asp.net mvc - Adding another "Pet" to a Model Form -


simplified example.

i have model has few fields:

ownerfirstname ownerlastname list<pet> pets (pet few string fields)

the ui needs allow user add number of new pets. ui pet entry mvc template _peteditor.cshtml

client side, how add new pet model's pet collection, add new set of fields pet _peteditor.cshtml ?

when user submits form, mvc model pets added.

you use javascript dynamically create indexed inputs post back. example create dummy set of inputs cloned , displayed when click 'add pet' button (assumes pet properties displayed in table id='pets')

<div id="newpet" style="display:none">   <tr>     <td><input type="text" name="pets[#].type value /></td>     <td><input type="text" name="pets[#].breed value /></td>     <td>.....</td> // more properties of pet     <td><input type="hidden" name="pets[#].index" value ="%"/></td>   </tr> </div>

note use of dummy indexer prevent 1 being posted back

and script

$('#addbutton').click(function() {   var index = (new date()).gettime();    var clone = $('#newpet').clone();   // update index of clone   clone.html($(clone).html().replace(/\[#\]/g, '[' + index + ']'));   clone.html($(clone).html().replace(/"%"/g, '"' + index  + '"'));   $('#pets tbody').append(clone.html()); }

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
