mithril-util-attributes

Utility for Mithril creating attributes

Usage

Basic Usage

First create the builder, use it and get the attributes to use them in the mithril function.

var m = require('mithril')
var ma = require('mithril-util-attributes')
var div = m( "div", ma().id( "0" ).get() )

Create CSS Classes

var div = m( "div", ma().css( "highlight", ctrl.isHighlighted(), "bold", ctrl.isBold(), "italic",  ctrl.isItalic() ).get() )
// when ctrl.isHighlighted() == true
// when ctrl.isBold() == false
// when ctrl.isItalic() == true
// will create { 'class': 'highlight italic' }

Create Event bi-directional binding

m( "input", ma().name( "description" ).value( "initialValue" ).oninput( ctrl.setDescription ).get() )

Builder builder.withAttr( String attrName, String event, Object initialValue, Function callback [, Object thisArg ] )
