How to remove input default zero value when onChange?

Issue

I use chakra-ui input

https://chakra-ui.com/docs/components/input/usage

import { Input } from '@chakra-ui/react';

const [shareInputValue, setShareInputValue] = useState(0);

                        <Input
                            type="number"
                            textAlign={'center'}
                            borderRadius={0}
                            border="1px solid #E2E8F0;"
                            value={shareInputValue}
                            onChange={e => {
                                const enterValue = e.target.value;
                                console.log('enterValue', enterValue);
                                const removeZeroStartValue = enterValue.replace(/^0+/, '');
                                console.log('removeZeroStartValue', removeZeroStartValue);
                                setShareInputValue(Number(removeZeroStartValue));
                            }}
                        />

When I type 1 the Input will show 01 and continue to type 1 the Input will show 011

I think it should become 1 and 11 ?

I try to use removeZeroStartValue and then setState, but it's not working

How to fix the issue ?

Solution

You're directly setting the value to 0 in your default state. Set it to null and add a placeholder instead.

const [shareInputValue, setShareInputValue] = useState(null);


  

  <Input
      type="number"
      textAlign={"center"}
      borderRadius={0}
      border="1px solid #E2E8F0;"
      placeholder="0"
      value={shareInputValue}
      onChange={(e) => {
        setShareInputValue(e.target.value);
      }}
    />
