on submit form, couldn't get react-select values - reactjs

onSubmit(values) {
console.log("i m clicked", values); /// i didn't get form values
here.
}
renderMacros() {
const { handleSubmit } = this.props;
const macrosData = this.props.macros.macros;
const categoryMacrosData = this.props.categoryMacros.category;
console.log("categoryMacrosData", categoryMacrosData);
const { open } = this.state;
if (macrosData) {
return (
<div>
<div className="form-block-5 w-form">
<form
id="macros-form"
name="macros-form"
onSubmit={handleSubmit(this.onSubmit)}
>
<div className="row">
<div className="col-sm-12">
<label>Type</label>
<Field // this works fine
name="category"
options={MACRO_TYPE_CATEGORIES}
placeholder="Type"
component={SelectInput}
set_default="true"
/>
</div>
<div className="col-sm-12">
<Field // this works fine
name="name"
placeholder="Name Ex. Follow-up template"
component={renderField}
type="text"
className="text-fields w-input"
id="macros_name"
/>
</div>
<div className="col-sm-12">
<Field // here is the problem
type="text"
name="categoryId"
options={categoryMacrosData}
placeholder="Search or add category "
component={AsyncMulti}
handleSelect={this.handleSelectChange}
/>
</div>
</div>
<button>Create Macro</button>
</form>
</div>
</div>
);
}
}
Bottom line is if i use Creatable component of react-select library, i
couldn't get selected values.
My component file: components/Multi.js
import React from "react";
import CreatableSelect from "react-select/lib/Creatable";
const MultiSelect = props => {
const { options, handleSelect } = props;
return <CreatableSelect isMulti onChange={handleSelect} options=
{options} />;
};
export default MultiSelect;
I am using react-select for select options in redux form. After
submitting form, I am unable to get form submitted values.
I am using react-select library https://react-select.com/creatable with redux form.

Given a props name in <Select> like
<Select
name = {"inputName"} // <- if you submit the form you will get vale like {"inputName":test111}
options = {[{ value: 'test111', label: 'Chocolate' }]}
/>

You are not binding handleSubmit properly as well not using refs since you are not getting the values.
I suggest you to try with the binding code in your <form> tag:
<form
id="macros-form"
name="macros-form"
onSubmit={this.handleSubmit.bind(this)}
>
Also pass refs in your field tag to get the value:
<Field
name="categoryId"
options={categoryMacrosData}
placeholder="Search or add category "
component={Multi}
handleSelect={this.handleSelectChange}
ref="categoryId"
/>
Instead of writing onSubmit function:
onSubmit(values) {
console.log("i m clicked", values); /// i didn't get form values
here.
}
Replace it with this function code:
handleSubmit(event) {
if (this.refs.categoryId !== '') {
event.preventDefault();
console.log('categoryId: ', this.refs.categoryId.value)
}
}
Hope it helps you!

REACT: conditionally rendering a alert if field left blank

I have the following React form:
import React from 'react';
export default class ChatBar extends React.Component {
mySubmitHandler = event => {
event.preventDefault();
/* you can access the value as below */
const inputName = this.refInputName.value;
const inputEmail = this.refInputEmail.value;
const inputMessage = this.refInputMessage.value;
// const inputStamp = this.convertDate(new Date())
const message = {name: inputName, email: inputEmail, content: inputMessage, stamp: inputStamp}
this.props.addMessage(message)
this.refInputMessage.value = ""
}
render() {
return (
<div>
<h4>Leave a Comment</h4>
<form onSubmit={this.mySubmitHandler}>
<label>Your name
<input
type="text"
name="name"
ref={(node) => (this.refInputName = node)}
/>
</label>
<label>Your email
<input
type="text"
name="email"
ref={(node) => (this.refInputEmail = node)}
/>
</label>
<label>Your message
<textarea ref={(node) => (this.refInputMessage = node)} />
</label>
<br />
<input className="submit-button" type="submit" value="Submit comment" />
</form>
</div>
)
};
};
I need to create a way so that when an input is left black and either submitted or hovered over, it creates a "tool tip" alerting the user the field has been left blank (see attached image). I have tread fooling around with onHover, onClick and onSubmit handlers to render some state of tool tip being "true" and conditionally render the toolTip div however it does not seem to be working and I am rather lost, now starting from scratch again.
Any help is greatly appreciated =)
I recommend react-valida-hook, it's really simple to use, you can add personalized messages, the only thing you need to do is pass the error.
Example:
const displayError = (errs) => {
if (errs.indexOf('required') !== -1) {
return '*Super important required field';
}
if (errs.indexOf('minLength') !== -1) {
return '*Too short man!';
}
if (errs.indexOf('isEmail') !== -1) {
return '*That looks wrong';
}
return '';
};
<div className="errors">
// I use a variable to show only errors wen form is submitted
{submitted && displayError(validation.errors.firstName)}
</div>
You can make two custom CSS class for visibility: hidden, ect.
Then render the toolTip div like such:
<div className="tool-tip" style={this.state.showTip ? visible : hidden}>testing </div>

ReactJS: Validation not working with Yup using Formik multistep form

I have a multi steps form in which i have used a Formik and Yup libraries.
But the validation that i am using of yup library is not working at all. In React debugger tool i am getting it's value as empty. So, whatever i write in the input field it validates with "Required" message as it's value is empty.
import { Formik, Form, Field, ErrorMessage } from 'formik';
import * as Yup from 'yup';
let accountInfoSchema = Yup.object().shape({
name: Yup.string()
.max(20, 'Too Long!')
.required('Name is Required'),
});
class AccountInfo extends Component {
handleChange = event => {
this.setState({
userAccountData: Object.assign(
{},
this.state.userAccountData,
{ [event.target.name]: event.target.value }
),
})
}
AccountInfoView = () => {
return (
<section className="form">
<React.Fragment>
<Formik
initialValues={{name:'' }}
validationSchema={accountInfoSchema}
render={() => {
return(
<Form onSubmit={this.handleSubmit}>
{this.Step1()}
{this.Step2()}
{this.Step3()}
<li className="stb_btn half">
<div className="custom_group">
{this.previousButton()}
</div>
</li>
<li className="stb_btn half">
<div className="custom_group">
{this.nextButton()}
</div>
</li>
</Form>
);
}}
/>
</React.Fragment>
</div>
</section>
)
}
Step1 = () => {
return(
<li>
<div className="custom_group">
<Field type="text" name="name" className="trans text_input" placeholder="Enter your name" value={this.state.userAccountData['name']} onChange={this.handleChange} />
<label className="label_two">Name</label>
<ErrorMessage name="name" />
</div>
</li>
)
}
render() {
return (
<div>{this.AccountInfoView()}</div>
)
}
}
please review the react console response for the value as empty.
The reason why it isn't validating is because you are passing to the Field this.state.userAccountData['name'] and onChange={this.handleChange}.
Formik already have a state to store all of the data from your form, you don't need to keep it in the components state.
When you add onChange={this.handleChange} to the field, you change the component's state, but don't change the Formik's state, this is why the validation isn't triggering.
I'm not sure why you are keeping the name in the state, but if you don't have any reason why these are unecessary.
// formik already handle the state for you inside `values`
handleChange = event => {
this.setState({
userAccountData: Object.assign(
{},
this.state.userAccountData,
{ [event.target.name]: event.target.value }
),
})
}
// Formik already handles the value and the onChange of the input
<Field type="text" name="name" className="trans text_input" placeholder="Enter your name" value={this.state.userAccountData['name']} onChange={this.handleChange} />
The only thing you need is to set the field's name prop, so it matches the validation.
// this is enough
<Field type="text" name="name" className="trans text_input" placeholder="Enter your name" />

Setting the default value of an input field after data is retrieved causes the content to overlap and the "onChange" event not to be triggered

I have an "edit category" component in my React application.
The ID is passed through the URL.
When the component is mounted, the action "fetchCategory" is called, which updates the props on the component with the current category.
I have a form which I want to be pre-populated, which I'm currently doing using the defaultValue on the input.
However, this isn't reflected on the state and the label for the text field overlaps the input field.
Any help would be greatly appreciated. I'll leave snippets of my code below which could help with understanding what I'm trying to do.
import React, { Component } from "react";
import { connect } from "react-redux";
import { fetchCategory } from "../../store/actions/categoryActions";
class AddOrEditCategory extends Component {
componentDidMount() {
this.props.fetchCategory(this.props.match.params.id);
if (this.props.match.params.id) {
this.setState({
_id: this.props.match.params.id
});
}
}
handleSubmit = e => {
e.preventDefault();
console.log(this.state);
};
handleChange = e => {
this.setState({
[e.target.id]: e.target.value
});
};
render() {
const addingNew = this.props.match.params.id === undefined;
return (
<div className="container">
<h4>{addingNew ? "Add category" : "Edit category"}</h4>
<form onSubmit={this.handleSubmit}>
<div className="input-field">
<input
type="text"
id="name"
defaultValue={this.props.category.name}
onChange={this.handleChange}
/>
<label htmlFor="name">Category name</label>
</div>
<div className="input-field">
<input
type="text"
id="urlKey"
onChange={this.handleChange}
defaultValue={this.props.category.urlKey}
/>
<label htmlFor="urlKey">URL Key</label>
</div>
<button className="btn">{addingNew ? "Add" : "Save"}</button>
</form>
</div>
);
}
}
const mapStateToProps = state => {
return {
category: state.categoryReducer.category
};
};
export default connect(
mapStateToProps,
{ fetchCategory }
)(AddOrEditCategory);
EDIT: Included whole component as requested
You need to replace the 'defaultValue' attribute with 'value' in the inputs.
You are using a controlled vs uncontrolled component. You dont need to use defaultValue.
You can set the initial values on the promise success for fetchCategory
componentDidMount() {
this.props.fetchCategory(this.props.match.params.id).then(response => {
// Set the initial state here
}
}
OR in
componentWillReceiveProps(nextProps) {
// Compare current props with next props to see if there is a change
// in category data received from action fetchCategory and set the initial state
}

Copy one Redux Form Value to Another

function mapStateToProps(state) {
let returnObject = {};
if (state && state.form) {
if (
state.form.someFormName &&
state.form.someFormName.values &&
state.form.someFormName.values.fieldNameX &&
state.form.someFormName.values.fieldNameX === "1"
) {
state.form.someFormName.values.fieldNameB =
state.form.someFormName.values.fieldNameA;
state.form.someFormName.values.fieldNameC =
state.form.someFormName.values.fieldNameD;
state.form.someFormName.values.fieldNameF =
state.form.someFormName.values.fieldNameE;
}
}
return returnObject;
}
This is Working Fine on selecting form field i am just copying redux form value to another field,How to do in Efficient Way?This is the Correct way to copy one form field into another ?
You can use formValueSelector to connect to your form value and than dispatch change action creator to update any field with your value.
Here is the example with textboxes(you can update it to use datePicker):
import {change, formValueSelector} from 'redux-form';
let FormName = (props) => {
const {dispatch, handleSubmit, firstValue} = props;
return <form onSubmit={handleSubmit}>
<div>
<label>First Value</label>
<Field
name='firstValue'
component='input'
type='text'
placeholder='First Value'
/>
</div>
<div>
<label>Copy value</label>
<div>
<Field
name='checkbox'
component='input'
type='checkbox'
value='checkboxValue'
onChange={(e) => {
if (e.target.checked) {
dispatch(change('formName', 'secondValue', firstValue));
}
}}
/>
</div>
</div>
<div>
<label>Second Value</label>
<Field name='secondValue' component='input' type='text'/>
</div>
<div>
<button type="submit">Submit</button>
</div>
</form>
};
const selector = formValueSelector('formName');
connect(
state => ({
firstValue: selector(state, 'firstValue'),
})
)(FormName);
This is not the Preferred method to change the state like this (You are mutating the state) Redux 2 Principle,Use this instead:
If you are using radio/checkbox, then onPress of that radio/checkbox you can copy all the field,then dispatch onChange action.
For Eg:
<Field
type="radio"
name="fieldNameX"
value="1"
onRadioPress={this.someMethod}
component={CustomRadioButton}
/>
someMethod() {
let formValues = Object.assign({}, this.props.formValues);
this.props.dispatch(
change("SomeForm", "fieldWantToCopy", value)
);
}

how to provide validations for react js form

How to provide validations for react js form.
I have taken form with two fields. if two fields are enabled then only need to enable save button.
import React from 'react'
import { Button, Checkbox, Form } from 'semantic-ui-react'
const FormExampleForm = () => (
<Form>
<Form.Field>
<label>First Name</label>
<input placeholder='First Name' />
</Form.Field>
<Form.Field>
<label>Last Name</label>
<input placeholder='Last Name' />
</Form.Field>
<Form.Field>
<Checkbox label='I agree to the Terms and Conditions' />
</Form.Field>
<Button type='submit'>Submit</Button>
</Form>
)
export default FormExampleForm
In redux forms 6.7 there's a simple property called pristine which can be used to do this. But if the user enters some value in at least one input field the submit button gets activated. To achieve that you may need to do something like this.
render() {
// const { handleSubmit } = this.props;
const {handleSubmit, pristine, reset, submitting} = this.props
return (
<form onSubmit={handleSubmit(this.onSubmit.bind(this))}>
<div>
<label>First Name</label>
<div>
<Field name="firstName" component="input" type="text" placeholder="First Name"/>
</div>
</div>
<button type="submit" className="btn btn-primary" disabled={pristine || submitting}>Submit</button>
</form>
);
}
}
But if you need to enable submit button, say when the user inputs values in 2 given fields or so, then this becomes complex. You need to do something like this. Here's my sample usecase. The form has 3 fields firstName, lastName and age. The submit button gets activated only if the user enters values for firstName and lastName input fields here. Please check out the following code.
import React, { Component } from 'react';
import { Field, reduxForm, formValueSelector } from 'redux-form';
import { connect } from 'react-redux';
class UserNew extends Component {
constructor(props) {
super(props);
this.isSubmitEnabled = this.isSubmitEnabled.bind(this);
}
onSubmit(values) {
console.log(values);
}
isSubmitEnabled() {
// Access field values here and validate them
const firstName = this.props.firstNameValue;
const lastName = this.props.lastNameValue;
if(firstName && lastName){
return true;
}
return false;
}
render() {
const { handleSubmit } = this.props;
const isEnabled = this.isSubmitEnabled();
return (
<form onSubmit={handleSubmit(this.onSubmit.bind(this))}>
<div>
<label>First Name</label>
<div>
<Field name="firstName" component="input" type="text" />
</div>
</div>
<div>
<label>Last Name</label>
<div>
<Field name="lastName" component="input" type="text" />
</div>
</div>
<div>
<label>Age</label>
<div>
<Field name="age" component="input" type="text" />
</div>
</div>
<button type="submit" className="btn btn-primary" disabled={!isEnabled}>Submit</button>
</form>
);
}
}
UserNew = reduxForm({
form: 'UserNewForm'
})(
UserNew
);
// Decorate with connect to read form values
const selector = formValueSelector('UserNewForm') // <-- same as form name
UserNew = connect(state => {
const firstNameValue = selector(state, 'firstName')
const lastNameValue = selector(state, 'lastName')
return {
firstNameValue,
lastNameValue,
}
})(UserNew)
export default UserNew;
To access field values you need to use formValueSelector in ReduxForms. For that you need to connect your form to redux store using connect helper.
Hope this helps. Happy coding !
Either you can use Redux-form as its not used in above code, so you can write custom JS validation code. For this you need to follow below
Initialise state in
contructor(){
this.state{
first_name: null,
last_name: null,
}
}
Change state of every input element onChange onChange={()=>this.setState({first_name: event.target.value})}
Now add onClick property to <Button onClick={this.handleSubmit} />
inside handleSubmit() you can get values through local state of component and add validation rules like
if(this.state.first_name =="") {
console.log("Enter first name")
}
