javascript - Inaccessible global variable -


this driving me crazy.

jquery notifies me message [prevobject: r.fn.init(1)] when try retrieve variable $venusthumbdiv inside collector() function. in other words, guess jquery doesn't find $('.venus-thumb-div') inside page (althought there 4 divs class).

what's incredible in snippet below code works should identical piece of code doesn't work if write in editor , run on same browser!! way let work "offline" decommenting var declaration inside collector() function, it's totally useless 'cause need var $venusthumbdiv global.

has clue on why i'm having problem?

var venusgallery = function () {        var $venusthumbdiv              = $('.venus-thumb-div');        /* @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ */      /* @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@       public fns       @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ */      /* @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ */      /* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ */      /* ~~~~~~~~~~~~~~~~~~~     collector()    ~~~~~~~~~~~~~~~~~~~ */      /* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ */      var collector = function () {          // var $venusthumbdiv              = $('.venus-thumb-div');          console.log("div number: " + $venusthumbdiv.length);          console.log($venusthumbdiv);       };        /* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ */      /* ~~~~~~~~~~~~~~~~~~~     setopts()    ~~~~~~~~~~~~~~~~~~~ */      /* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ */      var setopts = function (choosen_options) {          var options = {              progression:    '<div id="venus-progression" style="color: white"></div>',              share:          '<div id="venus-share"></div>',              fullscreen:     '<div id="venus-fullscreen"></div>',              download:       '<div id="venus-download"></div>',              description:    '<p id="venus-description"></p>'          };            /* default: no options; options showed if declared , set true in venusgallery.setopts({}); */          $.each(options, function (key, value) {              if (choosen_options[key]) {                  options[key] = value;              } else {                                    // if false or not declared: not showed                  options[key] = '';              }          });            venusopts = options;      };      /* *****************************************************************************************************************       * ************************************************************************************************************** */      /* @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ */      /* @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@       public fns definition       @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ */      /* @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ */      return {          setopts: setopts,          collector: collector      };      /* *****************************************************************************************************************       * ************************************************************************************************************** */    }();

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
