I want to change default value of TextField when state change but it doesn't work. I guess it is doesn't re-render.
<TextField
multiline={true}
rows={15}
disabled
id="outlined-basic" label="" variant="outlined"
defaultValue={!isEn?data.data[0].description:data.data[0].descriptionLocalization.en}
/>
<Button style={{position:"absolute",right:"20px",bottom:"5px"}} onClick={changeStateIsEn}>Save</Button>}
Default value is not meant to be changed with state.
You should set the value for reflecting the default value
<TextField
multiline
rows={15}
disabled
id="outlined-basic"
label=""
variant="outlined"
defaultValue="Something that will stay there initially only"
value={!isEn ? data.data[0].description : data.data[0].descriptionLocalization.en}
/>
There are two parts missing to your TextField component that is required to tie the input to state.
As user Mohammad Fasial said, the defaultValue prop is only for the default value the component will have. The correct prop you're looking for is value. State will need to equal value.
To listen for changes when the user inputs new information into the TextField input, you'll need to use the onChange prop. The onChange prop (on change listener) let's you provide a function as an argument to run when the input value changes. In this case we want to set onChange to run setExampleState to set the state to the value of the input field by using the event.target.value property.
function ExampleComponent(){
const [exampleState, setExampleState] = useState([]);
...
return (
<>
<TextField
multiline={true}
rows={15}
disabled
id="outlined-basic" label="" variant="outlined"
defaultValue={!isEn?data.data[0].description:data.data[0].descriptionLocalization.en}
value={exampleState}
onChange={(event) => setExampleState(event.target.value)}
/>
<Button style={{position:"absolute",right:"20px",bottom:"5px"}} onClick={changeStateIsEn}>Save</Button>
</>
);
}
To learn more about the different properties TextField has, you can look at the TextField API Documentation. There are also a lot of TextField code examples that can be expanded on the Material-UI site as well.

I have problem using react-hook-form v7 + material-ui textfield. The defaultValue working if I set autoFocus or I manually change the textfield value. However if I just submit without mouse click on the filed that not autoFocus, the defaultValue disappeared during the form submit. Please check codesandbox link
Test 1: don't touch anything, click submit, you will see submit value only has title but missing name and desc
Test 2: mouse click or change value in name, you will see after submit the value of name is there
My question is how to make this default value always submit even though without mouse click or change the value of the textField?
Please help and thanks in advance
To use Material-ui with react-hook-form. It is better to wrap it with Controller to allow react-hook-form to link with the 3rd party library element.
https://react-hook-form.com/api/usecontroller/controller
Wrap Textfield with Controller
const { handleSubmit, control } = useForm();
...
<Controller
render={({ field }) => (
<TextField
autoFocus
margin="dense"
id="title"
label="Title"
type="text"
fullWidth
{...field}
/>
)}
control={control}
name="title"
defaultValue={data.title}
/>
...
After that, the default value will be able to work as expected.
Here is the codesandbox for demo.
I would like to know how to update inputProps in textfield based off another prop,
<TextField
name={props.name}
value={props.vals}
inputProps={{autocapitalize:"characters", textTransform:"uppercase"}}
onChange={props.getStuff}
/>
I also have a prop that is designed to check if the textfield should display everything in all caps or not !
setAllCapital = true
I would like it so if setAllCapital is true the input props is given the autocap and text transform, but if its false then it is not given anything.
What is the convention/best way to do this ?
Thank you
You can pass the input props based on condition
<TextField
name={props.name}
value={props.vals}
inputProps={props.setAllCapital ? {autocapitalize:"characters", textTransform:"uppercase"} : "whatever value you want"}
onChange={props.getStuff}
/>
Now whenever your setAllCapital is false, you won't be sending autocap and textTransform to TextField.
Edit:
And a much more concise way would be
<TextField
name={props.name}
value={props.vals}
inputProps={props.setAllCapital && {autocapitalize:"characters", textTransform:"uppercase"}}
onChange={props.getStuff}
/>
Now your input props will be undefined if setAllCapital is false
One of the ways is to check the condition inline and pass the props. If props.setAllCapital is false then nothing gets passed to inputProps.
<TextField
name={props.name}
value={props.vals}
inputProps={props.setAllCapital ? {autocapitalize:"characters",
textTransform:"uppercase"}:undefined}
onChange={props.getStuff}
/>
I use material UI and a field text of type TextField. But when I was seized in my field email, the seizure does not appear to the screen and the value does not change in the email field.It always remains the same value.
Handle change is not working. the value is not passing to the handleChanges remains the same value
<TextField fullWidth={true}
className={classes.margin}
label={<FormattedMessage id="LoginTemplate.email" defaultMessage="Email" />}
id="email"
ref="email"
name="eamil"
type="email"
value={authentification.email}
onChange={this.handleChange}
InputProps={{
endAdornment: (
<InputAdornment position="end">
<Email className={classes.inputIconsColor} />
</InputAdornment>
),
}}
/>
Here is the code. Correct me What is the issue in that
Thanks in Advance.
In order to make the value change, you need to change a state (in the screen or external).
For instance (with bad performance but just to explain):
add to your cunstrunctor if exists:
constructor(props) {
super(props);
this.state = {
emailInputText: undefined //or empty string
}
}
Then change TextField component value and onChange props to:
value={this.state.emailInputText}
onChange={(text) => this.setState({emailInputText: text})}
I will consider to remove the ref='email'.
I'm trying to change the value of Material-UI's TextField when it focuses. It seems that I can do that through inputProps, but I can't find any example of how to implement that.
add onFocus prop with TextField
<TextField value={this.state.value} onFocus={onFocus} label="Custom CSS" variant="outlined" id="custom-css-outlined-input" />
then handle the onFocus event
const onFocus = () => {
this.setState({
value:'new value'
})
}
it should update the value in the field when focus comes on the text field
In default semantic-ui we can do this option: https://github.com/Semantic-Org/Semantic-UI/commit/b4ae26d24f75886c3d5f6fc4f00e176f09705a13
But, how to do it in semantic-ui-react? Google nothing say about it, please, I need help.
What I'm trying to achieve:
I'm using redux-form. In my form present semantic component <Form.Select multiple ....> and after success submit - call to redux-form method reset. All is fine, form is clear... but not dropdown/select field. Any ideas?
I solved the problem as follows:
Semantic-ui-react props value set to the current value of the field.
<Form.Select
name={input.name}
options={options}
label={label}
placeholder={placeholder}
search
multiple
selectOnBlur={selectOnBlur}
onFocus={::this.handleFocus}
onBlur={::this.handleBlur}
onChange={::this.handleChange}
defaultValue={defaultValue || []}
value={input.value}
loading={loading} />
