What is the best way to force a single click on a binding (disabling method call for 1 second after click) in Aurelia.
In knockout I would have created a new custom singleClick binding but in Aurelia i'm not sure I can do this.
Should I look at building my own binding behaviour something like click.delegate="onClick() & prevent-double"
Can I use an existing binding behaviour something like throttle or debounce click.delegate="onClick() & throttle"
Is a custom element the answer, creating a new single-click button that takes an onclick method and disables the button for a second when clicked?

I am trying to create component which would extend v-btn in such a way that every time I click a button, it should emit short beep, and disable the button for 5 seconds.
It would be ideal for the button to change color while disabled.
This is a problem, since color is a property, and I can't overwrite it's value...
Also, when I try to invoke super.click(e), I get an error.
You can check example here: https://codesandbox.io/s/elegant-glade-pnhqx
Your Btn component should just "use" v-btn rather than extending it.
v-bind="$attrs" is to copy any <btn>'s attribute onto <v-btn>.
#click event is captured and reemited as-is after doing what needs to be done
See https://codesandbox.io/s/immutable-paper-w1wck?file=/src/components/Btn.vue:41-56
i used this.outletService.add('BottomHeaderSlot', factory, OutletPosition.BEFORE); during the search button click handler to add a custom component in the BottomHeaderSlot. I intended to add searchOverlay under the header to add customized search behavior.
But my custom component is not shown under the header after calling outletService.add. I refered to this https://sap.github.io/cloud-commerce-spartacus-storefront-docs/outlets/ . Does outletService support dynamic adding component during runtime?
Following is my button handler
open(): void {
const factory = this.componentFactoryResolver.resolveComponentFactory<SearchOverlayComponent>(SearchOverlayComponent);
this.outletService.add('BottomHeaderSlot', <any>factory, OutletPosition.BEFORE);
this.cd.markForCheck();
That's a good question. At the moment it is a not a feature supported from our outlets.
A solution you could do is inject the component in a more static manner (either CMS or outlet when the app initializes like seen here https://github.com/SAP/cloud-commerce-spartacus-storefront/blob/develop/projects/storefrontlib/src/cms-components/asm/services/asm-enabler.service.ts)?
Your component could then be wrapped with an <ng-container *ngIf="open$ | async></ng-container> where open$ is an observable for the state of the search box. That way the component only appears in the dom when the searchbox is open.
The idea of dynamically adding a components through outlets is a good one we will keep in mind. I will open an issue on Github as an improvement.
Looking to find where we can insert our own data for triggered events.
I have an extension that use to call onImpl(events, selector, data, callback), but that was back in 2.3.7. What is the updated way to add my event data if I want to pass data that can be used with the event?
As far as I know, it is not possible to pass data to core events anymore. But you can do it when you emit the events programmatically.
I'm assuming this is the extension that you mentioned. If you just want the paz/zoom functionality, you can use the pan-zoom extension.
I'm not sure if a toolbar extension would be any useful. The customization of the toolbar with an extension would be very limited. You can create a fancy toolbar, style and position it as you like and connect the buttons with Cytoscape events with jQuery or other similar libraries.
P.S: instead of passing the data to the event, you may keep the data in a global variable and access it from callback function.
Is there a way to communicate from the parent viewmodel to a KnockoutJS component?
I have a component that contains a bootstrap modal dialog box, to search for customers and return a selected customer. At present, to make the dialog box appear, I pass an observable boolean from the viewmodel in the component's params attribute. To make the dialog appear I set this to true, which invokes the dialog box. I also pass a callback function in params to return the results.
Here is a fiddle demo which shows the concept: http://jsfiddle.net/Quango/5bxbsLt6/
Passing the observable boolean to invoke the dialog doesn't feel right, but it's the only working solution I have. The only other idea I had was to use ko-postbox to create a publish/subscribe function.
It feels like there should be a way to invoke actions, e.g. component.Show() ?
I think the answer here is that there isn't a better way. To communicate from a parent viewmodel to the component, pass an observable value, and then use that directly or subscribe to changes in the component.
I will put a suggestion on the Knockout github project to consider some form of interface.
Is there a way to bind an event callback so that it's called for all instances of Magnific Popup? On a site I'm building several elements have fixed position and "jump" when the main browser scrollbar disappears. I want to set a callback to add padding for those elements before any popup is opened, and remove the padding when the popup is closed. I don't want to re-use the callbacks every time I initialize Magnific Popup – I'd rather set one set of callbacks that is run every time Magnific opens and closes a popup.
My first thought was to use event delegation and bind pretty high in the document tree. I was trying to bind to the mfpOpen event and listen on the BODY tag, but it doesn't seem like the event bubbles. Is there another solution?
Events are dispatched only on target element or on document (if target element is not present).
But you may override open function globally using prototype, e.g.:
$.magnificPopup.instance.open = function(data) {
console.log('before open anything');
$.magnificPopup.proto.open.call(this,data);
console.log('after open anything');
};
You may do the same thing with close function (it doesn't have any arguments).
