backbone.js - Iterating through multi-nested objects in Javascript with Underscore -

-

I am using backcon and underscore. My object looks like this: 

  TopObject: {name: ", middleObjects: []} Middle Object: {name:" ", Object below: []} Object below: {name : '', Some other terms: ''}   
 So if you have a top object, then it will have several middle objects in the form of a property, and one near the middle object There will be a property as the only place  
 I am not sure how I can display these areas in a table. It has been using underscores so far.    var has some data in someTopObject = new TopObject (); // (some toobogs.get ('medium objects'), function (midobase) ) {// do something with midobage.name // do not make sure how to get the middle object.} Botam object});   
 Right now I know that in the below object There can be only 2 items, so I think I have the following objects in the first and second ob Getting Jack could hardly be coded, but I was not sure if there was any more great way. Thanks!   
 
 
 nestes loop?  
  _. Each (some TopObject .get ('medium objects'), function (midob) {_.each (midObj.get ('floor objects'), function (objas below) {// do stuff});});

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
