Install the package by command:

    npm install ngx-currency --save

Import the module

import { NgxCurrencyModule } from "ngx-currency";

@NgModule({
    imports: [
        ...
        NgxCurrencyModule
    ],
    declarations: [...],
    providers: [...]
})
export class AppModule {}

<input currencyMask formControlName="value" />

• ngModel An attribute of type number. If is displayed '$ 25.63', the attribute will be '25.63'.

You can set options...

<!-- example for pt-BR money -->
<input currencyMask formControlName="value" [options]="{ prefix: 'R$ ', thousands: '.', decimal: ',' }"/>

Available options:

• align - Text alignment in input. (default: right)
• allowNegative - If true can input negative values. (default: true)
• decimal - Separator of decimals (default: '.')
• precision - Number of decimal places (default: 2)
• prefix - Money prefix (default: '$ ')
• suffix - Money suffix (default: '')
• thousands - Separator of thousands (default: ',')
• nullable - when true, the value of the clean field will be null, when false the value will be 0
• min - The minimum value (default: undefined)
• max - The maximum value (default: undefined)
• inputMode - Determines how to handle numbers as the user types them (default: FINANCIAL)

Input Modes:

• FINANCIAL - Numbers start at the highest precision decimal. Typing a number shifts numbers left. The decimal character is ignored. Most cash registers work this way. For example:
  • Typing '12' results in '0.12'
  • Typing '1234' results in '12.34'
  • Typing '1.234' results in '12.34'
• NATURAL - Numbers start to the left of the decimal. Typing a number to the left of the decimal shifts numbers left; typing to the right of the decimal replaces the next number. Most text inputs and spreadsheets work this way. For example:
  • Typing '1234' results in '1234'
  • Typing '1.234' results in '1.23'
  • Typing '12.34' results in '12.34'
  • Typing '123.4' results in '123.40'

You can also set options globally...

import { CurrencyMaskInputMode, NgxCurrencyModule } from "ngx-currency";

export const customCurrencyMaskConfig = {
    align: "right",
    allowNegative: true,
    allowZero: true,
    decimal: ",",
    precision: 2,
    prefix: "R$ ",
    suffix: "",
    thousands: ".",
    nullable: true,
    min: null,
    max: null,
    inputMode: CurrencyMaskInputMode.FINANCIAL
};

@NgModule({
    imports: [
        ...
        NgxCurrencyModule.forRoot(customCurrencyMaskConfig)
    ],
    declarations: [...],
    providers: [...],
    bootstrap: [AppComponent]
})
export class AppModule {}

Input not working on mobile keyboard

<!-- Change the type to 'tel' -->
    <input currencyMask type="tel" formControlName="value" />

Input focus get hide by the mobile keyboard

on HTML

<!-- Change the type to 'tel' -->
    <input currencyMask type="tel" formControlName="value" [id]="'yourInputId' + index" (focus)="scrollTo(index)" />

on .ts

import { Content } from 'ionic-angular';

export class...

    @ViewChild(Content) content: Content;
  
    scrollTo(index) {
        let yOffset = document.getElementById('yourInputId' + index).offsetTop;
        this.content.scrollTo(0, yOffset + 20);
    }

• Install Node.js and NPM
• Install local dev dependencies: npm install while current directory is this repo

Run npm start or npm run demo to start a development server on port 8000 with auto reload + tests.

• Run npm test to run tests once
• Run npm run test:watch to continually run tests in headless mode
• Run npm run test:watch-browser to continually run tests in the Chrome browser

When running in the Chrome browser, you can set code breakpoints to debug tests using these instructions:

• From the main Karma browser page, click the Debug button to open the debug window
• Press ctrl + shift + i to open Chrome developer tools
• Press ctrl + p to search for a file to debug
• Enter a file name like input.handler.ts and click the file
• Within the file, click on a row number to set a breakpoint
• Refresh the browser window to re-run tests and stop on the breakpoint
