Javascript – Remove leading zeros from input type=number

htmlinputjavascriptnumbersvalidation

I noticed that if i use <input type="number" /> the leading zeros are not removed. I also saw a lot of discussion on how keeping leading zeros.

For example "000023" and "23" are the same number and i think that it doesn't make sense keeping those zeros.

I'm going to give an example with react usage. It uses state which store the value of the field. But, I think u can replace it with whatever variable you like.

<input type='number' value={Number(this.state.myNumber).toString()}/>

In my case, myNumber stores a year number. This way, the year 2018 (for example) won't be displayed mistakenly as 02018.
