I will Look at the link, Thank you so much for the big Help.
Hello,
I do not know where
output at console this massage username: not updated
comes from, maybe name=“username” or maybe [(ngModel)]=“username”.
This is always a problem with same naming, also look to data: any = {}; is an object, var data = JSON.stringify({username: this.data.username}); is a json string. Both names data, different type. This is imho not really easy maintable and this combined with var. Happy debugging.
Best regards
