I want to send a different parameter to the $event in the function:
<div class='col-sm'>
<label class="col-3 col-form-label">Origen</label>
<div class="col-4">
<select [(ngModel)]="dana" class="form-control"
(ngModelChange)="filterFor($event)"required>
<option *ngFor="let dano of danos"
[value]="dano.comment">{{dano.make}}
</option>
</select>
</div>
</div>
I would like to send the parameter in the function filterFor call:
<div class='col-sm'>
<label class="col-3 col-form-label">Origen</label>
<div class="col-4">
<select [(ngModel)]="dana" class="form-control"
(ngModelChange)="filterFor(dano.tipo)"required>
<option *ngFor="let dano of danos"
[value]="dano.comment">{{dano.make}}
</option>
</select>
</div>
</div>
Fails:
error TS2551: Property 'dano' does not exist on type 'ComunidadFiltracionesComponent'. Did you mean 'danos'? .
Do you know the format of the parameter so that it accepts it? Thanks in advance
Expand the query:
I have an object with different parameters:
let car = [ {'make': 'Ford', 'comment': 'The vehicle has a heavy internal combustion engine....'}];
In dropdown (ngFor), when the customer selects the make of the car, we take the comment variable.
If I want to compare vehicles:
if (dana == 'The vehicle has a heavy internal combustion engine....'){
this.quality = 'goog';
}
To find out which brand the client has entered, I have to compare through the comment (too long). I want to compare by the brand variable:
if (dana == 'Ford'){
this.quality = 'goog';
}
See in stackblitz : https://angular-ivy-mu5mrh.stackblitz.io/
if you use (ngModelChange)="filterFor($event)" in your function filterFor you received the [value] of the option selected.
if you use as value [value]="dano.make"
You can use some like
filterFor(value:any){
this.data=value; //<--if not use [(ngModel)] else [ngModel]
//don't forget equal the variable to value
const dano=this.datos.find(x=>x.make==value)
console.log(dano) //<--here you has the whole object
//you can, e.g.
if (value=='Ford')....
//or
if (dano.comment=='The vehicle has a heavy internal..')...
}
the issue in your code is that your'e trying to access dano variable which is out of the loop scope and hence isn't being recognized
