jquery - How to make rotate to 45 deg and animate change left same time? -


how make in duration rotate angle 45 deg , stop? can't find way make angle in below demo increase 45 during animate change margin-left, how it??

http://jsfiddle.net/8tp9d/37/

var angle = 0;  $('.btn').click(function(){ $("#a").animate ({     "margin-left": "+=200px"      },     {     step: function (now, fx) {         angle += 1;         $(this).css({             "-moz-transform":"rotate("+angle+"deg)",             "-webkit-transform":"rotate("+angle+"deg)",             "-ms-transform":"rotate("+angle+"deg)",             "-o-transform":"rotate("+angle+"deg)"         });     },     duration: 300 }, "linear"); });

there no reason increment rotation each step can use .animate , give target value , automatically step value (and fluently)

if doing this, use .css , css transitions performs better jquery's transform. following

$('.btn').click(function(){    $("#a").css ({      "-moz-transform":"translatex(200px) rotate(45deg)",      "-webkit-transform":"translatex(200px) rotate(45deg)",      "-ms-transform":"translatex(200px) rotate(45deg)",      "transform":"translatex(200px) rotate(45deg)"    });  });
#a {    margin-top:25px;    margin-left:25px;    width: 150px;    height: 150px;    list-style: none;    background-color: blue;    -webkit-transition:.3s linear;    -moz-transition:.3s linear;    -ms-transition:.3s linear;    transition:.3s linear;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>  <div class="btn">btn</div>  <ul>    <li id="a">      <span>content</span>    </li>  </ul>

for performance recommend using vanilla javascript well

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
