Rails has a built in mechanism for handling nested forms. Lets say you have: class Company < ActiveRecord::Base has_many :brands accepts_nested_attributes_for :brands end class Brand < ActiveRecord::Base belongs_to :company end class CompaniesController < ApplicationController def new @company = Company.new @company.brands.new # seeds the form with a new record for brands end def edit @company = … Read more

The problem with your code is that you are trying to work on a piece of code that has already started to operate. In simpler words, the setInterval method will be called every 1000ms, no matter what the value of stopped variable is. If you wish to really stop the log, you can do any … Read more
If in a namespace eval, use variable to avoid the weirdness of the variable name resolver. (I don’t want to describe in detail what it does, other than to say that code that relies on it can be automatically described as buggy and in hard to accurately describe ways.) If in a procedure, (usually) use … Read more

If you have average skill using an SDK should be helpful for you. Start out with something like XNA Game Studio to see how those concepts are done. This document is the starting point for the SDK https://msdn.microsoft.com/en-us/library/bb200104.aspx and the “Network” concepts you are specially looking for are discussed here: https://msdn.microsoft.com/en-us/library/bb975947.aspx As for the database … Read more
If you have CSS styles isolated in a javascript string, you can get the width value with this regex: var re = /\.body\s*\{[^\}]*?width\s*:\s*(.*);/m; var matches = str.match(re); if (matches) { var width = matches[1]; } Test case here: http://jsfiddle.net/jfriend00/jSDeJ/. The height value can be obtained with this regex: \.body\s*\{[^\}]*?height\s*:\s*(.*);/m; If you just want the text … Read more
This seems to work for me, and is very close to what is given in the question. You have to return after iterating over all items (not just the first in the for-loop). Also, see that if I have an item 1 two places in the list i will add it twice to the dictionary … Read more
Ok, let’s see if this answer suits your request.

Remove the $() stuff around your result string. Also, you should check to make sure g.time.time isn’t zero before division. var speed = (g.time.time === 0 ? 0 : Math.floor( (Math.ceil(g.score.score / 5) / g.time.time) * 60)) var result=”<ul><li>You type “+g.score.score+’ characters in ‘+g.time.time+’ seconds.</li><li><u>Your speed</u> : about ‘ + speed +’ words per minutes!</li></ul>; … Read more
