angular2-elastic_flowaccount v1.0.3

Angular2-Elastic

Automatically grows and shrinks textareas based on their content. Supports both regular Angular 2 <textarea> and Ionic 2 <ion-textarea> controls.

See the demo here.

Installation

npm install angular2-elastic

Quick Start

1. Import the ElasticModule.
2. Add the directive fz-elastic to your textarea or ion-textarea.
3. Watch as your textareas automatically grow and shrink depending on their content.

Usage

Angular 2

1. Import the ElasticModule:

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }   from '@angular/forms';
import { ElasticModule } from 'angular2-elastic';

import { AppComponent }  from './app.component';

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    ElasticModule
  ],
  declarations: [
    AppComponent
  ],
  bootstrap: [ AppComponent ]
})
export class AppModule {}

2. Use the directive in your component HTML:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  template: `<textarea fz-elastic></textarea>`
})
export class AppComponent {};

That's it! Your textarea will now grow and shrink as you type.

The textarea will also respond to changes from any one or two way bindings that are setup, e.g. with [(ngModel)].

Ionic 2

1. Import the module as above.
2. Use the directive on an ion-textarea instead:

<ion-textarea fz-elastic></ion-textarea>
