angular - Angular2: Form values not picked up -


i've created form inside ngoninit() method:

this.cardform = this.fb.group({     card_number: ['', validators.required],     holdername: ['', validators.required],     expiry: ['', validators.required],     cvc: ['', validators.required],     address_line1: ['', validators.required],     address_line2: ['', validators.required],     address_city: ['', validators.required],     address_state: ['', validators.required],     address_zip: ['', validators.required],     address_country: ['', validators.required]   });

on template:

<form [formgroup]="cardform" novalidate="novalidate">   <div class="form-group">     <label for="cardnumber">card number</label>     <input        type="text"       name="cardnumber"       class="input-transparent form-control"       formcontrolname="card_number"       data-mask="9999-9999-9999-9999"       placeholder="____-____-____-____"       required="required">  </div>

when i'm trying values of form, card_number, cvc , expiry empty.

enter image description here

as can see, cardform have several fields. i've binded in 2 <from> tags on tamplate.

so, card_number, holdername, expiry , cvc binded on first form:

<form [formgroup]="cardform" novalidate="novalidate">   <input      id="card_number"     type="text"     name="card_number"     class="input-transparent form-control"     formcontrolname="card_number"...

and other ones binded on second <form> tag:

<form [formgroup]="cardform" novalidate="novalidate">   <input      id="address_line1"     type="text"     name="address_line1"     class="input-transparent form-control"     formcontrolname="address_line1"...

i've tried create 2 formgroup, , bind them each form on template:

this.cardform = this.fb.group({     card_number: ['', validators.required],     holdername: ['', validators.required],     expiry: ['', validators.required],     cvc: ['', validators.required] }); this.detailsform = this.fb.group({     address_line1: ['', validators.required],     address_line2: ['', validators.required],     address_city: ['', validators.required],     address_state: ['', validators.required],     address_zip: ['', validators.required],     address_country: ['', validators.required]   });

on template:

<form [formgroup]="cardform" novalidate="novalidate"> <form [formgroup]="detailsform" novalidate="novalidate">

nevertheless:

enter image description here

for similar case used patchvalue or setvalue of particular formgroup object.

for e.g in ngoninityou can set:

 this.cardform.patchvalue({card_number: 'foobar'});

again, if value changes can update in similar way.

carddetailschanged(val){    this.cardform.patchvalue({card_number: val}); }
