I am adding dynamically input fields.I want to get it's value .can you please tell me how I will get it's value
here is my code https://codesandbox.io/s/adoring-meninsky-hu3f8
return (
<div className="App">
<Form>
{state.inputs.map(input => (
<KeyValue />
))}
<Button type="button" primary onClick={appendInput}>
Add
</Button>
</Form>
</div>
);
I want to get it's value how ?
any update
Here is my solution https://codesandbox.io/s/pensive-lake-erynd
pass function to KeyValue component to get values when input changes
const handleChangeKeyValues = name => value => {
setState(prevState => {
const newValues = {
...prevState.values,
[name]: value
};
return {
...prevState,
values: newValues
};
});
};
and receives values from props and handle inputs in KeyValue component
const KeyValue = ({ onChange, values = { firstName: "", lastName: "" } }) => {
const handleChangeInput = event => {
const { value, name } = event.target;
const newFormValue = { ...values, [name]: value };
onChange(newFormValue);
};
return (
<Form.Group widths="equal">
<Form.Input
value={values.firstName}
fluid
label="Key"
name="firstName"
placeholder="First name"
onChange={handleChangeInput}
/>
<Form.Input
value={values.lastName}
fluid
label="Value"
name="lastName"
placeholder="Last name"
onChange={handleChangeInput}
/>
<Icon style={{ top: 30, position: "relative", left: 10 }} name="delete" />
<Form.Input
style={{ display: "none" }}
fluid
label=""
placeholder="Last name"
/>
</Form.Group>
);
};
Store values in state under unique name for each inputs
I will put a name for each input and pass it a onChange function. Then in my onChange function i will set my State depend on the name.
Function
onChange = e => {
this.setState({[e.target.name] : e.target.value});
}
Render
render(){
return (
<div className="App">
<Form>
{state.inputs.map(input => (
<KeyValue name={input.name} value={this.state[input.name]} onChange={this.onChange } />
))}
<Button type="button" primary onClick={appendInput}>
Add
</Button>
</Form>
</div>
);
}
