Formarrayname angular 7 example

On February 7, 2019, many angular relec responsive forms of nesting I found everywhere for a solution that I could just copy and paste into my project, but without luck, so here is my attempt to provide it for the next poor soul stuck in my situation. I tried to keep the code as simple as possible. league_details: this.fb.group({: , : }) .fb.group = .fb.group({league_details: , : } (): {.fb.group ({team_name: , : this.fb.array ([.]} } } (): FormGroup { .fb.group({player_name: , player_number: });} <form [formgroup]=leagueForm><div class=form-header formgroupname=league_details><label> <input formcontrolname=name></label><label> <input formcontrolname=founder></label></div> formArrayName VITAL! <div formarrayname=teams><div class=teams *ngfor=let team of leagueForm.get('teams').controls; let teamIndex = index [formgroupname]=teamIndex><label> <input formcontrolname=team_name></label><!-- div with formArrayName='players' goes here (see below) --></div></div> Important, you have a wrap div with formArrayName. You also need to add players to your team's context. The notification in ngfor refers to the team variable defined in the ngFor loop above. You should also refer to this team when removing or adding players. It is also a way to reference fields for the <span> validation feature. <div formarrayname=players><div class=players *ngfor=let player of team.get('players').controls; let playerIndex=index [formgroupname]=playerIndex><label>Player Name <input formcontrolname=player_name> gt;<label>Player Number <input formcontrolname=player_number></label><span *ngif=player.get ('player_number').touched>Touched!</span></label></div></div> Add Team button formsArrayArrayName team team <button type=button (click)=addTeam()>Add</button> Add Team Add Team (Add Team) as a form line.push.push.team;} } When you add a player, you need to place the Add button just above the div that defines the formArrayName player and pass the team variables in the surrounding ngFor loop. <button type=button (click)=addPlayer (team)>Add Player</button> Player (Team) {team.get (Player).push (this.player); } See project on github: Each form array example shows how to use FormArray. FormArray allows you to dynamically add controls to responsive forms. This example performs a very simple task of dynamically adding/removing skills to employee forms. Application: 2. The latest version of 8 each. Anedjin 9, 10 each, and arousal 11 are FormArray </span></form>How to manage a collection of form controls from an angle. Controls can group form controls in the form of angles in aFormGroup, aFormControl, or other FormArray.We. One uses FormGroup and the other is FormArray. The difference is how they implement it. In FormGroup, the control is the property of the FormGroup. Each control is displayed as a pair of key values. In FormArray, controls become part of an array, so they are implemented as arrays, making it easier to add controls dynamically. FormArray Example allows us to dynamically build simple applications that can add new skills in people. First, you need to import the form array from the Angle Form module, using the FormArray import form array. { Form model technicality with form builder to build form models in form groups, form controls, form arrays, formBuilder}, build @angular/form models. Our form has two fields. the name of the man and his skill. Since a person can have more than one skill, we define the technology as FormArray. Constructor (personal fb:FormBuilder) {i.skillsForm = this.fb.group ({technology: this.fb.array ([]), next, Getter method technique () to return form array technique in technology: FormArray {returns this.skillsForm.get (technology) as FormArray. Because it is an array, you can use the push method to use a new skill. The new Skill() method returns the FormGroup.log ;D. [formGroup]=Use the technical form to bind the form to the technical model. The formControlName=name directive binds the name input element to the name of the technical form.<form [formgroup]=skillsForm (ngsubmit)=onSubmit()><label for=name>name</label><in put type=text id=name name=name formcontrolname=name><button type=submit>Submit</button> Bind form array to template, we bind a technical form array array to a div element using the form array name directive. Everything inside the div and div elements is now bound to the technical form array.<div formarrayname=skills>use div repeats each element of the ngFor technical FormArray. i=Index stores the index value of the array in the template local variable i. We use it to remove elements from the technical array.<div formarrayname=skills><div *ngfor=let skill of skills().controls; Each element under let i=index>Technology is FormGroup. </div></div></div></form>FormGroup does not have a name. The index of an element is automatically assigned as the name of the element. Therefore, bind the formgroup to the div element using formgroupName=i, the index of the pomarray.<div formarrayname=skills><div *ngfor=let skill of skills().controls; Let i=index><div [formgroupname]=i>Finally, add a control using the form controlName directive. <div formarrayname=skills><div *ngfor=let skill of skills().controls; let i=index><div [formgroupname]=i><input type=text formcontrolname=skill><input type=text formcontrolname=exp><button (click)=removeSkill(i)>remove</button> It also adds new technologies by passing through index I and finally removing the <button(click)=removeSkill(i)>removal and calling the </button>addSkills method. <button type=button (click)=addSkills()>Add</button> It's an angle form array example application RunningSource ponent.tsimport { component, Viewfile, ElementRef } '@angular/Core';Import {FormGroup, FormControl, FormBuilder} '@angular/Form' TemplateUrl: './ponent.html', styleUrls: ['/ponent.css.', [form.' css constructor (personal fb:FormBuilder) {i.skillsForm = i.fb.group ({technology: this.fb.array ([]) , get skill (): FormArray {returns this.skillsForm.get (technology) as FormArray.skillsForm.getush.push (i.newSkill()); console.log (i.skillForm.value); constructor (i.tech form.html<form [formgroup]=skillsForm (ngsubmit)=onSubmit()><label for=name>name</la bel><input type=text id=name name=name formcontrolname=name><div formarrayname=skills><<div *ngfor=let skills().controls; let i=index><< div [formgroupname]=i><input type=text formcontrolname=skill><input type=text formcontrolname=exp><button (click)=removeSkill(i)>Remove</button> <button type=subscription></button> <button type=button (click)=addSkills()></button>{{this.skillsForm.value | json}} reference summary in this tutorial , We have learned how to create a simple FormArray example application. In /Form'@angular, the {Reactivation Form Module} @NgModule ({Import: Post-Alarm Module, }) Export Class AppModule {}Basic Responsive Form Service Post-Form Understanding is used to manage the complex data entered by the user in the form. We'll focus on some of the useful services in the reactive form. Abstract control: A base class for controlling the behavior and properties of formgroups, form controls, and FormArray.FormBuilders. FormGroup: FormGroup is the top-level API that maintains the values, properties, and validation status of a group of abstract control instances.</div></div></div></form> gt;</div></div></div></div></div></div>It communicates with HTML form elements, such as input or selection tags, which handle individual form values and validation states. FormArray: The FormArray API maintains the value, properties, and validation status of an array of abstract control instances.ngSubmit: This event is called when you submit a form. Set reactive forms in each component HTML ponent.html <form [formgroup]=registrationForm (ngsubmit)=onSubmit()><button type=submit class=btn btn-danger btn-lg btn-block>Submit form</button></form>'@angular/Core' in responsive ponent.tsimport { components } settings; @angular {formbuilder, form array} from a form/form; @Component ({selector: 'app root', templateUrl: './app..html.html,' styleUrls: ['./ponent.css'} }) Export class AppComponent {constructor (public fb: FormBuilder) {} Registration Form = this.fb.group ({addDyna) MicElement: this.fb.array ([]) }) On-off () {Warning (JSON.stringify (this.registerForm.value) } } } } let's set up an HTML layout for nest form-creating. Use the following directive to synchronize nested formarrays to DOM elements in Angular.formArrayName.*ngFor: Structural guidelines provided by looping angles for all items in the collection. <form [formgroup]=regulationForm (ngsubmit)=onSubmit()><div class=group-gap formarrayname=add DynamicElement><h5 class=mb-3>Add Product</h5><div class=mb-3><button type=button class=btn btn-sm btn-success mb-3 btn-block (click)=addSuperPowers()>Add Item</button><ul class=subjectList><li *ngfor=let item of addDynamicMentEle.control let i = index><input type=text class=form-control [formcontrolname]=i></li></ul></div><<button type=submit If you understand class=btn btn-danger btn-lg btn-block>Submit Form</button></div></form>Dynamic form arrays, you can access dynamic element form controls by subdivusing the JavaScript getter method. Then assign a form array to form the control and make it an array. When this process is complete, add an item() function and push the dynamically generated form control to the AddDynamicElement array. Return additional dynamic elements () {this.registerForm.get ('Dynamic Eliso') as a form line} addItems() {this.addDynamicElement.push (this.fb.control(')) }}Let's check out the output.ponent.tsimport {component} in '@angular/core'; @angular formbuilders, form arrays, validator } from the form/form; @Component ({selector: 'App Root', TemplateUrl: './ponent.html.html styleUrls: ['./ponent.css'} }) Export class AppComponent {constructor (public FB: FormBuilder) {} Registration Form = e.fb.group ({addDynamicElement: this.fb.array ([]) }) Additional elements ().) {Returns this .regulationForm.get ('AdDynamicElement') Pom-alay } addItems () {i.addDynamicElement.push (this.fb.control ('')} On-off() { Warning (JSON.stringify(.registerForm.value)} } }
