# `append-field`
|
|
|
|
A [W3C HTML JSON forms spec](http://www.w3.org/TR/html-json-forms/) compliant
|
|
field appender (for lack of a better name). Useful for people implementing
|
|
`application/x-www-form-urlencoded` and `multipart/form-data` parsers.
|
|
|
|
It works best on objects created with `Object.create(null)`. Otherwise it might
|
|
conflict with variables from the prototype (e.g. `hasOwnProperty`).
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
npm install --save append-field
|
|
```
|
|
|
|
## Usage
|
|
|
|
```javascript
|
|
var appendField = require('append-field')
|
|
var obj = Object.create(null)
|
|
|
|
appendField(obj, 'pets[0][species]', 'Dahut')
|
|
appendField(obj, 'pets[0][name]', 'Hypatia')
|
|
appendField(obj, 'pets[1][species]', 'Felis Stultus')
|
|
appendField(obj, 'pets[1][name]', 'Billie')
|
|
|
|
console.log(obj)
|
|
```
|
|
|
|
```text
|
|
{ pets:
|
|
[ { species: 'Dahut', name: 'Hypatia' },
|
|
{ species: 'Felis Stultus', name: 'Billie' } ] }
|
|
```
|
|
|
|
