I'm starting with Angular 6, I need to call a method in HTML but I do not know how to do it. The only way I have found is to assign it to an event but what I want is for the method to be executed only without the need to click on a button or something similar. How do I invoke the method in the html?
You can make use of a life cycle hook, which is invoked after Angular has initialized all the properties of a data-bound policy. Define a ngOnInit() as a method to handle any additional initialization tasks.
This helps you to execute important functions or methods that are required when starting a component in Angular.
Source: Angular.io
Example
ngOnInit()
{
//Declaracion de variables para activar clases nativas de Bootstrap = Active.
this.claseInventario='nav-link active';
//Declaración de variables del titulo de cada componente
this.tituloComponente = 'Inventario';
//Evalumos formulario
this.evaluated = true;
//Iniciamos el validador cuando inicie el controlador del componente
this.registrarInventario = this.formBuilder.group({
producto_inventario: ['', [Validators.required]],
costo_inventario: ['', [Validators.required]],
cantidad_inventario: ['', [Validators.required]],
proveedor_inventario: ['', [Validators.required]],
vencimiento_inventario: [null, []],
orden_inventario: ['', []],
invima_inventario: ['', []],
lote_inventario: ['', [Validators.required]],
bodega_inventario: ['', [Validators.required]],
ubicacion_inventario: ['', [Validators.required]],
observacion_inventario: ['', []]
});
};
If it helps, you let me know, but also ...
