break works just like js: for cat in categories for job in jobs if condition do this break ## Iterate to the next cat in the first loop Your second case is not very clear, but I assume you want this: for cat in categories for job in jobs do this condition = job is … Read more
Introduction Webpack is mainly a JavaScript-bundler. Its “native” language is JavaScript and every other source requires a loader which transforms it to JavaScript. If you require() an html-file for example… var template = require(“./some-template.html”); …you’ll need the html-loader. It turns… <div> <img src=”https://stackoverflow.com/questions/26851120/./assets/img.png”> </div> …into… module.exports = “<div>\n <img src=\”” + require(“https://stackoverflow.com/questions/26851120/./assets/img.png”) + “\”>\n</div>”; If … Read more
CoffeeScript links both this and @ to the outer context, therefore you cannot access the context that jQuery provided (aka the desired “this”). Use event.target instead: class PostForm constructor: -> $(‘ul.tabs li’).on ‘click’, (event) => tab = $(event.target) @highlight_tab(tab)
I found the answer myself, it should be: class Dog extends Animal say: () -> super console.log “Hello from dog called #{ @name }”
Remove or comment out gem ‘coffee-rails’ from Gemfile. Change Javascript files that ends with .js.coffee to .js. Add config.generators.javascript_engine = :js to your application.rb. Make sure your tmp cache is cleared with rake tmp:cache:clear
You don’t need to add files to the original src, but rather to use coffee only “if”… So, use gulp-if gulp.task(‘task’, function() { gulp.src(‘./stuff/*’) .pipe(gulpif(/[.]coffee$/, coffee())) .pipe(gulp.dest(‘./dist/’)); }); See here more about gulp-if.
You are doing it the right way. This is described in the CoffeeScript documentation. I wouldn’t worry about the JS that it creates. Yes, it is a bit messy if you were to write it yourself, but this is one of the things that you have to live with when you use a re-writer like … Read more
form_values = new -> @[f.name] = f.value for f in $ ‘input, textarea, select’ this or form_values = new class then constructor: -> @[f.name] = f.value for f in $ ‘input, textarea, select’
For anyone that finds this question in the future, as of CoffeeScript 1.9.1 interpolated object literal keys are supported! The syntax looks like this: myObject = a: 1 “#{ 1 + 2 }”: 3 See https://github.com/jashkenas/coffeescript/commit/76c076db555c9ac7c325c3b285cd74644a9bf0d2
As of Mocha 1.0: coffee-script is no longer supported out of the box. CS and similar transpilers may be used by mapping the file extensions (for use with –watch) and the module name. For example –compilers coffee:coffee-script with CoffeeScript 1.6- or –compilers coffee:coffee-script/register with CoffeeScript 1.7+. (Quoting http://visionmedia.github.io/mocha/#compilers-option) So, you need to add the line … Read more
