Retrieve the value of a form field

Installation

$ npm install @f/get-value

Usage

It gets the value of a form field and normalizes it a bit:

* Checkboxes/Radio-buttons return true if they are checked and don't have an explicit value set, and the value if they do. They return false if they are unchecked.
* Select will return the value of the option that is selected.
* ...Everything else just returns el.value.

``js
var controls = require('@f/form-controls')
var getValue = require('@f/get-value')
var brackets = require('@f/brackets')
var reduce = require('@f/reduce')

function serialize (form) {
return reduce(function (acc, ctrl) {
return brackets(acc, ctrl.name, getValue(ctrl))
}, {}, controls(form))
}
`
