javascript - Backbone each undefined -

-

why item variable undefined in backbone example?

var action = backbone.model.extend({ defaults: {     "selected": false,     "name": "first action",     "targetdate": "10-04-2014" } });  var actions = backbone.collection.extend({     model: action });  var actioncollection = new actions( [new action(), new action(), new action(), new action()]);  _.each(actioncollection, function(item) {     alert(item); });

jsfiddle here: http://jsfiddle.net/netroworx/klyl9/

change to:

actioncollection.each(function(item) {         alert(item); });

and works fine.

this because actioncollection not array, _.each(collection) not work collection.each because function build backbone collection.

that being said, works:

_.each(actioncollection.tojson(), function(item) {         alert(item); });

because collection actual array.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
