Jquery show/hide div by clicking on button which has the same value

I add dynamic in a loop buttons and divs in php and I want to show/hide only this div which has the same value as button while clicking on button. Div is hidden by css.

while (($entry = readdir($handle)) !== false) {
    if ($entry != '.' && $entry != '..') {
        echo "<input type=\"submit\" value=\"$entry\" class=\"button\">";
        echo "<p id=\"mydiv\" value=\"$entry\"></p>";
    }
}
