javascript - How to enable dates that match with the data in rangeselector? -


i have added datepicker highchart follows. 

$(function() {  $.getjson('http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?', function(data) {     // create chart     $('#container').highcharts('stockchart', {           rangeselector : {             selected : 1         },          title : {             text : 'aapl stock price'         },          series : [{             name : 'aapl',             data : data,             tooltip: {                 valuedecimals: 2             }         }]      }, function(chart){          // apply date pickers         settimeout(function () {             $('input.highcharts-range-selector', $(chart.container).parent())                 .datepicker();         }, 0);     }); });   // set datepicker's date format $.datepicker.setdefaults({     dateformat: 'yy-mm-dd',     onselect: function(datetext) {         this.onchange();         this.onblur();     } });

});

how can prevent users select dates out of data range? example, if oldest data have 25-12-2010, in date selector dates before 25-12-2010 should disabled. appreciate help

you can set beforeshowday callback. should return true or false if date valid - in case can check if date within navigator range.

  $.datepicker.setdefaults({     dateformat: 'yy-mm-dd',     beforeshowday: function (date) {       var d = new date(date).gettime();       var {min, max} = chart.navigator.xaxis;        return [min <= d && d <= max];     },

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
