    Gets or sets the mask for the text field. Possible tokens in the mask:

    • 0 - Digit

    • ? - ASCII Letter or space
    • & - Non-whitepsace character
    • C - Any charcter
    • A - ASCII Letter or digit
    • a - ASCII Letter or digit or space

    If you want to escape any token character you can use \ (for example \9)

Usage

You need to add xmlns:mtf="nativescript-masked-text-field" to your page tag, and then simply use <mtf:MaskedTextField/> in order to add the widget to your page.

<!-- test-page.xml -->
<Page xmlns="http://schemas.nativescript.org/tns.xsd" xmlns:mtf="nativescript-masked-text-field">
    <StackLayout>
        <mtf:MaskedTextField text="{{ value }}" mask="(999) 999-9999" keyboardType="phone"/>
    </StackLayout>
</Page>

Usage in Angular

In order to be able to use the widget you just need to import MaskedTextFieldModule in NgModule:

import { MaskedTextFieldModule } from "nativescript-masked-text-field/angular";
// ......
@NgModule({
    // ......
    imports: [
        // ......
        MaskedTextFieldModule,
        // ......
    ],
    // ......
})
Example Usage
// main.ts
import { NgModule } from "@angular/core";
import { NativeScriptModule } from "nativescript-angular/nativescript.module";
import { platformNativeScriptDynamic } from "nativescript-angular/platform";
import { MaskedTextFieldModule } from "nativescript-masked-text-field/angular";
import { AppComponent } from "./app.component";

@NgModule({
    declarations: [ AppComponent ],
    bootstrap:    [ AppComponent ],
    imports:      [
        NativeScriptModule,
        MaskedTextFieldModule,
    ],
})
class AppComponentModule {
}

platformNativeScriptDynamic().bootstrapModule(AppComponentModule);
<!-- app.component.html -->
<StackLayout>
    <MaskedTextField class="input input-border" mask="(999) 999-9999" [(ngModel)]="value" keyboardType="phone"></MaskedTextField>
</StackLayout>
// app.component.ts
import { Component } from "@angular/core";

@Component({
    selector: "my-app",
    templateUrl:"app.component.html",
})
export class AppComponent {
    public value = "";
}

Demos

This repository includes both Angular and plain NativeScript demos. In order to run those execute the following in your shell:

$ git clone https://github.com/peterstaev/nativescript-masked-text-field
$ cd nativescript-masked-text-field
$ npm install
$ npm run demo-ios

This will run the plain NativeScript demo project on iOS. If you want to run it on Android simply use the -android instead of the -ios sufix.

If you want to run the Angular demo simply use the demo-ng- prefix instead of demo-.
