Steps for implementing nfIF with a boolean outcome involving three conditions

Is there a way to display the same HTML code based on a condition without repeating it multiple times?

I've attempted using ngIF, but it requires me to duplicate the HTML snippet three times.

<div *ngIf="data.dataUm"><dt>Data:</dt><dd>{{data.dataImplementacao|DateMoment}}</dd></
div>
<div *ngIf="data.dataDois"><dt>Data:</dt><dd>{{data.dataImplementacao|DateMoment}}</dd></
div>
<div *ngIf="data.dataTres"><dt>Data:</dt><dd>{{data.dataImplementacao|DateMoment}}</dd></
div>

So, is there a way to implement a condition in order to avoid repeating the same HTML code?

Answer №1

Your HTML appears to be redundant. A suggestion is to consolidate your HTML into a single snippet and utilize the logical OR operator || within your *ngIf. This approach will yield the same outcome:

<div *ngIf="data.dataUm || data.dataDois || data.dataTres">
    <dt>Data:</dt>
    <dd>{{data.dataImplementacao|DateMoment}}</dd>
</div>

Answer №2

To trigger an action only when all conditions are true, create a single statement using && to separate the three conditions. If you want it to be triggered if at least one condition is true, use ||.

The main distinction with these statements compared to your current code is that it will only execute once when all conditions are satisfied. Your current code would execute each time any of the conditions are met.
