                        $.post('search.php', {search_query: search_query},function(searchq){

ロード時に動作します：

$(document).ready(function(){
                        var search_query=$(this).val();
                        $.post('search.php', {search_query: search_query},function(searchq){
                        $('#search_query').html(searchq);
                    });
