jquery - Error while calling a Javascript function on HTML link click -


i have text box, html link & javascript function.

javascript function used client machine's ip-address. when click on link, trying call function & display result in textbox. however, fail obtain result.

this error getting.

uncaught typeerror: cannot read property 'ip' of undefined

my text box:

<input type="text" id="txtmyip" name="txtmyip"readonly>

my html link:

<a href="#" onclick="displayip();" >show ip address</a>

my javascript function:

var script = document.createelement("script");             script.type = "text/javascript";             script.src = "http://www.telize.com/jsonip?callback=displayip";             document.getelementsbytagname("head")[0].appendchild(script);              function displayip(response)             {                 document.getelementbyid("txtmyip").value = response.ip;             }

you need separate jsonp request function , display function. example:

function displayip() {     var script = document.createelement("script");     script.src = "http://www.telize.com/jsonip?callback=populateip";     document.head.appendchild(script);     }  function populateip(response) {     document.getelementbyid("txtmyip").value = response.ip; }

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
