    :onclick=>‘show_wait()’)%>


    2. <% end -%>
    3.

    4.
    9.

    And this is my searching.erb


    3. Loading

    5. please wait

    util_controller class

    1. def searching
    2. render :layout => false
    3. end

    and the last search.js

    1. function show_wait()
    2. {
    3. window.scroll(0,0);

    4. var wait_window_margin_height = 10;

    5. var wait_window_margin_width = 20;

    6. $('wall').style.width = getBrowserWidth() + "px";

    7. $('wall').style.height = getBrowserHeight() + "px";

    8. $('wait').style.top = wait_window_margin_height + "px";

    9. $('wait').style.height = getBrowserHeight() -

    (wait_window_margin_height * 2) + “px”;
    10. $(‘wait’).style.left = wait_window_margin_width + “px”;
    11. $(‘wait’).style.width = getBrowserWidth() -
    (wait_window_margin_width * 2) + “px”;
    12. $(‘wall’).show();
    13. }
    14.
    15. function hide_wait()
    16. {
    17. $(‘wall’).hide();
    18. }
