Angular 5 Button Submit On Enter Key Press

Question

I have an Angular 5 form application using all the usual models but on the forms I want the form to submit without having to physically click on the 'Submit' button.

I know it's normally as easy as adding type=submit to my button element but it does not seem to be working at all.

I don't really want to call an onclick function just to get it working. Can anyone suggest anything that I may be missing.

<form (submit)="search(ref, id, forename, surname, postcode)" action="#">
  <mat-card>
    <mat-card-title class="firstCard">Investor/Adviser search</mat-card-title>
    <mat-card-content>
      <p *ngIf="this.noCriteria" class="errorMessage">Please enter search criteria.</p>
      <p *ngIf="this.notFound" class="errorMessage">No investor's or adviser's found.</p>
        <mat-form-field>
          <input matInput id="invReference" placeholder="Investor/Adviser reference (e.g. SCC/AJBS)" #ref>
        </mat-form-field>
        <mat-form-field>
          <input matInput id="invId" placeholder="Investor/Adviser ID" type="number" #id>
        </mat-form-field>
        <mat-form-field>
          <input matInput id="invForname" placeholder="Forename" #forename>
        </mat-form-field>
        <mat-form-field>
          <input matInput id="invSurname" placeholder="Surname" #surname>
        </mat-form-field>
        <mat-form-field>
          <input matInput id="invPostcode" placeholder="Postcode" #postcode>
        </mat-form-field>
    </mat-card-content>
    <mat-card-footer>
      <button mat-raised-button type="submit" class="successButton" id="invSearch" title="Click to perform search.">Search</button>
    </mat-card-footer>
  </mat-card>
</form>

Solution 1

You could also use a dummy form arround it like:

<mat-card-footer>
<form (submit)="search(ref, id, forename, surname, postcode)" action="#">
  <button mat-raised-button type="submit" class="successButton" id="invSearch" title="Click to perform search." >Search</button>
</form>
</mat-card-footer>

the search function has to return false to make sure that the action doesn't get executed.
Just make sure the form is focused (should be when you have the input in the form) when you press enter.

Solution 2

try use keyup.enter or keydown.enter

  <button type="submit" (keyup.enter)="search(...)">Search</button>

Solution 3

In case anyone is wondering what input value

<input (keydown.enter)="search($event.target.value)" />

Solution 4

In addition to other answers which helped me, you can also add to surrounding div. In my case this was for sign on with user Name/Password fields.

<div (keyup.enter)="login()" class="container-fluid">

Solution 5

Try to use keyup.enter but make sure to use it inside your input tag

<input
  matInput
  placeholder="enter key word"
  [(ngModel)]="keyword"
  (keyup.enter)="addToKeywords()"
/>

I have added the whole HTML from my component as your suggested fixed doesn't submit when I click 'Enter'

[Optimist Rohit]

This is simple and works like a charm.

Or you could just use (ngSubmit)="onSubmit()"

Its sufficient at least in ionic project to decorate button with window:keypress event. Thanks Kamil, saved me having to write a @HostListener.. very succinct solution :-)

[Kieran Ryan]

Update: I spoke too soon.. of course window:keypress is too broad.. only interested in "return" key so maybe best to use @HostListener afterall :-)

event.keyCode is marked as deprecated. use event.key === 'Enter' instead of the first example

In case you are NOT using a FORM - here is solution stackoverflow.com/a/71092233/1461862 - it works for dialogs
