select-box

A minimal DOM <select> utility. Pull requests / suggestions welcome.

//create a select box
var box = require('select-box')(['Monday', 'Tuesday', 'Wednesday'])

//select an item programmatically
box.select('Tuesday')

box.on('change', function(ev) {
	//get name of selected item
	console.log(box.selected())
})

//have it displayed on page
document.body.appendChild(box.element)

Usage

See demo for a complete example.

box = SelectBox([items])

Creates a new select box with the optional items to add.

items can be a string, or an array of strings.

Or, it can be a key-value pair like so:

var box = SelectBox({
    hello: 'Hello!',
    goodbye: 'Goodbye!'
});

Now logging console.log(box.element.outerHTML) results in:

<select>
    <option value="hello">Hello!</option>
    <option value="goodbye">Goodbye!</option>
</select>

box.element

The DOM element for this <select> box.

box.add(items)

Adds a single item or an array of items to this select box. An "item" is just a string (which indicates value and name), or an object:

{
	name: 'Tuesday',
	value: 'tuesday', 
	disabled: false
}

Returns this for chaining.

box.clear()

Clears the data in the box. Returns this for chaining.

box.set(data)

Clears the current data in the box and adds the specified data. Returns this for chaining.

box.selected()

Gets the selected value for this combo box.

box.selectedIndex()

Same as selected(), but returns the index of the entry in the data list.

box.select(value)

Selects the item by value in this combo box, if it exists.

Returns this for chaining.

box.data

The internal data which was passed to add, set or a constructor. This should not be modified externally, although it could be used to retrieve values and names of each entry.

box.on('change')

Receives the onchange DOM event.
