unbind

function

Unbind event handlers from a Map.

`map.unbind(eventType[, handler])`

Parameters

eventType {String}:
the type of event to unbind, exactly as passed to bind

handler {function}:

the handler to unbind

var map = new Map({ a: 1 });

function log(){
    console.log("val", map.attr("a");
}

map.bind("change", log);

map.attr("a", 2);

// Bind callback called.
map.unbind("change", log);

unbind unbinds event handlers previously bound with bind. If no handler is passed, all handlers for the given event type will be unbound.

var i = 0,
    increaseBy2 = function() { i += 2; },
    increaseBy3 = function() { i += 3; },
    o = new Map();

o.bind('change', increaseBy2);
o.bind('change', increaseBy3);
o.attr('a', 'Alice');
i; // 5

o.unbind('change', increaseBy2);
o.attr('b', 'Bob');
i; // 8

o.unbind('change');
o.attr('e', 'Eve');
i; // 8
