This issue applied the standard implementation without additional customisations.
The is no value on submit of the form and onChange does not fire with the current value.
<Form onSubmit={handleSubmit(this.onSubmit)}>
<Form.Group>
<Field
component={SemanticDatepicker}
name="working"
dateFormat="DD/MM/YYYY"
label="Date of birth"
placeholder="select your DOB"
size="small"
onChange={(e, value) => {
console.log(e, value);
}}
/>
</Form.Group>
<Form.Field
control={Button}
color="purple"
className="submit-btn"
type="submit"
width={6}
>
Save
</Form.Field>
</Form>
A minimal version can be found here https://github.com/chrishj59/datepickerIssue
I could capture the onChange value by creating a custom component which wrapped the <SemanticDatepicker />. I also added mapStateToProps to log the redux-form values. You can consider this as a starting point and work on this.
//SongList.js
state = {
date: "",
};
render(){
const DatePick = () => {
return (
<SemanticDatepicker
onChange={this.datePickerOnChange}
format="YYYY-MM-DD"
/>
);
};
return (
<Form onSubmit={handleSubmit(this.onSubmit)}>
<Form.Group>
<Field
component={DatePick}
name="working"
dateFormat="DD/MM/YYYY"
label="Date of birth"
placeholder="select your DOB"
size="small"
/>
</Form.Group>
<Form.Field
control={Button}
color="purple"
className="submit-btn"
type="submit"
width={6}
>
Save
</Form.Field>
</Form>
);
}
//App.js
import { connect } from "react-redux";
const App = (props) => {
console.log(props.form);
return (
<div>
{" "}
<SongList />
</div>
);
};
const mapStateToProps = (state) => ({
form: state.form,
});
export default connect(mapStateToProps)(App);
I managed to resolve using semantic-ui-redux-form-fields to wrap the Semantic UI component. This now gives the correct format and value appearing in the validate function and formProps.
import React from "react";
imp ort { fieldEnhance } from "semantic-ui-redux-form-fields";
import { compose } from "redux";
import SemanticDatepicker from "react-semantic-ui-datepickers";
import "react-semantic-ui-datepickers/dist/react-semantic-ui-datepickers.css";
const DatePickerPure = (props) => {
const { currentValue, input, ...rest } = props;
const defaultProps = {
format: "DD/MMM/YYYY",
onChange: (event, data) => input.onChange(data.value),
value: currentValue,
...rest,
};
return <SemanticDatepicker {...props} {...defaultProps} />;
};
export default compose(fieldEnhance)(DatePickerPure);

I was trying to take example from react but seem it doesn't work as I expected.
I am trying to open a modal when user click the button in parent component, but function to open modal is located in the child component.
Parent component just where i try to invoke a modal:
<label class="text-white m-5 p-1">
<input type="checkbox" checked={false} onChange={handleCheck} />
I have read and agree to the <button onClick={}>Privacy</button>
<Portal>
<TermsModal />
</Portal>
</label>
How to do that?
If you want the Modal component to control the state, instead of it being passed with props you can use this pattern:
const { Modal, openModal } = createModal();
return (
<>
<button type="button" onClick={openModal}>
open modal
</button>
<Modal />
</>
);
It may be weird at first, but it's really fun and powerful :)
https://playground.solidjs.com/anonymous/d3a74069-e3d4-4d3e-9fb2-bafc5d6f5bf5
Create a signal inside parent component and pass it to the child component. Bind the visibility of the modal window to the signal's value:
import { Component, createSignal, Show } from 'solid-js';
import { Portal, render } from 'solid-js/web';
const Modal: Component<{ show: boolean }> = (props) => {
return (
<Show when={props.show}>
<div>Modal Window</div>
</Show>
);
};
const App = () => {
const [show, setShow] = createSignal(false);
const toggleShow = () => setShow(prev => !prev);
return (
<div>
<div>Show: {show() ? 'true': 'false'} <button onClick={toggleShow}>Toggle Show</button></div>
<Portal><Modal show={show()} /></Portal>
</div>
)
};
render(() => <App />, document.body);
https://playground.solidjs.com/anonymous/adf9ba7a-3e1b-4ce9-92b2-e78ff3fa55ec
You can further improve your component by creating a close handler and passing it to the child component. Now, modal window can show a close button.
Also you can add an event handler to the document in order to close the window whenever Escape key is pressed:
import { Component, createSignal, onCleanup, onMount, Show } from 'solid-js';
import { Portal, render } from 'solid-js/web';
const Modal: Component<{ show: boolean, close: () => void }> = (props) => {
const handleKeydown = (event) => {
if (event.key === 'Escape') {
props.close();
}
};
onMount(() => {
document.addEventListener('keydown', handleKeydown);
});
onCleanup(() => {
document.removeEventListener('keydown', handleKeydown);
});
return (
<Show when={props.show}>
<div>Modal Window <button onclick={props.close}>close</button></div>
</Show>
);
};
const App = () => {
const [show, setShow] = createSignal(false);
const close = () => setShow(false);
const toggleShow = () => setShow(prev => !prev);
return (
<div>
<div>Show: {show()} <button onClick={toggleShow}>Toggle Show</button></div>
<Portal><Modal show={show()} close={close} /></Portal>
</div>
)
};
render(() => <App />, document.body);
https://playground.solidjs.com/anonymous/0ae98cf1-19d6-487f-80dc-72d3c2e554dc
You can use a state in the parent component to keep track of whether the modal should be open or closed, and pass a function as a prop to the child component that updates that state:
const [isModalOpen, setIsModalOpen] = React.useState(false);
const handleButtonClick = () => {
setIsModalOpen(true);
};
return (
<div>
<label className="text-white m-5 p-1">
<input type="checkbox" checked={false} onChange={handleCheck} />
I have read and agree to the <button onClick={handleButtonClick}>Privacy</button>
<Portal>
<TermsModal isOpen={isModalOpen} onClose={() => setIsModalOpen(false)} />
</Portal>
</label>
</div>
);
// Child component
const TermsModal = ({ isOpen, onClose }) => {
if (!isOpen) {
return null;
}
return (
<div className="modal">
{/* Modal content */}
<button onClick={onClose}>Close</button>
</div>
);
};
I am trying to implement tailwindcss styles into Formik to style forms. But the styles declared through className are not being applied?
I think Formik is using classname to define input type and tailwind uses the same method to declare styles?
my form page:
import React from "react";
import * as yup from "yup"
import { Formik, Form } from 'formik'
import { MyTextInput } from "../components/FormParts";
let mainFormSchema = yup.object().shape({
name: yup.string().trim().required()
})
const tryMainForm = () => {
const initValues = {
name: ''
}
return (
<div>
<h1>Any place in your app!</h1>
<Formik
initialValues={initValues}
validationSchema={mainFormSchema}
onSubmit={(values, { setSubmitting }) => {
setTimeout(() => {
alert(JSON.stringify(values, null, 2));
setSubmitting(false);
}, 400);
}}
>
{({ isSubmitting }) => (
<Form>
<MyTextInput
label="name"
name="name"
type="text"
placeholder="name"
/>
<button type="submit" disabled={isSubmitting}>
Submit
</button>
</Form>
)}
</Formik>
</div>
)
}
export default tryMainForm
formpart component:
import { useField } from "formik";
export const MyTextInput = ({ label, ...props }) => {
const [field, meta] = useField(props)
return (
<>
<label htmlFor={props.id || props.name} className="block text-sm font-medium text-gray-700">{label}</label>
<input className="shadow-sm focus:ring-indigo-500 focus:border-indigo-500 block w-full sm:text-sm border-gray-300 rounded-md" {...field} {...props} />
{meta.touched && meta.error ? (
<div className="error">{meta.error}</div>
) : null}
</>
)
}
can you suggest a way to deal with this?
tailwind applies styles properly to label but doesn't with input?
I'm fairly new Ionic React and trying to create an App using Ionic framework. I have a use case where I would like to redirect to another page upon a button press and validation from a function.
Here is the component I am working with
import React, { useState } from 'react';
import {
IonContent,
IonHeader,
IonPage,
IonTitle,
IonToolbar,
IonInput,
IonButton,
IonRow,
IonCol,
useIonViewWillEnter,
useIonViewWillLeave,
IonLabel
} from '#ionic/react';
import './LogIn.css'
import MainMenu from "../MainMenu";
const LogIn: React.FC<{register?: boolean; onClose?: any}> = () => {
const [email, setEmail] = useState<string>();
const [password, setPassword] = useState<string>();
function handleLoginButtonPress() {
if (validateEmail() && password !== undefined && password.trim() !== "") {
// Network call here to check if a valid user
console.log("valid email")
return <MainMenu/>
}
}
function validateEmail () {
if (email !== undefined && email.trim() !== "") {
const regexp = /^(([^<>()[\]\\.,;:\s#"]+(\.[^<>()[\]\\.,;:\s#"]+)*)|(".+"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
return regexp.test(email);
}
return false;
}
useIonViewWillEnter(() => {
console.log("Entering LogIn");
});
useIonViewWillLeave(() => {
console.log("Exiting LogIn");
});
return (
<IonPage id="loginIonPage">
<IonHeader>
<IonToolbar color="primary" mode="md">
<IonTitle class="ion-text-center">Login or Register</IonTitle>
</IonToolbar>
</IonHeader>
<IonContent id="loginPage">
<div id="loginDialog">
<form>
<IonLabel>Email</IonLabel>
<IonRow>
<IonCol id="userName">
<IonInput
name="email"
value={email}
onIonChange={e => setEmail(e.detail.value!)}
clearInput
type="email"
placeholder="Email"
class="input"
padding-horizontal
clear-input="true"
required/>
</IonCol>
</IonRow>
<IonLabel>Password</IonLabel>
<IonRow>
<IonCol id="password">
<IonInput
clearInput
name="password"
value={password}
onIonChange={e => setPassword(e.detail.value!)}
type="password"
placeholder="Password"
class="input"
padding-horizontal
clear-input="true"
required/>
</IonCol>
</IonRow>
</form>
</div>
<div id="buttons">
<IonButton
onClick={handleLoginButtonPress}
type="submit"
strong={true}
expand="full"
style={{ margin: 20 }}>
Log in
</IonButton>
<IonButton
routerLink="/registerUser"
type="submit"
strong={true}
expand="full"
style={{ margin: 20 }}>
Register
</IonButton>
</div>
</IonContent>
</IonPage>
);
};
export default LogIn;
How can I redirect to another page from the function handleLoginButtonPress which is invoked upon clicking on Login button. I tried reading through ionic doc but that did not help as it redirects whenever there is button click or click on an IonElement like IonLabel.
Use react-router-dom hooks
https://reacttraining.com/react-router/web/api/Hooks/usehistory
import { useHistory } from "react-router-dom";
const ExampleComponent: React.FC = () => {
const history = useHistory();
const handleLoginButtonPress = () => {
history.push("/main");
};
return <IonButton onClick={handleLoginButtonPress}>Log in</IonButton>;
};
export default ExampleComponent;
Thanks, #MUHAMMAD ILYAS and it would have worked for me. But I managed to leverage the react state as below, I have added as an answer as I could not format the code there,
const ValidateUser : React.FC = () => {
const [login, setLogin] = useState(false);
function isUserLoggedIn() {
return login;
}
return(
<IonReactRouter>
<IonRouterOutlet>
<Route path="/" render={() => isUserLoggedIn()
? <MainMenu/>
: <LogIn setUserLoggedIn={() => {setLogin(true)}}/>} exact={true}/>
</IonRouterOutlet>
</IonReactRouter>
);
};
const LogIn: React.FC<{setUserLoggedIn?: any}> = ({setUserLoggedIn}) => {
.
.
function onLoginButtonPress() {
setUserLoggedIn();
}
}
Thanks
my original code was like this:
handleClick() {
var name = this.refs.name.value;
var description = this.refs.description.value
}
render () {
return (
<React.Fragment>
<input ref='name' placeholder='Enter the name of the item' />
<input ref='description' placeholder='Enter a description' />
<Button onClick={this.handleClick.bind(this)}>Submit</Button>
</React.Fragment>
);}
name and description can get the inputs correctly.
But when I use <TextField>:
<TextField ref='name' placeholder='Enter the name of the item' />
it shows that the value passed is null, it seems that ref does not work.
Can anyone help me solve this problem?
String refs are deprecated and material-ui does not support using them. I recommend reading: https://reactjs.org/docs/refs-and-the-dom.html
Also to get a ref to the <input /> element you should use the inputRef prop. Read about it here.
If your React is up to date you should use createRef or the useRef hook. Below are some examples
// Using the useRef() hook. Only possible when you're using a function component.
const App = () => {
const textRef = useRef();
const showRefContent = () => {
console.log(textRef.current.value);
};
return (
<div className="App">
<TextField inputRef={textRef} />
<button onClick={showRefContent}>Click</button>
</div>
);
}
// Using createRef(). Use this when working in a React.Component
class App extends React.Component {
constructor(props) {
super(props);
this.textRef = createRef();
}
showRefContent = () => {
console.log(this.textRef.current.value);
};
render() {
return (
<div className="App">
<TextField inputRef={this.textRef} />
<button onClick={this.showRefContent}>Click</button>
</div>
);
}
}
Or if your React isn't up to date you can store it in a local variable, but this isn't the preferred way.
class App extends React.Component {
showRefContent = () => {
console.log(this.textRef.value);
};
render() {
return (
<div className="App">
<TextField inputRef={element => (this.textRef = element)} />
<button onClick={this.showRefContent}>Click</button>
</div>
);
}
}
Also, you might want to consider using state instead of having to create refs for all fields and then retrieving the values from the dom.
I have to implement a form with a bit less than 30 different fields.
So I decided to split them in 2 differents container component with two tabs to navigate between them.
I use redux-form to handle the data binding.
For on component I can get the value from handleSubimit of one component. But the final validation must be in the last tab only. From here I only have access to the value of the second tab. Like the data from the store where wipe out.
How can I access the store where my previous data should be ?
TabNavigationBar.js
import React from 'react';
import TabNavigationItem from './TabNavigationItem';
const TabNavigationBar = ({ onTabChange, activeTab }) => {
const tabList = [
{ hasIcon: 'fas fa-user-circle', hastext: 'Information Utilisateur' },
{ hasIcon: 'fas fa-file-alt', hastext: 'Informations contrat' }
];
const clickOnTab = tabNumer => {
onTabChange(tabNumer);
};
return (
<div className="columns">
<div className="column is-offset-one-quarter-desktop is-offset-one-thirds-tablet is-half-desktop is-one-thirds-tablet">
<div className="tabs is-toggle is-fullwidth">
<ul>
{tabList.map((tab, i) => (
<TabNavigationItem
key={i}
tabSelected={() => clickOnTab(i)}
hasClass={activeTab === i ? 'is-active' : ''}
hasIcon={tab.hasIcon}
hasText={tab.hastext}
/>
))}
</ul>
</div>
</div>
</div>
);
};
export default TabNavigationBar;
UserForm.js
import React from 'react';
import { reduxForm } from 'redux-form';
import CiviliteRadioButton from './CiviliteRadioButton';
import NameInputs from './NameInputs';
import AddressInputs from './AddressInputs';
import MailAndDOB from './MailAndDOB';
import TelephoneInputs from './TelephoneInputs';
let UserForm = ({ handleSubmit }) => {
return (
<div>
<CiviliteRadioButton />
<NameInputs />
<AddressInputs />
<MailAndDOB />
<TelephoneInputs />
</div>
);
};
UserForm = reduxForm({
form: 'form1',
initialValues: {
user: {
adresse: {
country: 'France'
},
civilite: 'Madame'
}
}
})(UserForm);
export default UserForm;
ContractForm.js
import React from 'react';
import { reduxForm } from 'redux-form';
import InputItem from '../InputItem';
import ContratInputsList from './contratInputList';
let ContratForm = ({ handleSubmit }) => {
const submit = values => {
console.log(values);
};
return (
<div>
<div className="columns is-multiline ">
{ContratInputsList.map((item, i) => {
return (
<div className="column is-half" key={i}>
<InputItem spec={item.spec} />
</div>
);
})}
</div>
<div className="columns">
<div className="column">
<div className="field is-grouped is-grouped-right">
<input
className="button is-primary"
onClick={handleSubmit(submit)}
type="submit"
value="Envoyer"
/>
</div>
</div>
</div>
</div>
);
};
ContratForm = reduxForm({
form: 'form2'
})(ContratForm);
export default ContratForm;
EDIT
When I click on my tabs, redux-form/DESTROY is called and erase form1's data.
Try setting destroyOnUnmount flag to false in reduxForm(options).
