javascript - Using $sce in Angular -


i'm having trouble getting head around showing iframes in angular app. users allowed enter youtube url , app convert straight video.

of course, angular won't allow directly have explicitly "trust" contents use show iframe:

$sce.trustasresourceurl(url_of_video)

however, how back? want able send url back-end in sanitized form it's no longer original url string.

update:

experimenting , came code:

angular.foreach($scope.task.items, function(item) {   item.data = $sce.gettrustedresourceurl(item.data); //this gets rejected $sce   item.data2 = $sce.gettrustedresourceurl(item.data); //this accepted , i'm free post url });

i've noticed can create new name/value pair in array , assign original url if try assign item.data trusted form of sanitized data rejects it! hmmmmm! why this?

any ideas?

update 2 decided create 2 versions of data, 1 front end (which "trusted" $sce) , 1 back. appears have solved issue moment.

take @ this answers (which contains links yet more answers , resources).

you should understand implications of trusting content entered user , $sce there for.

if want allow youtube urls, might better idea "white-list" urls (instead of trusting url entered user).
(don't forget sce not there make app bullet-proof, tool make safer , audit easier/more reliably.)

that said, here how configure angular's sce allow urls www.youtube.com:

.config(function ($scedelegateprovider) {     $scedelegateprovider.resourceurlwhitelist([         'self',                    // trust resources same origin         '*://www.youtube.com/**'   // trust resources `www.youtube.com`     ]); });

see, also, short demo other answer (that want).

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
