event-value-extractor

Installation

npm install --save event-value-extractor

Usage

It can be used with all event listeners which sends an object with a target object that has a value attribute.

var React = require('react');
var eve = require('event-value-extractor');
 
React.createClass({
  render: function() {
    return <input onChange={eve.value(this.props.onChange)} />;
  }
});

.value(func, parser, parserArguments)

This will return a function that extracts arguments[0].target.name and arguments[0].target.value, which is used as arguments when func gets called. If parser is specified it will be called with the value as first argument and the arguments in parserArguments(must be one value or a list of values) as the next parameters.

.intValue(func)

This is a shortcut for value(func, parseInt, 10);

.floatValue(func)

This is a shortcut for value(func, parseFloat, 10);

.boolValue(func)

This is an extractor which will convert the following:

'true' or '1' or 1 => true
'false' or '0' or 0 => false
