kandi X-RAY | backbone.radio Summary
Backbone.Radio provides additional messaging patterns for Backbone applications. Backbone includes an event system, Backbone.Events, which is an implementation of the publish-subscribe pattern. Pub-sub is by far the most common event pattern in client-side applications, and for good reason: it is incredibly useful. It should also be familiar to web developers in particular, because the DOM relies heavily on pub-sub. Consider, for instance, registering a handler on an element's click event. This isn't so much different than listening to a Model's change event, as both of these situations are using pub-sub. Backbone.Radio adds two additional messaging-related features. The first is Requests, an implementation of the request-reply pattern. Request-reply should also be familiar to web developers, as it's the messaging pattern that backs HTTP communications. The other feature are Channels: explicit namespaces to your communications.

QUESTION
Summary Using jquery.blockUI seems to hide / swallow / mask button click event.

(all latest version)
The App
The app consists of a text input and a button.
In terms of backbone/marionette terminology, there is
- a top view which has 2 regions
- container view which as the text input
- footer view which has the button
- The container view is backed by a model.
- The footer has a button, Clicking the button sends a backbone.radio event.
- This event is picked up in the top view.
When the user leaves the text input, an API (server / backend) is called. In the example a Promise / setTimeout is used to simulate the call.
In the example the button calls console.log.

Here is the JSFiddle Example on JSFiddle and below the Javascript code

Your expectations are wrong. There is no implicit mechanism in JavaScript that serializes asynchronous events one after the other has completed. You (developer) are responsible for synchronization of asynchronous events.
Why is the click event swallowed?
Click event fires when a mousedown and mouseup event occur on the same element. And this is not your case. The order of events is as follows:
mousedownonchangeon; causes displaying overlayviablockUImouseupon overlayclickon closest common parent element of elements that triggeredmousedownandmouseup, which is
Technically it seems to be impossible to click the button after the input changed, because overlay is displayed before mouseup, however there is one way. If you click and hold the mouse button while the overlay is being displayed and release afterwards, the click event will be triggered on the button, but this isn't something that you want anyway.
Try to play with this snippet. It logs every mousedown, mouseup, click and change event. It registers asynchronous change event handler on thet does nothing for the first second, then displays an overlay, then sleeps for 3 seconds and finally hides the overlay. You can observe various behaviours based on how long you kept the button mouse depressed.
Change input text and quickly click the button
button.mousedown
input.change
button.mouseup
button.click
Change input text, click the button and hold for 1 sec, then release
button.mousedown
input.change
div.mouseup
body.click
Change input text, click the button and hold for 4 sec (until overlay disappears), then release
button.mousedown
input.change
button.mouseup
button.click
QUESTION
I am currently working with the "NinjaForms" plugin for WordPress, which provides custom form management for the backend. It's based on Marionette / Backbone JS. After some research, I had no problem triggering JavaScript functions on input change and on form submit. However, I have not found a way to fish for an event once the form is initialised / rendered / shown (any of these, really).
What I am doing right now is initialising a Marionette object, adding listeners to a radio and then adding functions to execute it on event:

QUESTION
I'm converting a largish project to webpack and am encountering a build error (and in fact different errors depending on how I attempt to resolve). I'm not super skilled with webpack yet and would love some help with what the typical solution is to such problems.
There seems to be a conflict between some dependencies:
...ANSWER
Answered 2018-Apr-25 at 18:44Compiling things in node_modules wasn't really a thing during Babel 6's original lifetime, so it can be painful. Up until recently, we explicitly recommended that users set exclude: /node_modules/ in their babel-loader config because it was, and still is, a little dangerous to run Babel on arbitrary third-party code.
For your specific issue, you have two options:
- Use
exclude: /node_modules/so that Babel only processes your own code. - Upgrade to
beta.46, because we've now added first-class support for the concept of Node's packages, which we didn't have before. Babel >= beta.45 will only search for.babelrcfiles in the "root" package.
I'll also add that if your Babel config is in a .babelrc right now, that will not affect things in node_modules, so if your intention is to compile third-party code, you'll want to move your config to a babel.config.js file in your project root, or put it in your webpack.config.js directly. You may also probably want to explicitly pass sourceType: 'unambiguous' as a Babel option.
Finally, if you're using the beta, we are absolutely still making breaking changes, so you should not use ^ in your package.json, since that will make you take the most recent version of everything, which we might have broken compared to earlier releases.
QUESTION
Long time lurker here. I am putting together a website on WordPress that allows clients to log in to schedule pickup and delivery of their laundry. Currently I am using Ninja Forms to take my orders for a variety of reasons. The issue I am running into is modifying the datepickers. I have used and modified some WP plugin code to disable past dates, but I can't quite figure out how to do what I want it to do.
I want to disable days in the past and the current day as well. Here is the code I have now:

QUESTION
I've looked and seen the messages about putting underscore before backbone and marionette. I've done that. When I run my sample I still get:
Uncaught TypeError: Cannot read property 'extend' of undefined at MessageDetailsView.js:1
I'm not trying to instantiate the view, so it doesn't seem that I would need a model yet.
I'm trying to convert my html/jquery to marionette and this is my start. Once I get the ItemView to load, then I will see if I can put it in a CollectionView or just add directly to a div.
Any thoughts?
