I am trying to make a structure of some sort that has key value pairs where the key is an identifier like 'equals' and the values are the unicode equivalent html like '\='.<\/i>
export enum Symbols {
equals = '\u003D'
}
To have the enum accessible within the component, you must declare a property, like you did, but instead of declaring it of type<\/em> Symbols<\/code> (using
:<\/code> ), you should assign
Symbol<\/code> to it (using
=<\/code> ).<\/i>
import { Component } from '@angular/core';
export enum Symbols {
equals = '\u003D',
notEquals = '!='
}
@Component({
selector: 'my-app',
template: `
<p>
Having the name as label and symbol as value:
<select>
<option *ngFor="let symbol of keys(symbols)" [ngValue]="symbols[symbol]">{{symbol}}</option>
</select>
</p>
<p>
Having the symbol as label and name as value:
<select>
<option *ngFor="let symbol of keys(symbols)" [ngValue]="symbol">{{symbols[symbol]}}</option>
</select>
</p>
`
})
export class AppComponent {
keys = Object.keys;
symbols = Symbols;
}
You can also use the keyvalue pipe as well, it makes your life easier.
<p *ngFor="let enum of TestEnum | keyvalue">
{{ enum.key }} - {{ enum.value}}
</p>
