A guide to displaying the beginning content of an HTML input element programmatically in React, specifically focusing on cases where the text exceeds the width of the input

My input element initially contains the value 'abcdefghijklmnopqrstuvwxyz'

I utilized ref to highlight the characters from 'n' to 'z'

inputRef.current.setSelectionRange(18, 26);

This code snippet results in the following:

How can I dynamically change the input value to this instead?

Further information:

If I switch to another tab and then return to the tab with the input field, it displays the desired outcome. However, I am unsure how to achieve this using code.

Answer №1

If you're looking to utilize the Element.scrollLeft attribute with good browser support, you can check out this Codesandbox example: https://codesandbox.io/s/flamboyant-panini-02gr7l?file=/src/App.js

In my implementation, I've incorporated timeouts to set up the scenario. The crucial part is ensuring it fires after the setSelectionRange call.

setTimeout(() => (ref.current.scrollLeft = 0), 100);

Keep in mind that the timing for timeouts can vary slightly depending on the circumstances.
