## How to Position the Viewport of a Text Input Field to Show the End of a Long String?

Positioning Text Input Field's Viewport

Many applications require an input field to display long strings, such as URLs. Unfortunately, default browser functionality displays the beginning of a string in the input field's viewport, which may not be the most user-friendly.

To address this issue, modern browsers except IE6-8 and Opera offer a solution using HTMLInputElement.setSelectionRange(). After explicitly setting the focus(), the selection range can be set to the length of the input value. This action effectively scrolls the viewport to the end of the input, ensuring that the user sees the rightmost portion of the string.

While this approach provides a seamless scrolling experience, it comes with a slight drawback. Once the input field loses focus, the viewport snaps back to the start position. Nevertheless, for many applications, this adjustable viewport position significantly enhances the user experience when navigating long strings in an input field.
