            url:"fetch.php",
            data:"q=" + txt,
            success:function(data)
            {
                $("#search_result").html(data);
            }
        });
    });
});
</script>

Answer 1

$("search_result").show();

should be

$("#search_result").show();

and as mentioned

type="GET",

should be

type: "GET",

What is the php code returning? And what are the console errors?

Answer 2

type="GET"应type: "GET"
