How can we display the final section of the input text once it loses focus?

Question

How can we display the final section of the input text once it loses focus?

When inputting text, the right side of the text is hidden when we focus out or click outside the input field. I want to reverse this so that the left side is hidden and only the right side shows.

<input value="abcdefghijklmnopqrstwxyz123456789">

In the example above, we can see "abcdefghijklmnopqrstwxyz1" with the rest ("23456789") hidden. However, I want to display "klmnopqrstwxyz123456789" (the last part instead of the first part) and hide the initial part "abcdefghij" without using CSS direction.

By utilizing JavaScript, we can accomplish this task by making use of the blur event.

When the blur event is triggered, we capture the current Element.scrollLeft of the input field. Afterwards, we reset the scrollLeft position to Element.scrollWidth enclosed within a setTimeout() function to ensure that the browser delays rendering the pending change.

const elem = document.getElementById('data');

elem.addEventListener("blur", () => {
  setTimeout(() => {
    elem.scrollLeft = elem.scrollWidth;
  }, 0);
});

<input id="data" value="abcdefghijklmnopqrstwxyz123456789">

The following code snippet is designed to dynamically adjust the length of text based on its content:

function updateTextSize(input){
    input.size = input.value.length;
    console.log(input);
}

<input type="text" onkeyup="updateTextSize(this)" value="abcdefghijklmnopqrstwxyz123456789">
