javascript - HTML how to target a link in a iframe to another iframe -


working code

assuming have page 2 different iframe first menu , second container of selected page.

how can @ click of link in menu frame display selected page iframe container?

in menu page have 

...  </li>          <li class="title"><a href='javascript:parent.document.getelementbyid("frame").src = "pages/setting.php"'><?php echo $lang['menu_impostazioni']; ?></a>          <img src="images/bullet_arrow_down.png" /></li>         <li class="sub-menu">           <ul> ...

in index this:

... <iframe id="menufrm" src="menu.php" width="250px" height="700px" frameborder="none"></iframe> <iframe name="frame" src="" width="99%" height="99%" frameborder="none"></iframe>  ...

but this, when click in button in menu page displayed correctly in container, menu.php disappears , in place appears string relative path of document displayed in iframe.

how fix it?

<iframe src="frame1.html" name="myframe"> <a href="frame2.html" target="myframe">

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
