Struggling to transfer information between different components?

I recently implemented a delete button functionality in my project to remove elements when clicked, but I'm facing an issue where the input decorator is not properly receiving data for deletion. When I console log, it shows that the array is empty which adds to the confusion. This scenario highlights a challenge I am currently tackling in a small project. Any insights on how to improve the usage of input decorators and best practices would be highly appreciated.

    ChildComponent:

    public valuesCheck: string [] = [];

    @Input() valuesFilter: string[] = [];
    public deleteClick(){
      let chipValue = string [] = [];
      this.valuesCheck = this.valuesFilter = chipValue;

      chipValue.splice(0,1);
    }

    Parent Component:
    public filters: CFilter[] | undefined;

    Parent HTML:
    <app-filter-chip  [valuesFiter] = "chipValue">
    <app-filter-chip>

    Child HTML:
    <div class="chip>
    <button class="closebtn" (click)="deleteClick()">
    <div>

     

Answer №1

Here are a few issues to address:

  1. There is a typo in valuesFilter, it should be corrected to valuesFiter.

  2. The variable chipValue needs to be defined as a component's variable.

You can view an example of this problem here: stackblitz

Answer №2

By implementing the Output Emitter Approach, you are enabling your child component to remove data directly from the parent component. This method allows for seamless communication and data management between the two components.
