Ngx-bootstrap: Popover close from within the element itself

[jdeblander]

I want to create a popover with a template and within that template a button "close" wich closes this popover.
I have the following code:

<button type="button" class="btn btn-primary" [popover]="options" placement="bottom" container="body">
    TemplateRef binding
</button>

<template #options>
    Just another template
    <div class="popover-footer">
        <button type="button" class="btn btn-default" (click)="options.hide()">Close</button>
    </div>
</template>

This gives me following error:

self.parentView._TemplateRef_6_4.hide is not a function

So I guess the id options isn't on the correct element.
Can someone please explain how I can make this work?

You got this error because you are trying to call a method that your component does not know. The binding is on the element that hold the popover directive and the template reference, not the template itself. I'm not sure you can do this with the current version.

So there isn't any option I could add that "close" button to the popover at the moment?

Create function for that click event and in component use @ViewChild.

@GuskiS to hide a popover properly, you must use the hide function from the component loader class. Again, the binding is the element that hold the popover directive so is the hide function.

In order to have access to the component loader class, the template element needs to hold the popover directive, eg:

<template
  popoverTitle="Template ref content inside"
  popover=""
  #pop="bs-popover">
  Binding popover inside itself
  <button (click)="hide()">Hide</button>
</template>

with

@ViewChild('pop') pop: PopoverDirective;

...

public hide() {
   this.pop._popover.hide();
}

then you do have a access to the component loader API but for some reason you still don't have the component reference which is needed to close the popover as in

// component-loader.class.ts
  public hide(): ComponentLoader<T> {
    if (this._componentRef) {
      this.onBeforeHide.emit(this._componentRef.instance);
      this._viewContainerRef.remove(this._viewContainerRef.indexOf(this._componentRef.hostView));
      this._componentRef = null;

      if (this._contentRef.viewRef) {
        this._viewContainerRef.remove(this._viewContainerRef.indexOf(this._contentRef.viewRef));
        this._contentRef = null;
      }

      this._componentRef = null;
      this.onHidden.emit();
    }
    return this;
  }

should be as simple as

<button type="button" #pop="bs-popover" class="btn btn-primary" [popover]="options" placement="bottom" container="body">
    TemplateRef binding
</button>

<template #options>
    Just another template
    <div class="popover-footer">
        <button type="button" class="btn btn-default" (click)="pop.hide()">Close</button>
    </div>
</template>

[ruffiem]

Funny I didn't try to recall #pop into the template but yeah, that should work 👍

[pgeyman]

@valorkin How can I achieve the same as your example but where the template is defined in another component and passed as a TemplateRef via a service?

<button type="button" class="btn" [ngClass]="actionBarItem.additionalClasses"
        [popover]="actionBarItem.popoverContent" 
        [popoverTitle]="actionBarItem.popoverTitle" placement="bottom">
    {{actionBarItem.text}}
    <span class="caret"></span>
</button>

public popoverContent: TemplateRef<any>;

@valorkin would it still be possible in your case if the trigger button actually live in anther child component

For example in the main template component, we have a presentational component for the button
<my-button [title]="Open "></my-button> which has this context

<button type="button" #pop="bs-popover" class="btn btn-primary" [popover]="options" placement="bottom" container="body">
    TemplateRef binding
</button>

Since the templateRef #options does not live on the same component so not sure how it can be linked and work together. Thanks

it should be possible to pass context that is going to used to render the template inside popover as [ngTemplateOutletContext]

I don't know how but the requested thing works versions before 2.0.0-beta.3.

should be as simple as

<button type="button" #pop="bs-popover" class="btn btn-primary" [popover]="options" placement="bottom" container="body">
    TemplateRef binding
</button>

<template #options>
    Just another template
    <div class="popover-footer">
        <button type="button" class="btn btn-default" (click)="pop.hide()">Close</button>
    </div>
</template>

I am calling a component within the template , how can i close the popup from within?
navbar.component.html

<li class="d-flex  flex-column ">
<a href="javascript:void(0);" class="chat" id ="chat" aria-label="chat-label" role="button" 
tabindex="0" [popover]="mypopover" placement="bottom" [outsideClick]="false" label="Click">
</a>
</li>
<ng-template #mypopover>
                <app-mycomponent></app-mycomponent>    
            </ng-template>

In Child or app-mycomponent
// HTML
Cancel
// TS
@Output() onPopoverCancel = new EventEmitter();
close_Popover() {
this.onPopoverCancel.emit();
return false;
}

In Parent Component
// HTML
tabindex="0" #pop="bs-popover" [popover]="mypopover" placement="bottom" [outsideClick]="false" label="Click">
