How to get input from ion-searchbar?

Question

It is super easy problem but I just can't seem to figure this out (And yes I have read the documentation).

I am trying to get the input user puts in the ion-searchbar (in Ionic v4) after they the press search and put in a const/let.

Mah HTML

<ion-searchbar showCancelButton="focus" class=""></ion-searchbar>

I don't know how I should write the TS for this.

Thanks in advance :{)

Answer 1

• Use (search) event to call your function. This event is fired when the user will click on the search button provided by the ion-searchbar.

• To get the value entered in the searchbar, use $event.target.value which gets the value field of the tag which in this case is <ion-searchbar>

  <ion-searchbar
      showCancelButton 
      searchIcon="search" 
      animated
      cancel-button-icon
      (ionCancel)="hideSearch()"
      (search)="yourSearchFunction($event.target.value)" 
      placeholder="Search Some Values">
  </ion-searchbar>
  

To listen to changes as user types in the search bar:

    <ion-searchbar
        ... 
        (ionInput)="yourInputChangeFunction($event.detail.value)">
    </ion-searchbar>

Note: On Ionic 6+, (ionInput) strangely emits value on $event.target.value although, their documentation mentions $event.detail

In your .html file:

<ion-searchbar
    [(ngModel)]="autocomplete.input"
    (ionInput)="updateSearchResults()"
    placeholder="Search for a place">
</ion-searchbar>

In your .ts file:

export class LoginPage{

  autocomplete: { input: string; }; 

  updateSearchResults() {
     console.log(this.autocomplete.input)    //search input will display
  }
}

Hope this works.

Html file.

<ion-toolbar>
    <ion-searchbar 
       debounce="1000" 
       (ionChange)="ionChange($event)">
    </ion-searchbar>
</ion-toolbar>

ts file

ionChange(event) {
    console.log(event.detail.value)
}

Answer 4

Get a reference to the searchbar using the @ViewChild directive:

View: <ion-searchbar #search></ion-searchbar>

Component: @ViewChild('search', {static: false}) search: IonSearchbar;

Thereafter, get the value of the ion-searchbar as follows:

const input = await this.search.getInputElement(); const searchValue = input.value;

Answer 5

Always Read Documentation of API, Plugins or anything which you are looking for. You will get data by using ionChange() or ionInput(). Use following code in HTML file

<ion-searchbar 
  showCancelButton="focus"  
  ionInput="getData()" 
  class="">
</ion-searchbar>

and in TypeScript.

public getData(){ 
   //ur logic here
}
