Navigate to particular component only after filling required input fields












2















I have components called demo, demo component have 3 input fields and an button.Like this:



enter image description here



After clicking button(i,e submit) i am navigating to another component called home.This scenario is working fine for me, But i have added some validation for first/last-name and email.



If the user enters all the required input fields then only it as to navigate to another component (i,e home).But it is navigating without entering/validating the required input fields.



While surfing i got some examples:



1) Example 1

2) Example 2



But these are for template-driven forms. I am using reactive forms.



Here is the Stakcblitz DEMO.

  • <button mat-raised-button [routerLink]="['../home']" type="submit" color="primary" [disabled]="!addForm.valid" (click)="onaddCustomer()">Submit</button> .. should work ? i.e. you can disable the Submit button till the form is valid.

make the button disabled since the form is valid



<button mat-raised-button  type="submit" color="primary" [disabled]="!addForm.valid"  (click)="onaddCustomer()">Submit</button>


and navigate in the click function



onaddCustomer(){

this.router.navigate(['/home']);

}


with out using [disabled]



check whether form valid or not in your click function



<button mat-raised-button  type="submit" color="primary"   (click)="onaddCustomer()">Submit</button>


and in click function



onaddCustomer(){

if(this.addForm.valid){
this.router.navigate(['/home']);
}
}

Simply disable the submit button till the form is valid, no other change is required.



Like that [disabled]="!addForm.valid"i.e. in your case:-



<button mat-raised-button [routerLink]="['../home']" type="submit" color="primary" [disabled]="!addForm.valid" (click)="onaddCustomer()">Submit</button>


OR



If you don't want to disable the button then remove [routerLink]="['../home']" from the button and in the component method add a condition for validation like:-



onaddCustomer(){



if (this.addForm.invalid) { return; }



this.router.navigate(['/home']);



}

  • Then just remove the [routerLink]="['../home']" from button and write it on component like:- onaddCustomer(){ // Stop if invalid if (this.addForm.invalid) { return; } this.router.navigate(['/home']); }

Disabling just submit button may cause problems if you hit enter in an input as it submits the form. If you structured your form properly (as a reactive form), you could use a function on form submit.



<form [formGroup]="yourReactiveFormGroup" (ngSubmit)="onSubmit()">
...
</form>


and in onSubmit() function:



onSubmit() {

// Stop if invalid
if (this.yourReactiveFormGroup.invalid) {
return;
}

this.router.navigate(['/your-route']);
}

    Disabling just submit button may cause problems if you hit enter in an input as it submits the form. If you structured your form properly (as a reactive form), you could use a function on form submit.



    <form [formGroup]="yourReactiveFormGroup" (ngSubmit)="onSubmit()">
    ...
    </form>


    and in onSubmit() function:



    onSubmit() {

    // Stop if invalid
    if (this.yourReactiveFormGroup.invalid) {
    return;
    }

    this.router.navigate(['/your-route']);
    }
