitemstream follows:

var $button = $('#addbutton'); var $namefield = $('#nametext'); var newitemproperty = bacon.$.textfieldvalue($namefield); var newitemclick = $button.aseventstream('click'); var newitemstream = newitemproperty.sampledby(newitemclick);

following work fine. miss when first time question.

/* and, try more simple code. has same error. */

 var somestream = bacon.interval(1000).map(function() {     return new date().gettime(); }); var bus = new bacon.bus(); bus.log(); bus.plug(somestream);

it caused "bacon-jquery-bindings"(https://www.npmjs.com/package/bacon-jquery-bindings)

var bacon = require('baconjs'); var $ = jquery  = require("jquery"); bacon.$ = require("bacon-jquery-bindings"); <-

it seems overwrite aseventstream function.

we should use "bacon.jquery"(https://www.npmjs.com/package/bacon.jquery)

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
