I have this simple select that is generating the numbers from an array in the component.ts file and I want to make it so that when the user clicks a number on the dropdown list, a variable in that .ts file is updated (inputBoxes) and that many input boxes will be displayed.
in my html file I have
component.html
<p>How many words will you be using?</p>
<select>
<option *ngFor="let num of wordCount" (click)="updateInputBoxes(num)">{{num}}</option>
</select>
component.ts
public wordCount: Array<number> = [1,2,3,4,5];
public inputBoxes: number;
constructor() { }
ngOnInit(): void {
}
updateInputBoxes(num: number) {
this.inputBoxes = num;
}
This is what I was trying so far but the updateInputBoxes function doesn't even execute. How do I know which number is selected while sending that selected number as a parameter to the function updateInputBoxes?
You need to add change method in select tag then pass the event to get current selected option vaule in ts file.
Try this code to get selected option value :
HTML CODE
<select (change)="updateInputBoxes($event)">
<option value="">
Select count
</option>
<option *ngFor="let num of wordCount" value={{num}}>{{num}}</option>
</select>
TS CODE
updateInputBoxes(event) {
this.inputBoxes = event.target.value;
}
If you want to call method after select each options you need to use change event in select tag not option tag.
And to pass selected value to your methods you can use template reference like this:
<select #selectList (change)="updateInputBoxes(selectList.value)">
<option *ngFor="let num of wordCount" [value]="num">{{num}}</option>
</select>
Here is working sample I created: StackBlitzLink
But if you only need selected value of selectbox there is no need to call fanction just use [(ngModel)]="inputBoxes" like this:
<select [(ngModel)]="inputBoxes">
<option *ngFor="let num of wordCount" [value]="num">{{num}}</option>
</select>
Use template driven or reactive forms for this.
The template driven version looks like this:
<select name="countControl" [(ngModel)]="inputBoxes">
<option *ngFor="let wordCount of wordCounts" [ngValue]="wordCount">
{{ wordCount }}
</option>
</select>
Docs: https://angular.io/api/forms/SelectControlValueAccessor#description
I need to set a default value/placheholder in my select option, it looks easy to do but I wasn't able to do it. I've tried different things but I got the same result.
<select class="form-control border custom-select" [compareWith]="compareFn"
[(ngModel)]="skill.category">
<option selected disabled="disabled">Chose a category...</option>
<option *ngFor="let cat of categories" [ngValue]="cat"
[hidden]="cat.id === 1">{{cat.name}}</option>
</select>
compareFn(c1: Skill, c2: Skill): boolean {
return c1 && c2 ? c1.id === c2.id : c1 === c2;
}
My output is something like this:
[CATEGORY id=1] default //I want this to be totaly hidden (id=1 hidden)
dropdown {
[Chose a category...]
[CATEGORY id=2]
[CATEGORY id=3]
[CATEGORY id=4]
...
} end dropdown
To achieve expected result, use slice pipe
slice: 1 - if the value to be removed is always first option
<select class="form-control border custom-select">
<option selected disabled="disabled">Chose a category...</option>
<option *ngFor="let cat of categories| slice:1" [ngValue]="cat">
{{cat.name}}</option>
</select>
code reference - https://stackblitz.com/edit/angular-ay8zzk
Please refer this link for more details on Slice Pipe - https://angular.io/api/common/SlicePipe
in template you can in many ways, one more is:
<select class="form-control border custom-select" [compareWith]="compareFn"
[(ngModel)]="skill.category">
<mat-label>Chose a category...</mat-label>
<ng-container *ngFor="let cat of categories" >
<option *ngIf="cat.id !== 1" [ngValue]="cat">{{cat.name}}</option>
</ng-container>
</select>
use mat-label if the value od the disabled option is not a valid option,
the user must not be able to select a not valid option
do you really need the value of the selected to be the entire object?
or better removing before template
http.get<cat[]>('url').pipe(
map(list => list.filter(one => one.id !== 1))
).subs...
or even better removing from query in the database
I'd suggest not sending down the result for ID: 1 as you will not be utilizing it. Component would be something like:
import { Component } from "#angular/core";
#Component({
selector: "app-root",
templateUrl: "./app.component.html",
styleUrls: ["./app.component.css"]
})
export class AppComponent {
title = "CodeSandbox";
category = 0;
categories = [
{ id: 2, name: "Opel" },
{ id: 3, name: "Mazda" },
{ id: 4, name: "BMW" }
];
}
Template:
<select class="form-control border custom-select" [(ngModel)]="category">
<option selected disabled="disabled" [value]="0">Chose a category...</option>
<option *ngFor="let cat of categories" [value]="cat.id">{{cat.name}}</option>
</select>
I'm trying to do a select operation with default value set for my edit page. However, it's not showing in select box
<select name=moduleId [(ngModel)]="moduleName" >
<option value="{{model.moduleId}}" selected>{{moduleName}}</option>
<option *ngFor="let accss of access" value="{{accss.moduleId}}">{{accss.moduleName}}</option>
</select>
showing like this default value is right below in options.
Remove this value="{{model.moduleId}}" to value="{{moduleName}}"
<select name='moduleId' [(ngModel)]="moduleName">
<option value="{{moduleName}}" selected>{{moduleName}}</option>
<option *ngFor="let accss of access" value="{{accss.moduleId}}">{{accss.moduleName}}</option>
</select>
and in component add object as
access = [{
moduleId: 1,
moduleName: 'abc'
}, {
moduleId: 2,
moduleName: 'def'
}];
moduleName = 'Select';
The problem might be value in options change to [value] attribute binding
<select name=moduleId [(ngModel)]="moduleName" >
<option *ngFor="let accss of access" [value]="{{accss.moduleId}}">{{accss.moduleName}}</option> // change to this
</select>
COMPONENT
export class Component {
moduleName: any = <yourselecteddefaut>;
}
I'd like to bind a select element to a list of objects -- which is easy enough:
#Component({
selector: 'myApp',
template:
`<h1>My Application</h1>
<select [(ngModel)]="selectedValue">
<option *ngFor="#c of countries" value="c.id">{{c.name}}</option>
</select>`
})
export class AppComponent{
countries = [
{id: 1, name: "United States"},
{id: 2, name: "Australia"}
{id: 3, name: "Canada"},
{id: 4, name: "Brazil"},
{id: 5, name: "England"}
];
selectedValue = null;
}
In this case, it appears that selectedValue would be a number -- the id of the selected item.
However, I'd actually like to bind to the country object itself so that selectedValue is the object rather than just the id. I tried changing the value of the option like so:
<option *ngFor="#c of countries" value="c">{{c.name}}</option>
but this does not seem to work. It seems to place an object in my selectedValue -- but not the object that I'm expecting. You can see this in my Plunker example.
I also tried binding to the change event so that I could set the object myself based on the selected id; however, it appears that the change event fires before the bound ngModel is updated -- meaning I don't have access to the newly selected value at that point.
Is there a clean way to bind a select element to an object with Angular 2?
<h1>My Application</h1>
<select [(ngModel)]="selectedValue">
<option *ngFor="let c of countries" [ngValue]="c">{{c.name}}</option>
</select>
StackBlitz example
NOTE: you can use [ngValue]="c" instead of [ngValue]="c.id" where c is the complete country object.
[value]="..." only supports string values
[ngValue]="..." supports any type
update
If the value is an object, the preselected instance needs to be identical with one of the values.
See also the recently added custom comparison https://github.com/angular/angular/issues/13268
available since 4.0.0-beta.7
<select [compareWith]="compareFn" ...
Take care of if you want to access this within compareFn.
compareFn = this._compareFn.bind(this);
// or
// compareFn = (a, b) => this._compareFn(a, b);
_compareFn(a, b) {
// Handle compare logic (eg check if unique ids are the same)
return a.id === b.id;
}
This could help:
<select [(ngModel)]="selectedValue">
<option *ngFor="#c of countries" [value]="c.id">{{c.name}}</option>
</select>
You can do this too without the need to use [(ngModel)] in your <select> tag
Declare a variable in your ts file
toStr = JSON.stringify;
and in you template do this
<option *ngFor="let v of values;" [value]="toStr(v)">
{{v}}
</option>
and then use
let value=JSON.parse(event.target.value)
to parse the string back into a valid JavaScript object
It worked for me:
Template HTML:
I added (ngModelChange)="selectChange($event)" to my select.
<div>
<label for="myListOptions">My List Options</label>
<select (ngModelChange)="selectChange($event)" [(ngModel)]=model.myListOptions.id >
<option *ngFor="let oneOption of listOptions" [ngValue]="oneOption.id">{{oneOption.name}}</option>
</select>
</div>
On component.ts:
listOptions = [
{ id: 0, name: "Perfect" },
{ id: 1, name: "Low" },
{ id: 2, name: "Minor" },
{ id: 3, name: "High" },
];
An you need add to component.ts this function:
selectChange( $event) {
//In my case $event come with a id value
this.model.myListOptions = this.listOptions[$event];
}
Note:
I try with [select]="oneOption.id==model.myListOptions.id" and not work.
============= Another ways can be: =========
Template HTML:
I added [compareWith]="compareByOptionId to my select.
<div>
<label for="myListOptions">My List Options</label>
<select [(ngModel)]=model.myListOptions [compareWith]="compareByOptionId">
<option *ngFor="let oneOption of listOptions" [ngValue]="oneOption">{{oneOption.name}}</option>
</select>
</div>
On component.ts:
listOptions = [
{ id: 0, name: "Perfect" },
{ id: 1, name: "Low" },
{ id: 2, name: "Minor" },
{ id: 3, name: "High" },
];
An you need add to component.ts this function:
/* Return true or false if it is the selected */
compareByOptionId(idFist, idSecond) {
return idFist && idSecond && idFist.id == idSecond.id;
}
Just in case someone is looking to do the same using Reactive Forms:
<form [formGroup]="form">
<select formControlName="country">
<option *ngFor="let country of countries" [ngValue]="country">{{country.name}}</option>
</select>
<p>Selected Country: {{country?.name}}</p>
</form>
Check the working example here
In app.component.html:
<select type="number" [(ngModel)]="selectedLevel">
<option *ngFor="let level of levels" [ngValue]="level">{{level.name}}</option>
</select>
And app.component.ts:
import { Component } from '#angular/core';
#Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
levelNum:number;
levels:Array<Object> = [
{num: 0, name: "AA"},
{num: 1, name: "BB"}
];
toNumber(){
this.levelNum = +this.levelNum;
console.log(this.levelNum);
}
selectedLevel = this.levels[0];
selectedLevelCustomCompare = {num: 1, name: "BB"}
compareFn(a, b) {
console.log(a, b, a && b && a.num == b.num);
return a && b && a.num == b.num;
}
}
For me its working like this, you can console event.target.value.
<select (change) = "ChangeValue($event)" (ngModel)="opt">
<option *ngFor=" let opt of titleArr" [value]="opt"></option>
</select>
The key is to use a two way binding in the select via [(ngModel)] and use [ngValue] in each option.
You can even have a default null option and it works with Angular 12.
<select name="typeFather" [(ngModel)]="selectedType">
<option [ngValue]="null">Select a type</option>
<option *ngFor="let type of types" [ngValue]="type">{{type.title}}</option>
</select>
That approach is always going to work, however if you have a dynamic list, make sure you load it before the model.
You Can Select the Id using a Function
<option *ngFor="#c of countries" (change)="onchange(c.id)">{{c.name}}</option>
Create another getter for selected item
<form [formGroup]="countryForm">
<select formControlName="country">
<option *ngFor="let c of countries" [value]="c.id">{{c.name}}</option>
</select>
<p>Selected Country: {{selectedCountry?.name}}</p>
</form>
In ts :
get selectedCountry(){
let countryId = this.countryForm.controls.country.value;
let selected = this.countries.find(c=> c.id == countryId);
return selected;
}
Also, if nothing else from given solutions doesn't work, check if you imported "FormsModule" inside of "AppModule", that was a key for me.
You can get selected value also with help of click() by passing the selected value through the function
<md-select placeholder="Select Categorie"
name="Select Categorie" >
<md-option *ngFor="let list of categ" [value]="list.value" (click)="sub_cat(list.category_id)" >
{{ list.category }}
</md-option>
</md-select>
use this way also..
<h1>My Application</h1>
<select [(ngModel)]="selectedValue">
<option *ngFor="let c of countries" value="{{c.id}}">{{c.name}}</option>
</select>
Attention Angular 2+ users:
for some reason, [value] does not work on elements. use [ngModel] instead.
<select [ngModel]="selectedCountry">
<option *ngFor="let country of countries" [value]="country">{{country.name}}</option>
</select>
Tested on Angular 11. I need an extra object 'typeSelected'. Pay attention I'm not using [(ngValue)] as other answers do:
<mat-select formControlName="type" [(value)]="typeSelected"
[compareWith]="typeComparation">
<mat-option *ngFor="let myType of allSurveysTypes" [value]="myType">
{{myType.title}}
</mat-option>
</mat-select>
//Declaration.
typeSelected: SurveyType;
...
//Assigning variable 'type' of object 'survey' to 'typeSelected'.
this.typeSelected = survey?.type;
...
//Function to compare SurveyType objects.
typeComparation = ( option, value ) => {
if (option && value) {
return option.id === value.id;
}
}
This code is very simple:
<select class="form-control" id="marasemaat" [(ngModel)]="fullNamePresentor"
[formControl]="stateControl" (change)="onSelect($event.target.value)">
<option *ngFor="let char of programInfo1;let i = index;"
onclick="currentSlide(9,false)"
value={{char.id}}>{{char.title + " "}} ----> {{char.name + " "+ char.family }} ---- > {{(char.time.split('T', 2)[1]).split(':',2)}}</option>
</select>
In Angular 1 I could select the default option for a drop down box using the following:
<select
data-ng-model="carSelection"
data-ng-options = "x.make for x in cars" data-ng-selected="$first">
</select>
In Angular 2 I have:
<select class="form-control" [(ngModel)]="selectedWorkout" (ngModelChange)="updateWorkout($event)">
<option *ngFor="#workout of workouts">{{workout.name}}</option>
</select>
How could I select a default option given my option data is:
[{name: 'arm'}, {name: 'back'}, {name:'leg'}] and my value I to default on on is back?
Add a binding to the selected property, like this:
<option *ngFor="#workout of workouts"
[selected]="workout.name == 'back'">{{workout.name}}</option>
If you assign the default value to selectedWorkout and use [ngValue] (which allows to use objects as value - otherwise only string is supported) then it should just do what you want:
<select class="form-control" name="sel"
[(ngModel)]="selectedWorkout"
(ngModelChange)="updateWorkout($event)">
<option *ngFor="let workout of workouts" [ngValue]="workout">
{{workout.name}}
</option>
</select>
Ensure that the value you assign to selectedWorkout is the same instance than the one used in workouts. Another object instance even with the same properties and values won't be recognized. Only object identity is checked.
update
Angular added support for compareWith, that makes it easier to set the default value when [ngValue] is used (for object values)
From the docs https://angular.io/api/forms/SelectControlValueAccessor
<select [compareWith]="compareFn" [(ngModel)]="selectedCountries">
<option *ngFor="let country of countries" [ngValue]="country">
{{country.name}}
</option>
</select>
compareFn(c1: Country, c2: Country): boolean {
return c1 && c2 ? c1.id === c2.id : c1 === c2;
}
This way a different (new) object instance can be set as default value and compareFn is used to figure out if they should be considered equal (for example if the id property is the same.
Add this Code at o position of the select list.
<option [ngValue]="undefined" selected>Select</option>
just set the value of the model to the default you want like this:
selectedWorkout = 'back'
I created a fork of #Douglas' plnkr here to demonstrate the various ways to get the desired behavior in angular2.
You Can approach this way:
<option *ngFor="let workout of workouts" [value]="workout.name">{{workout.name}}</option>
or this way:
<option *ngFor="let workout of workouts" [attr.value]="workout.name" [attr.selected]="workout.name == 'leg' ? true : null">{{workout.name}}</option>
or you can set default value this way:
<option [value]="null">Please Select</option>
<option *ngFor="let workout of workouts" [value]="workout.name">{{workout.name}}</option>
or
<option [value]="0">Please Select</option>
<option *ngFor="let workout of workouts" [value]="workout.name">{{workout.name}}</option>
Use index to show the first value as default
<option *ngFor="let workout of workouts; #i = index" [selected]="i == 0">{{workout.name}}</option>
According to https://angular.io/api/forms/SelectControlValueAccessor you
just need the following:
theView.html:
<select [compareWith]="compareFn" [(ngModel)]="selectedCountries">
<option *ngFor="let country of countries" [ngValue]="country">
{{country.name}}
</option>
</select>
theComponent.ts
import { SelectControlValueAccessor } from '#angular/forms';
compareFn(c1: Country, c2: Country): boolean {
return c1 && c2 ? c1.id === c2.id : c1 === c2;
}
Struggled a bit with this one, but ended up with the following solution... maybe it will help someone.
HTML template:
<select (change)="onValueChanged($event.target)">
<option *ngFor="let option of uifOptions" [value]="option.value" [selected]="option == uifSelected ? true : false">{{option.text}}</option>
</select>
Component:
import { Component, Input, Output, EventEmitter, OnInit } from '#angular/core';
export class UifDropdownComponent implements OnInit {
#Input() uifOptions: {value: string, text: string}[];
#Input() uifSelectedValue: string = '';
#Output() uifSelectedValueChange:EventEmitter<string> = new EventEmitter<string>();
uifSelected: {value: string, text: string} = {'value':'', 'text':''};
constructor() { }
onValueChanged(target: HTMLSelectElement):void {
this.uifSelectedValue = target.value;
this.uifSelectedValueChange.emit(this.uifSelectedValue);
}
ngOnInit() {
this.uifSelected = this.uifOptions.filter(o => o.value ==
this.uifSelectedValue)[0];
}
}
Fully fleshing out other posts, here is what works in Angular2 quickstart,
To set the DOM default: along with *ngFor, use a conditional statement in the <option>'s selected attribute.
To set the Control's default: use its constructor argument. Otherwise before an onchange when the user re-selects an option, which sets the control's value with the selected option's value attribute, the control value will be null.
script:
import {ControlGroup,Control} from '#angular/common';
...
export class MyComponent{
myForm: ControlGroup;
myArray: Array<Object> = [obj1,obj2,obj3];
myDefault: Object = myArray[1]; //or obj2
ngOnInit(){ //override
this.myForm = new ControlGroup({'myDropdown': new Control(this.myDefault)});
}
myOnSubmit(){
console.log(this.myForm.value.myDropdown); //returns the control's value
}
}
markup:
<form [ngFormModel]="myForm" (ngSubmit)="myOnSubmit()">
<select ngControl="myDropdown">
<option *ngFor="let eachObj of myArray" selected="eachObj==={{myDefault}}"
value="{{eachObj}}">{{eachObj.myText}}</option>
</select>
<br>
<button type="submit">Save</button>
</form>
You can Use that [ngModel] instead of [(ngModel)]and it is Ok
<select class="form-control" **[ngModel]="selectedWorkout"** (ngModelChange)="updateWorkout($event)">
<option *ngFor="#workout of workouts">{{workout.name}}</option>
</select>
You can do as above:
<select class="form-control"
[(ngModel)]="selectedWorkout"
(ngModelChange)="updateWorkout($event)">
<option *ngFor="#workout of workouts;
let itemIndex = index"
[attr.selected]="itemIndex == 0">
{{workout.name}}
</option>
</select>
In above code as you can see, selected attribute of the repeating option is set on checking index of the repeating loop of list. [attr.< html attribute name >] is used for setting html attribute in angular2.
Another approach will be setting model value in typescript file as :
this.selectedWorkout = this.workouts.length > 0
? this.workouts[0].name
: 'No data found';//'arm'
Add on to #Matthijs 's answer, please make sure your select element has a name attribute and its name is unique in your html template. Angular 2 is using input name to update changes. Thus, if there are duplicated names or there is no name attached to input element, the binding will fail.
I faced the same problem while using angular 11. But finally found a solution.
<option disabled selected value="undefined">Select an Option</option>
complete example with ngFor.
<select name="types" id="types" [(ngModel)]="model.type" #type="ngModel">
<option class="" disabled selected value="undefined">Select an Option</option>
<option *ngFor="let item of course_types; let x = index" [ngValue]="type.id">
{{ item.name }} </option>
</select>
Add binding property selected, but make sure to make it null, for other fields e.g:
<option *ngFor="#workout of workouts" [selected]="workout.name =='back' ? true: null">{{workout.name}}</option>
Now it will work
<select class="form-control" name='someting' [ngModel]="selectedWorkout" (ngModelChange)="updateWorkout($event)">
<option value="{{workout.name}}" *ngFor="#workout of workouts">{{workout.name}}</option>
</select>
If you are using form there should be name field inside select tag.
All you need to do is just add value to the option tag.
selectedWorkout value should be "back" , and its done.
If you don't want the 2-way binding via [(ngModel)], do this:
<select (change)="selectedAccountName = $event.target.value">
<option *ngFor="let acct of accountsList" [ngValue]="acct">{{ acct.name }}</option>
</select>
Just tested on my project on Angular 4 and it works! The accountsList is an array of Account objects in which name is a property of Account.
Interesting observation:
[ngValue]="acct" exerts the same result as [ngValue]="acct.name".
Don't know how Angular 4 accomplish it!
Step: 1 Create Properties declare class
export class Task {
title: string;
priority: Array<any>;
comment: string;
constructor() {
this.title = '';
this.priority = [];
this.comment = '';
}
}
Stem: 2 Your Component Class
import { Task } from './task';
export class TaskComponent implements OnInit {
priorityList: Array<any> = [
{ value: 0, label: '✪' },
{ value: 1, label: '★' },
{ value: 2, label: '★★' },
{ value: 3, label: '★★★' },
{ value: 4, label: '★★★★' },
{ value: 5, label: '★★★★★' }
];
taskModel: Task = new Task();
constructor(private taskService: TaskService) { }
ngOnInit() {
this.taskModel.priority = [3]; // index number
}
}
Step: 3 View File .html
<select class="form-control" name="priority" [(ngModel)]="taskModel.priority" required>
<option *ngFor="let list of priorityList" [value]="list.value">
{{list.label}}
</option>
</select>
Output:
You just need to put the ngModel and the value you want selected:
<select id="typeUser" ngModel="Advanced" name="typeUser">
<option>Basic</option>
<option>Advanced</option>
<option>Pro</option>
</select>
For me, I define some properties:
disabledFirstOption = true;
get isIEOrEdge(): boolean {
return /msie\s|trident\/|edge\//i.test(window.navigator.userAgent)
}
Then in the constructor and ngOnInit
constructor() {
this.disabledFirstOption = false;
}
ngOnInit() {
setTimeout(() => {
this.disabledFirstOption = true;
});
}
And in the template I add this as the first option inside the select element
<option *ngIf="isIEOrEdge" [value]="undefined" [disabled]="disabledFirstOption" selected></option>
If you allow to select the first option you can just remove the usage of the property disabledFirstOption
In my case, here this.selectedtestSubmitResultView is set with default value based on conditions and an variable testSubmitResultView must be one and same as testSubmitResultView. This indeed worked for me
<select class="form-control" name="testSubmitResultView" [(ngModel)]="selectedtestSubmitResultView" (ngModelChange)="updatetestSubmitResultView($event)">
<option *ngFor="let testSubmitResultView of testSubmitResultViewArry" [ngValue]="testSubmitResultView" >
{{testSubmitResultView.testSubmitResultViewName}}
</option>
</select>
For More Information,
testSubmitResultViewArry: Array<any> = [];
selectedtestSubmitResultView: string;
getTestSubmitResultViewList() {
try {
this.examService.getTestSubmitResultViewDetails().subscribe(response => {
if (response != null && response !== undefined && response.length > 0) {
response.forEach(x => {
if (x.isDeleted === false) {
this.testSubmitResultViewArry.push(x);
}
if (x.isDefault === true) {
this.selectedtestSubmitResultView = x;
}
})
}
});
} catch (ex) {
console.log('Method: getTestSubmitResultViewList' + ex.message);
}
}
I faced this Issue before and I fixed it with vary simple workaround way
For your Component.html
<select class="form-control" ngValue="op1" (change)="gotit($event.target.value)">
<option *ngFor="let workout of workouts" value="{{workout.name}}" name="op1" >{{workout.name}}</option>
</select>
Then in your component.ts you can detect the selected option by
gotit(name:string) {
//Use it from hare
console.log(name);
}
works great as seen below:
<select class="form-control" id="selectTipoDocumento" formControlName="tipoDocumento" [compareWith]="equals"
[class.is-valid]="this.docForm.controls['tipoDocumento'].valid &&
(this.docForm.controls['tipoDocumento'].touched || this.docForm.controls['tipoDocumento'].dirty)"
[class.is-invalid]="!this.docForm.controls['tipoDocumento'].valid &&
(this.docForm.controls['tipoDocumento'].touched || this.docForm.controls['tipoDocumento'].dirty)">
<option value="">Selecione um tipo</option>
<option *ngFor="let tipo of tiposDocumento" [ngValue]="tipo">{{tipo?.nome}}</option>
</select>
