What I want to accomplish is a textInput that show a text like (0/255) in the side of itself.
The minimal code for the component:
import React, { useState, useEffect} from 'react';
import { View, TextInput, Text } from 'react-native';
export default function InputWithIndicator({ Limit, ...otherProps }) {
const [charRemains, setCharRemains] = useState(0);
const [TextValues, setTextValues] = useState('');
const [TextLimit] = useState(Limit);
useEffect(() => {
setCharRemains(Limit-TextValues.length);
});
return (
<View >
<TextInput {...otherProps} onChangeText={value=>setTextValues(value)}/>
<Text>
{charRemains}/{TextLimit}
</Text>
</View>
);
}
To place the component in code:
<InputWithIndicator placeholder="Your name" maxLength={25} Limit={25} onChangeText={value=>setName(value)} />
It works nice as component to display. But the major problem is the onChangeText does not return any value at all. Is there any way? FYI, I have tried with onChange Event, too.
Use onChange
instead fo onChangeText
Take a look at my sample: Sample
