How to prevent select on input text field with JavaScript?

To prevent select on input text field with JavaScript, we can set the input’s selectionStart property to the value of the input’s selectionEnd property.

For instance, we write:

<input>

to add an input.

Then we write:

const input = document.querySelector('input');
input.onselect = (e) => {
  e.target.selectionStart = e.target.selectionEnd;
}

to select the input with querySelector.

Then set the input.onselect property to a function that sets e.target.selectionStart to e.target.selectionEnd to set the selection range to length 0 to prevent selection.
