javascript - Can't fire function on document load -


html:

<input class="test removeme" type="text">

jquery:

$(function () {     function isempty() {         if (!$(".test").val()) {             $(this).removeclass("removeme");         } else {             $(this).addclass("addme");         }     }     isempty(); });

please, tell me, wrong?

i want isempty fire on load/reload , check if input has value. if doesn't, remove removeme class. if have value, add addme class it.

console empty, can't figure out why isn't working properly.

update:

very odd... fire proper alert relatively if empty or not, doesn't add/remove classes. https://jsfiddle.net/37tt3x72/1/

update 02

it work, not exactly... https://jsfiddle.net/37tt3x72/2/ this isn't working... if replace targeted element, work. question remained: why this isn't working here?

call function document on ready function.

function isempty() {     if (!$(".test").val()) {         $(this).removeclass("removeme");     } else {         $(this).addclass("addme");     } }  $(document).ready(function(){   isempty(); });

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
