Framework7 Keypad

Keypad plugin extends Framework7 with additional custom keyboards. By default it comes with predefined Numpad and Calculator keyboards, but it also can be used to create custom keyboards with custom buttons.

Where parameters - object - object with Keypad parameters. Required This method returns initialized Keypad instance

For example

var myKeypad = myApp.keypad({
    input: '#demo-numpad-limited',
    valueMaxLength: 2,
    dotButton: false
});

Keypad Methods & Properties

After we initialize Keypad we have its initialized instance in variable (like myKeypad variable in example above) with helpful methods and properties:

Properties
myKeypad.params	Object with passed initialization parameters
myKeypad.value	Current keypad value
myKeypad.opened	true if Keypad is currently opened
myKeypad.inline	true if Keypad is inline Keypad
myKeypad.container	Dom7 instance with Keypad HTML container
Methods
myKeypad.setValue(value)	Set new keypad value.
myKeypad.open()	Open Keypad
myKeypad.close()	Close Keypad
myKeypad.destroy()	Destroy Keypad instance and remove all events

Automatic initialization

Such predefined Numpad and Calculator keypads could be initialized automatically. Just use usual inputs but with special type attribute:

<input type="numpad">
<input type="calculator">

Access to Keypad's Instance

If you initialize Keypad as inline Keypad or using automatic initialization, it is still possible to access to Keypad's instance from its HTML container:

var myKeypad = $$('.keypad-inline')[0].f7Keypad;
