Javascript: Is it safe to refer to the <html> DOM-node? -


working in environment css-selectors available retrieving elements want obtain element in dom covers whole browser-window. using developer tools found out <body> has margin in case makes unsuitable requirements.

i further discovered <html> element covers whole area of browser-window. safe use dom-node when document properties? i.e. getting width/height example?

does chance <html> correspond referred document in javascript?

edit: side note on setup:

i'm working interns wrapped wd version , want coordinate mouse movements relative document. aiming using method selectbycssselector coodinate mouse movements respect selected element. working <html> node here seems work out far. never touched <html> node before , never saw else do, why wanted assured not bad using node.

the document object dom html object so, yes, correspond <html> tag, not in way think. not <body> or <span> tag. tells browser following code or information html. how <?php tells server there php code , <script type="text/javascript"> tells browser there javascript code. more information on that, check out this page.

if don't want width , height of body, can use window.innerwidth , window.innerheight. should height , width of entire window (excluding scrollbars or toolboxes).

you can use documentelement width , height of entire document.

var height = document.documentelement.clientheight; var width = document.documentelement.clientwidth;

this may final answer looking for, can find width , height of entire document using document in jquery.

var width = $(document).width(); var height = $(document).height();

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
