marionette-throttle

Throttle methods! This is commonly used to disable multiple clicks on a button. Each method which you want to throttle should return a promise. Every time a method is invoked, an event is dispatched.

$ npm install marionette-throttle --save

Usage

Define a view as follows:

var Marionette = require('marionette'),
    throttleBehavior = require('marionette-throttle');

return Marionette.ItemView.extend({
    behaviors: {
        throttle: {
            behaviorClass: throttleBehavior
            methods: ['save']
        }
    },
    events: {
        // Method name inside event string.
        throttle:save:enabled: 'enableSomeCssStuff',
        throttle:save:disabled: 'disableSomeCssStuff',

        // Method name as an argument.
        throttle:enabled: function (methodeName) {},
        throttle:disabled: function (methodeName) {}
    },
    // This function will be wrapped because its name is present in
    // the behavor `methods` config.
    save: function (e) {
        e.preventDefault();

        return this.view.model.save();
    }
})

Normally you will only have 1 button which triggers an action:

    events: {
        'click @ui.saveButton': 'save'
    },
    save: function (e) {
        // Some save action.
    }

If you also want to programmatically call the save action (e.g. this.save()), then it is recommended to split the save into two functions. This way you can throttle saveByEvent and use the save function programmatically without being throttled.

    events: {
        'click @ui.saveButton': 'saveByEvent'
    },
    saveByEvent: function () {
        this.save();
    },
    save: function () {
        // Some save action.
    }
