问题 I'm trying to do this in coffeescript, http://jsfiddle.net/Q6348/8/ Specifically I'm trying to add handlers to my jQWordCloud to get the label for the word being clicked on In my coffeescript version while i < @counts.length x = @counts[i] @tag_list.push text: x.label weight: x.count handlers: click: -> temp = x -> alert "it worked for " + temp.label () ++i I get an unexpected TERMINATOR error presumably because of the (), but if you notice on the jsfiddle, removing that breaks the handler

问题 I just set up CoffeeScript (I'm also using Jade) for Meteor and it seems that my helpers (rendered and events functions too) do not work anymore. Template.signIn.helpers showForgotPassword: () -> return Session.get('showForgotPassword') The code seems to be properly generated but is embraced in an anonymous function. I'm getting the following error in the web console: Uncaught TypeError: Cannot call method 'helpers' of undefined (account.coffee:12) I'm wondering whether the code is run before

问题 I have such aync code async.eachLimit(teams, 1000, fetchTeamInfo, exit) I need to convert it to Promise (bluebird) I thought will be good to make something like: Promise.method (teams, 1000, fetchTeamInfo) -> async.parallelLimit arr.map((a, i) -> -> iterator a, i, arr ), limit But not sure is it right way 回答1: Well, I see you're using Promise.method so I'm assuming bluebird - bluebird comes with Promise.map with already supports what you're looking for with the concurrency parameter: const fn

问题 I'm making a package for Atom, and Travis CI keeps telling me my build failed. Update : I created a blank spec file and now my builds are passing. You can see my package here: https://travis-ci.org/frayment/language-jazz The console is telling me: sh: line 105: ./spec: No such file or directory Missing spec folder! Please consider adding a test suite in I went looking around at Atom packages on GitHub for 'spec' files and they seem to be CoffeeScript based, but I can't understand what on

问题 I am trying to determine if a document exists in a collection. If the document exists, I wish to add a property "unread = false" to an object. If it does not exist, I wish to insert the document and add "unread = true" to the object. Code in coffee script for the above is as follows: functionxyz = (db, uid, events, done) -> async.each events, (eventobj) -> if db.Event.find(eventobj).count() > 0 eventobj.unread = false else db.Event.insert eventobj eventobj.unread = true done null, events The

问题 How can I match on multiple occurrences of a token in a single message. module.exports = (robot) -> robot.hear /ITEM=(\d+)/, (msg) -> msg.send 'matched='+msg.match I would like to be able to match: blah blah blah ITEM=100 ITEM=200 ITEM=300 blah blah However I only get the first match with above code: match=blah blah blah ITEM=100 ITEM=200 ITEM=300 blah blah,ITEM=100 I can always just take the message and manually parse each line for each item, but it seems that using robot.hear should be able

问题 I'm following @coreyward's example for putting object edit forms in modal dialog windows in Rails, which is outlined in this answer and updated for rails 3.1 in this gist. I'm using Rails 3.2.8 and jQuery-Rails 2.1.3 (jQuery 1.8.2 is what's loading in the app). However, this coffeescript from the gist raises the error in the title, on line 7 (right after the comment). $ -> $modal = $('#modal') $modal_close = $modal.find('.close') $modal_container = $('#modal-container') # Handle modal links
