Package Exports

semantic-ui-react-labeledinput

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (semantic-ui-react-labeledinput) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Example usage

import React from 'react';
import LabeledInput from 'semantic-ui-react-labeledinput';

class LabeledInputExample extends React.Component {

    constructor(props) {
        super(props);
        this.state = {
            value: ""
        };
    }
    
    changeValue = (newValue) => {
        this.setState({ value: newValue });
    }
   
    render() => {(
        <LabeledInput inputId="address" label="Address" value={this.state.value} onValueChange={this.changeValue} />
    )};
}

LabeledInput with box presentation (default presentation mode)

<LabeledInput inputId="address" label="Address" presentation="box" value={this.state.value} onValueChange={this.changeValue} />

LabeledInput with line presentation

<LabeledInput inputId="address" label="Address" presentation="line" value={this.state.value} onValueChange={this.changeValue} />

LabeledInput with predefined validations

<LabeledInput errorText="value must be an integer" inputId="input1" label="Age" validation="integer" value={this.state.value} onValueChange={this.changeValue} />             
<LabeledInput errorText="Invalid e-mail address" inputId="input2" label="E-mail address" validation="emailAddress" value={this.state.value} onValueChange={this.changeValue} />

LabeledInput with regular expression validation

const regExp = /^\d{3,4}$/;
<LabeledInput inputId="input1" label="CVC" validation={regExp} value={this.state.value} onValueChange={this.changeValue} />

LabeledInput with validation function

const isEvenNumber = (valueStr) => {
    const value = parseInt(valueStr, 10);
    return value % 2 === 0;
}

<LabeledInput inputId="input1" label="Enter even number" validation={isEvenNumber} value={this.state.value} onValueChange={this.changeValue} />

LabeledInput with list of allowed values validation (case sensitive)

const allowedValues = ['value1', 'value2', 'value3'];
<LabeledInput inputId="input1" label="Enter value" validation={allowedValues} value={this.state.value} onValueChange={this.changeValue} />

More examples can be found in demo/demo.tsx file
