I create form, I have several TextField, DropDownMenu material-ui components included, question is how I can collect all data from all TextFields, DropDownMenus in one obj and sent it on server. For TextField it has TextField.getValue() Returns the value of the input. But I can`t understand how to use it.
var React = require('react'),
mui = require('material-ui'),
Paper = mui.Paper,
Toolbar = mui.Toolbar,
ToolbarGroup = mui.ToolbarGroup,
DropDownMenu = mui.DropDownMenu,
TextField = mui.TextField,
FlatButton = mui.FlatButton,
Snackbar = mui.Snackbar;

];
var menuItemsIcan = [

I want sent it on server in _handleClick method.
This question is related to
javascript
reactjs
material-design
material-ui
Here all solutions are based on Class Component, but i guess most of the people who learned React recently (like me), at this time using functional Component. So here is the solution based on functional component.
Using useRef hooks of ReactJs and inputRef property of TextField.
import React, { useRef, Component } from 'react'
import { TextField, Button } from '@material-ui/core'
import SendIcon from '@material-ui/icons/Send'
export default function MultilineTextFields() {
const valueRef = useRef('') //creating a refernce for TextField Component
const sendValue = () => {
return console.log(valueRef.current.value) //on clicking button accesing current value of TextField and outputing it to console
}
return (
<form noValidate autoComplete='off'>
<div>
<TextField
id='outlined-textarea'
label='Content'
placeholder='Write your thoughts'
multiline
variant='outlined'
rows={20}
inputRef={valueRef} //connecting inputRef property of TextField to the valueRef
/>
<Button
variant='contained'
color='primary'
size='small'
endIcon={<SendIcon />}
onClick={sendValue}
>
Send
</Button>
</div>
</form>
)
}
class Content extends React.Component {
render() {
return (
<TextField ref={(input) => this.input = input} />
);
}
_doSomethingWithData() {
let inputValue = this.input.getValue();
}
}
use the accepted answer / this was the answer to another (already deleted) question
@karopastal
add a ref
attribute to your <TextField />
component and call getValue() on it, like this:
Component:
<TextField ref="myField" />
Using getValue:
this.refs.myField.getValue()
I don't know about y'all but for my own lazy purposes I just got the text fields from 'document' by ID and set the values as parameters to my back-end JS function:
//index.js_x000D_
_x000D_
<TextField_x000D_
id="field1"_x000D_
..._x000D_
/>_x000D_
_x000D_
<TextField_x000D_
id="field2"_x000D_
..._x000D_
/>_x000D_
_x000D_
<Button_x000D_
..._x000D_
onClick={() => { printIt(document.getElementById('field1').value,_x000D_
document.getElementById('field2').value) _x000D_
}}>_x000D_
_x000D_
_x000D_
//printIt.js_x000D_
_x000D_
export function printIt(text1, text2) {_x000D_
console.log('on button clicked');_x000D_
alert(text1);_x000D_
alert(text2);_x000D_
};
_x000D_
It works just fine.
flson's code did not work for me. For those in the similar situation, here is my slightly different code:
<TextField ref='myTextField'/>
get its value using
this.refs.myTextField.input.value
Faced to this issue after a long time since question asked here. when checking material-ui code I found it's now accessible through inputRef
property.
...
<CssTextField
inputRef={(c) => {this.myRefs.username = c}}
label="Username"
placeholder="xxxxxxx"
margin="normal"
className={classes.textField}
variant="outlined"
fullWidth
/>
...
Then Access value like this.
onSaveUser = () => {
console.log('Saving user');
console.log(this.myRefs.username.value);
}
Here's the simplest solution i came up with, we get the value of the input created by material-ui textField :
create(e) {
e.preventDefault();
let name = this.refs.name.input.value;
alert(name);
}
constructor(){
super();
this.create = this.create.bind(this);
}
render() {
return (
<form>
<TextField ref="name" hintText="" floatingLabelText="Your name" /><br/>
<RaisedButton label="Create" onClick={this.create} primary={true} />
</form>
)}
hope this helps.
In 2020 for TextField, via functional components:
const Content = () => {
...
const textFieldRef = useRef();
const readTextFieldValue = () => {
console.log(textFieldRef.current.value)
}
...
return(
...
<TextField
id="myTextField"
label="Text Field"
variant="outlined"
inputRef={textFieldRef}
/>
...
)
}
Note that this isn't complete code.
The strategy of the accepted answer is correct, but here's a generalized example that works with the current version of React and Material-UI.
The flow of data should be one-way:
TextArea
s are populated from this initial statestate
via the handleChange
callback.state
is accessed from the onClick
callback---right now it just writes to the console. If you want to add validation it could go there.import * as React from "react";
import TextField from "material-ui/TextField";
import RaisedButton from "material-ui/RaisedButton";
const initialState = {
error: null, // you could put error messages here if you wanted
person: {
firstname: "",
lastname: ""
}
};
export class MyForm extends React.Component {
constructor(props) {
super(props);
this.state = initialState;
// make sure the "this" variable keeps its scope
this.handleChange = this.handleChange.bind(this);
this.onClick = this.onClick.bind(this);
}
render() {
return (
<div>
<div>{this.state.error}</div>
<div>
<TextField
name="firstname"
value={this.state.person.firstname}
floatingLabelText="First Name"
onChange={this.handleChange}/>
<TextField
name="lastname"
value={this.state.person.lastname}
floatingLabelText="Last Name"
onChange={this.handleChange}/>
</div>
<div>
<RaisedButton onClick={this.onClick} label="Submit!" />
</div>
</div>
);
}
onClick() {
console.log("when clicking, the form data is:");
console.log(this.state.person);
}
handleChange(event, newValue): void {
event.persist(); // allow native event access (see: https://facebook.github.io/react/docs/events.html)
// give react a function to set the state asynchronously.
// here it's using the "name" value set on the TextField
// to set state.person.[firstname|lastname].
this.setState((state) => state.person[event.target.name] = newValue);
}
}
React.render(<MyForm />, document.getElementById('app'));
(Note: You may want to write one handleChange
callback per MUI Component to eliminate that ugly event.persist()
call.)
