/*
 * Build 5 buttons in a toggle group

for (i = 0; i < 5; i++) {
  butt = PushButt({ title: 'button-' + i })
  butt.appendTo(button)
  butt.addToggleGroup('groupA')
  butt.on(butt.event, callback)
  buttonGroup[i] = butt
}
/*
 * Remove 5th button from group
 */
buttonGroup[4].removeToggleGroup('groupA')

button.appendChild(document.createElement('br'))
button.appendChild(document.createElement('br'))
/*
 * Build another 5 toggle group
 */
for (i = 5; i < 10; i++) {
  butt = PushButt({ title: 'button-' + i })
  butt.appendTo(button)
  butt.addToggleGroup('groupB')
  butt.on(butt.event, callback )

  buttonGroup[i] = butt
}
/*
 * Remove 10th button
 */
buttonGroup[9].removeToggleGroup('groupB')


function callback (id) {
  result.innerHTML = "Caught " + id
}

Methods

var butt = PushButt(opts)

Returns a push button instance using options opts. Available options are:

{
  "active": true || false
, "title": "Button Text Here"
}

butt.appendTo(target)

Append the button widget to the dom element or query selector string target.

butt.set(arg)

If arg is a "bool" this method programmatically toggles the value of the button, true sets button into on state, false sets button into off state. If arg is a "string" the set method sets the displayed title of the button.

butt.addToggleGroup(groupname)

Adds the button butt to the group groupname. This turns the buttons into a radiobutton like mode where a single button is active at any time. Setting a new button as active deactives the previously active button.

butt.removeToggleGroup(groupname)

Removes the button butt from the group groupname.

Events

butt.on(butt.event, function (id) {})

Every time a button becomes active it emits event 'butt.event' which is a unique ID for that button. The event value is the numberic id of the button.

Attributes

butt.element

html dom element container

butt.id

The numeric ID of the button

butt.event

The emitted event name on button press. Event name is 'pushbutt-' + butt.id.

butt.title

The title of the button. Note that setting this property will not cause the title text in the button element to change. The butt.set('newName') method will set both butt.title as well as set the text in the html element.

install

With npm do:

npm install pushbutt

Use browserify to require('pushbutt').
