Forms

About

The form component adds styling to standard html form elements (textboxes, textareas, selects, checkboxes, radio buttons, submit buttons) giving them a native like look and feel on various platforms.

Starting from 4.8.0 the form elements can be used separately using their own attributes to initialize.

<mobiscroll.Form />

The mobiscroll.Form by default renders a form element. If the first child of the mobiscroll.Form is a form component, then it will use that, and won't render an additional form.
Above the Forms options, it supports the following props:

<mobiscroll.Form theme="mobiscroll-dark" action="/login" method='POST'>
    <p>This is a Login demo with Mobiscroll Form</p>
    <mobiscroll.Input type="email" value={this.state.email} onChange={this.emailChanged}>
        Email
    </mobiscroll.Input>
    <mobiscroll.Input type="password" value={this.state.password} onChange={this.passwordChanged}>
        Password
    </mobiscroll.Input>
    <button type="button" onClick={this.submit}>Sign In</button>
</mobiscroll.Form>

Options

Events

<mobiscroll.Forms
    onInit={function (event, inst) {
    }}
/>

Methods

mobiscrollInstance.option({
    display: 'bottom',
    lang: 'de'
});

mobiscrollInstance.refresh();

mobiscrollInstance.tap('#element', function () { alert("It's a tap!"); });

Localization

Validation

The Mobiscroll Forms component does not have built in validation mechanism, but provides error state stylings.
Use the valid and errorMessage props, to marke a field invalid and show the error message wanted.

<mobiscroll.Input valid={false} errorMessage="Invalid input">
    Username
</mobiscroll.Input>
    

Examples of how to implement simple validation logic on form fields can be found here

Sample validation using the formsy-react package.

The formsy-react third party package is a form input builder and validator for React.

The following is an example of how to use the mobiscroll react components with formsy:

1. Step: Building a formsy element

First we need to import the withFormsy higher order component from the formsy-react package. Then we need Mobiscroll Form Components. In this example we will use a Mobiscroll Input, but the othere form components (dropdown, textarea) work the same way.

import { withFormsy } from 'formsy-react';
import mobiscroll from './lib/mobiscroll.react';

We need a way to pass the formsy validation error and error state to the mobiscroll input. We are going to create a component for that:

class MidInput extends React.Component {
  constructor(props) {
    super(props);
    this.changeValue = this.changeValue.bind(this);
  }

  changeValue(event) {
    // setValue() will set the value of the component, which in
    // turn will validate it and the rest of the form
    // Important: Don't skip this step. This pattern is required
    // for Formsy to work.
    this.props.setValue(event.currentTarget.value);
  }

  render() {
    // An error message is returned only if the component is invalid
    const errorMessage = this.props.getErrorMessage();

    return (
      <mobiscroll.Input onChange={this.changeValue} value={this.props.getValue() || ''} errorMessage={errorMessage} valid={!errorMessage} type={this.props.type}>
        {this.props.children}
      </mobiscroll.Input>
    );
  }
}
    
export default withFormsy(MidInput);

2. Step: Using the input

We can now use the component the withFormsy higher order component returned. Let's import it and make a form:

import MyInput from './myinput';
import mobiscroll from './lib/mobiscroll.react';

class App extends Component {
  render() {
    return (
        <Formsy onValidSubmit={this.submit} onValid={this.onValid} onInvalid={this.onInvalid}>
            <mobiscroll.Form renderForm={false}>
                <MyInput
                    name="email"
                    validations="isEmail"
                    validationError="This is not a valid email"
                    required>My Formsy Email</MyInput>

                <MyInput
                    name="password"
                    type="password"
                    validations="minLength:6"
                    validationError="Invalid"
                    validationErrors={{
                        minLength: 'Has to be min 6 chars'
                    }}
                    required>My Formsy Password</MyInput>
            </mobiscroll.Form>
        </Formsy>
    );
  }
}

export default App;

Customizing the appearance

While the provided pre-built themes are enough in many use cases, most of the times on top of adapting to a specific platform, you'd also like to match a brand or color scheme. Mobiscroll provides various ways to achieve this:

• Create custom themes using the theme builder - the custom themes can be also built using out theme builder, on a graphical user interface, without any coding, or the need for Sass support in your project.
• Create custom themes using Sass - use this, if you need multiple themes with different color variatons, in case you have pages with different colors, or you'd like to users to customize the colors of your app.
• Override the Sass color variables - the straightforward way to change the colors in one place throughout the application.

Override the Sass Color Variables

A convenient way to customize the colors of the Mobiscroll components is to override the Sass color variables.

Let's say your branding uses a nice red accent color, and you'd like that color to appear on the Mobiscroll components as well, while still using platform specific themes (e.g. ios on iOS devices, material on Android devices, and mobiscroll on desktop). You can override the accent color for every theme:

$mbsc-ios-accent: #e61d2a;
$mbsc-material-accent: #e61d2a;
$mbsc-mobiscroll-accent: #e61d2a;

@import "~@mobiscroll/React/dist/css/mobiscroll.react.scss"

You can also customize the colors on many levels:

1. Theme specific variables (ex. $mbsc-material-background, $mbsc-ios-dark-text) are applied to all components in a theme. Complete list of variables here.
2. Component specific global variables (ex. $mbsc-card-background-light, $mbsc-listview-text-dark) are applied to all themes for a specific component.
3. Component and theme specific variables (ex. $mbsc-ios-dark-form-background, $mbsc-material-input-text) are applied to a specific theme and a specific component.

Hereinafter you will see all the variables that are specific to the Form component or affect its look:

Global variables

These variables are applied to all base themes: iOS, material, windows and mobiscroll.
They all come in pairs. One for the light and one for the dark variant in each theme.

Variables specific to individual form components can be found on the links below:

• Input, Password, Textarea
• Dropdown
• Checkbox
• Switch
• Radio buttons
• Button
• Slider
• Progress
• Segmented
• Stepper
• Rating
• FormGroup
• Alerts

If you really want to get sophisticated or if a color doesn't look good on a specific theme and you want to overwrite it, you can fine tune all of the above variables individually for each theme. Below are the complete list of variables broken down to themes:

iOS theme

iOS Dark theme

Windows theme

Windows Dark theme

Material theme

Material Dark theme

Mobiscroll theme

Mobiscroll Dark theme

Groups

For styling the groups inside the form element you can use the mbsc-form-group, mbsc-form-group-title and mbsc-form-group-inset classes.

<mobiscroll.FormGroup>
    <mobiscroll.FormGroupTitle>Phone</mobiscroll.FormGroupTitle>
    <mobiscroll.FormGroupContent>
        <mobiscroll.Input id="email" type="email" name="Email" placeholder="Email" />
	<mobiscroll.Input name="password" placeholder="Password" passwordToggle={true} icon="none" iconAlign="right" />
    </mobiscroll.FormGroupContent>
</mobiscroll.FormGroup>
        

<mobiscroll.FormGroup inset> 
    <mobiscroll.FormGroupTitle>Phone</mobiscroll.FormGroupTitle>
    <mobiscroll.FormGroupContent>
        <mobiscroll.Input id="email" type="email" name="Email" placeholder="Email" />
	<mobiscroll.Input name="password" placeholder="Password" passwordToggle={true} icon="none" iconAlign="right" />
    </mobiscroll.FormGroupContent>
</mobiscroll.FormGroup>

<mobiscroll.FormGroup collapsible open>
    <mobiscroll.FormGroupTitle>Phone</mobiscroll.FormGroupTitle>
    <mobiscroll.FormGroupContent>
        <mobiscroll.Input id="email" type="email" name="Email" placeholder="Email" />
	<mobiscroll.Input name="password" placeholder="Password" passwordToggle={true} icon="none" iconAlign="right" />
    </mobiscroll.FormGroupContent>
</mobiscroll.FormGroup>
