            <div id="listInfoBlock" class="list_infoBlock">           

            </div><!-- .list_infoBlock-->

Answer 1

Your page is reloading because that's the standard browser 's behavior when the user clicks on a a (link) HTML element.

You can stop this default behavior by using a parameter in the click handle and calling the preventDefault method :

$("#buttonFindFilmByName").click(function(e) {
    e.preventDefault();
    ....

Answer 2

Return false from the click handler function to tell the browser not to follow the link. This also allows you to set a real link in href for browsers that don't support JavaScript, or in case the user turned it off.

$(document).ready(function () {
  $("#buttonFindFilmByName").click(function() {
    $('#listInfoBlock').load('cinema/filmlist');
    return false; // <====== FIX
  });
});
