Space before sentence and after sentence?

I've got this script:

<input type="text" name="lastnamename" pattern="[^\s]*" title="Delete space before or after sentence!" style="text-transform:uppercase" required>

This pattern "[^\s]*" shows every spaces which has been made in sentence _Adam_Sandler_. I need pattern which shows only _Adam Sandler_ these spaces BEFORE SENTENCE, AND AFTER SENTENCE.
