Mixing
dynamically adding # attribute in angular 6 element
0
I have following code in one of my templates:
<ion-col text-center *ngFor="let shape of data.items[0].expandItems | slice:0:4; let i=index">
<a #btn{{shape.value}} class="item item-text-wrap notselected" (click)="toggleButtonShape(shape)">
<img src="{{shape.url}}">
<p>{{shape.title}}</p>
</a>
</ion-col>
And the code in my corresponding .ts file is:
toggleButtonShape(shape) {
shape.isChecked = !shape.isChecked;
if(shape.value === 'BR') {
if (shape.isChecked === true) {
this.removeClass('notselected', this.btnBR);
} else {
this.addClass('notselected', this.btnBR);
}
} }
addClass(className?: string, element?: any) {
this.renderer.addClass(element.nativeElement, className);
}
removeClass(className?: string, element?: any) {
this.renderer.removeClass(element.nativeElement, className);
}
The problem is, when either of the above mentioned functions are executed, the element parameter is undefined. I have declared all the @ViewChilds().
