Tips for sending a String[] to my Angular 2 HTML template

In the export class of my component, I have a string array variable declared like this;

 barChartLabel:string[] = ['2006', '2007', '2008', '2009', '2010', '2011', '2012'];

To display this on the screen in my HTML template, I use the following code:

{{barChartLabel}} 

However, when I try to pass it as a parameter value, it fails, as shown below:

 <mychart [chartLabelObject]="[{{barChartLabel}}]"></mychart>

Do you have any idea what mistake I might be making?

Answer №1

It seems like your goal is to pass data to a child component called "mychart".

In the TypeScript file of your child component:

import { Input } from '@angular/core';

export class AppComponent {

@Input() chartLabelObject:string[];

}

In the parent's HTML file:

<app-craftinput [chartLabelObject]="barChartLabel"></app-craftinput>
