How to Scroll to the End of a Long Text Input in HTML?

Scrolling to the End of a Long Text Input: A Detailed Solution

In the world of web applications, it's common to encounter text input fields that accommodate lengthy URLs. While this provides sufficient space for URLs, it often results in the beginning of the URL being displayed, while the more informative end remains hidden.

The Challenge:

Navigating through such long URLs in a text field becomes a tedious task, as users have to scroll manually to reach the end. To alleviate this inconvenience, developers have sought a solution that allows them to "scroll" directly to the far right of the URL. This eliminates the need for manual scrolling and provides immediate access to the URL's end.

The Answer:

Thankfully, the HTMLInputElement.setSelectionRange() method offers a solution to this challenge. By explicitly setting the focus() on the input field and subsequently setting the selectionRange() to the length of the input value, the cursor is automatically positioned at the end of the URL.

Implementation:

<code class="javascript">var foo = document.getElementById("foo");
foo.value = "http://stackoverflow.com/questions/1962168/scroll-to-the-very-right-of-a-long-text-input";
foo.focus();
foo.setSelectionRange(foo.value.length, foo.value.length);</code>

Note:

It's important to note that this solution is applicable to all browsers except IE6-8 and Opera. In these specific browsers, the cursor may return to the beginning of the field when the input loses focus.
