dom - javascript code doesnt work in browser -


i have code , using pspad editor when programing. when run "html page preview" in pspad works when try open in browser does't work. on chrome alerts "undefined not function". on firefox prints undefined , alerts empty window. on internet explorer nothing. can give me simple answer code example if possible?(this code should print content of xml)

<!doctype html> <html>     <head>     <script src="loadxmldoc.js"></script>     <script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>      </head>     <body>         <script>             var xmldoc= loadxmldoc('skoly.xml');              var d = document.createelement('div');              var t = document.createtextnode(xmldoc.xml);              d.appendchild(t);             document.write('<pre>' + d.innerhtml + '</pre>');              alert(xmldoc.xml);         </script>     </body> </html>

loadxmldoc.js:

function loadxmldoc(dname) {     try { //internet explorer         xmldoc=new activexobject("microsoft.xmldom");     } catch(e) {         try { //firefox, mozilla, opera, etc.             xmldoc=document.implementation.createdocument("","",null);         } catch(e) {             alert(e.message)         }     }     try {         xmldoc.async=false;         xmldoc.load(dname);         return(xmldoc);     } catch(e) {         alert(e.message)     }     return(null); }

this part returning error:

alert(xmldoc.xml);

i'm not sure trying achieve code trying return property "xml" of variable "xmldoc". in other words, work if xmldoc object looks this: 

var xmldoc = {     xml: "something here" };

it returning "cannot read property 'xml' of null" because xmldoc has value null , trying return property.

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
